Trickle charging vs dedicated EVSE: what's the difference?
Most EVs come with a portable charging cable that can plug into a standard 10A household GPO (general purpose outlet). This is sometimes called 'trickle charging' or 'Mode 2 charging', and it typically delivers around 2.4 kW — enough to add about 15 km of range per hour. For many owners, this is sufficient if you plug in overnight. However, if you have a larger battery, do regular long-distance driving, or simply want the peace of mind of a full charge every morning, a dedicated home EVSE (Electric Vehicle Supply Equipment) — commonly called a 'wall charger' or 'Mode 3 charger' — is a much better option. A typical 7.4 kW single-phase home charger will add around 40 km of range per hour, charging most EVs from near-empty to full in 8–10 hours. Some homes with three-phase power can access 22 kW charging, which can fully charge most EVs in under 4 hours.
How much does home charger installation cost?
A complete home EV charger installation — including the EVSE hardware and professional installation by a licensed electrician — typically costs between $800 and $2,000 in Australia. The wide range reflects several variables: the EVSE brand and model (budget options from brands like Ocular start around $400 hardware-only; premium smart chargers from Wallbox or Zappi can cost $1,500+), the complexity of your home's electrical setup, whether your switchboard needs upgrading, the distance from your switchboard to the installation point (usually a garage wall), and state-based electrician labour rates. It's worth getting at least three quotes from qualified electricians who have experience with EV charger installation. Some EV manufacturers, including Tesla, offer installation bundles through approved installers that may be more cost-effective.
Should you integrate with solar?
If you have rooftop solar, integrating your EV charging with your solar system can dramatically reduce your fuel costs. The principle is simple: instead of exporting surplus solar energy to the grid at the low feed-in tariff rate (typically 5–10 cents/kWh), you store it in your EV battery where it offsets the cost of petrol or grid electricity. Smart chargers like the Zappi, SolarEdge EV Charger, or Fronius Wattpilot can communicate with your solar inverter and automatically ramp up charging when surplus solar is available. This approach is especially effective if you work from home or can charge during the middle of the day. Looking further ahead, Vehicle-to-Home (V2H) technology — already available in Japan on some Nissan and Mitsubishi models — will allow bidirectional charging, letting your EV battery power your home during peak-rate evening periods or grid outages.
Finding a licensed EV charger installer
In Australia, EV charger installation must be performed by a licensed electrician — this is a legal requirement in all states and territories. However, not all electricians have experience with EV charging systems, and it's worth specifically seeking out those who do. The Clean Energy Council maintains a list of accredited installers through its Approved Solar Installer program, and many of these electricians have EV charging experience. You can also check the Clean Energy Council's EV Charging Association for specialist providers. When getting quotes, ask specifically about their experience with your EV brand (some vehicles have quirks that affect installation), whether they can provide a warranty on the installation, and whether they can advise on optimal charger placement for your property. Always ensure the installer provides an Electrical Safety Certificate upon completion.
