Portable A/C run off Honda 2000i generator

[Wileymannow]

I have a 1998 Larson with, I believe, a 12,500 btu a/c, and on shore power it chills the cabin! I have purchased one of the new Yamaha 2000 generators (side by side comparison's say they're better than the honda's.) Powered up, plugged it in using the pigtail adapter for shorepower... AC cut off and wouldn't run... Is the generator producing enough juice to power the AC?

thoughts?

Sounds like the surge start-up current required by the AC may be greater than the max available from the generator. Our 16000 BTU AC requires only 5.5 amps to run, but 16.5 to start.

you'd have to figure out how many amps it draws. your 2000w inverter will put out around 15 amps. half your dock power. was everything else 100% off when you tried? (battery charger, all outlets etc)

That sounds too low of draw for a 16,000btu - ours draws 14A running. What model is it?

Just checked the documentation. It's a Webasto "Blue Cool Classic" CPAC 16000. Start-up current at 230 V is 14.4 Amps and Running current is 5.5 Amps.

AH! 230V. Missed that. Nevermind....

it will run the AC, but not start it without a start capacitor or a dometic soft start

My fault - should have been more specific in original post. I forget that this is not a UK based Forum; hence electrics are generally a different voltage.

Back to the CO detector, "home" units may go off at ANY trace of CO, while marine units have the smarts to recognize when a random whiff of CO has come and gone. I actually made this mistake once, and can confirm that the home unit did alarm apparently randomly, usually in the middle of the night, even with no engine running anywhere nearby.

A 2000 watt honda will only JUST start a 6700 btu unit with the addition of a boost capicator.

Maybe if you get a big enough auto switching inverter charger MAYBE it will go and switch fast enough to not stop.
