When the battery lights are on, do you hear a clicking noise inside the inverter, and then the lights go out?

If so this highly likely to be the BMS motherboard in the inverter that's failed. I had it happen to me and the inverter had to be replaced under warranty,

Make a phone call to givenergy support in the morning.
