Home EV Chargers in Australia

7kW vs 22kW: Which Do You Need?

For most Australian households, a 7.4kW single-phase charger is the right choice. It will charge a 60–80kWh battery from 20% to full in 7–9 hours overnight — more than enough for the average daily commute. A 22kW three-phase charger is faster but requires three-phase power, which most Australian homes don't have. Check with your electrician before assuming you can install a 22kW unit. In practice, the charging speed difference between 7kW and 22kW rarely matters when you're charging overnight and the car sits plugged in for 8 hours.

Solar-Integrated Chargers: The Biggest Opportunity

If you have solar panels, a solar-integrated charger is the most valuable upgrade you can make. Chargers like the myenergi Zappi and Fronius Wattpilot dynamically match their charge rate to your surplus solar generation, so your car charges for free during the day. Without a solar-aware charger, you'd export that surplus at 2–5¢/kWh and then buy grid power at 30¢+ overnight — a significant and unnecessary cost. According to the Electric Vehicle Council's 2024 survey, about 80% of Australian EV owners who have solar charge primarily during the day. A solar-integrated charger is the right tool for that.

Single-Phase vs Three-Phase Installation

Most Australian homes have single-phase power (one active wire from the street). This limits your charger to 7.4kW maximum on a 32A circuit. Three-phase homes can access 11kW or 22kW chargers. To find out which you have, check your main switchboard — three-phase boards have three sets of circuit breakers. If you're unsure, an electrician can confirm during the quote process. Upgrading from single to three-phase supply costs $3,000–$8,000 depending on your location.

What is OCPP?

Open Charge Point Protocol (OCPP) is an open standard that lets chargers communicate with any compatible management platform. It matters for fleet operators, businesses managing multiple vehicles, or landlords with shared charging. For a single home installation, OCPP is optional. Some users value it for access to third-party smart charging apps that can optimise charging based on electricity spot prices. Chargers with OCPP include the Fronius Wattpilot, Wallbox Pulsar Plus, and Evnex E2 range.

Load Management

Load management lets the charger throttle its output when other high-draw appliances are running simultaneously, preventing nuisance tripping of your main circuit breaker. It's worth having if you run ducted air conditioning, an induction cooktop, an electric oven, or electric hot water system alongside evening charging. Most smart chargers include some form of load management. Check the product specifications before purchasing if this is a concern for your home.

Installation Costs

A Level 2 home charger installation in Australia typically costs $500–$1,500 for labour, depending on the complexity of your switchboard, the distance to your preferred charger location, and whether any new circuits need to be run. The charger supply cost is separate from installation. Quotes vary significantly between electricians — get at least two before committing. Some charger brands (Evnex, myenergi) have preferred installer networks that can simplify the process.

What About the Tesla Wall Connector?

The Tesla Wall Connector Gen 3 is the charger Tesla recommends for Model 3 and Model Y owners. It charges at up to 11kW (three-phase) or 7.4kW (single-phase) and integrates natively with the Tesla app for scheduling and monitoring. Non-Tesla vehicles can also use it via the Type 2 socket, though the Tesla app integration only works with Tesla vehicles. It's a quality unit at a competitive price and warrants consideration even if you're not exclusively a Tesla owner. Compare it with the full range on this page.

Common Questions

Can I install a home EV charger myself? No. In Australia, installation of a Level 2 EV charger requires a licensed electrician. The charger connects to your switchboard and must comply with AS/NZS 3000 wiring rules. Some portable Level 1 units (plugging into a standard 10A outlet) can be used without installation, but these charge at only 10–15km per hour.

How much does it cost to charge an EV at home? At 30¢/kWh, charging a 60kWh battery from empty to full costs about $18. For a daily commute of 50km (roughly 10kWh), the daily charging cost is around $3. This compares to approximately $8–12 in petrol for an equivalent ICE vehicle at current fuel prices.
