This calculator estimates battery runtime from amp-hour capacity, nominal voltage, continuous load, and a usable capacity fraction. It uses the same planning math as SunPowerLogic setup examples — not a guarantee of field performance for every chemistry or load profile.
Estimated runtime at continuous load
5 hr 24 min
100 Ah × 12 V
Planning assumption — do not treat as manufacturer depth-of-discharge guarantee.
1,200 Wh × 90%
1,080 Wh ÷ 200 W
Recommendations are generated from published specifications in the product catalog. No products are hard-coded — suitability is computed at runtime from listed capacity values.
