Reduce the startup amp draw of your RV A/C by over 70% with our partner SoftStart RV!

The hot season is here, and we have a solution to keep your RV’s power system cool as the temperatures climb!

Start Your Compressor Smoothly:

During initial startup, your RV roof air conditioner compressor can spike to over 52 amps which could overload a traditional 30-amp circuit and cause the breaker to trip.

With SoftStart RV technology you can reduce the initial amp draw by over 70% which means you can run two roof air conditioners on a 30-amp circuit or even one roof air on a residential 20-amp circuit.

    I have a Genesis Supreme 40CRXL with three A/C units. Will this device work for my toy hauler?

      Hello Michael,
      It will work on all AC units. The soft start replaces the start capacitor on the AC unit. When you operate an AC using a soft start, it slowly ramps the compressor instead of starting it hard and fast. By doing this is prevents an amperage spike. An air conditioner can get close to 20 amps normally at start and then run around 14 amps. Using a soft start, the amperage is always around 14 amps. It doesn’t bring down the running amps, just the starting amps. You could use it on all of you AC units. Since you have three units, 2 will be on one leg and then 1 on the other. Using soft starts means you will only spike to around 30 amps on a leg and 15 on the other when your camper has two hot legs rated for 50 amps each. It will allow you to use other components in the RV while using all 3 AC units at the same time. It just helps prevent tripping a breaker when the compressors turn on at the same time. It also helps the compressor last longer too. You just need to have one soft start per unit so you would need to replace all 3 to utilize this on all of the units.

    Will this work on my Rv?
    Is roof install the only option?
    Does this work with any type generator?
    What is the lowest watt generator it can be used with?
    Thank you

      Hello Teressa,
      The soft start replaces a start capacitor on the air conditioner itself. It makes it slowly crank up instead of an instant hard start. This prevents the amperage from spiking. These can only be installed directly onto the AC roof assembly by removing a capacitor and installing the soft start in its place. The generator you want to use depends on how many circuits you plan on operating. If you want to run an entire 30 amp camper, you would need a 4,000 watt generator. If you have a 50 amp camper, you would need at least a 5,500 watt minimum. If you have a 30 amp camper but only plan to run the generator and nothing else at the same time, you can use a 2,500 watt generator just fine. Air conditioners are on a 20 amp circuit and a 2,500 watt generator is equivalent to 20 amps so this is all you would be able to run on one. It is always best to get a generator sized to power your entire RV so you could use it the same as you would when plugged into shore power.

    I purchased two of these SoftStartRV units for my 2019 Jayco 27.5 HT and it’s the best thing I could have done right off the bat with in a few weeks of purchasing my rig and installing them, they were easy to install and worked like a charm start ups on 50 amps or 30 amps are so quiet and smooth the AC’s don’t wake me up in the middle of the night, and there is no power surge anymore best thing I did for my peace of mind get yours today you won’t regret it

    I have a Coleman Lite with 50 amp. You talk about savings on a 30 amp is there anything I could get to help save and cut cost on my 32 ft camper.

    2019 Wildwood X-lite BH263. Would the Softstart be beneficial to me?

      Hello Joe,

      The soft start is really only beneficial if you run off of a generator often or have issues tripping breakers when plugged into low amperage receptacles. A soft start just prevents the quick high amp draw from the compressor. It will draw high like normal, just not a huge spike. This is what causes breakers to trip and cords to heat up. If you never have this issue, then it really won’t help much. If you have two air conditioners and want to run them both at the same time when plugged into 30 amp, this would help. If you use a generator it can help you utilize other components while running the AC. It can also help if there is low voltage from an old outlet at a campground too. A lot of times you might have issues running the microwave and AC at the same time, this would help that. Soft starts do have their benefits but depending on how you use your camper, it could help a lot or just a little bit if any.

      Thanks!

      Hello Russell,

      Thank you for contacting us.

      Each AC unit requires its own SoftStart so if you only have one AC unit, you only need one SoftStart.

      If you have any other questions, please chat, email, or call Customer Service.

    This spring i installed one on each of my Coleman 15000 units and with that said i can run everything in my RV on a 30 amp circuit and never have an issue including the Microwave and running each unit together.
    I highly recommend installing them and with the help of the folks anyone can do it within 20 minutes.

      Hello Dale,

      Thank you for contacting us.

      Yes, you will need one for each AC unit. They take place of a capacitor so you will have to remove the shroud on top and open the access panel to the capacitors. You remove just one I believe and then mount the Softstart to the side of the housing. The mounting location is different for each AC model. It is fairly easy to install but each AC unit will need its own SoftStart installed. I will share the link to the installation manual that breaks down how to do it for each model.

            Hello Charles,

            Thank you for your patience. We have received the following response from our expert regarding your question:

            The outlet on your generator is rated for 20 amps. The AC in your camper is on a 20 amp circuit so technically you should be fine running the AC. The problem is with everything else in the camper. You will need to have everything else in the camper turned off for the generator to work properly and to prevent the breaker from tripping. If you aren’t running anything else, you should be fine. The soft start limits the peak amperage so it will be more around 14 amps when running. This does give you more room to use other things in the camper but you still have to be careful.

            Sincerely,
            Dan

    Getting the Startup plug and play adapter soon. Going to test and review soon. This seems like a game changer especially for anyone not confident or tech savvy.

      this is a capacitor that piggybacks onto your compressor start capacitor and increases voltage on start up thereby reducing amp draw…ohm’s law
