Daytime charging on solar surplus is the cheapest km available.
-
A wall-mounted AC switch unit tidies carport installations.
-
Battery storage covers the evening-charge case.
The economics are not subtle
Grid-charged motoring is already cheaper than petrol. Solar-charged motoring makes the fuel bill approach zero. The catch is timing: cars sit in driveways all day while panels produce at noon — exactly the overlap you want to exploit.
Charge when the sun does the work
If your car is home during the day, schedule charging against the solar surplus. The battery can cover the evening top-up case, and a modular system means you can add capacity when the car arrives rather than pre-buying for it.
Keep the install clean
A carport or garage install lives or dies on cable management and switching. A wall-mounted AC power switch unit with proper backup rating keeps the hardware tidy and the circuits protected.
One platform, one app
When the inverter, battery and charger share a monitoring platform, you see exactly which kilometres came from your roof. That visibility is half the satisfaction of driving on sunshine.
