Think if you add a VFD to the fan motor it would quiet it down. Possibly at the expense of freezing up tho.

Unit does indeed reduce startup surge of the compressor, and it does run a little quieter, i.e. compressor is quieter, the fan system is still awful, so not to be used at night for sleeping.

I will be changing my Inverted circuits over to include the AC circuit, so I can run the unit off my 3000 Watt Inverter fed from my 650 AHr Lithionics Battery system. I will post more details once I have had experience running the system in boon dock mode.
Yesterday I finished modifying electrical so the AC is now powered on by either Shore Power or the Inverter. I ran the A/C unit for about 1-1/2 hrs. at full on, just see how the battery system responds to the constant load. Once the compressor kicked in the system drew 135 to 137 amp from the battery bank. (Note: Outside air temp about 78 DeF, starting air temp inside RV about 85 Deg F, set point 60 Deg F - Never reached this set point after 1-1/2 hrs of running)

I have 5 - 150 AHr Lithionics batteries in my RV so I have the potential to provide (( 150 x 5 ) x 80%) = 600 Ahrs; which means conservatively I could run the A/C under full load for 5 hrs. In practical terms I will probably only turn it on for a few hours to cool down the RV enough for sleeping; when dry camping. I have 400 watts of solar capacity; which will help augment the drain on the battery while running the AC.

Since I no longer have a generator, I use the Auxiliary Alternator to charge the battery bank; while driving or parked using High Idle option on the engine. Speaking of driving one of the nice things about running the A/C from the batteries is I can also drive and run the A/C and cool down the whole coach before I stop to camp at the end of a day’s drive!

We will never sleep with the A/C running because of the fan noise. Rather open the windows and use small table fans to cool the murphy bed space and / OR the skylight vent fans.

Just a side note about the A/C unit on the roof of the Unity MB, and all the other ones I have seen so far; all of them are painted black! The housing is absorbing sun-light and heating up the interior, where the compressor is exchanging heat from the evaporator coil. I pained my cover white to match the roof and I believe, but have no hard data, that this will help remove the heat from the evaporator coil under the cover.

I just Installed an Easy Start on my AC and now the compressor runs so quiet I can't hear it kick on. I also took Gamma1966 advice and painted my AC cover white, it should make a temperture difference. I know when I went to a white metal roof on my porch the temperature dropped 10 degrees. Anyway, all I hear now is just fan running. I hear no discernable noise difference when the compressor kicks on. I can't even tell when the compressor kicks on. The only way I would know it turned on is if I look at the voltage meter that I have plugged into one of my outlets. When the compressor kicks on the voltage drops from 123v to 119v. I like that it runs quieter but I wanted it so I can run my AC even if I only have access to a 20 amp outlet or a lower power 30 or 50 amp receptacle. Recently I was at a campground that gave me a site with a 50 amp receptacle but when I plugged in my surge protector when to power but it said low voltage  (L1) and 16 amps. My AC ran fine. I hope this PDF of my install helps someone else have an easier time than I did. I ran into trouble because the instructions lead you to believe you can use the generator for power to go through the Learn Process. That is absolutely not the case, so thankfully they have great tech support and a comprehensive document support on their web site. I've attached the documents I used for this install.


I also watched these 2 videos. The first one is an install on a unit that is very close to the one on my Unity. It just doesn't have the heat pump. So it's really the best to watch. The second video goes through more details and is just another reference.

So what prep work did you do on the AC shroud before painting and what paint did you use?

I just cleaned it very well and lightly sanded it and used Rustoleum Painter Touch, https://www.homedepot.com/p/Rust-Ole...4048/307244833, that is advertised to bond to plastic and it does. It comes in lots of colors so you could use cream, light gray, antique white, another light color if you don't want bright white. I just happened to have a bunch of cans of white that I bought at Ollie's so I went with white and I'm happy with it. It goes well with my Ultra Breeze vent covers which are white. A white AC cover definitely makes a difference, I found myself turning the thermostat up on the first trip with this EasyStart mod and I loved that I can't hear the compressor running and it stopped the quick cycling!

Reduced noise due to some sort of ramping of power to soften the step of the compressor is one thing, but claiming run-time noise would change at all is ridiculous. What exactly are you claiming - other than the placebo of feeling good about spending a bunch of time and money on something you could have done with a $30 capacitor?

I run my Coleman Mach AC from 2 Tesla modules and a Victron Multiplus 24/3000 inverter charger. I have 8.4 kwatt hours of power and 400 watts solar that charge at 18-20 amps per hour. No need for the soft start as the battery system can provide the starting amps needed.
What inverter are you using?

Please provide more info on the $30 capacitor. How would that replace the capability of the easy start?
