Does anyone have any input on the soft start addition for you a/c and does it work?

Hi Mike,
A quick Google showed the Micro-Air 364 for $280.  That one is good for 36,000 btu's, so it's somewhat overkill for a 15,000 BTU dometic.  Here's a link:

One forum mentioned that the Dometic brand unit was $600.  That's really an unnecessary expense as a soft start device is pretty generic.  If there were 20,000 btu soft start devices, they might likely cost less and be a bit smaller.  I'll look around.

Also note, that the device needs to be installed inside the A/C, and many folks might want an electrician to do it.  But there is a very nice, complete installation manual for installing it in a Dometic A/C, with lots of photos.  Not a lot of wires.  Basically it replaces the start capacitor with electronics which ramps up slowly, reducing start currrent by 65-75%.

Easy start is the same as the OEM setup, capacitor and Ptcr. Why replace what you have with something that does the same thing?

Less like cap, more like VFD. No need on shore power. If you're running an auto throttle gen, there's a minor brown out each time the compressor starts while the gen spins up. Soft start helps smooth that out.
My ac is a $250 window unit, gen is a Honda eu2200. No soft start so an experiment in progress. 
So far, so good. Mrs Tom will not be happy though if my experiment yeilds results in the middle of the night... 🙂

Don't know what a VFD is or how it works, but have the same gen. My ac always started just fine and the gen ramped up immediately. Now, I don't remember if the ac  has a current or potential relay or the ptc. Good luck with the experiment
