Best Generator to Run an L21

byrdmeister · Dec 1, 2013

Assuming that you might have to run the A/C and have a few lights on, what would be a sufficient size generator to adequately meet the needs of this size trailer. Also, what are your best experiences with brand, model, etc.

P.S.-I found how to do a search after posting this and I have been reading. However, many of the posts are from several years ago and maybe there is new light to be shed on the subject!

The size required to run all of your lights, fans and pumps is not significant. Most 800/1000w inverter/generator can do that with no problem.
However,,,,,, If you want to run an A/C unit it will need to be be much larger output.
How much you say? Depends on the size of the A/C compressor motor and the draw of current. I have a 4000w from my business, but have no need for an A/C while camping so have never tried it.
There are many good brands of small inverters, and others will give input.
I have a 900w honeywell that is quiet and works well, but it will not run a A/C.

I have added the information found on the A/C. The model I have would be the brisk air that are listed on the left. Can you make heads or tails of this info. enough to direct on size of generator needed?
Thanks,

Assuming your AC is 13,500 BTU, according to your chart you will need at least a 3.5 KW(3500 watt) generator. You have to remember that the AC compressor starts under load and requires a large surge of electric for just a moment then settles back to a much lesser power requirement.

I would go with two Honda 2000i generators with the parallel kit so you will have up to 4000 watt SURGE and 27 amps constant.
When it comes to generators these can't be beat. There are none quieter and Honda reliability is hard to beat.
Being these are inverter generators they have the ability to idle down when the load is low and they only use about a cup of fuel per hour each at a 50% load.
If you only need ac voltage but not air conditioning you can use just one.
I find used pairs on craigslist for under $2000 all of the time here in Phoenix area.
Google these.
