The UK's Best Solar EV Charger
The myenergi Zappi is the UK's most popular solar-integrated EV charger, chosen by homeowners who want to maximise the value of their solar panels. Unlike standard chargers that draw entirely from the grid, the Zappi can detect your solar surplus and automatically divert it to your vehicle — effectively charging your car for free during sunny days.
East Anglia's above-average sunshine hours make the Zappi particularly effective. A typical 4kW solar system in Cambridgeshire or Suffolk can provide 60-80% of a typical driver's annual charging needs free of charge. At public charger rates of 60-80p/kWh, that represents £600-£1,000 in annual savings on top of your bill savings from the solar panels themselves.

Zappi Charging Modes Explained
Fast Mode
Charges at full 7kW from the grid regardless of solar output. Use when you need to charge quickly or don't have solar panels.
Eco Mode
Prioritises solar surplus but tops up with grid power to maintain minimum charge rate. Recommended for most users with solar — balances speed and free solar charging.
Eco+ Mode
Charges only from solar surplus — no grid power used. Will stop charging if solar output drops below the minimum threshold. Ideal for maximum free charging but can be slow in winter or cloudy weather.
