4.4.4. Estimated Operation Time
Operation time (estimated) = Battery capacity (Wh) × DoD × η ÷ (load power)
Note:
1)Load power and operation time are measured in watts and hours.
2)DoD refers to depth of discharge. B80 works at 90% DoD for longer battery life. η is the
conversion efficiency of the inverter, which is 90% for B80.
E.g. If you run a 40W refrigerator with B80, the operation time will be:
806Wh × 90% × 90% ÷ 40W ≈ 16 hrs
Note: Low temperature and excessive loads could greatly impact the battery capacity
and reduces its normal operation time.
