My app is showing the battery’s cannot be seen by my inverter and the main battery will not turn on it clicks a few times and then shuts down.
I am still waiting to hear back from GV .
Any clues?
It sounds very much like the inverter BMS Board, I had the same happen to mine.
If you turn the power breaker off that feeds the battery, its either on the side of the battery or a separate unit (depends on the battery size)
Turn it off, then try turning the battery on, and if it stays on, but with the power breaker on the battery clicks and powers off, then its the inverter that has failed.
Will have to be replaced by GivEnergy under warranty.
