I have a system which is about three months old, 2x Kodak king UPS inverters, with PV and a 20kWh Pylontech battery back up. System was working fine until friday past. Customers eskom has been down since Thursday, now the system keeps giving hassles. The master inverter shows battery full, whilst the slave keeps giving a battery low error. What must I look for regarding faults, batteries are all still balanced and fully operational, but system literally keeps switching its self on and off. Would an ICC(inverter control center) sort this issue, or is that, as far as I understand, simply for online monitoring?
