12V / 24V / 48V LiFePO4 Solar, RV & Inverter Runtime Calculator
KURZANTWORT & TECHNISCHE ZUSAMMENFASSUNG • OFF-GRID & INVERTER FORMULA
Inverter Runtime (Hours) = (Nominal Voltage × Amp-Hours × Depth of Discharge × Inverter Efficiency) ÷ Load Watts. A standard 12V 100Ah LiFePO4 battery (1,280Wh) running at 90% DoD through a 90% efficient pure sine wave inverter delivers 1,036Wh of usable AC power—running a 400W load for 2 hours 35 minutes or a 65W 12V camper fridge for ~17.5 hours.
