Question 14

Q14:  How long can it run my device?

Accepted Answer

A: Runtime = Battery capacity × DoD × η ÷ (Device power+Self consumption) For
B500K, both DoD (Depth of Discharge) and η (inverter efficiency) are 90%, and
the self consumption is 3 W. If you run a 100 W light bulb with it, the runtime
will be: 5,120 Wh × 98% × 90% ÷ (100 W + 3 W) ≈ 43.8 hr Note: For reference
ONLY, actual results vary.
