EU2000I will run my AC, any issues?

I recently purchased a 2011 Jay Feather sport 165. I borrowed a buddies EU2000i companion model to see if it would run my A/C. It has the 26.6A plug on it, and that is what I used to connect my TT to. It ran the AC and refrigerator. My A/C is labeled Coleman Mach, model# 48253A866. My refrigerator is a Norcold model # N512UL. The AC would lag for a few seconds, but ran fine and blew cold air. I have a few questions. Will I damage my A/C or anything else by using this set up? I didn't even thing to try it, but would the 13.3A plug run my set up? I have a 16.5' TT with a smaller v6 truck. Weight and space is a commodity. It would be absolutely perfect to just use the one EU2000i. I have access to a 3000 Honda to try as well but it is very heavy and would rather just haul the one 2000. Any one have any input or experience trying this? I would only be running the A/C a few hours a day and at the very most 10 days a year, more like 2-5.

I think you only have 26.6 amps if you parallel with another eu2000. Otherwise its 13.3 amp.

2000 watts at 120 volts is 16.6 amps. You might get up to 18 or 20 At a surge peake.

The appropriate size is really based on the size of the A/C unit and how many amps it pulls at start up. The initial amperage demand will peak when the compressor first starts.

Most of the treads I Have read here on JOF suggests that the 2000 w generator will be under sized for running a typical AC unit.

The 2000w gen set May in fact start and run the AC unit, but will be under heavy load and not much capacity left for anything else.

Folks have minimize that momentary demand by adding a " hard start capacitor"

I will say possibly, but maybe not always. I think if it is really hot, it may not be able to start. I had a 2000i that would not start my AC. I was looking at getting the companion 2000, but then ran across a better cheaper solution. I bought a champion 2800w(3100w peak) from Costco. It was on sale a in March for $699. It's now $799. It runs my 15k AC and everything else in the trailer. I ran my Honda and the champion at the same time. As far as sound goes, you can't tell the difference. The only difference I don't like is the champion is heavy, but it has wheels, so it's not bad. I sold my Honda a day after I listed it. Really glad I made the purchase. Two guys at my work also have purchased the champion.

Glad to hear that Champion worked out for you. I spent about $1k on my EU2000i Companion and while I love it, I would have gone for the Champion at $300 less and 50% more power.

If you are truly getting 26 amps from one genset then you are okay . Typical AC units need about 17 or so amps to start then settle down to about 13 to keep running. Newer madels maybe a little less. Microwave is also a large startup consumer. I'm not familiar with these types of gensets. If as the other poster says you are only getting 13amps on a single unit, then you're gonna burn something up. Your owners manual should have a breakdown of which appliance draws how much amps. See what you use and add them up. And double check just how many amps one genset provides.

One EU2000 and U're only getting 13.3 amps, which might on a good day run the AC. The 30amp plug will only pull the juice that is being generated. You are risking and I would risk saying "early failure" of your AC buy running it on an underpowered generator. What might work does not mean it is recommended. In this case you need to listen to those of us who have experience.,

Some additional facts you need to be aware of. A Honda EU2000i is rated 2000 watts/16.7 amps for short duration (<30 minutes). Continuous rating is 1600 watts/13.3 amps.

This generator will start many 13,500 BTU air conditions from a cold start. The problem will arise when it is cycling and the pressures have not completely equalized before a re-start is done.

Simple answer is a Honda EU2000i is pushing its limits to run a 13,500 BTU air conditioner. NOT recommended.

IF your batteries are down the converter will be running at full power then the fridge + the A/C unit.. you may find over time you will damage the A/C unit.. from low voltage.
