Yamaha 2400 and AC
Any comments on running the A/C off a Yamaha 2400 watt generator? I live in Colorado and don't want to hurt the AC unit.. I'd rather be safe than sorry.
Thanks, Jim

Altitude will definitely affect the output. As for how much, that's hard to quantify. A 2000 watt generator has run the Dometic AC unit successfully, but that was at ETI in Chilliwack, and that's close to sea level. Some forums suggest that you can expect a 50% power output loss at 10,000 feet. I have no idea if that ratio holds true at say 5000 feet, which would be a 25% loss. They also make jets to replace the factory ones depending on the altitude you run at. Some have retrofitted with the high altitude jets to compensate.
If you wanted to be really sure about it, a 3000 watt generator would be better. Of course, it's bigger, much heavier, and more expensive. Another alternative is two smaller generators running in parallel. Again, more cost, and more equipment to carry.

In addition to Robert's post, you may wish to research hard start caps for AC units. I have no idea if you would need one though.

We easily and successfully run the AC with our Yamaha 2400, using propane through the quick connect. Missoula is about 3300 ft and where we camp is around 4000 generally.

Well there you go. Real world experience is always a good indicator. The OP didn't mention where they'll camp, but of course, much of Colorado is at least 5000 to 6000 feet up.

Yep, most of our camping is around 7500'. Great to know it works well at 4000.

You'd need the triple fuel model EF2400 to run on propane. There are also conversion kits to allow the gas only model to run on propane. If your trailer is equipped with the propane quick connect, you don't need a regulator- just a qc fitting on the generator.

We've run our AC with the Yamaha 2000 at sea level and on propane.

I'd expect that to be the case, since it's been run near sea level with the Honda 2000 that has similar power output.

Did you do anything special to the AC before you ran it? Like adding a hard start, soft start, medium start thingy?
Tonight I started my 3 year old but brand new, never been used Yamaha gas powered 2000w in preparation for a weekend of camping in NH. Would love to be able to safely run the AC, should we choose. But the wimp in me probably won't risk it.
I was surprised how quiet it was. Course I had no load on it, but I swear it was as quiet as solar!
