Hi, I have 2 x 5kW inverters connected in parallel and 2 banks of batteries (4 x 200Ah connected in series in each bank) connected in parallel. The battery capacity reduces to 70% from 95% on initial loading and thereafter slowly discharge at an acceptable rate. The connected load is about 750kW.
I tested the batteries with the battery analyser and they showed 100% State oh Health and 95% State of Charge before connecting the load.
What could be the problem
