How long can it power your home?

Cali-Graf calculation

Average home load	Runtime from full
0.5 kW	≈ 24 h
1 kW	≈ 12 h
2 kW	≈ 6 h
3 kW	≈ 4 h
20 kW (full continuous power)	≈ 0.6 h

Runtime = 12 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.
