How long can it power your home?

Cali-Graf calculation

Average home load	Runtime from full
0.5 kW	≈ 27 h
1 kW	≈ 13.5 h
2 kW	≈ 6.8 h
2.5 kW (full continuous power)	≈ 5.4 h

Runtime = 13.5 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.
