Runtime predictions for your loads
Based on 2,048 Wh capacity · 95% LiFePO4 DoD · 90% AC inverter efficiency. 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 | 1.2 days |
| Fridge only (cycle-averaged) | 70W | 1.0 days |
| Wifi router + LED lights | 55W | 1.3 days |
| Your full continuous load (215W) | 215W | 8.1 hr |
| Microwave + base load (peak) | 1300W | 1.3 hr |
| Window AC 8,000 BTU (avg) | 700W | 2.5 hr |
Detailed specs
Sourced from manufacturer datasheet · verified 1mo agoFor advanced shoppers. Plug types matter if you have a 30A RV; MPPT range matters if you plan custom solar arrays.
Battery behavior
| Cell chemistry | LiFePO4 |
| Cycle life @ 80% capacity | 3,500 |
| Dimensions | 18.1×10.6×12.0 |
| Parasitic loss (idle, AC off) | pending verification |
Why parasitic loss matters: for store-and-forget hurricane prep, even ~2W idle drain adds up — a fully charged unit can drain in months sitting in a closet.
