Capacity & power

CEC Battery List

How long can it power your home?

Cali-Graf calculation
Average home loadRuntime from full
0.5 kW≈ 54 h
1 kW≈ 27 h
1 kW≈ 27 h
Runtime = 27 kWh usable (datasheet) ÷ load. A typical home averages 1–2 kW; air conditioning and EV charging use much more. Inverter and wiring losses shorten it.
