Little generator that can

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!

  • Prediction for today 102f
    I just finished breakfast, weather app says outside temp 78
    Thermometer inside 78

    first thing 8-9am fire up the genny have breakfast start charging the batteries


    We don't boondock in the summer because it's too hot. This was just a test at the ranch to see what the little 2400 could do.
  • I finally built 30A service out of the garage yesterday. Running the coach on a single compressor just wasn't cutting it at 106

    first thing 8-9am fire up the genny have breakfast start charging the batteries

    by 10am if not before, i turn on the A/C

    i know from experience, if i wait until its near or over 100
    that i can't do anything but the A/C, and everything else is entirely Solar and Batteries
