AC Generator Use

Have a 201QB travel trailer with a single 13,500 BTU AC unit on the roof. My Yamaha EF2800i can not run it. AC starts and they Gen goes to overload. Anyone know what the required output in watts of the generator needs to be to run it? Does it need to be an inverter as well?

I think the initial hit is 3600 watts

Try a hard start capacitor - search the forum and you will find the info and model number for it. Very reasonably priced mod.

The dometic manual for my 13,500 btu unit states it requires a 3,500 watt generator to start the unit. That is to overcome the 29 amp surge at startup.
If your generator is rated at 2,800 watts I assume it can deliver only 23 amps at a startup surge condition.. You might be able to overcome the 6 amp difference with a soft start capacitor package as mentioned previously..
Good luck!!

My motorhome had a 4k Onan generator on it. It would pull the roof AC, microwave, etc.. I think to be safe I'd go with a 3200 - 4000 (surge) generator. Two parallel 2k generators like the Hondas or the Predators from Harbor Freight would do the job and be very portable.
