2a/c residential Refer 5500 Onan. All 3 start/run then soon after Ginny breaker trips loss of power when using gin
Micro-Air ASY-364-X20-IP EasyStart 364 Air Conditioner Soft Starter - With Installation Kit
I have 2a/c and residential refer in 5th wheel. When using 5500 watt generator power my refer automatically starts and one a/c is fine. However, 2nd a/c will start and run, then shortly afterwards, the generator breaker trips. It was my understanding that my generator was big enough to handle this load. The generator doesn’t bog down when 2nd a/c starts but it isn’t supplying enough power as your requirements suggest. I have been wanting to install the soft starts on my a/c units. Having read your description, I see that I don’t have a big enough generator. Just how big of a generator do I need?

Before installing a larger generator to meet the power needs of your RV, I would first check the generator circuit breakers, checked with an accurate ammeter, or have an electrician do it. The breaker(s) as you should have two, might be faulty and tripping too soon. And not the first time a circuit breaker was faulty. And too, if having an electrician check the power distribution, the refrigerator and one AC should be on the 30 amp circuit breaker and the second AC on the other 20 amp or second 30 amp circuit breaker of the generator. Now it might not be possible to power everything in the RV when running 2 AC's and a refrigerator, to include an electric water heater, and convection or microwave oven, induction cooktop all at the same time with only an 5500 Onan. Managing the power distribution in your RV to meet your usage might solve tripping breakers before installing a larger generator. That 5500 Onan is only going to supply 45 amps at best. Not the 50 or 60 amps a 30 and 20 or second 30 amp breakers would allow through. If my 4000 Onan can start and run two 13,500 BTU AC's each cycling and staring as needed, without soft start or tripping the circuit breaker, a 5500 certainly should too.
