I have 1 ab1000 and 1 ab2000. Yesterday afternoon they were both at 90%. I set the output to the house 90watt. This morning ab1000 is at 26% and the ab2000 is at 0% (i set the discharge threshold = 20%).
How is it possible? In less than 8 hours the battery went down from 90% just giving 90watt to the house.....this system is not reliable, how can i trust this numbers?
Do you know if there is some ways to solve this problem?
