An intelligent EV charger integrated with your solar system can prioritise your own spare daytime solar generation for charging, only drawing from the grid or battery when solar surplus runs out — effectively turning your daytime solar surplus into free kilometres. For a household that's already invested in solar, that's often the single highest-value addition you can make to the system.
Plugging an EV into a standard powerpoint overnight works, but it means charging almost entirely on grid electricity at whatever rate your retailer charges after dark. A smart charger flips that around.
Charging an EV from a standard 10A or 15A household powerplug is the simplest option and requires no additional installation beyond confirming your circuit can safely handle sustained load. It's slow — typically adding around 10–15km of range per hour — which is fine for a car that always has overnight time to charge, but it offers no ability to intelligently track solar output.
A dedicated single-phase (typically up to 7kW) or three-phase (up to 22kW, switchboard and network-dependent) EV charger is hardwired to your switchboard and can add 40km or more of range per hour. Beyond raw speed, the real advantage is intelligence: modern units can be set to solar-priority mode, dynamically adjusting charge current to match your available solar surplus in real time.
An intelligent charger connected to your system's monitoring and metering setup constantly checks how much solar power is being exported versus consumed. When there's spare solar — say your panels are producing 5kW and the house is only using 1.5kW — the charger ramps up to use that 3.5kW surplus for the car, rather than exporting it at a low feed-in tariff. If a cloud passes over or household usage spikes, the charger automatically scales back, or can be configured with a minimum charge guarantee to ensure the car is ready by a set time.
For households with a battery installed, the logic can be layered further — some setups prioritise battery charging first to secure evening household backup, then direct remaining surplus to the EV, with the priority order configurable to match what matters most to you.
A typical EV with a 60–75kWh battery, charged predominantly from a 10kW solar system's midday surplus using a solar-priority fast charger, can cover the majority of an average Sydney commuter's weekly driving on power that would otherwise have exported to the grid at a low feed-in rate. Over a year, that's a meaningful chunk of "free" driving.
We can design and install an EV charger as part of a new solar and battery system from the outset, sized and wired correctly from day one, or add one to an existing Blue Energy Solar installation. If you already have solar with another installer, we can still assess whether your current inverter and metering setup supports solar-priority charging.
