I have four Growatt inverters and five Sun God 5 kW batteries. I also have Solar as a source of energy. My problem is that when the electricity is off during load shedding the batteries do not discharge at a equal rate. I would have one battery on 54% charge and another battery on 21% charge, the other three with high SOC in between but when that battery gets to 20% the entire system closes down. There is still sufficient charge in the other four batteries to keep the system going for at least another 40 minutes to an hour but because one battery got to 20% the entire system closes down. I was led to believe that the Growatt inverters would discharge the batteries at an equal rate so that maximum discharge is obtained from the five batteries. Does anybody have any ideas on what settings need to be set to the host inverter to ensure that the batteries discharge at an equal rate?
