Eliminate Low-Power Start-Up Issues For Your RV A/C.

Why SoftStartRV?

Benefits you’ll enjoy after installing a SoftStartRV:

SoftStartRV eliminates low-power RV A/C start-up problems for any RV AC unit on any rig.
It’s up to 52% smaller than any other soft start, so it fits in the tight, very limited space of new smaller rooftop RV A/C units.
Having one installed ensures your RV stays cool – or warm – during those extreme weather days.

  • Start and run 2 A/Cs on 30-amp (1 SoftStartRV per A/C).

  • Start an RV A/C with a small generator (e.g. Honda 2200).

  • Start an RV A/C whether boondocking or moochdocking.

  • Waterproof enclosure – an industry exclusive!

  • Free install kit with screws, connectors, wire ties, etc.

  • Free online install videos, guides and directions.

  • 3 LEDs show status: Start, Run/Protect and Self-Test

A Game Changer!

-Bobby M. March 17, 2020

Works Great.

I was dubious as to how this product would work, especially considering the price. I have to say the sellers video and specific instructions for each make and model a/c made the install a piece of cake. This thing really works — you can’t hardly hear the compressor when it kicks in. Very quite and seems to work perfect with my light weight 2200 watt generator. Highly recommend.

Install with care and you will be rewarded

If you take your time and follow the instructions this is relatively easy to install and it works great! It really has solved my Airstreams AC problem of tripping the circuit all the time.

The unit works as described.

I added the SoftStartRV SSRV3T unit basically so I could stop for lunch or rest while traveling and be able to run the air conditioning. After adding the unit to my travel trailer air conditioner, my little Honda 2200i handles it perfectly. Installation was easy and the installation instructions online made it relativity simple to install. I would recommend this to anyone that needs to be able to run air conditioning on a small generator for any reason. Great product!

- Amazon Customer, United States on July 31, 2020

Works as advertised

Works so well you wonder if it’s working!

-Monte A MCKENZIE, United States on April 15, 2020

Took a little longer to install, but will save in energy costs

Using this for a Grand Design RV. On one occasion before installing, we blew out a fuse. Had trouble running anything when the AC was on. Never know when the AC would start up. Afraid we might blow another fuse or worse.

Took my husband about twice as long as advertised to install. He is very handy, although he had to contact tech support. They were great. Highly recommended.

- Bonnie Smith, United States on September 14, 2020

Works great!!!

Installed the SoftStart on my breeze ll air conditioner on my RV in about 1 hour. Upon startup, the unit was starting quieter. I was running my RV power using a 15 amp 120vac adaptor for my 50amp power cord. The AC unit started perfectly. I am very pleased with this product and would recommend to anyone with an RV.

- Jerry, United States on April 29, 2020

Best tech-support I ever had

The product works great and the tech support was amazing!

- Robert, United States on August 24, 2020

Worth it.

Works just as described. My 2200 watt generator ran the AC fine. My 3000 watt generator can run AC, microwave and everything else at the same time now and hardly even revs up.

- Thebronz, United States on May 11, 2020

Support was wonderful

I first mis-wired the unit. The instructions for my type of air conditioner were unclear. Opened up a support ticket and sent pictures. Literally within the hour tech support called and left a message on what we had done wrong. All’s well that ends well. Tech support is super and the product is doing just what it says it will do. VERY HAPPY CAMPER.

- James P. Prohs, United States on August 13, 2020

I can use my Honda 2000 generator.

Works as advertised, glad I bought it.

- Amazon Customer, United States on April 24, 2020

Works as Designed!!!

Easy to install and worked without a flaw. Contacted tech support with a question and they called me in a matter of minutes and followed up with an email.

Amazing device. I had tried a hard start capacitor for my RV AC, and it either did not help, or made things worse. I was trying to avoid spending the $300 on this kind of device, because I thought I could find a cheaper solution.. but there is not one, and this device is amazing. I had all kinds of problems starting my RV AC, it would make my 3000W inverter shut off on overload, with a spike over 6000W trying to start. I would sometime come on after the inverter reset, but still at high starting amps. The Yamaha 2400IS would struggle and most times start it, but it was not a for sure thing it would work.. last RV trip it was 95 out, and very frustrating to get the AC to work… so I finally decided to give this a try, despite the cost I wanted to have ability to use AC on really hot days when camping, and not push limits of generator or inverter to get it done… I was skeptical this could work a well as advertised.. but IT WORKS, and better than expected. There was no current spike whatsoever getting the compressor to start, it peaked at running amps, never went over 1200 watts, I tried several starts, and everyone was impressive. I’m really happy with this device, frankly it should be standard equipment on all RV ACs, it’s amazing technology that works as advertised.

- mrfixit, United States on August 4, 2020

Should’ve installed sooner

Cool at the camp after this easy upgrade! Great customer service and support. I’m glad I bought this instead of another generator.

- AC, United States on July 31, 2020

It works sooooo well

It eliminated ALL the startup surge . Works as described.

- Austin William McCormick, United States on June 25, 2020

Great product with good installation instructions.

This shipped immediately and delivered in 2 days. Install was fairly straight forward. I have a Coleman Mach series unit and the are two possibilities for the start cap wiring…had to figure out what was really in the unit. Install took a little over an hour. It’s too cold right now to give it a test run, but I don’t foresee any problems.

- healthythiker, United States on March 14, 2020

Works as stated.

I need something to help reduce the load on my generator, I converted my RV from 30 amp to a 50 amp, shore line only, I still have a 4.0 generator for dry camping, I installed this unit and now I’m having no problems dry camping. Big thanks…

- Bo, United States on July 27, 2020

Great Product and Great Customer Support

I purchased this to be able to run my Lance travel trailer air conditioner using my Yamaha generator. I live at 7400 feet in Colorado and often camp at even higher altitudes, and the Yamaha balked at the start-up loads of the air conditioner. I installed the SoftStartRV without any problems (I did call Brian at SoftStartRV support once–he returned my call immediately and gave great guidance). Now my generator handles the air conditioner easily! No more hot nights in my trailer wishing I could run the air! Great product and great customer support.

- Kindle Customer, United States on May 7, 2020

Great Product

This soft-start does what it claims. I couldn’t run my A/C on a 2200 Honda until I installed this, and now it starts and runs perfectly and has a quieter startup.

- David Shore, United States on June 14, 2020

Works like a dream

It took a bit of work to match up all the wires. Like measuring, I checked the wires 5 times and then cut. My generator runs like there is no AC coming on at all. Even runs it on Econ more. Of course, it’s on a tiny AC unit in an Airstream Basecamp, but it wouldn’t run it before. Great purchase!

- Dave J. Kelley, United States on June 6, 2020

Works as intended.

First of all this is a great soft start and works well for me so far. I had bought a Coleman mack 15 rv ac unit and picked this up to install before tossing it in the motorhome. It didn’t come with any decent install directions but they had videos on their website which were not exactly the best so in the end I would say I was 98 percent positive I had hooked it up correctly and was happy when I turned it on and it was working as intended..lol. the little green light will turn your AC green in the dark which is kinda cool I guess to have a green glowing ac box. I mostly got this due to the fact I went full time motorhome life about a year ago and usually will plug I to 15 amp which with my old ac unit it would pop breakers with just the ac at times if say someone inside turned something on that was on the same circuit. I was having issues having to much power draw basically so with this installed I haven’t tried a breaker once and I’ll have a tv, PC, ac, cam, weather station, blender, lights going at the same time on a 15amp plug with no issues. Great product and I feel safe leaving my dog in the motorhome while I’m at work in AZ heat knowing it’s not going to trip breakers and my AC turn off (she has a dog door and I have a camera and weather station with motion and what not so I can remotely check temps if I’m not home).

Run your rooftop AC with a generator

STEP 3: Just do it you won’t be disappointed.

I have a Champion 3400 Dual Fuel Inverter Generator and a 13,500 btu AC unit on my camper. The generator wouldn’t run the AC unit. It would always fault out.
Installed 2 others, they didn’t work
Installed this one, the generator runs just over idle in ECO mode while still remaining quite. Best purchase ever for the camper. Now I can run my rooftop on a 20 amp plug when needed (with a short cord of course) but still when your in a pinch and need cold air in Florida this helps.
It was expensive but it was worth it. The install took 20 mins and I’m a slow reader. Follow the directions and it will be OK. Make sure you a have wire strippers, crimpers and the kit to install this. You will not be disappointed and you will enjoy camping anywhere now, not just where there is power.

- clarnp49, United States on May 19, 2020

It works.

It’s amazing. Now I can use only one of my Honda generators. I can also use my standard 15 amp house outlet to power my trailer. My trailer sits about 60 feet from my house outlet so using a heavy gage power cord is essential. Even with the heavy cord the breaker would pop. Turn on current measures almost 28 amps. Way over breaker limit With the softstartRV installed current was reduced dramatically. See attached pictures taken before and after with a fluke meter with attached current clamp 1mv =1amp on the meter. Now I use my trailer at home without a special Electrical outlet being installed. Saves me a bill from an electrician upgrading my house
Awesome product!

- Amazon Customer, United States on July 12, 2020

Just buy one! It does exactly what it says it’s going to do!

My review is overwhelmingly positive, this device does exactly what it says it will do, it is as easy to install as they say it is, my thirty-year-old air conditioner was not in their database I sent them a message through their online ticketing system within 30 minutes I had a telephone call and email and exactly what to do in point I cannot review this product High Enough! My air conditioner Now does not overtaxed my generator at all the way it did prior to installing this wonderful device.

- Kirk, United States on August 11, 2020

Great product!

This Softstart is Great. Easy install and super performance!

- Jason Blakeman, United States on July 21, 2020

Very impressed – great product!

Thanks for helping me stay cool.

I purchased 2 SoftStartRVs, one for myself and one for a friend. DIY installation was easy. The compressor start-up is very quiet now, no more ‘THUMP’. My wife and kids don’t wake up in the middle of the night.
Before installing the SoftStartRV on my friend’s trailer, we tried starting his 13,500 BTU A/C using his single Honda EU2000i generator. With the Honda in ECO mode, the A/C fan running on low, we tried to start the compressor. The Honda went into overload and then disconnected from the load. After installing the SoftStartRV, we performed the same test. The A/C started fine and the overload light on the Honda didn’t even flicker.

The SoftStartRV should be standard equipment on all RV air conditioners.
Thanks again for an amazing product.

- Allison Van Buren, United States on March 7, 2020

Works like a champ!

I am converting a cargo van to a campervan. My intention is to be all electric. My goal was to be able to run an A/C while off-grid. I probably won’t actually do that very often, but if I can do that, then I shouldn’t have any issues with my electrical system’s capacity. Trying to start my A/C on anything other than shore power wasn’t doable. The generator would stall and/or trip the breaker. Same for my inverter — it would trip the output breaker immediately at startup. I had to read the instructions a couple of times — I was being extra careful since I didn’t want to damage this unit or my A/C — but once installed I could start my A/C no sweat with the generator OR the inverter. Looking forward to some cool(er) times ahead even when off-grid!
