JUST POWER ON 25
To estimate the operation time of the AC2A, consider the load you're applying:
• For high-power loads (above 100W):
Operation time = Battery Capacity (Wh) x DoD x η ÷ Load Power
• For small-power loads (below 100W):
Operation time = Battery Capacity (Wh) x DoD x η ÷ (Load Power + AC2A Self-con-
sumption)
Note: DoD refers to the depth of discharge. AC2A works at 90% DoD for longer battery life.
η is the conversion efficiency of the inverter, typically over 85% for AC2A.
The self-consumption of AC2A is approximately 7.5W.
E.g. If you have a 40W refrigerator, you can run it for about 3.3 hours.
Operation time = 204.8Wh × 90% × 85% ÷ (40W + 7.5W) ≈ 3.3 hours.
Please keep in mind that the estimated operation time provided is for reference
purposes and may vary based on actual usage conditions. Factors such as low temperature
and excessive loads can significantly affect the battery capacity, leading to a reduction in
the average operation time.
