I've got a 3-inverter off-grid 12000XP system hooked up to 6 indoor batteries (84kWh). I'm gradually installing strings of 8 375W panels to build out a 48-panel system, in the process of doing so the (+) wire from a not-yet-hooked-up MPPT on one of the inverters arced to the grounded corrugated roof, I forgot to tape off the end of the wire:
It was a bit surprising to me that an MPPT with no panels connected would arc like that. The inverter showed an overcurrent error in the logs and despite a full-system power down (all breakers and switches off, left off for 10 minutes) the inverter is still stuck in standby mode after booting up. Thankfully the two other inverters are able to supply all my needs. Does anyone know how to get the 12000XP out of standby? The fault condition is resolved (electrical tape on the ends of the wires).
