How long can it power your home?

Cali-Graf calculation · CEC Energy Storage System List

Average home load	Runtime from full
0.5 kW	≈ 20.2 h
1 kW	≈ 10.1 h
2 kW	≈ 5 h
3 kW	≈ 3.4 h
3.84 kW (full continuous power)	≈ 2.6 h

Runtime = 10.1 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.

Power control (PCS) capableYes
