Air Conditioning and the Honda EU2000i
FINALLY an absolute solution to the dilema. I've been working on this A LONG time and have start capacitored and fan delayed myself to distraction and up here at 6000 feet just could not get my Honda 2000 generator to consistently start my A/C unit. It usually would start it the first time, but eventually the head pressure on the compressor during restart would overload. The locked rotor amps on my Dometic was like 47 amps in the spec. manual.
I was surfin YOUTUBE and watching a little piece by the Wynn's (Gone with the Wynn's) and they made a brief mention of the "soft start microporcessor device" made by MicroAir in Pennsylvania that claims they can reduce starting amp draw by 70%.
Voila, I ordered (not cheap) their EasyStart 3T Model 364, and installed it today (only 4 wires).
Now the A/C starts VERY Easily (the Eco mode barely comes out of operation) and I can even run most of the other stuff in the camper without even thinking about it.
The tech support is unbelievably good, they even sent me a specific diagram of exactly how to wire the unit on my specific Dometic model.
No more lugging around 2 generators just to start the AC unit.
Might be an idea for those that want to use their AC and not lug down their generator or carry a big genny or two, I think it should work fine on a large variety of AC's and gennys'
I am impressed to say the least.

Could you tell us what size A/C unit you are using this with? Also could tell a little more about wiring it?

Thanks for the idea for a modification.
Every time I see an idea I like I can picture the bux flying out of my wallet...
Here are the links I found for the product:

@ Garbonz - your post sounded as if you might have tried other capacitors before this one. If so, which ones? I just installed the Supco SPP6 and a fan delay @ 9 sec and did notice an improvement over stock setup. It was a simple 2 wire but would be interested if this one is even better (some mixed reviews on the internet about the SPP6). I'm running a Coleman-Mach 15k.
Thanks!

I was looking at the 3T soft starter from MicroAir and on the installation there's a note that you have to change to a relay, do you have any info on that.

Oh Boy Lots of good questions here, and I would mostly direct you to the Micro Air web site and their tech support.
I don't think you need anything other than the device they have that I mentioned which is rated for more than anything in the RV world. They are not exclusively an RV outfit but have a variety of applications so some of the information on relays and such are for complex devices.
I have a 9K BTU dometic, but I think this device will work on anything you got. I don't know if it will definitely work on a 15K RV AC with the honda 200i, since I havn't tested that, but I wouldn't be suprized if it did.
In my experiance the 2000i bogged down horribly (with a dometic hard start capacitor) if it started at all and with this device installed it barely came up out of eco mode. I should put my loop meter on the feed to see what it actually is drawing on start up, but it certainly is WAY less than the 2000i can handle, and remember I am at over 6000ft and running propane so I am depowered by 10% or more.
The wiring is 4 wires and replaces the PCTR and Start capacitor. Here is the specific wiring diagram they sent me based on the manual that I scaned and sent them. It was a piece of cake and took less than an hour.
Hope this answered some of your questions.

Here's the link: Most of the video is on the use of off grid solar and batteries for Air Conditioning, but they mention the soft start product, but they did not actually use try it yet.

Donno, but they will, give them a call or Email. They seem to stay up all night and answer questions.
