My PMP122305100 when connected to shore power (30a selected on my cerbo screen) ramps up with louder and louder buzzing which causes a 100A breaker to constantly trip to my 400ah lifepo4 battery bank. I confirmed with my battery monitor its trying to dump over 99A into them before the breaker blows. Am I missing a setting on this inverter somewhere or is this defective and needs to be fixed or replaced?
Thanks.
