I have a 10 year old Yamaha 2400is that I use for boondocking. I wanted to see just how much it could take. Living in the Mojave, we are experiencing a big heat wave. I hooked up the genny to the trailer this morning when the outside temp was 106, humidity was 11% and the inside was 102. I'm at 3550 MSL elevation. The Genny has sea level jet in it which is good to 4000 MSL as I understand.
The AC fired off as it usually does with just a little additional rumble from the genny. Everything else electrical was off in the trailer. Initial running amps were about 12 for compressor and fan combined.
As the heat built up in the compressor the amps slowly climbed to 16.9 amps at 122v. Theoretically, this is 2062 watts which exceeds the running output for the 2400.
I let it run for about 40 minutes and it had dropped the inside temp by 10 degrees to 92.
It did not reach a temp where it went through a restart, so I don't know how that would have gone, but it has never been a problem before.
That little generator still CAN!
