Don't get caught in the heat. The SoftStartRV kit is the perfect tool to quietly fire up your AC with ease and run it more efficiently on those hot and humid days. Designed, engineered, and tested for all RVs, this small, lightweight soft starter reduces your AC's start-up power demand by 70%, allowing you to start up and run your AC while also running your electric water heater, coffee maker, and other appliances without the fear of tripping a circuit breaker or overloading your generator. Best of all, the SoftStartRV eliminates trailer shaking and that loud thumping and clunking in the middle of the night from your AC's compressor, giving you a smooth operation along with a cool, quiet night's sleep.


The SoftStartRV works great for a variety of setups. Use it to start up and run your 15,000 Btu AC on a 20-amp household hookup, small portable generator, or when moochdocking (RV camping on a friend or family's property for free). You can also run two 15,000 Btu ACs on a 30-amp hookup with no problem (additional soft starter required for each AC unit). This handy device lets you ditch that large or 2nd generator, used to help power your AC in high altitudes, for a single 2200-watt inverter generator that will start your AC right up to keep you cool while boondocking at 6,000 to 8,000ft above sea level. 1 SoftStartRV kit is required for each AC unit.

SoftStartRV Soft Start for Single Zone Air Conditioner Setup - Qty 1 - SSR54FR

Average Customer Rating:  4.7 out of 5 stars   (47 Customer Reviews)

Reduce your RV air conditioner startup power demand by up to 70 percent and eliminate that loud, clunking compressor noise. Start and run your AC and other appliances without the fear of tripping a breaker or overloading your generator.

by:

The installation was straight forward, good instructions from the manufacturer. Installed on a Dometic Brisk III 13500 btu AC. Couldn't measure start up amperage before, peak too quick for my meter (50+ amp peak I assume) after installing it, measured 29amp peak start up.(happens under 1s) My 2200w Generac generator runs the AC now. Don't hear the compressor kick on, so the AC is quieter.

Q

6/21/2023

This product is working great, quieter AC function lower starting amperage.



by:

Performs as advertised! Start up is much quieter and amp load is significantly less. Easy to install and technical support from actual designer was spot-on.



by:

An accessory you should not do without. Allows me to run the Dometic AC unit on a 2500W propane fuel generator with no problem! Install was pretty straightforward, but access to the roof of the RV is always a bit of a pain.



by:

Does what it's supposed to do - made my little genset capable of now running my A/C. Install was a bit complex, but your tech support was WAY HELPFUL during the install.
In a word -thanks!

Jim

Great! The original review is still accurate



by:

This is great. It allows me to run one of my AC with my 2200 generator/inverter. This also allowed us to run both units on a 30amp service without issue last summer. Using small generator /inverter unit we will be able to camp comfortable overnight without paying for campsite when traveling. Cost now will be 1/2 gallon of gas for the 6 to 8 hours needed.



by:

I have made a couple orders now with e trailer great experiences. Friendly knowledgeable and patient. Awesome company and very fast delivery from order to in hand.



by:

Looks of good quality, haven't installed it yet due to weather conditions, instructions seem clear and precise



by:

The installation was fast and easy and the specific instructions for my unit were clear and easy to follow!



by:

works just like to other one I had years ago. But I sold that rv and so now I needed another one. They work just like the man said. A good buy, I will keep one on my rv all the time. Thanks Ben



by:

Fast shipping. We just had it installed a couple of days ago but so far so good. Thank you.



by:

Best upgrade I have made to my trailer. Can run the a/c on a 15 amp outlet or a 2200 watt generator



by:

I installed this device yesterday on my Dometic 13,500 BTU rooftop AC. I did download a wiring diagram from the Mfg's web site that matched my 2010 unit. All wire colors were correctly identified. One issue I had is that the connection on top of the Compressor requires a flag type disconnect instead of an inline disconnect. I had to order some flag connectors to do this. I tested it today on my Wen Generator 1900 running watts 2300 starting watts and it started and ran fine. Prior to this installation the AC would not start on generator, it pulled too many amps and shut down. I cannot say how much the new starting amps are as my power monitor is not communicating. But very happy with the results.



by:

Wanted to use my 2500w generator! Very skeptical if this was a viable solution. Product website has excellent install for my brand ac and looks to cover majority of ac systems out there. Direction are extremely simple. Took me a bit to figure out each step as they may of been to simple for each step? But after taking a minute to fully absorb the instruction it all went really easy. No cutting to OEM wires so easy to return to normal if needed. AC started like a champ. Even on shore power you can’t tell that the AC kicks in. Super cool. Not sure why this is not standard on RV’s. Is it cost ? Or will this damage the AC in the long run? We will see. But as for now it’s a hit! I never post feedback. But if you want to run your AC on a generator that can’t make it over the start up load this is the ticket! Love it.



by:

Worked as advertised, reduced compressor start up amp draw significantly. Hard to measure accurately but 12-14amps on my unit. No fear if unit comes on while coffee pot, lights and tv are on while running on a Predator 3500 by Harbor Freight.



by:

Received the item on sunday and installed tuesday afternoon, the acquit working during a hot spell and repair parts were not available. I installed the soft start and the ac unit started up and was much quieter when the compressor starts and runs. Don't have the ability to measure starting current but it seems to start the compressor much smoother.



by:

Allows newer AC unit to run on older ge nerator



by:

This product is a simple DIY project. I am amazed at the smooth transition on my
generator compared to it bogging down before.



by:

Received right on time and in great shape. Installed without any problems with the instructions and print out from Etrailer's web site. Will save alot of gas by not having to use both of the EU2200 Honda's that I have been using while dry camping. Happy customer!



by:

This is a must for those campgrounds with only 30 amp (or smaller) hook-ups. Haven't tried it yet with my small inverter generator but I feel confident that it will work just fine.



by:

The only complaint is you didn't ship the installation kit.
I called and you are shipping it to me.



by:

This Soft Start works great!!



by:

Great product, etrailer are great folks to work with



by:

Part works great which allows me to run my A/C on a 20 amp circuit!
:)



by:

Works great!

As always great service

  • Running Power To A Residential Refrigerator In An RV
    I have a solution for you. The minimum you are going to need is a Go Power Heavy-Duty Modified Sine Wave Inverter - 1,000 Watts - 12V # 34280176 paired with a SoftStartRV Soft Start for RV AC Units - Qty 1 # SSR54FR. This however is the lowest power level to use and it may still struggle. I recommend using the Go Power Industrial Pure Sine Wave Inverter with Transfer Switch - 1,500 Watt - 12V # 34279458. This will give you enough power to run the fridge. This exceeds the 1000w minimum...

  • Do You Recommend the SoftStartRV # SSR54FR for My Travel Trailer when Using Full Hookup?
    While it is definitely not required when you stop at full hookup sites, the SoftStartRV Soft Start for RV AC Units - Qty 1 # SSR54FR definitely helps by limiting the stress applied to your AC's motor, drive train, and compressor. This is impactful because this ultimately leads to the overall lifespan of the AC. Purchasing a new AC and the pain of installation is definitely something that no one wants to go through before it is absolutely necessary. However, the AC will still be fully operational...

  • Will A Soft Start Help To Run A Furrion 13.5K BTU AC Unit With A Honda 2200 Generator

  • Could 2,200 Watt Generator Power Advent Air AC Unit
    The Advent Air RV Air Conditioner with Ceiling Vent and Start Capacitor part # ADV94FR requires 3,000 watts for starting and 1,000 watts while running so to power it with a 2,200 watt generator you would also need the SoftStart # SSR54FR.

  • Comparing SoftStartRV Soft Start for RV AC Units # SSR54FR Vs Advent Start Capacitor # ACMSCKIT
    The SoftStartRV Soft Start for RV AC Units # SSR54FR is not just a larger capacitor like the Start Capacitor for Advent Air RV Air Conditioners # ACMSCKIT. The SoftStartRV kit ties into both the run and start capacitors to allow the A/C to start up and run your 15,000 Btu AC on a 20-amp household hookup. It has an integrated bypass connector that prevents the unit from overheating and reduces the risk of the capacitor exploding and risk of fire. It is also IP65-rated against dust and water...

  • Can the SoftStartRV Soft Start Be Used on a Furrion A/C
    The SoftStartRV Soft Start # SSR54FR was designed and tested for all RVs and motorhomes. So you are correct that it can be used for a Furrion A/C as long as it is a single zone A/C. Some of the Furrion models already have a start capacitor. If you are unsure of your Furrion, you can provide me with the model number of your A/C and I would be happy to look into it for you.

  • Replacement Start Capacitor for a Furrion Chill FACR14SA-BL Air Conditoner
    The Furrion Chill FACR14SA-BL does already come with a start capacitor built-in. So you would not want to add the SoftStartRV Soft Start for Single Zone Air Conditioner Setup # SSR54FR. If the start capacitor on your Furrion Chill FACR14SA-BL has gone bad, we do carry the replacement start capacitor. - Replacement Start Capacitor for Furrion 14,500 Btu RV Air Conditioners # FR45FR.

  • Does Furrion Chill RV Air Conditioner System Have a Soft Start Feature
    The Furrion Chill HE RV Air Conditioner System - Dual Zone - 15,000 Btu - LED - White # FR67FJ comes with 2 start capacitors, one for each AC unit, which is the Furrion version of the SoftStartRV Soft Start for RV AC Units # SSR54FR you're looking at. According to the specs there is a heat mode for the Chill system that will work when your furnace is enabled. From what I was reading it looks like it more or less just uses the fans in this situation to promote air flow - I don't believe...

  • Recommended Generator To Power Furrion RV Electric Fireplace, TV, And Lights
    The Furrion RV Electric Fireplace with Crystals - 30" Wide - Recessed Mount - Black, part # FF30SC15ABL, you have attached to your question needs 1,500 starting watts and 750 running watts. Your generator should have enough power to start your fireplace, tv, and lights in the future. I recommend the A-iPower 2,000-Watt Portable Inverter Generator - 1,600 Running Watts - Gas - Manual Start, part # 289-SUA2000i. It is rated for 120V. It provides 2,000 starting watts and 1,600 running watts....

  • Will The SoftStartRV Soft Start Fit Under Cover On Dometic Penguin II?
    Yes, there is enough room under the covers for your Dometic Penguin II AC's to install the pair of SoftStartRV Soft Starts # SSR44FR. The main unit comes with a good length of wiring so it does not have to mount where your current electrical components mount and can mount where there is more room.

  • SoftStartUp vs SoftStartRV Power and Operating Comparison
    Right, the SoftStartRV Soft Start # SSR54FR is a standalone unit you install inline with the AC unit while the SoftStartUp installs inline for the entire RV.

  • What Are The Main Differences Between The SoftStartRV & SoftStartUp?
    While we don't carry the SoftStartUp, we do have the similar SoftStartRV # SSR54FR.
