A smart charger can watch how much spare power your panels are making and send only that to the car.
- Solar-only mode: charges with spare solar, never from the grid
- Solar plus mode: tops up from the grid when the sun drops
- Overnight mode: charges at the cheapest rate after midnight
Plug in when you get home, even if the battery is half full. The charger decides when to use the sun. Luke, EV charging technician
Most drivers cover two thirds of their miles from the roof between April and September.
