Today I spent the first half of my day installing a Victron 12v/3000va/2x120 in my 2017 Thor Outlaw 38RE and the second half of the day trying to get it to work properly, to no avail. I am hoping someone smarter than I am can assist. Here is the situation.
Installed the Multiplus-II and configured it to run with my 600Ah of Dakota lithiums, no issue there. It will roll from inverting, charging, etc; no issue there. The issue comes into play when I am running on generator power (which is an Onan gas 5500). The Multiplus is only using one of the 30a legs off the generator for power. When running the two rooftop AC units and the power on the AC-IN side gets to about 3900W it trips the circuit breaker on the generator(basically when supply is less than the demand). The odd part is that the breaker it is tripping is not the 30a that is running the AC units. It is tripping the opposite leg. I have trips moving the AC units to separate circuits on the circuit breaker panel in the coach and no change. I can see that both the L1 and L2 legs have available power but it is only using one 30a. It will show only L1 on the AC-IN side and L1 & L2 on the AC-OUT side.
I googled the crap out of the issue and found that many have had success disabling the "Ground Relay" feature in the VictronConnect app; did that and no change. I have tried replacing the 2 30A breakers on the generator thinking maybe I had weak breakers; no change. I have tried flipping the legs around the MP and it trips the opposite breaker.
I am at a total loss here. Basically, I went from having 2 x 30a while running on the generator to have only one 30a circuit available. I've gone thru all the settings in VictronConnect and VEConnect3 but see nothing that would control the L1 / L2 legs on the AC-IN side.
Suggestions? I am open to anything at this point.
