The phase of your home supply sets the ceiling on how fast you can charge at home. It is the first thing a good installer checks, and you can usually tell from your switchboard.
What each delivers
- Single-phase: up to 32 A at 230 V, so about 7.2 kW. Adds roughly 40 km of range per hour.
- Three-phase: 11 kW or 22 kW depending on the charger and car, adding 60-120 km per hour.
Which do you have
Most Australian homes are single-phase. Look at your main switch: a single large switch usually means single-phase, while three linked poles indicate three-phase. We confirm it from your switchboard photos when we quote.
Is three-phase worth it
For daily driving, 7 kW overnight is almost always enough, you wake up full. Three-phase matters if you drive very high distances, want fast top-ups, or are charging more than one EV. Upgrading from single to three-phase typically runs from about $1,000 to $3,000 or more depending on your network connection, so we only recommend it when the driving justifies it.
