I wonder too if the compressor is just seizing a little....

I guess on shore power it works just fine? You would think it would pop the breaker in the RV if it was drawing over the RV breaker amps at start.

shore power?

Something isn't adding up here.
So, you plug the trailer into your shore power right then and there, and the A/C runs properly or not? Y/N
The generators breaker trips? Which breaker, the 30A twist-lock or the 25A duplex receptacle with adapters / pigtail?
Do you know how to isolate the converter?

The trailer was plugged into shore line when I was getting it road worthy and it worked just fine. Fast forward a few months after sitting in a storage yard. I connect it to brand new genie....no go.

The genie overload pops no matter what connector I use. The most recent is the 30A twist lock. As for isolating the converter, I am an electrical idiot.

If the breaker is popping within 30-45 seconds, you need a new capacitor for the compressor most likely. Replace it, you can add a hard start too if you want, and you'll be able to start it no problem. When they are that old, it's not uncommon to need to replace them. I rebuilt a 15 year old RV AC not long ago that would do the same thing until the cap was replaced.

Thank you. I will look into getting items.

I concur your starting capacitor is probably worn out, happens all the time. The symptom would be high starting current that overloads the generator. You can get a replacement cap for a few bucks and give it a try.

I just installed a Micro-Air EasyStart 384 this past weekend on my 13,500 Dometic Penguin II that came stock with a start capacitor installed. I was able to run it off one EU2000i not in ECO mode, but the voltage dropped to 60 VAC when the compressor started. With two EU2000i's in parallel in ECO it would start, but a minimum voltage of 60 VAC once again. I measured the peak current at around 43 amps before installation of the EasyStart.

After installation (which was pretty easy) my starting current has dropped to 14.7 amps! I can now run fully off one generator in ECO mode, although the voltage does dip to 82 volts until the generator speeds up. In normal mode, 1 volt drop. With two EU2000i's in parallel in ECO, only 1 volt drop again.

So I'm pretty pleased with the EasyStart, glad I found them!
