Hi Guys,
Recently I have installed a 75kWp Solar System on one of the roofs. I used fronius Inverters (20kW x 2; 12.5kW x 1). All AC outputs of these inverters are combined in a separate solar LT AC Combiner Box (LT Panel/ ACCB). From here a single 4 core cable is drawn and connected to Clients LT Panel (Injection Point).
The problem here is, recently my 12.5kW intverter is tripping with Error "102" - AC Voltage too high. But other inverters are working normal. My question is, if all three inverters are connected on a same bus bar in Solar ACCB, why only one inverter records over-voltage and other function normal?
I am planning to look at the inverters output voltage range of all inverters, to check whether 12.5kW has narrow range set compared to other inverters. Say, all inverters have same range. what would be my next step to troubleshoot this issue?
PS: Error is occurring randomly and inverter goes to normal operation after some time.
