Home Battery
Storage
Store surplus solar energy and use it in the evening. Keep the lights on during power cuts. Charge cheaply on overnight tariffs. One battery — multiple benefits.
Store Solar
Don't export your solar surplus at 4–5p/kWh. Store it and use it at peak time instead of paying 28p+/kWh from the grid.
Charge Off-Peak
Pair with Octopus Go, Agile or Economy 7 to fill your battery at 7–10p/kWh and discharge during expensive peak hours.
Backup Power
Certain batteries (Tesla Powerwall 3, GivEnergy) provide whole-home backup during grid outages — your lights stay on.
