Chris at Hinton The Trail

“ I really like that the SoftStartRV™ stops the loud thumping noise, and allows me to run my air conditioner, even on low power. Before I had it, I worried that the summer heat would ruin our trip, because the A/C uses too much energy and trips the breaker. The team at SoftStartUSA even helped me install it over the phone, which made everything very easy for me. Now I don't have to stress about staying cool, and I know we can travel anywhere comfortably in the future. . ”

FAQ/Q&A

+

1. Q. What A/C problems does a SoftstartRV solve for a camper?

A. The main issue most every RVer faces is reducing or overcoming the initial spike to start the RV A/C. If you’ve got a motor coach, 5th wheel, big travel trailer, toy hauler that has 2 A/Cs and you’re at most campgrounds with 30-amp connection, you can only start 1 A/C because of the initial power spike to get the second A/C started. That’s a sweaty problem no one wants with only part of their vehicle cool. Or if you’re adventuring in truck campers, vans and tiny trailers, did you ever try starting your A/C with a small generator and maybe it blew a fuse or tripped a circuit breaker? Or did your small generator just stop under the heavy A/C starting spike? One RVer, was so overcome with frustration, he leaned against the closed door of his camper and silently screamed in the dark, with no power. Once is enough, right. We all learn. We go without A/C and spend another sweaty sleepless night, get a large generator, or get lucky and find one of the few 50amp campsites.

There’s never been any smart, effective lightweight and low- cost solutions to all these camping problems…Until now.

Now you can gently start your A/C with no power spike. You can eliminate all these power spike problems with a SoftStartRV. You can get SoftStartRV and experience freedom! Freedom to adventure into national parks and remote campgrounds knowing you, your family and friends can stay cool. Freedom to run two ACs on a 30-amp connection. Never worry about a start-up spike preventing you from using the AC while you’re boondocking in your towable. Worry-Free camping at last! Until now, your only options were to find a rare campsite that offered 50-amp or to buy a back-breaking, heavier costly generator, or a more expensive inverter. Everyone knows these cost more money, often over $2000. New generators and inverters prices are increasing, and the cost problem for rewiring an older 30-amp system is not cheap either. It’s specially designed, engineered and tested for as all RVs: motor homes, 5th wheel campers, travel trailers, toy haulers, truck campers, vans, and tiny trailers.

The SoftStartRV reduces startup power demand by an amazing 70%. Now there is an easier/cheaper/better/ way to solve the RV A/C start problem. RVers can start their RV A/C without investing $2000 or more. The SoftStartRV™ is an innovative device that gently smooths-out startup power demand of the RV air conditioner’s compressor. You can use a small lightweight generator, like a Honda EU2200i.

The SoftStartRV reduces compressor startup power demand by up to 70%. The SoftStartRV unit controls the inrush of current by starting the compressor motor slowly. It controls the start-up voltage of the motor /compressor smartly to effectively reduce the inrush and outpouring current while starting-up. It consumes much less power from campground networks or a generator system but still delivers full startup torque for motors and compressors. This small, inexpensive, reliable device leads to happy RV campers enjoying their family holiday. There are over 355,000 motor coaches, travel trailers, toy haulers, fifth wheels, truck campers and folding camping trailers being sold each year. RV Industry Association research reports over 9 million RVs are journeying in North America, and there is a clear opportunity to meaningfully help a huge number of people.

2. Q. Why do I need a SoftStartRV™?

A. For RVers, travel trailers or truck campers who need to start their A/C using a small Honda 2200i generator, it’s an endless problem to get the A/C to start because the A/C starting surge spikes beyond the generator capacity. Every day, campers flip the A/C switch in order to chill off and it fails to start.

 
The main issue you face is reducing or overcoming the initial spike to start the RV A/C which leads to no A/C cooling, hot, muggy, and sticky camping, and sweaty sleepless nights. Until now, your only option was to buy a back-breaking, heavier costly generator, or more expensive inverter. Everyone knows these cost more money, often over $2000.
New generators and inverters prices are increasing, and the cost problem is not going away. Now there is an easier/cheaper/better/ way to solve the RV A/C start problem. RVers can start their RV A/C without investing $2000 or more. The SoftStartRV™ is an innovative device that smooths-out startup power demands of the RV air conditioner’s compressor. You can use a small lightweight generator, like a Honda EU2200i. The SoftStartRV reduces compressor startup power demand by up to 70%. The unit controls the inrush of current by starting the compressor motor more slowly. This small, inexpensive, reliable SoftStartRV™ unit leads to happy RV campers enjoying their time in the great outdoors.

3. Q. What does SoftStartRV™ do, and how does it work?

A. Compressor motors are connected in a way that lets them draw as much power as required to get up to speed quickly. Because of this design, compressor motors require a massive current surge when they start. On each motor identification plate, there is a notice called LRA. This is an abbreviation for Locked Rotor Amps and is the maximum current the motor can draw – according to the manufacturer.
During a typical start, you can expect your compressor to draw this current from the supply. RV rooftop 16000 BTU compressors are rated around 50 to 60 amps LRA. A standard 2000 watt inverter generator is appraised at 2000 watts peak which is about 16.7 amps at 120 volts AC. The generator will not start a load that draws four to five times its peak rating! The solution is to reduce the peak LRA so we created SoftStartRV™.


It is designed to connect directly to the compressor motor and reduce the power surge that occurs on startup. It achieves this by supervising the power provided to the windings of the motor on each AC cycle. SoftStartRV™ gradually increases this power (in less than one second) until the compressor is running. This increases the time it takes the motor to get up to speed and creates a very smooth start that reduces the peak current by 50 to 70% or more. An RV rooftop 16000 BTU, 120-volt compressor can now start with under 20 amps of current.

SoftStartRV™ (Install and Testing) and Summertime RV Preparation Tips!

Chad and Tara at Changing Lanes

I really liked how easy it was to install the SoftStartRV™ because it only took a few simple steps and made my air conditioner start up much quieter,. It solved a big problem for us by lowering the huge spike of power that happens when the AC turns on, which prevents our generator or inverter from getting overloaded,. In the future, this will make our RV trips better because we won't have to worry about our power shutting off when we are boondocking and trying to stay cool. I think this device from SoftStartUSA is great because it does exactly what it promises to do.

Chris at Hinton The Trail

I really like that the new SoftStartRV™ is way smaller than the old version and uses a "no cut, no splice" installation that is super easy to do. This device from SoftStartUSA solves big problems for us, like loud thumping noises and tripping breakers, so now we can run our air conditioner on a generator or just 30 amps. It changes our future RV trips because we can now plan to camp in hot places like the Florida Keys and still stay cool comfortably.

Dennis' SoftStartRV™ Story

Dennis

I really struggled to run my air conditioner with a generator in Florida because it would just stop working, leaving me sweating in the heat. The SoftStartRV™ from SoftStartUSA was so easy to put in, taking only about 45 minutes, and it works like a champ. Now I can camp far away from everyone and still keep my trailer cool and comfortable.

Will It Work With….?

Will the SoftStartRV™ allow me to run my RV A/C on a single Honda EU2200i?

A. Yes. Using our own Honda EU2200i at SoftStartRV, and we were able to successfully start and run the largest 115V RV and Marine A/Cs on the market, even from ECO mode, using SoftStartRV.

Will SoftStartRV™ allow me to run two A/C units on a single 30-amp utility hookup connection?

Yes, with a SoftStartRV connected to each A/C unit you can then run both on a 30-amp hookup

 Will SoftStartRV work on a household refrigerator?

No.

If I have a big generator or parallel two generators, will I need SoftStartRV™?

A. Yes, you probably need a SoftStartRV™. Power management is key and how large a generator and what appliances you operate at the same time. Without SoftStartRV™ the start surge is massive. Generators react to load by slowing down and decreasing the voltage to the air conditioner. If the decreased voltage slows down the generator, they overload and then the air conditioner can’t start. High outdoor temperatures increase the refrigerant pressures triggering a greater current draw. Customers with Honda EU3000iS generators and SoftStartRVs said when temperatures are high their generator won’t start the A/C consistently. Many 4KW generators do start a rooftop A/C consistently but they are much larger and heavier.
