I need some help please. my system is two multiples II 3000 48v. This is in my RV. running in split phase. All was working great for 2 month era then I had an overload when I was inverter only. I usually share load with shore at 8 amps per leg to keep my electric bill down.
ever since the overload it won’t come out of passthru mode. I have tried to reset it by turning off the mains and the unit for 10 sec. No luck. I update firmware updates and even tried to factory reset each invert and then go back to split phase.
the odd thing is when I disconnect the mains the dc voltage the the inver sees is not present. Did I pop the internal fuses on the. Control boards?? I need help with this please. Still locked up into passthru mode. Thank you
