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.

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.
