What You Need to Know Before Installing a Home EV Charger

Sunflow Energy Team 14 January 2026 4 min read

Installing a home EV charger is usually straightforward, but a few site-specific factors determine cost, timeline and the right charger for your property.

First, your switchboard needs enough spare capacity for the charger's load. Older homes with outdated boards sometimes require an upgrade before a charger can be safely installed.

Second, single-phase vs three-phase power availability determines your maximum charging speed — most homes can install a 7kW single-phase charger, while three-phase properties can go up to 22kW.

Third, if you're on solar, a solar-smart charger can automatically prioritise charging your car from excess solar generation instead of the grid, maximising your savings.
