What size solar inverter and battery do I need?

A typical home — living room, two bedrooms, kitchen — sized instantly, then tuned room by room.

Pick your appliances one by one and watch the system size itself.

Photograph your last electricity bill and we size the system on what you actually use. We read it right here on your phone — it never leaves your device.

Type it the way you’d say it out loud — the place, the bill, the things that can’t switch off. I’ll ask for whatever is still missing, then size the whole system.
