Good morning guys,
We have an Axpert 5Kva Inverter, connected to 12 x 270Watt panels, connected in 4 x 3 panel strings and with 16 x 200Ah batteries connected as 4 x 4 banks of batteries. The system was opperating without any problems for about 5 weeks until the batteries were used without full daily recharge by pv. Since then we cant seem to get batteries fully charged and the system wil stop charging the batteries halfway through the day even with alot of daylight left. It only stop charging the batteries but still supply the load untill sun down. Need some advice on settings please.
