More Aussie drivers are ditching the detours to public charging stations and installing EV chargers at home for convenience, cost savings, and more eco-friendly driving.

After choosing the best EV charger for your home and vehicle, the next logical question is, “How do you install an EV charger at home?” Can you DIY, or do you need professional help?

We’re here to explain what’s involved in installing an EV charger at home, from how much it costs to the installation process, whether DIY or professional.

Why Install an EV Charger at Home?

• Greater Convenience: Charge while you’re at home during the day or sleeping at night. No need to drive out of your way or queue at public stations.
• Lower Charging Costs: Home charging is usually cheaper than public stations, especially if you set your charger to run during off-peak times. Energy providers offer discounted rates when electricity demand is lower, typically late at night or early in the morning. 
• Better Energy Efficiency: Pairing your charger with solar panels, an inverter, and a battery lets you use clean, renewable energy to power your EV, cutting carbon emissions and energy bills.
• Future Flexibility: Having a charger at home means you’re ready to upgrade to a newer EV model, switch brands, or add a second EV. Most home chargers support a wide range of EVs, so you won’t need to reinstall new equipment whenever you change cars.
• Higher Property Value: Homes with EV chargers are becoming more desirable as more people switch to using EVs. 

Types of Home EV Chargers

Level 1 Chargers

Your EV should come with a free Level 1 charger that plugs into a standard residential 230–240V power outlet. 

With a power output of around 2.4 kW, they’re the slowest EV charger, taking 12–20+ hours to fully charge most EVs. You can expect to add 10–15 km of range to your EV per hour of charging.

Because of their slower charging speed, Level 1 chargers are a good option if you don’t drive much or only need to top up occasionally.

Most Level 1 chargers don’t offer smart features like app control or charging schedules. They also aren’t usually compatible with solar systems; instead, they draw power from the electricity grid.

Level 2 Chargers

Level 2 EV chargers use a dedicated 230–240V circuit with higher amperage to deliver more power to your car in less time than a standard power point. An electrician will wire the charger directly into your switchboard.

Most homes run on single-phase electricity, which supports Level 2 chargers with an output of around 7.2 kW. These chargers can add 30–50 km of range per hour and fully charge an EV in 4–10 hours. Larger or rural properties with three-phase power can support chargers up to 22 kW, which add up to 120 km of range per hour and deliver a full charge in just 1.5–4 hours.

You can buy a Level 2 charger from your car dealer, EV charger retailers, or online stores. They’re ideal for daily use, longer commutes, and multi-EV households. 

Smart Chargers

Many Level 2 chargers include smart features such as 

• App Control: Start or stop EV charging, check charging status, and get notifications through a mobile app.
• Charging Scheduling: Set the charger to run at specific times, like during off-peak hours when electricity is cheaper. 
• Energy Monitoring: Track how much energy your EV uses and view your charging history to give you better insight into running costs and power usage.
• Load Management: Automatically balances the charger’s power use with the rest of your household to prevent overloading your electrical system. 
• Solar Integration: Use excess solar power to charge your EV instead of drawing from the grid. Some chargers can prioritise solar usage or mix solar and grid power for maximum efficiency.

Key Requirements for Installing an EV Charger at Home

Before you install an EV charger at home, there are some important things to consider.

The power your home has affects what kind of charger you can install and how quickly your EV can charge.

Most homes in Australia use single-phase power, which can handle a basic Level 1 charger or a Level 2 charger with an output of around 7.2 kW for faster, overnight charging. Larger homes or rural properties with three-phase power can support faster chargers up to 22 kW. 

If you choose a Level 2 charger, it will need a dedicated circuit so it doesn’t compete with other appliances in your home. An electrician will assess your switchboard to make sure it has enough capacity and upgrade it if needed.

Lastly, think about where you’ll install the charger. It should be near where you park your EV and within reach of the charging cable. The spot should also be easy to access, protected from the weather, and safe from potential damage. Wall-mounted units in garages or under carports are common, but outdoor setups can work too, as long as the charger is weatherproof and professionally installed.

Step-by-Step Guide to Installing an EV Charger at Home

Level 1 Charger

Installing a Level 1 EV charger is a DIY job.

1. Your EV should come with a Level 1 charger. Take it out of the boot or storage compartment.
2. Find a power point close to where you park your EV. A garage or undercover carport works best.
3. Plug the charger into the power point. No special tools or installation are needed.
4. To keep things tidy, you can mount the charger on a wall using a bracket or hook. If a bracket/hook isn’t included, you can buy one from Bunnings or an online EV accessories store.
5. Plug the charger into your EV. Check your EV’s dashboard or app to track charging progress.

Level 2 Charger

Installing a Level 2 charger is more difficult and must be done by a licensed electrician. High-voltage wiring and compliance with electrical safety regulations are involved.

Your electrician will

1. Assess the switchboard and wiring. They’ll inspect your switchboard to confirm it can handle the charger’s load, checking your wiring, power type (single or three-phase), and space for a new circuit breaker. Your switchboard may need an upgrade.
2. Run a dedicated circuit. Because EV chargers need their own circuit, the electrician will install new cabling from your switchboard directly to the charger’s location. They’ll plan a safe, efficient cable path that avoids other wiring or plumbing.
3. Install a safety switch. It is a legal requirement to install an RCD (residual current device). This safety switch reduces the risk of electric shock and faults.
4. Mount the charger. Once the wiring is complete, the electrician will mount the charger on a sturdy wall or surface using a bracket or mounting kit. They’ll discuss the location with you: somewhere protected from the elements, easy to access, and near where you park your EV.
5. Connect the charger and test the system. The electrician will wire the charger into your power supply, test that everything works correctly, and check that the installation meets Australian standards (AS/NZS 3000). They’ll provide a Certificate of Compliance to confirm they did the job safely and legally.
6. Set up any smart features. If your charger has an app or smart control system, the electrician can connect it to your Wi-Fi and guide you through features like remote charging, scheduling, and monitoring.
7. Configure solar charging (if applicable). If your home has solar panels, the electrician can link the charger to your solar system so it prioritises solar energy when available. If you also have a solar battery, they can configure your system to store daytime solar energy and use it for overnight charging.

DIY vs. Professional Installation

While installing a Level 2 charger yourself might be tempting to save money, it’s not a safe or legal option. 

These chargers draw much more power than a standard appliance and must be wired directly into your switchboard. Handling high-voltage electrical work without a licence can lead to safety risks, fire hazards, and insurance issues. 

DIY installation doesn’t comply with Australian electrical standards, which could void your EV charger’s warranty or create problems when selling your home.

Hire a licensed electrician to get the job done safely and correctly. They’ll make sure your switchboard can handle the charger, install the correct safety switches, and provide a Certificate of Compliance to protect your warranty and give you peace of mind.

Costs of Installing a Home EV Charger

How much does it cost to install an EV charger at home? 

The answer varies depending on the charger, installation complexity, electrical upgrades, and solar integration.

As discussed, a Level 2 EV charger requires professional installation. Including labour and materials, basic installation can cost $700–$1,300. The chargers themselves can range from $500 to $2,000. So you can expect to pay a total of $1,200–$3,300.

If your switchboard is older or undersized, you could pay $900–$1,800 for a single-phase upgrade or $1,500–$3,500 for a three-phase upgrade.

If you want to integrate the charger with your solar system, there may be additional costs for solar-compatible chargers, components, and system configuration. Your electrician may charge a flat rate or by the hour for solar integration. The hourly rate could range from $80 to $130, depending on location and job complexity. 

EV Charger Incentives in Australia

Some state and territory governments offer incentives for installing an EV charger at home.

In the Northern Territory, the EV Charger Grants Scheme offers $1,000 to EV owners for purchasing and installing a home charger. Over in the ACT, eligible homeowners can get a zero-interest $2,000–$15,000 loan to buy an EV charger.

There are also federal and state incentives for installing solar batteries, which can make solar EV charging more affordable.

Starting July 1, 2025, the federal Cheaper Home Batteries Program offers up to a 30% reduction in the cost of home solar batteries.

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 with existing solar.

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.

Solar is fantastic…until the sun goes down! That’s where a solar battery comes in. 

If you already have a solar battery, you may be wondering when it’s time for a new one. Or perhaps you’re investigating going solar and all that involves. Before you buy a solar battery, there is an important question to answer: how long do solar batteries last?

Investing in a solar battery means investing in years of energy storage, so it’s worth knowing what you’re getting for your money. 

Let’s unpack how long solar batteries last, what wears them out, and how to stretch every dollar of value from your battery.

What Is a Solar Battery?

Solar panels can generate more electricity than your home uses in a day. Instead of returning unused solar energy to the grid, a solar battery stores it for later use when the sun isn’t shining, like at night or on cloudy days. It can also kick in during blackouts or when energy prices spike, keeping the lights on and costs down.

A solar battery gives you more control over your power usage, reduces your home’s reliance on the grid, and saves you money on electricity bills.

What Is the Average Lifespan of Solar Batteries?

Most solar batteries last between five and 15 years.

The exact lifespan of a battery depends on several key factors. 

Factors That Affect Solar Battery Lifespan

Battery Type

Lithium-ion solar batteries are the most common option used in Australian homes. They tend to last longer, often around 10 to 15 years. They’re more efficient, hold charge better, and cope well with daily use without wearing out too quickly.

Lead-acid batteries are an older style. They’re cheaper upfront, but usually only last three to seven years. They also need more maintenance and don’t handle frequent charging and discharging as well as lithium-ion batteries.

Depth of Discharge (DoD)

Depth of Discharge (DoD) refers to how much of your battery’s stored energy your home uses before the battery starts recharging from your solar panels. For example, if a battery has a 90% DoD, you can use up to 90% of its stored energy before it starts recharging.

Regularly using a large portion of stored energy or draining the battery close to empty puts extra strain on it. That wear and tear adds up and can shorten the battery’s lifespan.

Choosing a battery with a high recommended DoD, like many lithium-ion models, helps you get more usable energy and life from it.

Usage Patterns

How often your solar battery charges and discharges (fills up with energy and then powers your home) each day plays a big role in how long it lasts. Each full round of charging and discharging is called a cycle.

Most batteries can handle thousands of these cycles, but heavy daily use can wear them out faster. If your system is set up so the battery constantly charges during the day and almost entirely drains at night, it will age quicker than one used more gently.

The fewer full cycles your battery goes through each day, the longer it’s likely to last. That’s why having the right-sized system for your energy needs can make a real difference over time.

Temperature and Climate

Solar batteries don’t like extreme heat or cold. High temperatures can age a battery faster and reduce how much charge it can hold, while freezing weather can slow performance and efficiency.

Most systems work best in mild, stable conditions. You should install your battery in a spot protected from harsh weather, like a garage, under a shade, or in a weatherproof cabinet.

Maintenance

Regular inspections and proper maintenance of a solar battery can identify minor issues before they become big problems. Check for dust, corrosion, or any warning lights on the system. 

Some batteries are low-maintenance, especially lithium-ion types, but it’s still worth giving them a quick check every so often and booking a professional service yearly.

How to Maximise the Lifespan of Solar Batteries

1. Avoid Overcharging/Deep Discharging: Use built-in battery protection settings or a battery management system (BMS), a tool that controls how your battery charges and discharges. These systems help prevent overcharging or draining the battery too low.
2. Choose a Battery Compatible With Your Solar Inverter: Your solar battery must be compatible with your system’s solar inverter. A mismatch can lead to inefficient charging and unnecessary strain on the battery.
3. Control the Temperature: Install your battery in a shaded, well-ventilated outdoor area or indoors if possible. Avoid places with extreme heat or cold, as temperature swings can damage the battery.
4. Keep Up With Regular Maintenance: Check for dust, loose wires, corrosion, and system alerts every few months. Book a yearly inspection with a solar technician to keep everything in good shape.
5. Use Smart Monitoring Tools: Devices like iStore’s WLAN dongle let you track battery performance, usage, and health in real time, so you can catch issues early and manage your energy more efficiently.

When Should You Replace a Solar Battery?

Even the best solar batteries wear out. Look out for these signs that it might be time for a replacement.

• Shorter Backup Time: If your battery doesn’t power your home as long as it used to, it may be losing capacity.
• Slower Charging: If the battery takes much longer to charge fully, that’s a red flag.
• Unusual Noises and Overheating: Strange sounds and excessive heat can mean something’s wrong internally.
• Warning Lights or Error Messages: Your system may alert you when the battery isn’t performing properly.
• Battery Age: If your battery is 10–15 years old, it could simply be reaching the end of its natural lifespan, even if it’s still working.

How Much Do Solar Panel Batteries Cost?

Many factors influence the cost of replacing a solar battery.

• Size: Bigger batteries (measured in kWh) cost more. 
• Type: Lithium-ion batteries last longer and perform better, but cost more than older lead-acid models. 
• Brand: Well-known brands come at a premium.
• Installation Complexity: Replacing or adding a battery to an existing system may require extra parts or electrical work, which adds to the cost.
• Your Location: Labour and transport costs vary. Remote or regional areas may face higher charges than metro areas.
• Extra Features: Batteries with blackout protection, smart home integration, or advanced monitoring tools usually cost more.
• Government Rebates: From July 2025, the Australian Government’s Cheaper Home Batteries Program will offer a 30% discount on eligible home batteries. Extra rebates may apply in some states.

Replacing a solar battery can generally cost between $8,000 and $14,000. For example, installing a 5 kWh battery can cost around $8,700, while installing a 15 kWh battery can cost approximately $13,550.

Why Choose iStore Solar Batteries?

Durability: Tough Tech, Built to Last

iStore solar batteries can easily handle Australia’s tough and varied climate, operating reliably in temperatures from -20°C to 55°C.

They use lithium iron phosphate (LiFePO₄) technology, which is known for its stability, safety, and long lifespan. This type of battery chemistry resists overheating, supports thousands of charge cycles, and degrades more slowly, making it one of the most durable options on the market.

Safety: Self-Protecting for a Safer Home

Our lithium iron phosphate batteries have four layers of built-in protection.

1. Stable Battery Chemistry: Lithium iron phosphate (LiFePO₄) is a safer, heat-resistant battery that’s far less likely to overheat or catch fire.
2. Smart Monitoring System: A built-in Battery Management System (BMS) with eight temperature sensors helps prevent overcharging, deep discharging, and overheating by automatically adjusting battery activity.
3. Automatic Fire Suppression: Each battery module has a self-activating fire extinguisher that kicks in within seconds if overheating is detected.
4. Weatherproof Casing (IP66 Rated): Dustproof and water-resistant housing protects the battery from rain, dirt, and extreme weather, making it safe for outdoor use.

Modular Design: Add More Power, Anytime

Each iStore solar battery is a stackable module weighing 50 kg, with a capacity of 5 kWh (kilowatt-hours). You can connect up to six modules to increase storage to a maximum capacity of 30 kWh.

Wondering how many batteries your home will need? The average Aussie home with four people uses around 20 kWh of electricity daily, which equates to four battery modules (20 kWh total capacity). 

With our modular battery design, you’re not stuck with your original setup if your energy needs change later. If your family grows, you buy an electric car, or add a granny flat to your property, you can easily upgrade your battery system to keep up with the extra energy demand without replacing the entire system.

Warranty: We’ve Got Your Back

iStore solar batteries come with a 10-year performance warranty, guaranteeing reliable storage and consistent performance for years to come.

This warranty is not just peace of mind and a safety net; it’s a sign that at iStore, we back our technology to go the distance in Aussie conditions.
