I have a 3 Quatrro 2 units (5kVA) making up a 3 phase system. It has a Cerbo GX with touchscreen. Also a smart shunt connected to the Cerbo.
With battery and mains connected I was doing some output load testing to check operation. The system was working as expected when it suddenly shutdown. Nothing will restart. Battery voltage is present. There are no LEDs on anything. The Cerbo does not even show wifi or bluetooth lights. I am thinking the Cerbo has failed and the inverters are waiting on a signal that is never coming. Can anyone suggest what might have gone wrong?
