Runtime predictions for your loads
Based on 3,072 Wh capacity · 95% LiFePO4 DoD · 90% AC inverter efficiency. Solar column assumes ~25% of rated input as sustained sun average. Phase-1 uses constant-load math; time-resolved multi-day SOC simulation is the Phase-2 north star.
| Load profile | Continuous draw | Runtime estimate |
|---|---|---|
| CPAP only (overnight) | 60W | 1.8 days |
| Fridge only (cycle-averaged) | 70W | 1.6 days |
| Wifi router + LED lights | 55W | 2.0 days |
| Your full continuous load (215W) | 215W | 12.2 hr |
| Microwave + base load (peak) | 1300W | 2.0 hr |
| Window AC 8,000 BTU (avg) | 700W | 3.8 hr |
