Runtime predictions for your loads

Based on 5,040 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	% of 48hr target
CPAP only (overnight)	60W	3.0 days	100%
Fridge only (cycle-averaged)	70W	2.6 days	100%
Wifi router + LED lights	55W	3.3 days	100%
Your full continuous load (215W)	215W	20.0 hr	42%
Microwave + base load (peak)	1300W	3.3 hr	7%
Window AC 8,000 BTU (avg)	700W	6.2 hr	13%

Detailed specs

Sourced from manufacturer datasheet · verified 1d ago

For 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
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.
