Genset issue
Gen is shutting itself down. It worked fine for a trip and then upon returning home it shuts down after running a couple minutes it shuts down and blinks a code 12 that reads: "Inverter overvoltag...

Just to bump this up again, I have a question. Is it possible since the generator is being exercised with no load, is it going over the voltage specs.
I don't think so. From my experience, if a generator is over-volting, it's either dirty slip rings or the Voltage Regulator (VR). AND, it's possible dirty connections could cause the VR to think the slip rings are dirty.
Mine runs about 132 volts until I place a load on it. So I guess I am suggesting the OP start the genny and turn on some small loads like fans, lights and maybe the fridge on AC.
Classic symptom of a bad regulator but...check the slip ring resistance and clean all the connectors with good contact spray. IMO.
I know you are supposed to let the genny warm up before placing loads on it, but most start up with at least the converter being on. It might be a simple experiment.
Warm up isn't really necessary for most generators. The engine spins up to speed, the control system has a delay in it to prevent applying the voltage to any load after it measures the AC voltage, 108-130V, and the Hz, 58Hz-62Hz, if outside these ranges, it's suppose to shut down. If it's outside these ranges and doesn't shut down, it's almost always the VR.
