I have a 2019 Heartland Fuel 335 Toy Hauler. I just installed my multiplus 3000. My trailer is 50 amp. So I installed a manual transfer switch to be able to feed phase 1 or 2. Attached is a diagram of my exact setup.
The problem is that now when I turn on one of my AC's on shore power, it trips either one of the 30 amp breakers on my Onan 5500 watt generator. Prior to installing the inverter, I could run both AC units of that generator at the same time. Now, I can't run one.
I tested the 120VAC coming out of the generator and going all the way to my 50 amp breaker. So why would it not run the AC on 120VAC?
