Just got my EU2000 to run my A/C. The unit is a Dometic Penguin 11,000 BTU, model 600312.331.
The Honda runs it just fine in econo mode here at sea level, but there is a surge when the compressor cycles on. The Honda bogs briefly before kicking up the RPMs. The A/C unit stalls for the duration of the bog buts comes back. The A/C cycles on and off through the afternoon.
This probably isn't good for the A/C unit. I recall reading about a soft-start capacitor to help ease the surge. I tried searching, but this ain't google.
Thanks in advance for any help,
Cheers,
Greg

For my previous camper I had been carrying two EU2000i generators in order to run the A/C. After I installed a Supco SPP6E Hard Start Capacitor in my Brisk Air 11,000 btu, I could run on one genny at nine thousand feet. At high altitudes I had to take other loads off line, even the charger.
My new rig has a 9000btu Polar Cub, which is plenty for a TC, and one Honda 2000 has no problem running it.

Although this doesn't answer your question, why not just set the thermostat to it's lowest setting to prevent cycling?
Temporary solution anyway...

Temporary solution anyway... Possibility of freezing up, as well as being uncomfortably cool.
Supco SPP6E, $30

There are 3 fan settings -- High, Med & Low -- and what appears to be a thermostat. The thermostat on the unit was already on low, and yet the unit still cycled in all three fan settings. It was about 66 degrees in the camper. Maybe it would not cycle if it were indeed warmer, but I didn't think the thermostat actually considered the temperature
A 7000 BTU unit is not out of the question, but I am willing to try the capacitor first. A second EU2000i is not an option. I resent carrying one generator, even as small as it is. I'd really rather replace the A/C with another FanTastic fan.
Thanks for the link, ya'll!

UPDATE:
I installed the Supco SPP6E today. It is just a little better than without. Most of the time it won't trip the Honda's overload, but it still bogs when the compressor comes on.
The 11,000 BTU is a wee bit too large for a single EU2000i on Eco-mode at sea level. Sure, it runs in normal non-eco-mode, but the Honda ain't too quiet then.
Next step is to either sell the Honda and look for a Yamaha 2.4K, or get the moderately smaller 9200 BTU A/C.

gregorya,you simple have too large of a air conditioning unit for that EU2000,even with a hard start kit its still going to bog down. When the compressor kicks in it needs up to 50% more watts over the running mode.Its normal for the compressor to cycle, but not to bog down.
You would be better off getting a smaller AC unit such as a polar cub.

I think you will find of the options, the 8300 btu Polar Cub (about $650) will be the most effective. I have the heat strip, and question it's value.
The generator will cost more, and need storage space. I have one 2000 Honda.
The Fantastic fan will only move the air, not cool it. For that purpose, a WalMart 12-volt $15 fan will do the same job, and you can direct the air. I have one, and the 9200 Polar Cub.
If you decide on a Fantastic fan, I encourage you to look at the $130 SHURflo Comfort Air Fans: Gold Series. It can be used with the vent closed. I also have one of these.

I know I have too much A/C and not enough generator. I was hopeful I could do something workable.
This weekend we'll test it up in the High Desert at about 3500'. Forecast is for a comfy 85F.
As Wayne noted in his other post, one never knows what BTU rating they are getting with a Polar Cub. It's also heavier and physically larger than what I have.
{Actually, I have seen a post that matches up model number to BTUs, but darned if I can find it)
I really wanted to share the results of installing the capacitor. It helps a little, but it is no magic bullet.
I am very happy with my Fantastic Fan. It moves a lot of air, very quietly, using less power than a lightbulb. We have had one or two in every camper thus far. It has it's limits when it gets hotter outside, but we try not to go camping when and where it's that hot anyway.
The only reason we have A/C (and now a generator) is for Mrs. Just-In-Case. We are still living just fine off LPG and solar.

Folks, I would like to open the challenge on A/C's, on several points:
1 Any A/C from 7000 to 9500 is more than adiquate for a TC.
2 Any A/C from 7000 to 9500 will run from one 2000 Honda.
3 Any A/C from 7000 to 9500 will cost less than a second 2000 Honda. This is true even if you throw your 13000 in the trash bin.
4 A fan will only move air, and will not cool it other than wind chill.
5 If the Mrs. is not happy, you will not be happy.
In the three years I have had my A/C, I do not think I have used it ten times. I guess that means about $60 each time. That is not cheap, but I think I am worth it. It is there when I want it.
