If generator runs fine without the engine running but shuts down in 30-45 minutes with the engine running = BAD BATTERY.
Meter might say 12. Might pass the little silver box’s so called load test. Might be less than one year old. Drained completely dead and recharged is a common thing for house batteries. Like at the dealership. Chassis’s battery is more isolated when not in use so they don’t fail as often.
Just generator on - 120 volts to converter - 13.6volts from converter to house and house batteries with plenty of amps to maintain the batteries for the generator and run the house systems
With the engine running the alternator now charges the house battery, the chassis battery, runs the vehicle 12 volt system and the generator draws from the house battery. I have seen many many cases where the battery is the problem.
