How long can it power your home?

Cali-Graf calculation · CEC Energy Storage System List
Average home loadRuntime from full
0.5 kW≈ 10 h
1 kW≈ 5 h
2 kW≈ 2.5 h
3 kW≈ 1.7 h
3.84 kW (full continuous power)≈ 1.3 h
Runtime = 5 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.
