Hard start cap

HI folks
My 5ver has the new dometic 15k hp ac. Supposedly better cooling with less energy use. I'm wondering if anyone with a similar unit has installed a supco cap and tried the ac on a genset. I have the Yamaha 2400is which would run my 13,5k 8 year old dometic without the cap. Just wondering.

No expert on the RV a/c systems, but I have worked on residential and light commercial for almost 30 years. It all boils down to amps/watts/volts. I would assume the max starting amps on that compressor would be about 25 amps(LRA). Running amps(FLA) would be around 8-10 amps(kinda estimate) based on experience. The generator should put out about 20 amps 120v. I assume at peak output. The math is there and I am assuming you have tried and are having trouble? The start assist kit won't hurt unless the compressor manufacturer doesn't recommend (some scrolls do not). Be mindful of high load and peak use start up times. IMHO you are asking a lot of a small generator.
