Table
Battery Runtime by Load and Usable kWh
Battery Runtime by Load and Usable kWh reference with assumptions and boundary notes.
Reference boundary
Runtime arithmetic only. It does not include inverter surge, low-temperature derating, standby loads, or reserve requirements.
Reference table
Estimate runtime from usable battery energy and steady load.
| Load (W) | 1 kWh usable | 5 kWh usable | 10 kWh usable |
|---|---|---|---|
| 100 | 10 h | 50 h | 100 h |
| 250 | 4 h | 20 h | 40 h |
| 500 | 2 h | 10 h | 20 h |
| 1000 | 1 h | 5 h | 10 h |
| 2000 | 0.5 h | 2.5 h | 5 h |
| 5000 | 0.2 h | 1 h | 2 h |
