You’ve bought an electric vehicle. Bet you’re feeling pretty good about skipping the petrol station! But if you’re now stuck waiting in line at a public charging station, it’s a bit of a letdown, right?

The answer? An EV charger installed at your home or business. 

Choosing the right EV charger can be overwhelming. Heaps of options. Confusing specs. And no clear answer on what suits your home, your business, or your daily driving routine.

This EV charger comparison guide cuts through the noise. We’ve compared top EV charger models to reveal the best EV charger with the speed, features, and value you need.

Why Choosing the Right EV Charger Matters

Choosing the right EV charger will make your life easier. You can charge faster, avoid long waits at public stations, and schedule charging during off-peak times when electricity rates are cheaper to save money. 

Smart chargers come with built-in features like energy tracking, remote access via an app, and automatic scheduling, so you’re in complete control wherever you are.

Certain chargers are designed to work with certain setups. For example, some are made for homes with standard single-phase power, while others support faster charging through three-phase connections. If you have solar panels, you’ll want a charger that can sync with your solar system and charge your EV using excess solar energy.

With a smart charger, you can take this a step further, automatically prioritising solar power, tracking how much energy you’re using, and adjusting charging times to lower costs and reduce your reliance on the grid.

And don’t forget compatibility. Not every charger suits every EV model, so it’s important to pick one that’s a good match for your car and your home or business power supply. A little research now means fewer headaches later and more reliable charging every time you plug in.


Types of EV Chargers – A Quick Overview

Level 1 Chargers

Level 1 chargers are the most basic charger type and usually come included with your EV. They plug into a standard 240-volt (V) household power point and deliver around 2.4 kW of power.

That translates to slow charging. You’re looking at around 14–24+ hours for a full charge, depending on your vehicle. It’s enough to top up overnight if you don’t drive far each day, but it’s not ideal for regular use or EVs with larger batteries.

These chargers are simple, portable, and cost nothing extra upfront. But if you want faster, smarter, or solar-compatible charging, you’ll likely outgrow a Level 1 charger quickly.

Level 2 Chargers

Level 2 chargers are the most popular choice for home and business use. They need to be hardwired or plugged into a dedicated circuit, usually using a 7 kW (single-phase) or 22 kW (three-phase) setup.

Charging is much faster than with a Level 1 charger. You can expect a full charge in 4–10 hours, depending on your EV and your power supply. They’re ideal for complete overnight charging or topping up during the day.

Many Level 2 chargers come with smart features like Wi-Fi connectivity, energy monitoring, scheduling, and solar integration. They’re compatible with most EV models and offer a more reliable, long-term solution for regular charging at home or work.

DC Fast Chargers

Most homes and businesses supply AC (alternating current), which needs to be converted to DC (direct current) because EV batteries only use DC power. With a Level 1 or 2 charger, the current is converted inside the car using its onboard inverter. With a DC fast charger, this conversion happens inside the charger.

This process speeds up charging, making DC fast chargers the fastest type of charger. 

They offer high power output, typically ranging from 25 kW to 350 kW. Lower-powered models (around 25–50 kW) can give you a decent top-up in under an hour. Higher-powered units (150–350 kW) can charge some EVs from 10% to 80% in just 20–60 minutes, depending on the car’s battery capacity and charging capability.

DC fast chargers are used at commercial sites, fleet depots, and public charging stations. They’re more expensive to buy and install, and generally require three-phase power, advanced electrical infrastructure, and council approval. Most homes won’t support them, but for businesses, they’re a game-changer for fast charging turnaround.

Single-Phase vs Three-Phase EV Chargers

What power supply does your home or business have: single-phase or three-phase? The answer will affect the EV charger you choose. The terms refer to how electricity flows into your home or business.

Most homes in Australia have single-phase power. It’s suitable for everyday appliances and supports EV chargers up to around 7.4 kW. Three-phase power is more common in commercial buildings or large properties and can support higher-capacity chargers, up to 22 kW or more.

The main difference between single-phase and three-phase charging is speed. With single-phase, a typical charger will add about 25–40 km of range per hour, depending on your EV. With three-phase, charging speeds can jump to around 60–100+ km of range per hour.

In terms of cost, single-phase chargers are generally cheaper to install and more than enough for most home users. Three-phase chargers and the required wiring cost more but are faster and better suited for heavier daily use, such as in businesses, workplaces, or apartment blocks.

Still unsure? A licensed electrician can confirm your home or business’ power supply and determine if any upgrades are needed for three-phase charging.

Key Features To Look For in an EV Charger

When choosing an EV charger, it’s not just about speed. 

Here are the key features to keep in mind.

  • Durability: Look for a charger that can handle Australian conditions—heat, rain, and everything in between. For outdoor setups, weatherproof casing is essential.
  • Compatibility: Make sure the charger works with your EV model and your power setup (single-phase, three-phase, or solar). Also, consider how you want to connect the charger to your car; some are tethered, with a cable attached, while others are untethered, so you’ll need to use the charging cable that came with your EV and plug it into the charger each time.
  • Integration with Solar Systems: If you have solar panels, pick a charger that can sync with your system. The best ones let you prioritise solar power, helping you save money and reduce grid reliance.
  • Smart Capabilities: Many chargers now come with apps that let you schedule charging during off-peak hours, monitor energy use, or receive software updates automatically. Some also support load management to avoid overloading your home or business’ power.
  • High Capacity for Multiple Vehicles: If you’re running a fleet or offering public charging, look for chargers that can support multiple vehicles at once or work together using power-sharing features.
  • Payment Integration: For customer use, choose a charger with built-in or add-on payment options like RFID cards, tap-and-go, or mobile apps. These make charging simple and trackable.
  • Warranty and Support: A solid warranty (ideally 3 years or more) gives peace of mind. Also, check that the brand offers local support and installer access if something goes wrong.

What Is an EV Charger? Types, Charging Speeds, and How They Work

EV sales are surging year after year, with more Aussies going electric than ever before. Are you one of them? Whether you drive an electric vehicle for the savings, the sustainability, or the tech appeal, one thing’s for sure: charging matters.

From powering up at home to installing charging stations at your business, knowing your charging options can save you time, money, and a whole lot of hassle.

What is an EV charger, and what do you need to know about it? We’ll cover the different types available, how they work, and how fast they charge so you can choose the best setup.


What Is an EV Charger?

An EV charger is a device that transfers electricity into an electric vehicle’s battery, allowing it to recharge and power the car’s motor. 

How Does an EV Charger Work? EV Charging Basics

  1. The charger draws electricity from your home or business’ electricity source, be it the grid or solar panels.
  2. Most homes and businesses supply AC (alternating current), which needs to be converted to DC (direct current) because EV batteries only use DC power. An inverter steps in to do the job, either inside the charger (for DC fast chargers) or inside the car using its onboard inverter.
  3. The converted electricity is then sent through the charger and into your EV’s battery.


Types of EV Chargers

Level 1 Chargers

Level 1 chargers are the most basic type and come standard with most electric vehicles. They plug into a regular 240-volt (V) household power outlet, so there’s no special installation needed.

They’re the slowest charging option, but provide enough for overnight charging if you drive short distances.

Level 1 chargers can be a practical option for plug-in hybrid vehicles. Since hybrids have smaller batteries than full EVs, they don’t take as long to recharge, making a standard outlet more than capable of topping them up.

Level 2 Chargers

Level 2 chargers are faster and more powerful than Level 1 chargers. They require a dedicated 230–240V circuit, similar to what large appliances like ovens or air conditioners use, and usually need to be installed by a professional.

These chargers are compatible with most EVs and plug-in hybrids and are ideal for daily home use or for businesses looking to offer EV charging to staff or customers.

EV charging standards in Australia are shifting toward smart chargers as the new normal. Many Level 2 chargers can monitor energy usage, allow you to schedule charging during off-peak times when electricity is cheaper, and even integrate with solar systems to maximise efficiency. All this helps you lower costs, reduce grid reliance, and keep your EV ready when you need it.

Fast Chargers (DCFC)

DC fast chargers (DCFC) are the quickest way to charge an EV. Unlike Level 1 and Level 2 chargers, which supply AC power, DC fast chargers deliver electricity in DC form directly to the battery, skipping the vehicle’s onboard inverter.

They require a high-voltage, three-phase power supply and are installed in commercial or public locations like shopping centres, service stations, or highway rest stops. They service commercial vehicles making long trips or fleet vehicles needing quick turnarounds.


Understanding EV Charging Speeds

EV charging speed is measured in kilowatts (kW), which refers to how quickly electricity is transferred to your vehicle’s battery.

Charging speed depends on two main factors: an EV’s maximum charging capacity and the size of its battery.

Every EV has a built-in limit on how much power it can accept at once. So even if you plug into a high-powered charger, your car will only draw what it’s designed to handle.

For example, if your EV has a 7 kW onboard charger, it won’t charge any faster than 7 kW, even if you’re using a 22 kW charger. On the flip side, if your EV can accept 11 kW but you’re using a 7 kW charger, it will charge at the lower 7 kW speed.

EV batteries are measured in kilowatt-hours (kWh), which indicates how much energy they can store. A larger battery takes longer to fully charge than a smaller one.

Charging time is a mix of how fast power flows (kW) and how much energy your battery can hold (kWh). Matching your charger to your vehicle’s capabilities helps you get the best results.

How Do Solar Batteries Work?

How do solar batteries work?

As more households look to cut their energy costs and reduce their reliance on the grid, solar batteries are stepping into the spotlight. 

For solar installers, they’re no longer just an optional add-on; they’re becoming a key part of the conversation. And for customers, they’re a way to take control of how and when they use solar power.

Whether you’re an installer explaining battery options or a homeowner weighing up your solar investment, it’s important to understand the answer to the question: “How do solar batteries work?”

Then, you’ll be in a better position to compare products, understand their benefits, and make informed decisions that suit each home’s energy needs and budget.

What Are Solar Batteries, and How Do They Work?

Solar batteries are energy storage systems designed to hold excess electricity generated by solar panels. Instead of sending unused solar power back to the grid, these batteries store it for later use, like at night, during cloudy days, or when there’s a blackout.

How do solar batteries work? Here’s the process.

  1. Power Generation: During the day, solar panels absorb sunlight and generate direct current (DC) electricity.
  2. Power Conversion: A hybrid inverter converts that DC electricity into alternating current (AC) power for use in the home. At the same time, it directs any extra energy into the solar battery for storage.
  3. Power When Needed: When the sun goes down or a home’s energy use spikes, the house automatically draws power from the battery first, reducing the need to buy electricity from the grid.

Solar Inverters: A Solar System’s Traffic Controller

A solar inverter plays a crucial behind-the-scenes role in any solar and battery setup. It manages the flow of electricity between the solar panels, the battery, and the home’s appliances.

First, it converts the electricity coming from the panels (which is in DC form) into AC electricity, which is what most appliances run on.

If there’s more solar energy than the household needs at that moment, the inverter sends the excess power to the battery for storage. Later, when energy is needed and the sun is not shining, the inverter sends stored power from the battery to the home.

A solar inverter constantly switches between sources, making decisions in real-time about where electricity should go. Without it, a solar battery system wouldn’t be able to function properly.

Types of Solar Batteries and How They Function

Battery TypeWhat It IsHow It WorksPros Cons
Lithium-IonThe most common battery type for home solar systemsUses lithium compounds to store and release energy through chemical reactionsHigh efficiency, long lifespan, compact size, fast chargingHigher upfront cost
Lithium Iron Phosphate (LiFePO₄)A subtype of lithium-ion, known for thermal stability and safetySimilar to standard lithium-ion but uses iron phosphate for better stability and longevitySafer, longer cycle life, resistant to overheating. The preferred choice for most households. Used at iStoreSlightly bulkier than other lithium batteries due to lower energy density. Only a problem if space is limited or a more compact setup is preferred
Lead-Acid (Flooded and AGM)Traditional battery type, often used in off-grid systemsStores energy using lead plates and a liquid or gel electrolyteLower upfront cost, widely available, simple techShorter lifespan, lower efficiency, bulky, requires ventilation or maintenance (flooded)
Flow BatteriesEmerging tech, mostly used in commercial settings for nowStores energy in external tanks using liquid electrolytes that flow through a cellVery long lifespan, scalable capacity, easy to recycleExpensive, large physical footprint, not yet widely used in homes
SaltwaterNewer, eco-friendly battery optionStores energy using saltwater electrolytes rather than heavy metalsNon-toxic, recyclable, no risk of fire or overheatingLarger size, lower availability, lower energy density

Key Benefits of Solar Batteries for Homeowners

If you’re an installer trying to convince your clients they need a solar battery, or you’re a homeowner investigating whether it’s worth getting one, here are the benefits to consider.

  • Energy Independence: Reduces reliance on the grid by storing excess solar power for later use, especially during peak times when electricity prices are higher or when outages occur.
  • Lower Electricity Bills: Helps cut power costs by using stored solar energy instead of buying electricity from the grid.
  • Backup Power: Keeps essential appliances running during blackouts or grid failures, for peace of mind.
  • Environmental Impact: Makes better use of clean, renewable energy and reduces overall carbon footprint.
  • Scalability: Allows homeowners to start small and expand their battery storage as their energy needs grow or budgets allow, e.g. installing more solar panels or buying an electric vehicle.

The Solar Battery Charging and Discharging Process

During the day, when solar panels generate more electricity than the home needs, the excess energy is sent to the battery. This is known as charging. The battery stores this energy instead of it being sent back to the grid.

At night, on cloudy days, or during power outages, the battery discharges, supplying that stored energy to keep appliances and lights running. The home automatically draws power from the battery first before turning to the grid.

An important factor in this process is the Depth of Discharge (DoD), which refers to the percentage of the battery’s stored energy that can be used before it needs to be recharged. For example, a battery with a 90% DoD can safely use up to 90% of its capacity each cycle. 

A higher DoD means more of the battery’s stored energy can be used each day. However, discharging too much too often can reduce the battery’s lifespan. It’s about finding the right balance between daily use and long-term durability.

Factors That Affect Solar Battery Performance

  • Battery Type: Different battery chemistries, such as lithium-ion, lithium iron phosphate, or lead-acid, offer varying levels of efficiency, lifespan, and storage capacity. At iStore, we use lithium iron phosphate (LiFePO₄) batteries, as they tend to last the longest, with more charge cycles than standard lithium-ion or lead-acid batteries.
  • Temperature: Extreme heat or cold can impact battery performance and longevity, especially if the system isn’t installed in a temperature-controlled space.
  • Usage Patterns: Frequent deep discharges or irregular charging can wear out the battery more quickly, while consistent, moderate use supports a longer lifespan.
  • System Integration: Performance improves when batteries are paired with compatible inverters, proper wiring, and smart monitoring tools (like the iStore WLAN dongle) that manage energy flow efficiently.

FAQs

How Do Batteries Work With Solar Panels?

Solar panels generate electricity during the day and power the home first. If there’s extra energy, the system sends it to the battery for storage. When the sun goes down or energy demand rises, the battery releases the stored power to keep appliances and lights running. 

A hybrid inverter actively manages the flow between the panels, battery, and home to make sure everything works smoothly.

How Do Solar Batteries Work in Australia?

Solar batteries store excess solar energy generated by rooftop solar panels during Australia’s renowned sunny days and supply that power when the sun isn’t shining. 

Our long sunny days, extreme summer heat, and occasional blackouts from storms make solar batteries particularly useful here. 

How Long Will a 10 kW Battery Last?

A 10 kW battery can typically power an average home for 8–12 hours, depending on energy usage. It may last longer if used only for essential appliances, and shorter if multiple high-energy appliances are running simultaneously.

What Happens to Solar Power When Batteries Are Full?

When a solar battery is fully charged, any excess solar power is sent back to the grid or, in some systems, redirected to power non-essential appliances. This process prevents energy from going to waste while keeping the battery protected from overcharging.

Do Solar Batteries Recharge Themselves?

No, solar batteries don’t recharge themselves. They rely on excess electricity generated by solar panels during the day to charge. Without solar input or grid charging (if supported), the battery won’t refill.

Maximise Your Energy Independence with iStore Solar Batteries

So, you’ve made the switch to an electric vehicle (EV), or you’re seriously thinking about it. Excellent! EVs are quiet, clean, and cheaper to run: no petrol stops, no oil changes, just smooth rides and lower bills.

But driving electric is only half the story. The real game-changer? Charging at home. No more fighting for a spot at the local charging station or waiting around while your battery crawls from 20% to “almost there.” With an EV wall charger, your garage becomes your personal recharging station: fast, smart, and convenient.

How can you choose the right EV wall charger for your car, home, and lifestyle?

This iStore guide will tell you everything you need to know!

What Is an EV Wall Charger and How Does It Work?

An EV wall charger is a device that lets you charge your EV from home using your household power supply. You can mount it on a wall in your garage, carport, or driveway. 

All EVs come with a basic charger, often called a Level 1 charger. This charger plugs into a standard power point, like your toaster or phone charger would. But it’s quite slow, taking 12–20 hours, or even longer, to fully recharge your EV’s battery. 

Alternatively, Level 2 chargers are dedicated wall units that use a higher voltage to deliver power much faster. Depending on your home’s electrical setup, a Level 2 charger can fully charge your EV in 4–10 hours. 

Most EV wall chargers connect directly to your home’s switchboard, drawing power through a dedicated circuit. 

Many EV wall chargers, like iStore’s are part of a solar energy product lineup, letting you charge your car using free, clean energy from the sun. Some systems can even prioritise solar energy first, so you’re not drawing from expensive grid electricity unless you need to. 

How to Choose an EV Wall Charger: Key Factors to Consider

Charging Speed

Charging speed refers to how fast your EV wall charger can add power to your EV’s battery. The higher the charging speed, the less time you need to plug in your EV.

Charging speed is measured in kilowatts (kW). A higher kW rating means faster charging. For example, a 7.2 kW Level 2 charger can typically add around 30 to 50 km of range per hour, depending on your vehicle. Compare that to a basic 2.4 kW Level 1 charger, which only adds 10 to 15 km of range per hour.

You must check how much power your EV can accept. Some vehicles cap out below 7.2 kW, so going for a higher-powered charger won’t necessarily speed things up.

Compatibility

You must also check how much power your home can handle. Most single-phase homes in Australia can support chargers up to 7.2 kW. Larger properties with a three-phase power supply can support chargers up to 22 kW. iStore’s EV chargers are available in either 11kW or 22kW so you can select the one most suitable for your home.

Choose a charger that delivers the maximum speed your home and EV can support, without overpaying for power you can’t use.

Then, there’s the plug. Not all EVs use the same plug. The EV wall charger you choose must match your vehicle’s connector. Most newer EVs use a Type 2 connector, which has become the standard. However, some older models or imports might use a Type 1 connector instead.

Check your EV manual or speak to your dealer before buying. Many chargers list which vehicle brands or connector types they support, so it’s usually easy to confirm.

Smart Features

Some EV wall chargers like iStores, come with smart features. One of the most useful is app control. With a connected app, you can start or stop charging from your phone, check how much charge your car has, or get alerts when it’s done.

Energy monitoring lets you see exactly how much electricity your EV uses, which is handy for tracking energy usage costs and managing your home’s overall energy usage.

Scheduling is another great feature. You can set your charger to only run during off-peak hours when electricity is cheaper. 

Some chargers are demand response ready, meaning they can automatically adjust charging during peak times if your electricity provider offers incentives. It’s a way to help balance the grid and lower your electricity bills.

Many chargers can also connect to smart home systems like Google Home or Amazon Alexa, so you can manage charging with voice commands or automate it as part of your home energy routine.

If you like convenience, control, and saving money, it’s worth looking for an EV wall charger with these smart features.

Durability and Safety

Your EV wall charger must be able to handle Aussie weather if you’re installing it outdoors. Choose a weatherproof model that resists rain, heat, and dust. Most chargers including iStore’s list an IP rating (like IP65), which shows how well the unit keeps out water and dirt. A higher number means better protection.

Safety is also important. A good EV charger should have built-in protections against overheating, short circuits, and power surges. These features help prevent damage to your car and home, especially during storms or power outages.

Check for certifications that show the charger has been tested to meet Australian safety standards. Look for things like RCM (Regulatory Compliance Mark) or other recognised approvals so you know you’re buying a reliable product.

Aesthetics

While performance matters most, the look of your EV wall charger is not to be overlooked, especially if it’s mounted in a visible spot like your driveway or garage wall. 

Some chargers have a sleek, modern design that will blend in with your home’s exterior, while others might stand out more than you’d like. Many brands also offer compact units with clean lines and neutral colours that won’t clash with your space. 

If visual appeal matters to you, take a moment to check the size, shape, and finish of the charger before buying.

Benefits of Installing an EV Wall Charger at Home

Convenience

Having a wall charger at home means you can plug in your EV when you get home and wake up to a full battery.

No trips to a public charger, no waiting in line, no wasting time. Just easy, reliable charging on your schedule.

Cost Savings

Charging your EV at home is often much cheaper than using public charging stations. Public chargers usually charge higher rates per kilowatt-hour, and some add session or connection fees. 

With a home EV wall charger, you can also take advantage of off-peak electricity rates, which are lower prices charged by your energy provider when demand is low (late at night or early in the morning). Many chargers let you schedule charging to start during these hours automatically, so you save money without lifting a finger.

Energy Efficiency

Pairing your EV wall charger with solar panels is incredibly energy efficient. Instead of drawing electricity from the grid, your charger can use the free energy your solar system produces during the day. If you also have a solar battery, you can store any extra generated solar energy and use it to charge your EV at night, maximising your solar savings.

This setup means you rely less on grid electricity, especially during peak times when prices are higher. You can charge your EV for next to nothing!

Using solar energy to charge your EV also helps reduce your carbon footprint with clean, renewable power instead of coal or gas-generated energy. 

Resale Value

An EV wall charger can make your home more appealing to future buyers as more people switch to electric vehicles. For EV owners, having a charger already installed is a big plus, saving them the cost and hassle of installing one.

EV Charger Incentives and Rebates Available in Australia

Some Australian state and territory governments offer incentives for installing residential EV chargers. 

In the Australian Capital Territory, eligible homeowners can get a loan from $2,000 to $15,000 to buy energy-efficient products, including electric vehicle charging infrastructure. This is a zero-interest loan, and homeowners have up to 10 years to repay it.

Over in the Northern Territory, the EV Charger Grants Scheme offers a $1,000 grant to EV owners for purchasing and installing a home charger.

Federal and state-based incentives for installing solar batteries can help make solar EV charging more accessible and affordable for Australians.

Starting July 1, 2025, the federal Cheaper Home Batteries Program offers up to a 30% reduction in the cost of home solar batteries, potentially saving households up to $18,600 or 30% off the cost of a home battery.

Various states provide additional incentives. For example, New South Wales offers up to $2,400 off the installation cost of a solar battery for homes and businesses with existing solar. 

How Much Does an EV Wall Charger Cost?

Most EVs come with a basic Level 1 charger. But if you want faster charging, you’ll need a dedicated Level 2 charger.

Level 2 EV wall chargers can range from $500 to $3,000. Installation, including labour and materials (wiring, circuit breakers), can cost between $700 and $1,500. So you can usually expect to pay $1,500-4500 for a Level 2 charger and installation. 

How to Install an EV Wall Charger

Installing a Level 1 EV wall charger doesn’t require professional help. Simply plug the charger straight into a standard household power point. You can then mount the charger on a wall using a basic wall bracket or cable hook, which is often included or easy to buy separately.

Installing a Level 2 charger is more involved and must be done by a licensed electrician. 

They will

  1. Inspect your switchboard and wiring. The electrician will check whether your switchboard can handle the extra load of an EV wall charger. They’ll look at your existing circuit breakers, wiring condition, and whether you have single-phase or three-phase power. Your switchboard may need an upgrade or a new circuit breaker installed.
  2. Plan and run a dedicated circuit. EV chargers require their own circuit, separate from other appliances. The electrician will run new cabling from your switchboard to the charger location. They’ll choose the safest and most direct route, avoiding interference with existing wiring or plumbing.
  3. Install a safety switch (RCD). A residual current device (RCD) must be installed to protect against electric shock or faults. This is a legal requirement in Australia.
  4. Mount the charger on the wall. Once the wiring is in place, the charger is mounted securely onto a solid surface using manufacturer-provided brackets. The location should be sheltered (if possible), easily accessible, and within reach of your EV’s charging port.
  5. Connect and test the system. The electrician will connect the charger to the power supply, test for faults, and make sure the unit complies with Australian safety standards (AS/NZS 3000). They’ll also issue a Certificate of Compliance, which confirms they performed the installation safely and legally.
  6. Integrate the charger with your solar system. If you have solar panels, the electrician can configure your EV wall charger to draw energy from your solar system when available. Some chargers also support solar optimisation features, which prioritise charging from solar over the grid. If you have a solar battery, your setup can be expanded to store daytime solar energy and use it for overnight EV charging.

Common Installation Challenges and How to Overcome Them

  1. Outdated Switchboards: Some older homes have switchboards that can’t handle the extra load of an EV charger. If yours is outdated, an electrician may need to upgrade it by adding a new circuit breaker or replacing the entire board. While this adds to the upfront cost, it’s a one-time upgrade that improves overall electrical safety in your home.
  2. Limited Meter Box Space: If your meter box is already full, there may not be room to add the dedicated circuit your charger needs. In this case, your electrician might install a sub-board or rearrange the layout to make space. 
  3. Long Cable Runs: If your charger needs to be installed far from the switchboard, like at the end of a long driveway, this can increase the cost and complexity. Longer cable runs may require heavier-duty wiring to maintain performance, so it’s a good idea to choose the most direct and practical location for the charger, if possible.
  4. Outdoor Mounting Issues: If you’re installing the charger outside, it must be weatherproof and mounted securely. Harsh sun, rain, and dust can damage unprotected units. Look for chargers with a high IP rating (e.g. IP65), and make sure your installer places it in a sheltered area or uses a weatherproof enclosure.
  5. Strata or Apartment Restrictions: If you live in an apartment or unit, you might need body corporate approval before installing an EV wall charger. Some buildings also have limited electrical capacity or shared infrastructure, so check with your strata manager before making any plans.

Planning ahead and working with a licensed electrician will help you spot these issues early and find the right workaround, so you can get charging faster with fewer surprises.

How to Maintain Your EV Wall Charger

Regular care will help your EV wall charger run smoothly and safely for longer. 

  1. Wipe the charger and cable regularly with a dry or slightly damp cloth to remove dust, dirt, and cobwebs. Avoid using harsh chemicals or high-pressure water. 
  2. Check the charger, plug, and cable for cracks, frayed wires, or signs of damage. If anything looks worn out or loose, stop using the charger and contact your installer or manufacturer for advice.
  3. Check that the cable plugs in and out smoothly and the charger feels secure on the wall. If the cable is difficult to connect or the unit feels loose, a minor adjustment or servicing may be needed.
  4. If your EV takes much longer to charge or the charger frequently stops mid-session, there may be an issue with the hardware or the connection to your switchboard. These are signs that servicing is required.
  5. If you notice unusual sounds, heat, or error messages, call a licensed electrician or the charger’s support team. It’s better to check it early than risk damaging your car or electrical system.
  6. Many smart chargers receive software updates that improve performance or add new features. Use the app (if available) to check for updates every few months. Staying up to date helps your charger run more efficiently and keeps it compatible with future EV models or energy systems.

How to Future-Proof Your EV Charging Setup

Look for an EV wall charger that supports various charging speeds and connector types, so it’ll still work if you upgrade to a different EV down the track. Some chargers can be adjusted or reconfigured as needed, so you won’t have to replace the whole unit when changing cars.

Smart chargers that receive firmware updates are another good choice. These updates improve performance, fix bugs, and sometimes add new features without needing a new device. Updates are usually managed through the charger’s app.

If you plan to add more electrical appliances to your home, such as an electric water heater or stovetop, choose an EV charger with dynamic load management. This feature automatically balances power use across your home, so the charger doesn’t overload your system.

Choosing Between an Inverter and Solar Inverter: A Homeowner’s Guide

About one in three Australian homes now have rooftop solar. Are you thinking of joining the club? If so, you’d be making a smart move! Solar energy is one of the most effective ways to cut your power bills.

You’ve likely done your research on solar panels, but what about inverters? This little box makes solar panels useful. No inverter? No power to your fridge, lights, or TV!

Not all inverters are the same. A regular inverter and a solar inverter have different jobs, and picking the wrong one could mean wasting energy—or worse—wasting money.

What are the differences between the two, how can you choose the right inverter, and why is Australian-owned iStore a name you can trust when it comes to powering your home with solar? Let’s find out!

What Is an Inverter?

A regular inverter is a device that converts direct current (DC) electricity from a battery, car, generator, or off-grid system into alternating current (AC).

Most household appliances run on AC power. So, if you have a battery or another source producing DC power, you’ll need an inverter to make that electricity usable in your home.

How Does an Inverter Work?

DC power flows in one direction, while AC power switches direction rapidly, which is the kind of electricity that comes through your power points. A regular inverter uses internal electronics to convert the one-way flow of DC into the back-and-forth flow of AC, so your home’s devices can run smoothly and safely.

In non-solar setups, you can use these inverters to

  • Power appliances during blackouts with stored battery power from backup systems.
  • Run devices from a car or portable batteries while camping, in a caravan, or on a boat.
  • Support off-grid living in remote homes or properties with generators or battery banks. 

What Is a Solar Inverter?

When solar panels collect sunlight, they produce electricity in the form of direct current. A solar inverter converts this DC electricity into AC electricity. Without a solar inverter, the energy from solar panels wouldn’t be compatible with appliances or the power grid.

How Does a Solar Inverter Work?

In a typical grid-tied residential solar system, a solar inverter constantly monitors how much electricity the home needs. It sends the converted AC power straight to appliances first. 

If your solar panels produce more energy than your home needs, the inverter routes that extra electricity back into the power grid. Your electricity provider usually gives you credits for the exported energy through a feed-in tariff.

A solar inverter can also work with solar batteries to store excess DC electricity generated during the day. When your home needs power at night or during cloudy weather, the inverter draws this energy from the batteries.

Solar Inverter Benefits for Your Home

Energy Efficiency

With a solar inverter converting solar energy into usable power for your home instantly, you can run your appliances during the day without relying on grid electricity. 

Any extra power your home doesn’t use is sent to the grid. If you have a solar battery, that excess energy can be stored for later, so you can keep using solar power at night or during cloudy weather instead of switching to grid power.

Some solar inverter models come with smart features that track your usage and adjust output to match your needs. That means less waste, lower power bills, and more control over how your home uses energy.

Cost Savings

Using solar energy allows you to rely less on electricity from the grid, which translates to lower electricity usage charges.

Your electricity provider may pay you through feed-in tariffs for any extra solar energy you don’t use and send back to the grid. Over time, these savings can add up and help offset the cost of your solar setup.

Sustainability

Choosing a solar inverter supports a more sustainable way of living and a cleaner energy future for Australia.

When you use solar energy, you reduce your reliance on electricity that comes from fossil fuels like coal and gas. The results? Fewer carbon emissions and a smaller impact on the environment.

In 2024, rooftop solar made up 12.4% of all solar electricity generated in the country, up from 11.2% in 2023. More and more households are contributing to Australia’s clean energy, and you can too!

Reliability

A solar inverter makes your home’s energy setup more reliable by keeping your power supply steady and managing how and when solar energy is used. 

In off-grid or hybrid setups with backup generators or battery storage, the inverter can automatically switch between solar, battery, and generator power. That way, your home stays powered even if the weather changes or there’s a grid outage.

Why Choose iStore for Your Inverter Needs?

Affordability

At iStore, we believe every Australian household should have access to solar power so they can cut their energy costs and reduce their environmental impact. That’s why we price our solar inverters competitively within the Australian market.

Safety

We know how important the safety of your home and family is. We’ve packed our solar inverters with the following safety features.

  1. AI-Powered Arc Fault Detection: Instead of relying on preset limits that may miss early warning signs, our inverters use artificial intelligence to monitor electrical patterns in real time. This detection system can recognise unusual activity that might lead to arcing and automatically shut down power to prevent damage or fire.
  2. Arc Fault Circuit Interrupter (AFCI): Identifies dangerous arc faults and cuts off power in under half a second, helping to eliminate potential fire hazards.
  3. Residual Current Monitoring Unit (RCMU): Constantly checks for stray electrical currents caused by moisture, insulation damage, or wiring faults. Any leakage triggers a safety response to avoid electric shocks, fires, or harm to your equipment.
  4. Natural Cooling Systems: Natural airflow and heat sinks (metal components that absorb heat and spread it out) regulate temperature and overheating. With no fans or moving parts, these systems cool quietly and minimise wear.

Durability

The best inverter for your home should have an IP (Ingress Protection) 65+ rating for weather protection, heat-resistant components, and robust build quality to withstand extreme temperatures, humidity, and dust.

​iStore single-phase solar inverters are rated IP65. They’re dust-tight, protected against water jets, and suitable for both indoor and outdoor installations. ​

Our three-phase inverter models are rated IP66, offering enhanced protection and durability in harsher outdoor environments.

User-Friendly Features

iStore solar inverters are easy for installers to install and customers to use.

What makes them so?

  1. Simple Installation and Setup: Clearly marked wiring points, flexible mounting options, and a straightforward interface help installers get the job done faster and reduce the chance of mistakes.

Factors to Consider When Choosing an Inverter

  1. Energy Needs: How much electricity does your household use daily? Check your last electricity bill. A larger home or one with high energy usage (pools, EV charging, or people working from home) may need a more powerful inverter.
  2. Efficiency: The higher the efficiency rating, the more solar energy is turned into usable power. Look for an inverter with 96% efficiency or higher to get the most out of your system.
  3. Compatibility: Make sure the inverter you choose works with your home’s grid connection (single or three-phase) and any future upgrades, like adding a solar battery or expanding your panel setup.
  4. Durability: Australian weather can be harsh, so check the inverter’s IP rating. An IP65 rating or higher means it’s protected against dust, rain, and heat and is suitable for outdoor installations.
  5. Cost vs. Benefits: While cheaper inverters might be appealing, investing in a quality inverter can save you more money in the long run through better performance, less maintenance, and longer warranties.

FAQs

What Is the Difference Between an Inverter and a Solar Inverter?

A regular inverter converts direct current (DC) electricity from a battery, car, generator, or off-grid system into alternating current (AC) that a home can use, while a solar inverter converts the DC electricity produced by solar panels into AC power.

Can You Use a Standard Inverter With Solar Panels?

A standard grid-tied inverter can be used with solar panels; however, it must be a solar-compatible inverter designed to work with a solar energy system. Regular inverters that aren't made for solar lack key features like Maximum Power Point Tracking, system monitoring, and grid export controls.
For safety, performance, and compliance with Australian standards, it's best to use a dedicated solar inverter or hybrid inverter with a solar panel setup.

Are Solar Inverters More Energy-Efficient Than Standard Inverters?

Yes. Solar inverters work specifically with solar panels and use smart features to maximise energy output. They convert more solar energy into usable power, making them more efficient than standard inverters in a solar setup.

How Long Do Solar Inverters Last?

Most solar inverters last between 10 and 15 years, depending on the type, quality, and local conditions. Some high-quality models can last up to 25 years with proper care and regular maintenance.

A home 3 phase EV charger changes the game. Fast, reliable, and ready when you are. 

iStore EV chargers are built for Aussie homes, priced to suit real budgets, and engineered for effortless charging.

Let’s explore how to choose the best home EV charger in Australia.

What is an EV Charger?

An EV charger is a device that uses electricity from your home’s power supply to charge the battery in your electric vehicle (EV) so you can drive it.

Why a Home EV Charger Is Essential for Australian EV Owners

Public charging stations are handy in a pinch, but they’re not always practical. Queues and slow charging speeds add up to wasted time. A home EV charger puts you back in control. Just plug in overnight and wake up to a full battery. 

This convenience is even more important in suburban and regional areas of Australia, where public chargers can be few and far between. With a home charger, you’re not relying on limited infrastructure or planning trips around charge stops. Your garage becomes your personal charging station.

Then there are the long-term savings. Charging at home is often cheaper than using public stations, especially if you plug in during off-peak hours when electricity demand is lower and rates are reduced, like late at night or early in the morning. 

Pair your EV charger with rooftop solar, and you can drive on sunshine, cutting your energy costs even further and reducing your carbon footprint!

EV Charger Types

Level 1 Chargers

Home EV chargers typically use alternating current (AC) to charge vehicles. 

Level 1 AC chargers that often come with an EV plug into a standard 230-volt (V) household outlet and typically deliver up to 2.4 kilowatts (kW) of power. 

They provide a driving range of around 8–15 km per hour of charging and can take up to 20 hours to fully charge a vehicle. This slower charging rate makes them suitable for overnight charging if you drive short distances daily.

Level 2 Chargers

Level 2 AC chargers require a dedicated 240 V circuit and professional installation. They add about 30–40 km of driving range per hour and can take 4–8 hours to charge an EV fully. This faster charging speed is ideal for longer daily commutes and households with multiple EVs. 

These chargers are available in single-phase (up to 7.4 kW) or three-phase (up to 22 kW). Most homes in Australia use single-phase power, which is fast enough for overnight charging. However, if your home has three-phase power—common in newer or larger properties—you can charge even faster.

Dumb vs Smart Chargers

“Dumb” EV chargers simply deliver power to your EV. They

  • Don’t have any smart features or app control.
  • Are easier to install and less expensive.
  • Charge at full power the moment they’re connected, regardless of electricity pricing or solar availability.
  • Are suitable for EV owners needing a basic charging solution.

Smart EV chargers do much more than just charge your EV. They

  • Optimise energy usage by adjusting charging times based on grid demand, solar availability, and your electricity tariff schedule.
  • Reduce electricity costs thanks to their energy efficiency. 
  • Connect to the internet to monitor charging in real-time, set schedules, track energy usage, and receive notifications through an app.
  • Are suitable for EV owners wanting cost-effective charging or using rooftop solar.

Key Features To Look For in the Best Home EV Charger in Australia

  1. Compatibility: The charger must be compatible with your EV’s plug type and charging capacity. 
  2. Charging Speed: Look for a charger that matches your daily driving needs. Most Level 2 chargers offer between 7.4 kW and 22 kW, which can significantly reduce charging times compared to a standard plug.
  3. Installation Requirements: Check if your home has single-phase or three-phase power. Some chargers also require a dedicated circuit or additional switchboard space, so confirm if any upgrades are needed before purchasing.
  4. Affordability: Weigh up the upfront cost of the charger with the long-term value. Features like smart charging, solar integration, or load balancing may cost more upfront but can save you money over time.
  5. Safety Features: Look for safety certifications, built-in protection against overvoltage or overheating, and weatherproof casing for outdoor installation. 
  6. Easy to Use: The best chargers are intuitive, with app control, clear indicator lights, and simple plug-in functionality. Wall-mounted units with cable holders also keep things tidy.
  7. Sustainability: If you have solar panels or plan to install them, choose a charger that supports solar optimisation. 

Apartment EV Charging and Body Corporate Considerations

Limited access to personal power supply, shared parking spaces, and a lack of installation space can make installing an EV charger in an apartment complex complicated. 

You’ll also likely need approval from your body corporate before any electrical work begins. This process may involve submitting detailed installation plans that show how costs and electricity usage will be managed, and ensuring there is no impact on other residents.

Longer summers. Rising energy prices. Bigger power bills. 

If you’re building or upgrading a house, solar energy should be at the forefront of your mind to combat these growing pressures.

But solar panels are only half the story. Solar batteries are fast becoming the must-have addition for households that want to store power, use more of their own energy, and reduce reliance on the grid.

Proudly Australian-owned, iStore offers high-performing, reliable, and competitively priced solar batteries for houses in our great country.

Why are solar batteries worth the investment, how do they benefit both builders and homeowners, and why is iStore’s range the ideal choice? We’ll discuss all that and more!

What Is a Solar Battery for a House?

Solar panels generate electricity during the day when the sun is shining. The home immediately uses the electricity it needs to power lights, appliances, and anything else running.

Around midday, when the sun is strongest, solar panels tend to generate more electricity than a household needs. Instead of sending that excess electricity back to the grid, a solar battery stores it.

This battery connects to a solar inverter, which turns solar energy into usable electricity.

Solar panels stop producing power once the sun goes down. At that time, the battery sends the stored energy into the home to keep everything running. If the battery runs low, the house will automatically draw power from the grid as a backup.

Why Solar Batteries Are Essential for Modern Houses

Power Backup

Think of a solar battery as a home’s personal energy reserve. Once the sun goes down, the battery steps in to keep lights on and appliances running.

In the event of a power outage, having backup energy from a solar battery gives peace of mind—no scrambling for candles or worrying about food spoiling!

Builders offering homes with battery backup show homeowners that they’re building with comfort, reliability, and modern living in mind.

Lower Electricity Bills

A solar battery stores the excess energy a home’s solar panels produce during the day so that the home can rely less on the grid and, in turn, pay less for electricity.

In peak hours (typically early mornings and evenings) when electricity rates are higher or on cloudy days when the panels aren’t generating enough energy, a home can use the stored energy from a solar battery instead of expensive grid electricity.

For homeowners, this means lower bills and more control over their energy use. For builders, it’s a great way to offer clients long-term savings and boost the value of a home.

Sustainability

Australian homes significantly contribute to the nation’s carbon emissions, accounting for over 10% of total emissions and around 24% of overall electricity consumption. This substantial reliance on fossil fuels, which release greenhouse gases, drives climate change.​

Integrating solar batteries into residential properties offers a practical solution to this issue. Enabling homeowners to utilise renewable energy even when the sun isn’t shining reduces dependence on fossil fuel-based electricity, leading to a direct decrease in household carbon emissions. 

Homeowners benefit by reducing their carbon footprint and participating in global efforts to combat climate change while enjoying the reliability and cost savings associated with renewable energy.​

Builders incorporating solar batteries into new constructions abide by sustainable building practices and enhance a property’s appeal to environmentally conscious buyers.

Choosing the Right Solar Battery for a House

What should you consider when choosing a solar battery for your home or a client’s?

  1. What size battery does the house need?

Check how much energy your household uses daily. You can find this on your electricity bill, usually in kilowatt-hours (kWh). 

For a home under construction, you’ll have to research how much electricity a home of similar size uses. As an example, the average Australian household of four uses about 22kWh a day. 

Choose a battery that can cover the household’s evening and overnight usage—typically around half their daily total. So, for 22kWh usage a day, a 10–15kWh solar battery would be suitable. 

  1. Is the battery compatible with the existing solar energy system setup?

If the home already has solar panels and an inverter, you must select a compatible solar battery.  

For systems with a standard string inverter, you may need to install a separate battery inverter to connect a battery. However, if the system already includes a hybrid inverter—which handles both solar and battery inputs—it’s much easier to add a battery.

  1. Are the battery’s materials durable and safe?

Choose a battery made from stable, long-lasting materials like lithium iron phosphate. These batteries are known for their safety, thermal stability, and long lifespan, which is especially necessary in Australia’s sometimes harsh climate.

  1. Can the battery system be scaled later?

If a home’s energy needs will increase over time, a modular battery system allows the addition of more battery units and storage without replacing the entire setup. This option is perfect for growing families.

  1. Is the price reasonable?

Look for value, not just the cheapest option. A good-quality solar battery may cost more upfront but will save users more in the long run with better performance and efficiency.

  1. Is the brand reputable?

Research brands with a proven track record, local support, and a solid warranty. A trusted name with good reviews and Australian-based customer service makes all the difference if you need help with the system down the line.

Installation and Maintenance of Solar Batteries for Houses

A professional, certified installer must install a solar battery system to ensure it meets all local building codes and safety regulations and to avoid potential legal and safety issues.​ Proper installation also maximises system performance and efficiency.​

Here’s how the installation process generally goes.

  1. Site Assessment: The installer evaluates the home’s current solar setup, electrical system, and space availability to determine the best location and compatibility for the battery. 
  2. System Design: They create a tailored plan, specifying the battery size, placement, and integration method with existing solar panels and the inverter.​
  3. Permits: They obtain the necessary permits to comply with local regulations and safety standards.
  4. Electrical Upgrades (If Needed): The home’s electrical panel may require upgrades to support the new battery system.
  5. Battery Mounting: The installer mounts the battery to a wall. Common installation spots are garages, undercover carports, or other areas protected from heat, moisture, and dust. 
  6. Electrical Integration: They then connect the battery to the solar inverter and install a safety disconnect, which is a switch that allows homeowners or technicians to quickly and safely shut off power to the solar battery for maintenance and emergency shutdowns.​ 
  7. System Configuration and Testing: The installer configures and tests the entire setup to make sure the battery charges and discharges correctly and everything functions safely. ​

Once the battery is installed, maintenance is vital to keep it running consistently and safely.

We’ve designed our solar batteries for minimal maintenance.

  • Weekly: Monitor the system’s performance through the iStore app, which works via the iStore WLAN dongle. Look for anything unusual, like lower-than-usual charge levels, the battery not discharging when expected, or error notifications.
  • Monthly: Check the battery for cracks, dents, corrosion on terminals, loose cables, and signs of water damage, especially if it’s installed outside.
  • Every 1–2 Years (Or As Needed): Arrange a professional service every year or two. Contact a certified technician immediately to address any irregularities or issues.​

FAQs

What Is the Best Solar Battery for a House?

The best solar battery for a house is one that matches the household’s energy needs, works with the house’s existing solar setup, and offers reliable performance, safety, and long-term value.

You know a solar inverter is the key player in converting solar energy into usable power. If it’s unreliable or inefficient, the entire system suffers, leading to unhappy customers, warranty headaches, and costly callbacks!


That’s why choosing the right inverter is not just about specs but also about safety, reliability, and long-term value.

At iStore, we understand this. Our solar inverters are built for peace of mind, performance, and affordability, making them a top choice for retailers and installers looking to offer products that deliver real results.

What is the best solar inverter to recommend to your customers? Let’s break down the features that make an inverter truly “the best”.

Definition and Function of Solar Inverters

A solar inverter converts the DC electricity generated from solar panels into the AC electricity homes and businesses use. Various inverter types are available to suit different system sizes, energy needs, and installation setups.  These include String inverters Microinverters Hybrid inverters Central inverters 3-phase inverters We’ll go into detail about these later on.

How Solar Inverters Work

You know how a solar inverter works, but explaining that to customers can be challenging! 

Try this:

“A solar inverter is like a translator for your solar power system. Imagine you’re travelling to Japan. You understand English (DC electricity), but the locals only speak Japanese (AC electricity). To communicate with a local, you need a translator (the inverter) to convert your English into Japanese.
Solar panels absorb sunlight and generate DC electricity. Homes and businesses run on AC electricity. Without an inverter, solar power is not compatible with appliances, lighting, or the grid.”

Here’s a more technical explanation if they’re interested.

  1. Solar Panels Capture Sunlight: When the sun shines on solar panels, the photovoltaic (PV) cells absorb the sunlight, exciting electrons and generating direct current (DC) electricity. 
  2. The Inverter Receives DC Power: The raw DC electricity from the panels can’t be used directly in most homes or businesses, which run on alternating current (AC) electricity. The solar inverter receives this DC power and prepares it for conversion.
  3. MPPT Technology Optimises Energy Production: The inverter uses Maximum Power Point Tracking (MPPT) technology to adjust the panels in changing sunlight conditions (shade, cloud cover, and temperature changes) to extract the maximum possible energy.
  4. DC Power Converts to AC Power: Inside the inverter, the DC electricity switches rapidly back and forth, creating an alternating current (AC) waveform that matches the electricity used in homes and businesses. 
  5. Grid Synchronisation and Safety Features Activate: If the system connects to the electricity grid, the inverter synchronises the converted AC power with the grid’s voltage and frequency. Anti-islanding protection automatically shuts off power if the grid goes down, preventing unsafe backfeeding into power lines during outages.
  6. Power is Used or Sent to the Grid/Battery: The converted AC power flows into the home or business, powering appliances, lighting, and other electrical devices. Excess energy can be exported to the grid for credits (if grid-tied) or stored in a battery for later use (if part of a hybrid or off-grid system).

Importance of Solar Inverters for Solar Panels

A solar inverter 

  • Converts Energy for Use. The inverter transforms raw DC power from solar panels into functional AC power for everyday use.
  • Optimises Solar System Efficiency. A high-quality inverter maximises power output, improving energy efficiency and system performance.
  • Monitors System Performance. Many modern inverters have monitoring features that track energy production, efficiency, and potential system issues.
  • Enables Grid Connection. If a system connects to the grid, the inverter ensures that the electricity matches grid standards for seamless integration.
  • Supports Battery Storage. In hybrid systems, inverters manage energy flow between solar panels, batteries, and the grid.

What Makes a Solar Inverter the Best? Key Features to Look For

Safety

A solar inverter should protect the solar power system, the home or business, and the people who depend on its electricity. Safety features prevent electrical hazards, extend the inverter’s lifespan, and comply with Australian electrical and grid standards. 

The best solar inverter should have the following safety features. 

  • Arc Fault Protection: Detects and stops dangerous electrical arcs caused by faulty wiring, aging components, and loose connections, reducing the risk of fires.
  • Cooling Systems: Heat sinks (metal components that absorb and dissipate heat) and passive cooling (which relies on natural airflow) prevent inverters from overheating and failing. 
  • Surge Protection: Absorbs sudden voltage spikes caused by lightning or grid fluctuations, shielding the inverter from damage.
  • Anti-Islanding Protection: Prevents the solar system from sending power back to the grid during a blackout, protecting utility workers and complying with regulations.
  • Ground Fault Detection: Monitors the electrical circuit for leaks (where electricity unintentionally flows to the ground) and automatically shuts down the system to prevent electric shocks and fires.
  • Rapid Shutdown Function: Quickly shuts down the system in an emergency, protecting installers and emergency responders from electrical hazards.

Reliability

A reliable solar inverter will produce consistent energy for many years, be less likely to break down, and be cheaper to maintain.

For an inverter to be considered reliable, it must have

  • High-Efficiency Ratings. These translate to maximum energy conversion, reduced losses, and the delivery of more usable power from solar panels.
  • Proven Durability. A quality inverter should have an IP65+ rating for weather protection, heat-resistant components, and robust build quality to withstand extreme temperatures, humidity, and dust.
  • Consistent Grid Stability. To smoothly manage voltage fluctuations, grid instability, and load changes for stable operation, even during peak demand periods.
  • A Long Warranty. A strong manufacturer-backed warranty of at least 10 years reflects confidence in the product’s longevity.
  • Comprehensive Customer Support. Local technical support and service availability for warranty claims, installation queries, and performance issues mean installers and customers get fast, effective solutions when needed.
  • A Proven Track Record. Trusted brands will have a history of positive user feedback.

Affordability and Value

When recommending an inverter, balance upfront cost with performance and durability so your customers get the best return on their investment. A well-priced inverter that performs dependably for years is a far better investment than a budget option that fails prematurely or needs frequent servicing! 

Here’s what to consider when evaluating affordability and value.

  • Cost vs. Performance: While a lower-cost inverter may save money upfront, it could lead to higher maintenance costs or early replacement. Investing in a reliable, efficient model often yields greater savings over time.
  • Warranty Coverage: A longer, manufacturer-backed warranty adds value by protecting against costly repairs or replacements.
  • Efficiency and Energy Savings: A high-efficiency inverter converts more solar energy into usable electricity, reducing waste and maximising energy bill savings.
  • Built-in Features: Some inverters come with advanced monitoring, surge protection, and battery compatibility, which provide added benefits without extra costs.
  • Rebates and Incentives: Certain reputable inverters may be eligible for government rebates or incentives, making them more affordable.

Compatibility

A solar inverter must integrate with the rest of the solar power system for optimal performance. Choosing the wrong inverter can lead to inefficiencies, limited functionality, and even system failures.

An inverter should work well with

  • Solar Panel Capacity and Voltage Range. The inverter must match the solar panels’ total power output and voltage to avoid energy losses and system inefficiencies.
  • Battery Storage Systems. If the system includes (or may later include) a solar battery, a hybrid inverter will smoothly manage energy between solar panels, batteries, and the grid.
  • Grid Requirements and Regulations. A compliant inverter must meet Australian grid standards, including voltage, frequency, and safety requirements for seamless grid connection and feed-in tariff eligibility.
  • Monitoring and Smart Features. Many inverters integrate with Wi-Fi monitoring platforms, allowing customers and installers to track performance, detect issues, and optimise energy use.
  • Backup Power and Off-Grid Systems. Some inverters can support off-grid or backup power functionality to keep essential appliances running during power outages.

Ease of Use and Monitoring

The best inverters should be easy for installers to install and easy for customers to operate. That way, everybody wins!

What makes an inverter easy to use and monitor?

  • Simple Installation and Setup: Clear wiring terminals, straightforward mounting options, and an intuitive interface make the installation process quicker and reduce the risk of errors.
  • Real-Time Energy Monitoring: Wi-Fi or Bluetooth connectivity lets users track energy production, consumption, and system health via a mobile app or web portal.
  • Automated Alerts and Diagnostics: Smart inverters can detect faults, send automatic alerts, and give troubleshooting insights, helping installers and users resolve issues quickly before they impact performance.
  • User-Friendly Display: Customers can check their system’s status at a glance on a built-in LCD or LED screen displaying performance metrics.
  • Remote Access and Smart Integration: Some advanced inverters integrate with smart home systems, battery storage, and third-party monitoring platforms, giving users more control over their energy usage.

Comparing Solar Inverter Types: Which Is Best for Your Customers?

String Inverters

A string inverter is the most common type of solar inverter used in residential and small commercial solar systems. It connects multiple solar panels in a series (or “string”), converting the combined DC electricity from all the panels into usable AC power for a home or business.

Pros

Cost-Effective: More affordable than microinverters or hybrid systems.
Proven Technology: Widely used and trusted in the solar industry.
Easier Installation and Maintenance: Since there’s only one inverter, servicing is simpler than troubleshooting multiple microinverters.
Good for Unshaded Roofs: Works efficiently when all panels receive consistent sunlight throughout the day.

Cons

Performance Dependency: Since all panels in a string are connected to one inverter, their performance is linked. If one panel is shaded, dirty, or underperforming, it reduces the efficiency of the entire string.

Limited Design Flexibility: Panels must be installed at the same angle and orientation for best performance.
No Panel-Level Monitoring: Unlike microinverters, string inverters don’t allow for individual panel performance tracking.  

Microinverters

Unlike string inverters, which manage multiple solar panels at once, microinverters are installed on each individual panel. This means every panel operates independently, converting its own DC electricity into AC power right at the source.

Pros

Maximised Energy Production: Each panel performs independently, so shading or dirt on one panel doesn’t reduce the output of the others.
Greater Design Flexibility: Panels can be installed at different angles and orientations on complex roof layouts or areas with partial shading without impacting system performance.
Panel-Level Monitoring: Users can track individual panel performance, making detecting and fixing issues easier.
Increased Safety: Converts DC to AC at the panel level, reducing the risk of high-voltage DC hazards.

Cons

Higher Cost: More expensive upfront than string inverters due to needing multiple units.
More Complex Installation: Each panel requires its own inverter, increasing installation time.
Difficult Maintenance: If a microinverter fails, troubleshooting and repairs may be more time-consuming since each inverter is mounted on the roof.

Hybrid Inverters

A hybrid inverter does everything a standard solar inverter does—converting DC electricity from solar panels into AC power—but with one big advantage: it can also manage battery storage. Homeowners or business owners can store excess solar energy in a battery instead of sending it to the grid.

Pros

Battery-Ready: Easily integrates with solar batteries for energy storage and backup power.
Greater Energy Independence: Reduces reliance on the grid by storing excess solar power for later use, like at night or during blackouts

Optimised Energy Management: Smart software helps manage energy flow between solar panels, batteries, and the grid for maximum efficiency.
Future-Proof Investment: Allows for easy upgrades later if a battery isn’t installed right away.

Cons

Higher Upfront Cost: More expensive than traditional string inverters due to added battery management features.
System Configuration Required: While hybrid inverters are battery-ready, they can require custom settings and programming from a professional installer. 

May Require a Compatible Battery: Some hybrid inverters only work with specific battery brands or types, limiting flexibility.

Central Inverters

Central inverters work similarly to string inverters but on a much larger scale. Instead of handling a few solar panels, they manage power from hundreds or even thousands of panels simultaneously. These inverters are typically used in large commercial and utility-scale solar farms, where multiple panel strings feed into a single, high-capacity inverter.

Pros

High Efficiency for Large Systems: Optimised for processing energy from hundreds or thousands of solar panels.
Lower Cost Per kW: More economical for large installations compared to using multiple smaller inverters.
Simplified Maintenance: With a single, centralised unit, servicing and troubleshooting can be more straightforward than maintaining many smaller inverters.

<Cons

Performance Dependency: Since many panels feed into one unit, an issue in part of the system can reduce overall efficiency.
Higher Risk of Downtime: If the central inverter fails, the entire system stops producing power until repairs are made.

3-Phase Inverters

A 3-phase inverter is designed for properties with a 3-phase power supply, such as large homes, businesses, and industrial sites. Unlike standard single-phase inverters that send power through one electrical phase, 3-phase inverters distribute electricity evenly across three phases, making them ideal for handling higher energy loads.

Pros

Ideal for High Power Demand: Supports larger properties with high energy needs, a 3-phase power supply, and inverter capacities exceeding 5kW.

More Efficient Power Distribution: Spreads energy evenly across three phases, reducing voltage fluctuations and improving stability.
Better Grid Compatibility: Works perfectly with 3-phase electrical systems, preventing overloads and improving performance.
Supports Larger Solar Arrays: Can handle higher solar panel capacities for large installations.

Cons

Higher Upfront Cost: More expensive than single-phase inverters due to their increased capacity and advanced functionality.
May Require Grid Approval: Some locations have specific regulations for connecting 3-phase inverters to the power grid.

What is a Solar Inverter and How Does It Work?

A solar inverter takes the energy solar panels collect from the sun and turns it into electricity you can use at home. 

  1. Solar Panels Capture Sunlight. The solar panels installed on your roof or on ground-mounted frames soak up sunlight and convert it into DC electricity (direct current). But there’s a slight problem—your home appliances can’t use this electricity!
  2. The Inverter Steps In. The solar inverter takes that DC electricity and converts it into AC electricity (alternating current), which is the type of power your home runs on. It does this by rapidly switching the direction of the current using electronic circuits and components like transistors and capacitors. This process mimics the natural oscillation of AC power, making it compatible with your home’s electrical system. Your solar inverter will be installed near the main switchboard of your home, either on a shaded and well-ventilated exterior wall or inside a garage to protect it from extreme weather. 
  3. Electricity Flows to Your Home. Once converted, the AC electricity flows to your power outlets for lights, appliances, and anything else that needs power.
  4. Extra Energy Is Redirected or Stored. If your solar panels produce more energy than your home uses, the extra electricity can either go back into the grid, which may earn you credits on your power bill (depending on your energy provider), or be stored in a solar battery (if you have one), so you can use it later when the sun isn’t shining.
  5. The Inverter Monitors Solar Output. A good solar inverter should also monitor how much electricity your panels generate and how much your home consumes using built-in sensors and software. This data is usually accessible via a display screen or a mobile app.
  6. The Inverter Keeps the Solar System Running Safely. If there’s a fault—like an electrical surge, overheating, or a wiring issue—the inverter has protective circuits that detect the problem and automatically shut down the system.

Types of Solar Inverters

String Inverters

A string inverter is the most common type of solar inverter used in home solar systems. It connects multiple solar panels in a series (or “string”), meaning all panels feed their electricity into a single inverter.

Since all panels connect in a single string, performance depends on the weakest panel. If one panel is shaded or dirty, it can reduce the output of the entire string. So string inverters are ideal for homes and small to medium-sized businesses with uniform conditions: consistent sun exposure and simple roof layouts. 

What makes string inverters unique?

  • Centralised Conversion: Instead of each panel having its own inverter, all the panels in a string send DC electricity to one central inverter for conversion.
  • Cost-Effectiveness: Since there’s only one inverter for the entire system, string inverters are generally more affordable than other inverter types.
  • Simple Installation and Maintenance: With fewer components, these inverters are easier to install and maintain.

Microinverters

A microinverter is a small inverter installed on the back of each solar panel instead of having one central inverter for the whole system. Each panel operates independently, converting DC electricity to AC directly at each panel.

Microinverters are ideal for homes and businesses with shading issues, as unaffected panels can continue operating at full capacity even if trees or nearby buildings shade other panels. They also work well for complex roof designs where panels face different directions or receive partial shading at various times of the day.

What makes microinverters unique?

  • Panel-Level Optimisation: They maximise energy output from each panel, so shading or panel mismatches don’t reduce power.
  • Improved Monitoring: Many microinverters feature panel-level monitoring so you can track the performance of each panel to detect issues, keep the system running efficiently, and prevent energy loss.
  • Longer Lifespan: These inverters typically last longer than string inverters, often matching the 25-year lifespan of solar panels.

Power Optimisers

A power optimiser is a small device installed on the back of each solar panel that optimises the DC electricity before sending it to a central string inverter for conversion into AC power. Unlike microinverters, power optimisers do not convert DC to AC at the panel level. 

Power optimisers are best for residential and commercial solar systems that use string inverters and need improved performance for panels installed in partially shaded areas or at different angles. 

What makes power optimisers unique?

  • Works with a String Inverter: Unlike microinverters, power optimisers don’t replace the main inverter but enhance its performance by improving DC output before conversion.
  • More Affordable: Since conversion still happens at a central inverter, power optimisers cost less than installing individual microinverters on each panel.
  • Better Monitoring and Fault Detection: Individual panel monitoring and quick troubleshooting are possible, but complete data access requires a compatible inverter.

Hybrid Inverters

A hybrid solar inverter does the work of a standard string inverter with the bonus of managing battery storage. Instead of sending excess solar energy to the grid, a hybrid inverter can store that energy in a battery for later use when the sun isn’t shining, reducing reliance on the grid and providing backup power during blackouts.

Hybrid inverters are ideal in areas with unstable grid supplies and for households wanting to maximise their solar energy usage. While they cost more upfront than standard inverters, they offer greater solar power flexibility and long-term electricity savings.

What makes hybrid inverters unique?

  • Built-in Battery Management: Controls both solar energy and battery storage in one system.
  • Smart Energy Use: Automatically switches between solar, battery, and grid power based on demand.
  • Future Scalability: You can start with a basic solar system and add a battery later, making it easy to upgrade as your energy needs change.

3-Phase Inverters

A 3-phase inverter connects to a 3-phase power supply. Unlike standard single-phase inverters, which send all solar energy through one power line, a 3-phase inverter evenly distributes electricity across three power lines.

3-phase inverters are ideal for larger homes, commercial buildings, and industrial facilities that require higher power loads due to many occupants, heavy machinery, large air conditioning systems, and other high-energy equipment.

What makes 3-phase inverters unique?

  • Even Power Distribution: Provides a more balanced and efficient energy flow and reduces the risk of power drops when multiple high-energy appliances run simultaneously.
  • Grid Stability: Helps maintain a more stable voltage, reducing strain on the electricity grid and minimising the risk of overvoltage issues that can occur with high solar output.

Why Safety and Reliability Are Critical in Solar Inverters

A solar inverter constantly converts energy, manages power flow, and handles high-voltage electricity. If your inverter is not well-protected and reliable, your system could experience performance issues, electrical faults, and safety risks.

Look for the following safety features in advanced, top-of-the-range inverters.

  • Arc Fault Circuit Interrupter (AFCI): Detects and shuts down dangerous electrical arcs, which can cause fires due to faulty wiring, aging components, or loose connections. 
  • Natural Cooling Systems: Overheating is a major cause of inverter failures. High-quality inverters use heat sinks—metal components that absorb and dissipate heat without fans or moving parts—and passive cooling, which relies on natural airflow. This design reduces operating noise and system wear. 
  • Surge Protection: Shields the inverter from sudden voltage spikes caused by lightning strikes or grid fluctuations.
  • Ground Fault Detection: Identifies leaks in the electrical circuit and shuts the system down to prevent electric shocks or fires.
  • IP-Rated Enclosures: A weatherproof casing rated IP65 or higher protects the system from dust, rain, and extreme temperatures to extend its lifespan. 

Choosing the Right Solar Inverter for Your Solar Panel System

Picking the right solar inverter is just as important as choosing your solar panels. The inverter controls how efficiently your system runs, how long it lasts, and how well it integrates with your home’s power needs. 

Here’s what to consider.

1. Compatibility

Choose an inverter that matches your solar panel capacity to avoid energy loss.

If you plan to add battery storage, choose a hybrid inverter to handle both solar and battery power. 

If your home uses 3-phase power, choose a 3-phase inverter for even energy distribution, provided it meets local grid regulations. 

2. Performance

Consider efficiency ratings. Higher efficiency means less energy wasted during conversion.

If your roof has shading or different panel orientations, microinverters or power optimisers can prevent one shaded panel from reducing the entire system’s output.

3. Safety

Make sure that the inverter has safety features like an AFCI (Arc-Fault Circuit Interrupter), surge protection, and ground fault detection.

4. Durability

Look for an inverter with strong weather protection (IP65 or higher) if it will be installed outdoors.

Also, look for passive cooling systems (with heat sinks instead of fans), as these tend to last longer and operate quietly.

Check the warranty. A quality inverter should have at least a 5-year warranty.

5. The Advice of a Reputable Solar Company

The best way to find the right inverter for your needs is to speak with a trusted solar provider. 

Ask them:

  • What type of inverter is best for my home and energy usage?
  • Does this inverter work with battery storage if I want to add one later?
  • What safety features does it have?
  • What warranty and support options are available?

A provider that knows their stuff—like iStore!—will be able to answer these questions and guide you to the right inverter.
