Sunplug: Solar EV Charging

Charge your electric car with the solar power your home already produces, and buy the rest from the grid in the cheapest hours.

Sunplug watches solar, home, grid and battery flows, then adjusts compatible cars and smart chargers to use the surplus without chasing every passing cloud. Set a ready-by time and let Sunplug decide: it plans each car's charge on your solar surplus first, then on the cheapest hours of your tariff.

• See live energy moving around your home
• See the grid price for the hours ahead, with live market prices across most of Europe
• A solar forecast for your home, with your past production and the planned charges, all in one place
• Any tariff: base, peak and off-peak with seasons and weekends, market prices or Tempo
• Set a ready-by time, a grid level and a price cap for each car
• Prioritise your home battery or your cars
• Keep charging calm through changing weather
• Review what charging cost you, where its energy came from and what it saved
• Choose the notifications you want, based on your tariff

Sunplug works with selected inverters, batteries, cars and smart chargers. Compatibility depends on your equipment and region. Some setups use the lightweight Sunplug Agent on your home network, so equipment credentials stay at home.

Sunplug is currently in beta. You need a Sunplug account and compatible equipment.
