We have a AC coupling off grid system with a Quattro 48/8000 together with a Fronius Symo 8.2, a 14,4 kWh Pylontech battery system a 5kVA genset and a Color Control device.
Today we have recieve the following alarm message:
Temperature L1 on VE.Bus System.
Looking teh system through the VRM we can see that alarms in teh alarm register, but don't see anymore details about this alarm.
Checking the battetry temperature log doesn't show any problem, so looks like the alrma doesn't refer to the battery temperature.
Could someone tell me what is this alarm about?
