Honda 2000 gen starts my AC....

For more reliable starting add a hybrid inverter that will do load support.

I've run my 13.5 a/c with my Honda 2000.
Was even able to run it in Yellowstone but I only ran it for a short time to see if it would.

You might want to try running it....for a hour or more when it is hot outside....before you get too excited. Even if you are successful doing so, answer this question. Do you really want to rely (in really hot weather and/or at a remote boondocking site) on a system that is working at (or even above) it's rated specifications?

I can easily start my 13,500 BTU AC with a single Honda EU2000i as well. However, starting is not the problem. Running it for any length of time (esp. at altitude) and/or when it is hot (like above about 70 degrees) is. I have attacked this problem from many different directions and the only reasonably conclusion (for me) is to use two generators. Your experience may be different....but I really doubt it.

The Honda is smarter than....... Let's just say that it has built in safeguards that keep it from destroying itself. Running air conditioners is a hit or miss thing at best. I am three for five of my last few units at various temperatures and elevations. I only do it for a temporary cool down while traveling, not for day after day.

If you comb through the archives you will find posts from numerous RVers routinely running a 13,500 BTU air conditioner with the eu2000i, more often than not a Dometic Brisk Air. Success with other brands is low. You'll also read that either the air conditioner will burn up from low voltage, even though it's 115 or higher, or the generator will burn up, even though the running power draw is comfortably under the generator's maximum continuous rating (with the Brisk Air). For success you definitely have to manage the AC loads, and don't rely on it at higher altitudes. Best to monitor the running voltage. If it's at or near 120, you're IMO not abusing the air conditioner or the generator. Just have to see what works for you.

Takes about 3,200 watts to tun an A/C unit.

where in the word did you get that number ?

12.5 amps times 120v, roughly 1800w to run an A/C unit

3200w would be about 26 amps at 120v

Anyone have any advice on this??

Try it at much higher elevation when outside ambient temps are beyond the mid 80s and you'll be sorely disappointed. :(

As mentioned here many times, doing this long term won't be good for your gen. For that you should have 2.

What is your objective?
