What size battery do you need?

Four quick questions. We'll tell you the right battery size for your home - and which models to ask about.

How we recommend

The logic behind the size.

Bill → consumption

Your quarterly bill tells us your total kWh, which we estimate to evening kWh (the part a battery actually offsets).

Household → load shape

Bigger households mean bigger peak loads in the 4–10pm window. The battery has to cover more.

Solar + EV → future-proofing

If you have big solar or plan an EV, you want enough battery capacity to absorb those flows.
