Generator size for a 15,000 btu a/c question

RSD559 must have had issues with his Honda EU3000is. Mine will run my 15000 ac with no problem. It ramps up when it initially hits the load of starting but then cuts back to a little above an idle. I don't know how many camping friends you have now but if you buy a Champion generator you are standing the chance of loosing them. Obnoxiously loud. Spend a little extra money and get a quality generator. Honda, Yamaha.If your going to put everything that RSD559 is suggesting you might as well have the electric company install you a pole.

A 4400 will do it. The issue may be how may other things do you wish to run while the AC is running. When the compressor kicks in the surge requirement is double. On my wife's grooming van we ran an 8500. It would run everything all at once. At times it seemed like overkill but, we ran lights, a dryer, the roof AC, a stereo, clippers, etc..

5500 is more than enough power but heavy, noisy and a gas hog.

3000 can pretty reliably start an air/con and you can go as low as 2000-2400 in some cases (2000 you likely need to add a soft start to the air/con and it still may have difficulty at times)

Honda's, Yamaha are the premium ones, Champion, black and decker, predator are also seen frequently. 3000 watts are enough usually.

yeah, i wouldn't camp with this generator around anyone. was going to test run on our back 40 acres...

Generators can be pretty pricey. You might want to try one out by renting it for a day. My Champion fires up my 15k A/C without even a whimper. My old Honda EU3000is wouldn't run my 13.6k A/C in my old trailer without a hard start kit in it. You might consider putting in a Microair Easy Start for your A/C. That would run you about $300. But you could run your rig with a smaller generator, saving you even more money. I've seen posts from folks running 13.6k A/C units with 2000 watt generators. I don't know about the 15k units. My brother-in-law has a Champion 2000 watt generator. I'll have to try it after I get my Easy Start and get it installed.
