This morning around 7:30 my batteries went offline. After much trouble shooting this appears to be something to do with the inverter. If the primary battery is isolated I can power it up and it stays on, as soon as I flip the breaker the AC3 inverter starts making some clicking noises and the battery shuts itself down.
My installer is coming tomorrow to have a look but this looks like a hardware failure. The system has been up and running for nearly two years without isssue so far.
Has anybody else had any issues ?
