SoftstartRV AC control unit

Anyone on the board have experience with the soft start RV unit? Allegedly the unit controls the start and running on RV AC. AC will run on much lower amps. Demonstration I watched was use on roof ac unit. My question is if they work with Coleman basement AC?

I have installed Supco SPP6 and SPP6e on two RV rooftop ACs with good results. The SPP6e costs more but is a improved design that has a backup electronic timer to further protect the compressor vs. the basic SPP6. The cost of the units is under $ 15 and $ 25. These don't replace the Start/Run Capacitor, they install in parallel with the Run Capacitor.

If your AC is 7 years old or older, then you may also want to spend another $ 20 and replace the OEM Start/Run Capacitor at the same time, as they do slowly degrade over time.

I can't see where there would be enough incremental functionality to justify the ten times more expensive unit.

Thanks Wyatt. Yes, started reading and it fell off the point of the soft start unit issue. I was asking if anyone on this forum board had actually used one and more specific on a basement AC.

FYI, I follow AZ Expert channel as he has a lot of info on Winnie roofs, and other RV tech/repair videos and he responds. So I asked the AZ Expert on his youtube channel about it. Here is what he stated to me:

"I have not installed one on a basement A/C. They are fantastic bits of tech which do what they say they do. They seem so magical that I am not sure why manufactures don't offer them. All that being said, basement ACs don't have a lot of room in the electronics bay so they would have to be mounted externally which could be a bit difficult with most of the AC installations I've seen."

So AZ Expert states they work well on roof ACs. He is skeptical of installing one on a basement AC due to limited space and has no solution for an external mounting of the softstart RV unit. I have been on the tedious email tech support exchange with the softstart tech and they are not experts on basement ac and been no help of my questions. Will it work on Coleman basement ac? Where would I install it? I am leery of buying unit even if its super if it cannot be told by tech folks where to put it and how. As of today I have to explore it at a later date and see if anyone else has it working on a basement ac. Regards,

Yes, I purchased and installed the EasyStart Version from MircoAir and I believe it works just like the SoftStart. I installed it on my new 2020 Navion 24D and it works wonderful. When hooked to shore power at home, I can run off a 15 amp circuit with ease. My reason for installing the EasyStart is so that I can run my A/C for brief periods off my 2000 watt inverter and my 250ah of Lithium batteries. I know currently the A/C is wired outside the inverter and I am hoping to figure out how to change that, anyone out there know?

Ask the AZ Expert

I assume you have roof AC not basement AC for which I was asking. sNo person seems to think softstart or other works on RV basement AC sytems. For tech questions like yours query AZ Expert on his channel as he is good about responding and can probably answer your question.

The Coleman basement A/C has two compressors that run in stages. First one compressor starts and then after a few minutes if needed for cooling the second compressor starts. That probably makes it difficult to install a sophisticated Soft Start system. At the very least you would probably need two.

I would install two inexpensive Supco capacitors, one for each compressor and see how that works.
