How to choose a home EV charger in Australia

Step 1: Look up your car. Everything follows from this.

Find your car's onboard AC charger rating and whether it's single- or three-phase. This is the hard ceiling on your home charging speed, and no amount of hardware spending moves it.

Then the decision more or less makes itself:

• Single-phase car (7 kW or less) — this is most BYDs, most MG4s, the Kia EV5 Standard Range, the Gen 1 Kona. Buy a 32 A single-phase charger. You are done. A three-phase charger cannot help you and a 16 A three-phase one will actively hurt.
• Three-phase car (10.5–11 kW) — Tesla, Polestar, Volvo, BMW, Mercedes, Ioniq, EV6, EV9, Sealion 7. If you already have three-phase power, buy an 11 kW charger. If you don't, an upgrade costs thousands to gain about 50% — worth it only if you genuinely need it.
• 22 kW car — a very short list: the facelifted Toyota bZ4X, a Polestar 4 with the optional 22 kW charger. If that's you and you have three-phase, buy the 22 kW box. You're one of the few people who'll use it.

Step 2: Be realistic about how much speed you need

You're not filling from empty. You're replacing yesterday's driving. A 7.4 kW charger adds roughly 40 km of range per hour, so an eight-hour off-peak window puts back about 320 km — far more than a typical day's driving.

The real question for most households isn't speed at all. It's whether the charger can reliably run inside your cheapest tariff window, or soak up your solar. That's where the money is.

Step 3: Now — and only now — compare hardware

Once power is settled, chargers differentiate on things people rarely ask about:

Solar diversion (if you have solar)

"Solar charging" means very different things across brands. True diversion modulates the charge rate to consume only your surplus rather than exporting it.

• Fronius Wattpilot and myenergi Zappi do true diversion and switch automatically between one and three phases. That switching matters more than it sounds: a car won't start charging below about 6 A, which needs ~1.4 kW of surplus on single-phase but ~4.1 kW on three-phase. Auto-switching means you start harvesting on a cloudy day instead of sitting idle.
• Tesla Wall Connector does not do true solar diversion without a Powerwall. Tesla's "Charge on Solar" requires one; it won't work from a generic inverter. Source
• SolarEdge and Sungrow do it well, but only paired with their own inverters.

Built-in DC fault protection

A charger with a built-in RDC-DD lets your electrician use a cheaper Type A RCD. Without it you need a Type B, which adds roughly $300–$400 to the install. Two chargers with the same sticker price can land hundreds apart once installed — worth asking before you compare quotes.

Configurable vs fixed

Some units — the Tesla Wall Connector, Zaptec Go 2, Sungrow — are a single model that your electrician configures for single- or three-phase. There's no separate SKU to choose. Others, like the myenergi Zappi and the Wallbox Pulsar, split by variant, so you must order the right one.

Yes, Wallbox is a brand — a Spanish manufacturer whose Pulsar Plus and Pulsar Max are sold here. It's also why we say "charger" rather than "wallbox" throughout this site: the generic use of the word collides with the company, and Australians don't say it anyway.

Load management

If your main supply is 63 A (common outside NSW), a 32 A charger takes half of it. Dynamic load management watches your switchboard and throttles the charger when the oven and aircon are on. Frequently a much cheaper fix than upgrading your supply.

What it all costs

As a planning figure, Solar Choice's installer-network data puts the national average home EV charger installation at $2,237 including hardware, basic installation and GST, as at July 2026 — with a real spread by state. Source

Solar Choice EV Charger Price Index, July 2026. This is the average across their own vetted installer network — useful as a planning benchmark, but it's one network's data rather than an independent national survey. Western Australians pay roughly 40% more than South Australians for the same job. The index updates regularly, so check the date before relying on it.

Broadly:

• Hardware: roughly $800–$1,900 for a good single- or three-phase charger.
• Simple install (near the switchboard, short cable run): $400–$1,300.
• Complex install (long run, old board, trenching): $1,800–$2,500+.
• Add-ons: ~$10–$15 per metre of cable beyond the first 10–15 m; Type B RCD $300–$400; switchboard upgrade from $400 up to several thousand.

Interesting wrinkle: the hardware price difference between single- and three-phase is often only $0–$100. The cost is in the electrical work. So "the three-phase one is barely dearer" is true of the box and misleading about the job.

Rebates: don't count on one

As at July 2026 there is no federal rebate for home EV chargers, and the state programs have almost all closed — the Northern Territory's grants ended 31 December 2025, Tasmania's loan scheme closed to new applications in September 2025, and Victoria, Queensland, WA and NSW have nothing for houses. The ACT's Sustainable Household Scheme is the main ongoing support, and from 1 July 2026 it carries 3% interest rather than being interest-free for most applicants.

Some councils offer grants for apartment and strata charging. If you're in a unit block, that's worth a look — it's the one place money still exists.

The short version

1. Look up your car's onboard charger.
2. If it's single-phase, buy a 32 A single-phase charger and stop.
3. If it's three-phase and you already have three-phase, buy an 11 kW box.
4. If it's three-phase and you don't, work out whether 50% faster is worth several thousand dollars. Usually it isn't.
5. Spend what you saved on solar diversion or a better tariff instead.
