JUST POWER ON 27
To estimate the operation time of the AC180T, consider the load you're applying:
• For high-power loads (above 300W):
Operation time = Battery Capacity (Wh) x DoD x η ÷ Load Power
• For small-power loads (below 300W):
Operation time = Battery Capacity (Wh) x DoD x η ÷ (Load Power + AC180T Self-con-
sumption)
Note: DoD refers to the depth of discharge. AC180T works at 90% DoD for longer battery
life.
η is the conversion efficiency of the inverter, typically over 90% for AC180T.
The self-consumption of AC180T is approximately 15W.
E.g. If you have a 65W refrigerator, you can run it for about 14 hours.
Operation time = (716.8 × 2) Wh × 90% × 90% ÷ (65W + 15W) ≈ 14 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 tempera-
ture and excessive loads can significantly affect the battery capacity, leading to a
reduction in the average operation time.
