The cleanest match to the whole idea. Its built-in time-of-use control watches your tariff, charges the battery when power is cheapest overnight and runs your home through the pricey peak — no app-fiddling, no solar needed. Expandable if you move somewhere bigger.

Before you buy
Plug-in grid-charging batteries are a new category in the UK. Tell your home insurer, check the unit's current UK certification, and if you rent, confirm it with your landlord. Depending on your setup you may need to notify your network operator (DNO). Savings shown are estimates, not your actual bill.
