Does AC500 support charging and discharging at the same time?


How long will AC500 run my device?
Running time = battery capacity x DoD x η ÷ device rated power DoD: Depth of Discharge, η: local inverter efficiency. For AC500, both DoD and η are 90%. If you run a 1,000W microwave oven with a AC500 + B300S combo, the running time will be 3,072Wh × 90% × 90% ÷ 1,000W ≈ 2.5 hours
1) This formula doesn't apply to inductive loads with compressors, such as refrigerators, air conditioners, etc.
2) The above data is for reference ONLY.
