EU2000i and AC
The '77 Argosy I am buying has AC - amp draw unknown to me at this time. I am thinking that I will buy a Honda eu2000i generator. BUT... I think the AC is the highest draw and wanted to calibrate for loads before buying a generator (or generators).
Anybody hazard a guess as to the amp draw of AC running on 120V? I think I can figure out the rest of the amp load, but need AC help.
Thanks.

It is the startup that needs all the wattage. A 3000i will do it or two 2000i connected togeather.

I tried to use my EU200i to run the AC on our Caravel once. When the compressor kicked in the poor generator almost did a snap roll in the driveway. It was not happy. I am not sure what the power requirements are for the AC but it was obviously too much the little Honda.

The Honda will run our 12,000 btu roof air--barely. The generator grunts and groans, the a/c compressor does the same, thent he compressor leaps to life, and the generator relaxes a bit. It is not recommended because of the chance of burning up the compressor, generator, or both. Everyone has pretty much agreed a single 3000 is too awkward to schlep around, and 2 2000's will give you a total of 4000 watts for about the same money as a single 3000. It's easier to tote around a pair of 2000's,one at a time, than lugging the hernia-producing 3000 by yourself.

We use two EU2000i running in parallel and it handles both the air and other smaller electrical draws with no problem. As was reported earlier, the startup of the A/C is the major draw.

Most roof A/C units pull about 12 amps for the compressor and another 4-5 for the blower motor (depending on the ambient temps). That is NOT counting compressor start-up....which can draw a momentary 25-30 amps!
Yamaha states that their EF2400iS will run a 13.5K roof air, and there are several folks on these Forums that have done so successfully with said unit.

That extra 400 watts helps. Really.

Thank you all. I thought the little Honda was not up to the task, it would probably be running at 3/4 speed and making more noise as well. I thought of dual Hondas, which has a lot of advantages, but the Yamaha EF2800i would do the job with less work, and it weighs only 20 lbs more - and less than my outboard engine.
Obviously need to study a bit more.
Thanks again.

Well, almost everybody.
Mike there are reams of pages on this subject and everything else you may ask about Generators; their use, their weight, Honda vs Yamaha, how to put wheels on the 3000 on the cheap, Lots of facts, lots of opinions.
Click on the link below for a bunch of generator threads found with a search.

Mike,
Be careful about which Yami you pick. The EF280i is a construction site type rig....very noisy when compared to either the EF2400iS of the Hondas.

We use a Yamaha 2400is with a 13.5BTU and it works very well. It has enough power to run the AC, TV (27" Bravia), surround sound and satellite receiver. I usually turn the fridge to gas and avoid any other power drains. This little gen is very quiet, easy to handle (I think about 68#), and has been flawless in it's operation.
Best of luck with your genset search, and enjoy your day!
