A/C runs for 10 seconds and shuts down when running Generator on the road?
I have a 2016 SunStar 35F. Still under warranty.
Driving in hot weather, I'm taking the advise of those on this forum to use coaches A/C vs. chassis A/C. However, ever time I start Generator, turn on living room A/C it only stays on for maybe 5 seconds before tripping fuse? No other load is being used?
I was under the impression that the inverter was supposed to prioritize components even if their was excess amperage needed?
Anyone have an idea what the issue is? Love to keep my cool in the drivers seat and fix while on trip and 800 miles from dealer?

Yes, in bedroom. I will test that tomorrow once we disconnect from shore power and head out. Will respond tomorrow as soon as I do.

Is the circuit breaker that trips , on the gen set , the inverter, or the main A/C breaker in the 120 volt panel?
Because of the power draw , most RV roof A/C s , aren't wired to the inverter.

As someone else asked, are we talking about the breaker on the genset?
If the 2nd unit does the same thing, have a look at the transfer switch and wiring. The difference between shore power and genset power (to the A/C) is the relay contacts in the transfer switch (and the wiring back to the genset).

It worked this am, I'll have it checked out at dealer. Seems like the issue might be with the Powerline EMS? Not sure why it was ok thus am, but I'll take it.

I'm pretty sure in hot weather the driver is most comfy if you use the chassis AC. In our gasser dash AC keeps the area around the driver and behind a few feet pretty comfortable.

Many AC units will start the fan and compressor at the same time, causing a starting load for both. This trips breakers and triggers shut-down response in the control boards.
Try leaving the AC fan on and letting the compressor cycle on/off as needed.
