In this guide, we explore how the system works, its many advantages, what to consider before installation, and how iStore’s solar heat pump range can help your household transition to clean energy more affordably.

What is a Solar Heat Pump and How Does It Work?

A solar heat pump integrates two renewable technologies, a solar PV system and a hot water heat pump. Together, they create a powerful process that redefines household energy consumption.

Here’s how it works:

1. Solar panels (the PV components) generate electricity from sunlight. These panels can be installed on the roof or as ground-mounted systems, depending on your property.
2. That solar electricity powers the hot water heat pump, which is operated using renewable energy sources such as solar power, and then extracts thermal energy from the ambient air.
3. The hot water heat pump transfers this low‑grade heat energy into your home’s hot water system, effectively heating water for daily use with minimal dependency on grid electricity.

Alternatively, a solar hot water system uses solar collectors, which may include flat panels or tubes (such as vacuum tubes or collector tubes), to capture heat directly from the sun and transfer it to your water supply.

The combination of these systems multiplies efficiency, you’re not only using the sun’s power to run the hot water heat pump, but you’re also capturing free heat from the environment.

iStore’s advanced heat pumps are expertly designed to integrate with existing solar PV systems, making them ideal for Australian households that already have panels installed. This pairing maximises efficiency, reduces running costs, and ensures consistent performance no matter your location or energy needs.

Proper wiring and voltage matching are critical for the system to run smoothly and to prevent damage to equipment. Incorrect connections can lead to overheating, short circuits, or reduced system performance.

Does a Solar Battery Have To Be Professionally Installed?

In Australia, a solar battery must be professionally installed by a licensed electrician who is accredited for battery storage systems.

Here’s why:

• High Voltage Risks: Solar batteries store and discharge large amounts of energy. Incorrect installation can cause electric shock, fire, or system failure.
• Warranty Protection: Most manufacturers, including iStore, require professional installation to keep warranties valid.
• Regulatory Compliance: Australian standards (such as AS/NZS 5139 for battery storage) set strict rules on how and where batteries can be installed. Accredited installers know these requirements and ensure the system is compliant.
• Insurance Coverage: Many home and contents insurers will not cover damage or loss caused by a battery system that was not professionally installed. 

Step-by-Step Guide: How to Connect a Battery to a Solar Inverter

If you are a licensed electrician and accredited solar battery installer, here are the general steps to follow to connect a battery to a solar inverter.

1. Gather necessary tools and equipment. Have the required cables, connectors, safety gear, and the manufacturer’s installation manual ready before starting.
2. Switch off all power sources. Shut down the solar system and isolate the inverter by switching off its AC isolator (disconnecting it from the switchboard) and DC isolator (disconnecting it from the solar panels). Doing this stops electricity from flowing into or out of the inverter during battery installation, preventing electrical hazards.
3. Check compatibility. Confirm that the inverter supports the battery type and capacity. Hybrid inverters usually make this step easier with built-in battery compatibility.
4. Position the battery. Place the battery in a well-ventilated, dry location away from direct sunlight and extreme temperatures.
5. Connect wiring. Use the manufacturer’s instructions to connect the battery cables to the inverter terminals. Pay close attention to polarity, connecting positive (+) and negative (–) cables to the correct terminals, and confirm that all wiring matches the required voltage.
6. Secure connections. Tighten terminals and check that all cables are properly insulated and fixed in place to prevent movement or wear.
7. Configure the system. Power up the inverter, activate the battery system, and configure settings through the inverter’s monitoring platform or control panel.
8. Test the system. Run performance checks to confirm that the battery charges and discharges correctly, and that energy flows seamlessly between the panels, inverter, battery, and household or business supply.

Tips for Safe and Effective Installation

• Review Manufacturer Instructions: Always follow the battery and inverter manuals for correct wiring, communication settings, and configuration.
• Confirm Compatibility: Check that the battery chemistry (e.g., lithium-ion), capacity, and voltage are supported by the inverter.
• Install Protective Devices: Fit isolators, circuit breakers, and fuses rated for the system to safeguard against overloads and faults.
• Use the Right Cable Size: Select cables suitable for the current, voltage, and installation distance to minimise voltage drop and overheating.
• Maintain Correct Polarity: Double-check positive (+) and negative (–) connections before powering on.
• Choose Safe Placement: Position the battery in a cool, dry, and ventilated space, away from direct sunlight, moisture, and flammable materials.
• Follow Australian Standards: Install according to AS/NZS 5139 for battery storage systems and other relevant electrical codes, checking placement requirements, clearances, and fire safety measures.
• Test and Commission Properly: Verify charging and discharging functions, set up monitoring software, and confirm the system operates as intended before handover.

Working with Clean Energy Council–accredited installers brings these safety measures together for a safe, compliant installation. Certified professionals understand how to apply AS/NZS 5139 and other electrical standards, reducing risks and giving households and businesses confidence that their investment meets Australian safety and quality benchmarks.

What New Homeowners Need to Know

Imagine cutting down your hot water bills without cutting back on your showers. That’s the promise of heat pump hot water systems, an energy-efficient alternative to traditional electric or gas units that’s quickly gaining traction across Australia.

Instead of burning fuel to generate heat, these clever systems pull warmth from the surrounding air and use it to heat your water. The result? Lower running costs, reduced energy use, and a much smaller carbon footprint. 

How does heat pump hot water work? What are the benefits of heat pump systems? And what should you know before deciding if a heat pump is the right choice for your new home? We’ve got all the answers and more.

What Is a Heat Pump Hot Water System?

A heat pump hot water system transfers natural warmth from the air and uses it to heat your water supply, instead of relying on electricity or gas to create heat directly.

At the heart of a heat pump system are three key components.

1. Compressor: Increases the pressure and temperature of the refrigerant so it can release heat effectively.
2. Evaporator: Absorbs heat from the surrounding air into the refrigerant.
3. Condenser: Transfers the captured heat into the water stored in the tank.
   

Together, these parts work to provide reliable hot water with renewable energy.

How Does a Heat Pump Hot Water System Work?

1. The evaporator absorbs heat from the air. A small fan pulls in ambient air, and the evaporator draws out its heat.
2. Refrigerant converts the heat into usable energy. The cold refrigerant absorbs the heat, changes into a warm gas, and moves through the system.
3. The compressor boosts the temperature. The gas is compressed, its pressure rises, and it becomes very hot.
4. Heat transfers to the water in the tank. The hot refrigerant passes through a condenser coil wrapped around, or inside, the tank, releasing heat into the water.
5. The cycle resets, ready to repeat. An expansion valve drops the refrigerant’s pressure so it cools back to a liquid, then it returns to the evaporator to start again.

Benefits of Heat Pump Hot Water Systems

Energy Efficiency

Unlike electric water heaters that rely on electricity to directly generate heat, heat pumps only need a small amount of electricity to run the fan and compressor. The real work is done by drawing in natural warmth from the air, which is a free and renewable energy source.

This heating process uses far less power, reducing electricity consumption by around 75–85% compared to traditional electric systems.

Cost Savings

A heat pump may cost more upfront than a standard electric unit, but the long-term savings quickly add up. By using far less electricity to heat water, your energy bills drop month after month. Lower electricity costs mean more money left in the family budget for other priorities.

Over the life of the system, these savings can outweigh the initial purchase and installation costs. In many cases, households can also benefit from government rebates or incentives, making the switch even more affordable. 

Eco-Friendly

Heat pump hot water systems are one of the most environmentally friendly ways to heat water. By drawing renewable heat from the air instead of burning gas or using large amounts of electricity, they produce far fewer greenhouse gas emissions.

Switching from a conventional electric water heater to a heat pump can save around 0.3 tonnes of CO₂ per year, while replacing a gas system can save 1–2.9 tonnes annually, depending on the household size and energy use. That’s roughly the same as the emissions from driving 1,000–10,000 km in an average car.

For new homeowners, using a heat pump is a straightforward way to shrink your household’s carbon footprint and make a positive impact on the environment, without compromising on comfort.

Versatility

There are heat pump models to suit homes of all shapes and sizes. 

For example, the iStore 180L heat pump is ideal for households of up to 3 people, delivering enough hot water for daily showers, dishwashing, and laundry without unnecessary energy use. 

The larger iStore 270L heat pump is designed for medium to large families of 4–6 people, providing reliable hot water even with multiple showers, appliances, and higher daily demand.

With different capacities available, you can choose a system that provides plenty of hot water without wasting energy. This flexibility makes heat pumps a practical option for almost any new homeowner.

Heat Pump Water Heaters vs Traditional Water Heaters

Feature	Heat Pump Water Heater	Gas Water Heater	Electric Water Heater
Energy Efficiency	Uses renewable heat from the air; 3–4x more efficient than electric	Moderate efficiency, but depends on gas prices and supply	Least efficient; relies on electricity to generate heat directly
Energy Cost Savings	Households can save $500–$1,000 per year compared to electric systems, depending on household size and tariffs	Cheaper to run than electric, but often 20–40% higher bills than heat pumps	Most expensive; hot water bills can be 3–4x higher than with a heat pump
Upfront Cost vs Long-Term Investment	Higher upfront price, but can pay off through energy savings within 3–5 years	Moderate upfront cost; limited long-term savings compared to heat pumps	Lower upfront cost but very high lifetime operating costs
Environmental Impact	Low emissions; reduces household CO₂ by 0.3–2.9 tonnes per year, depending on size and energy source	Produces direct greenhouse gas emissions from burning fossil fuels	High emissions if grid electricity is coal-based
Versatility	Models available from 180L in size for 1–3 people to 270L+ for 4–6 people	Suitable for small to large households, but efficiency drops with higher demand	Available in various sizes, but costs escalate with larger households

How Heat Pump Hot Water Systems Work with Solar Panels

Heat pump hot water systems pair seamlessly with solar panels, a solar inverter, and a solar battery. 

When solar panels generate electricity during the day, that energy can power the heat pump’s compressor and fan. Instead of drawing electricity from the grid, hot water is heated using clean, renewable energy from the sun.

If you also have a solar battery, the system becomes even more flexible. Excess solar energy captured during the day can be stored in the battery and used later to run the heat pump at night or in the early morning. That means you’re not limited to heating water only while the sun is shining; you can tap into stored energy whenever you need it.

Benefits of Pairing Heat Pumps with Solar Energy

• Lower Energy Bills: Powering your heat pump with solar can reduce or even eliminate hot water costs.
• Smarter Energy Use: Heat pumps can be timed to run during peak solar production hours, making the most of free, renewable power.
• Reduced Grid Reliance: Adding a solar battery means you can enjoy hot water without depending on grid electricity, even in the evenings.
• Minimal Carbon Footprint: Combining a heat pump with solar panels creates one of the cleanest, most sustainable hot water solutions available.
• Future-Proof Investment: With rising energy prices, this setup protects your household from higher running costs down the track.

Installation and Maintenance of Heat Pump Hot Water Systems

Professional Installation: What to Expect

Most heat pump hot water installations take around 3–6 hours, depending on the site and whether an old system needs to be removed. Larger or more complex setups may take a little longer. 

A licensed installer will handle the setup for you, but it helps to know the steps involved.

1. Site Inspection: The installer will check your home to find the best spot for the heat pump. Proper placement is key. Heat pumps need airflow to draw in ambient heat, so installing them in an open or semi-open space (not in a closed garage or small shed) means maximum efficiency.
2. System Positioning: They will place the heat pump unit and storage tank on a stable base, away from confined spaces or areas sensitive to noise.
3. Plumbing Connections: They’ll then connect the pipes from the unit to your home’s water supply.
4. Electrical Wiring: They’ll connect the system to your home’s power supply, often through a dedicated circuit, which is a separate electrical line and breaker that only serves the heat pump to prevent overloading and improve safety.
5. Commissioning and Testing: Finally, the installer will run the system, check water temperature, and ensure everything is operating correctly.

Homeowner Maintenance

Keeping your heat pump in good condition helps extend its life and maintain efficiency. With a bit of care, your heat pump hot water system can deliver reliable, efficient hot water for perhaps 10 years or more.

Here’s what you can do:

1. Clear away dust, leaves, and debris from the air intake and fan located on the side or top of the outdoor unit every few months.
2. Keep the surrounding space clear, maintaining at least a metre of open space around the unit so air can circulate freely. Avoid storing garden tools, bins, or plants nearby.
3. Inspect the system for leaks and strange noises, and report anything unusual to a technician.
4. Schedule regular servicing from a professional every 1–2 years. They will check refrigerant levels, electrical components, and overall performance.

Government Rebates and Incentives for Heat Pumps

Federal

The federal Small-Scale Renewable Energy Scheme (SRES) encourages households to install renewable energy systems, such as solar panels and air-source heat pumps.

When you install an eligible system, you’ll receive Small-Scale Technology Certificates (STCs). These certificates have monetary value, and you can sell them to energy retailers or other liable entities who need them to meet their renewable energy obligations under the scheme. 

You can apply the value of these STCs as an upfront discount toward the cost of installing your heat pump system, effectively reducing the purchase price.

The number of STCs you receive depends on several factors. Larger, more efficient systems in sunnier areas or homes that use a lot of energy to heat water will typically qualify for more STCs.

This scheme is reducing until it ends in 2030, so the amount you can save on your heat pump installation will decrease over time. 

State

The NSW Government helps households save money on energy by offering incentives to upgrade to energy-efficient appliances and equipment. The incentive works as a discount taken off your quote for the installation of a heat pump hot water system.

If eligible, you can receive a discount of up to $640 when you replace an electric water heater with an air source heat pump. When you replace a gas water heater, you can receive a discount of up to $330.

In Victoria, eligible households can receive a discount of up to $630 for replacing an inefficient electric hot water system with a heat pump and up to $560 for replacing an inefficient gas water heater.

To find out what rebates or incentives apply in your state, visit your state government’s energy website or check the federal government’s energy.gov.au site, which lists current programs across Australia. You can also ask your installer, as many are registered providers under these schemes and can confirm eligibility and apply the discount directly to your quote.

Eligibility and the Application Process: What You Need to Do

1. Choose an Eligible Heat Pump: Your heat pump must be an approved model (e.g., iStore) on the Australian Government Clean Energy Regulator Register and must have a capacity under 425 litres to qualify for STCs.
2. Choose a Retailer and Licensed Installer: Choose a reputable retailer and confirm the installer holds the correct state or territory licence with your local authority.
3. Decide on Using a Registered Agent: Most households assign STCs to an agent, who calculates their value and applies it as an upfront discount. You can find agents in the REC Registry.
4. Install Your Heat Pump: Have the system professionally installed.  
5. Create and Register STCs (if not using an agent): Set up an account in the REC Registry and lodge your application for STCs within 12 months of your heat pump installation. Upload the documents required by the Registry. Allow 4–6 weeks for validation and registration.

How Can I Choose the Right Heat Pump for My Home?

Choosing the right heat pump hot water system comes down to matching your household’s needs with the right size and setup. 

Here are some practical tips.

• Consider your household’s size and hot water usage. A 180L system suits 1–3 people, while a 270L or larger model is better for families of 4–6.
• Consider your climate. Most heat pumps work well across Australia, but in cooler regions, look for models specifically designed for low ambient temperatures.
• Look at energy ratings. Higher efficiency ratings mean bigger savings on bills over time.
• Think about installation space. Heat pumps need good airflow, so choose an outdoor or well-ventilated location with clearance around the unit.
• Plan for solar integration. If you have solar panels, make sure your heat pump can be timed to run during the day to maximise free energy use.
• Check rebates and incentives. Federal and state government programs may reduce your upfront costs, making the system more affordable.
• Compare warranties and support. Longer warranties and responsive after-sales service give peace of mind and protect your investment.

Solar isn’t just about generating electricity anymore; it’s about keeping that energy in your hands. 

For Australian households and businesses, solar battery storage is becoming the key to true energy independence. By storing the power solar systems produce during the day, you can rely less on the grid, cut down on energy bills, and enjoy peace of mind when demand spikes or outages hit.

What is solar battery storage? What benefits do solar batteries deliver in terms of cost savings, safety, and sustainability? We’ve got the answers you need before deciding if a solar battery is a smart move for your home or business.

What is Solar Battery Storage and How Does it Work?

A solar battery stores the excess energy solar panels produce during the day. Instead of sending that unused electricity back to the grid, the battery holds onto it so you can use it later at night, on cloudy days, or during a blackout.

Here’s how it works:

1. Solar panels generate power when the sun is shining.
2. Your home or business uses the power it needs first.
3. Any extra energy is stored in the battery instead of being exported to the grid.
4. The battery discharges stored energy when your panels aren’t producing enough to meet demand.

Benefits of Solar Battery Storage for Homes and Businesses

• Energy Independence: Reduce reliance on the grid and take control of how and when you use solar power.
• Cost Savings: Store excess solar energy to use during peak tariff times, helping to cut electricity bills.

The financial support available through solar rebates is helping drive this surge towards solar energy.

How can you take advantage of a solar rebate for business to make solar more affordable? 

We’re here to answer that question. We’ll also show you how our tailored solar solutions can help you unlock long-term savings while doing your part to contribute to a cleaner Australia.

What Is the Solar Rebate for Australian Businesses?

The federal solar rebate for businesses is available through the Small-Scale Renewable Energy Scheme (SRES). The Australian Government introduced this initiative to encourage investment in clean energy by lowering the upfront cost of installing solar systems.

Instead of receiving a direct cash rebate, your business earns Small-Scale Technology Certificates (STCs) when you install eligible solar panels and inverters. Each STC represents a set amount of renewable energy your system is expected to generate over its lifetime.

These certificates have a market value and can be sold through your solar installer, who will apply the discount to the cost of your installation.

State-Level Solar Rebates For Business

Some state-based solar rebates for businesses are also available.

The solar rebate for businesses in NSW is currently called the Solar Battery VPP Incentive. This incentive offers up to $1,500 to small businesses that install an eligible solar battery and connect it to a Virtual Power Plant. 

In South Australia, the Powering Business Grant offers eligible businesses funding of $2,500–$75,000 to purchase solar batteries and solar panels paired with a battery storage system.

Benefits of Solar Rebates for Businesses

• Upfront Cost Savings: Solar rebates reduce the initial investment needed for a system, making it easier for your business to switch to renewable energy.
• Long-Term Cost Savings: With a lower installation price and reduced reliance on the grid, your business can benefit from ongoing savings on electricity bills.
• Environmental Impact: Installing solar panels helps reduce greenhouse gas emissions and supports your business’s commitment to sustainability, which can also enhance your brand reputation.
• Energy Independence: Generating your own clean power reduces exposure to rising energy prices and supply disruptions, giving your business more control over energy use.
• Tax Incentives: Your business may be eligible for tax deductions or depreciation benefits on solar systems, improving the overall return on investment.

Eligibility Requirements for Solar Rebates

To access the Small-Scale Renewable Energy Scheme (SRES), your business needs to install an eligible solar PV system under 100 kW in size with an annual electricity output of less than 250 MWh. The system must use approved products and be installed by a Clean Energy Council–accredited installer. 

The number of Small-Scale Technology Certificates (STCs) your business receives depends on

• Installation date
• Geographical location
• Amount of electricity generated
• Solar battery capacity
• How you choose to create your certificates: each year, every five years, or all at once for the full deeming period upfront

For state-based solar rebates, eligibility requirements differ depending on the program. In most cases, your business must operate from a commercial premises in that state or territory, use accredited products and installers, and meet certain conditions such as business size, energy use, or co-funding contributions.

To check whether your business qualifies for federal or state rebates, head to your state or territory government’s official energy website. You can also speak with a Clean Energy Council–accredited solar installer, who can explain what incentives apply to your business and manage the rebate process for you.

Ever wondered why your solar panels pump out all that energy during the day, but you’re still paying the power company at night? The missing piece is a solar battery. 

Solar panels only generate power while the sun is shining. Without a solar battery, any unused energy gets sent back to the grid instead of being saved for when you need it, like cooking dinner or binge-watching Netflix after dark.

The big question is: “What size solar battery do I need?” Pick too small, and you’ll run out of juice. Go too big, and you’ll overspend. 

Let’s look at what you should consider when buying a solar battery so you know exactly what size battery will work for your home.

Why Is Choosing the Right Solar Battery Size Important?

If your solar battery is too small, it won’t hold enough energy to cover your evening use. You’ll be left relying on grid electricity that’s expensive and generated mainly from non-renewable fossil fuels.

On the other hand, a battery that’s too large means you’ve paid for storage you rarely, if ever, fill, which is an unnecessary hit to your budget. 

So how do you figure out “What size solar battery do I need for my house?” Consider the following factors.

Factors to Consider When Sizing Your Solar Battery

Daily Energy Usage

Start by calculating your home’s average daily electricity use. Knowing your usage means you can choose a solar battery that matches your energy needs.

Check your electricity bill. It usually lists your total energy use over a billing period. Divide that by the number of days to get your daily average. Alternatively, note the reading on your meter at the same time on two consecutive days, then subtract to find the kWh used in 24 hours.

For reference, here are some typical household energy usage figures:

• Small Households (1–2 people): 8–17 kWh/day
• Medium Households (3 people): 18–20 kWh/day
• Large Households (4–5+ people): 21–25 kWh/day or more

Solar Panel Capacity

Solar panels set the limit for how much energy you can produce and store each day. A larger 6–10 kW system can generate far more electricity than a smaller 3 kW system, giving you more excess energy to put into a battery. 

The efficiency of your panels also matters, since higher-efficiency models produce more power from the same amount of sunlight.

Panel placement affects how efficiently your system performs. If your roof is partly shaded or panels face away from the sun, your overall output will be lower, which means the battery may not charge to full capacity. In this case, installing a large battery won’t deliver value, because the panels can’t generate enough power to fill it.

Usage Goals

Your reasons for installing a solar battery will strongly influence the size you need.

• Backup Power: If your main goal is backup power during blackouts, you may only need a smaller battery that can power essentials like lights, Wi-Fi, and the fridge. A larger battery would be necessary if you want to keep high-demand appliances, such as air conditioning, running as well.
• Off-Grid Living: If your home is not connected to the grid, you’ll need enough storage to cover all your daily energy needs, plus extra capacity for cloudy days. 
• Reducing Energy Bills: If your focus is on saving money rather than complete energy independence, a mid-sized battery is often enough. It can store daytime solar energy for use in the evening, helping you avoid buying expensive grid power during peak hours.

Location and Climate

Where you live has a big impact on how much solar energy your panels can produce and how large a battery you need. 

Homes in sunny regions generate more solar power, so a smaller battery may be enough to store the excess energy. Cooler or cloudier regions get fewer peak sun hours, which means you may want a larger battery to store extra energy when it’s available. 

These are the average peak sun hours per day across major Australian cities:

City	Average Peak Sun Hours per Day (Approx.)
Brisbane	5.6 hours
Sydney	5.3 hours
Melbourne	4.7 hours
Tasmania	3.5 hours
Adelaide	5.3 hours
Perth	6.0 hours
Northern Territory	6.5 hours

Seasonal changes also play a role. Households in southern states often use more electricity in winter for heating, while northern states may have higher summer demand from air conditioning.

Future Energy Needs

When choosing a solar battery, consider how your energy needs may grow in the future. Factoring in future changes helps you avoid needing an upgrade a few years down the track.

If you plan to have more people living under your roof, expect higher energy demand from extra appliances, heating, cooling, and day-to-day living.

If you plan to get an electric vehicle, this can significantly increase your electricity use. Charging can require 6–12 kWh per night, depending on the car and driving habits.

Common Solar Battery Sizes and Their Uses

• 5 kWh: Suited to smaller households or those wanting minimal essential power backup during power outages.
• 10 kWh: Storing enough solar power to cover evening use and reduce reliance on grid electricity.
• 15 kWh+: Ideal for larger families, homes with high-demand appliances, or those considering partial or full off-grid living.

Benefits of Modular Solar Battery Systems

Many solar batteries are modular, which means you can start small and add more capacity as your energy needs grow. 

For example, iStore solar batteries come in stackable 5 kWh modules. You can connect up to six modules, giving you flexibility to scale from 5 kWh to 30 kWh of storage.

How to Calculate the Right Solar Battery Size for Your Home

Here’s a simple guide to figure out “What size solar battery do I need for my house?”

1. Calculate your daily energy use. Check your electricity bill or meter to see how many kilowatt-hours (kWh) your household uses on average each day.
2. Decide how much of that you want covered. Do you just want to reduce your evening bills, keep the lights and fridge on during blackouts, or aim for full coverage? Your goal will determine how much storage you need.
3. Factor in your solar panel output. The size and efficiency of your solar system, along with peak sun hours in your area, affect how much energy you can generate to charge your battery.
   

Simple calculation:

Take your average daily energy use and multiply it by the percentage you want the battery to cover.

For example:

• Daily energy use = 20 kWh
• Desired coverage = 75% (0.75)
• 20 × 0.75 = 15 kWh battery
  

Still unsure? You don’t have to crunch the numbers alone! iStore’s solar battery experts can calculate the right size for your home and recommend a system that fits your budget and future energy goals.

FAQs

How Do I Know What Size Solar Battery I Need?

The right solar battery size depends on your daily energy use, how much of that you want to cover, and the output of your solar panels. 

A quick way to estimate is to multiply your average daily usage (in kWh) by the percentage you want stored. 

Is a 10kWh Battery Enough for My Home?

A 10 kWh battery suits most medium-sized homes, as it can store enough energy to cover typical evening use and reduce reliance on grid power. For example, a 10 kWh battery can run essentials like lights, a fridge, Wi-Fi, and a TV, plus a few hours of air conditioning or other appliances. 

What Factors Affect Solar Battery Capacity?

Solar battery capacity is influenced by daily energy use, the size and efficiency of solar panels, peak sun hours, and usage goals, whether that’s backup power, bill savings, or going off-grid. Adding more people to the household or charging an EV can also affect battery size.

Can I Add More Battery Capacity to My Solar System Later? </h3>

Many modern solar batteries are modular, so you can start small and add more capacity later as your energy needs grow. Just make sure your solar system and inverter are compatible with expansion.

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.

• 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.
