Q&A

+

General Performance and Benefits

Q: How do I know if my SoftStartUp is working?

A: Look at the LED indicators. Two green lights indicate a 50-amp service, and one green light means a 30-amp connection. You should also notice smoother appliance startups with no tripped breakers or flickering lights.

Q: Will SoftStartUp reduce my RV’s power consumption?

A: It does not lower the normal running power of appliances. Instead, it manages the inrush current at startup to prevent power spikes and interruptions.

Compatibility and Usage

Q: Can I use SoftStartUp with a 30-amp power source?

A: Yes, by using the provided 30-to-50-amp adapter, you can safely connect to a 30-amp supply.

Q: Will it work with my generator in ECO mode?

A: No. ECO mode does not provide sufficient startup power for high-demand appliances like air conditioners.

Installation and Setup

Q: Do I need special tools to install SoftStartUp?

A: No tools are required. It is a plug-and-play device that connects directly between the power source and your RV.

Q: Can I use SoftStartUp in combination with a surge protector and voltage booster?

A: Yes. Plug the surge protector into the power pedestal first, followed by the voltage booster, then connect the SoftStartUp, and finally plug in your RV.

Environmental and Maintenance Considerations

Q: Can SoftStartUp be used in extreme weather conditions?

A: Yes, but avoid direct sunlight in high heat and protect it from freezing water in cold conditions.

Q: Does SoftStartUp require maintenance?

A: It is maintenance-free but should be periodically checked for secure connections and cleaned of dust or debris.

Customer Support and Warranty

Q: What should I do if my SoftStartUp is not performing as expected?

A: Check connections, verify power sources, and consult the troubleshooting guide. If issues persist, contact customer support.

Q: What is the warranty policy for SoftStartUp?

A: The device comes with a 90-day satisfaction guarantee and a 1-year limited warranty. Contact support for claims or technical assistance.

Mike was great!

Lia Eyre, Llama Llama Adventures

"Mike was great! He even sent us photos of him getting selfies with Llamas and he and Trevor had a great talk about music. We love when we can connect with the brands we are working with and the people behind the emails and phone calls. I just wanted to share how fantastic that feels." - Lia Eyre, Llama Llama Adventures.

Power Everything

Thomas & Victoria

“This is good news because we’ve restarted this thing about five or six times since we’ve been camping out here and we’ve been able to power everything we needed without overloading the generator,” said Thomas.

Image banner

Flawless

Thomas and Melissa Baity, Home on Hitch

We were able to start our two air conditioners off of our 3000 Watt champion inverter generator and it worked flawless. So it's a good option if you're looking into soft starts, you want to put 'em on your rv, but you don't want to have to climb up there and do the install or pay somebody to do it for you, then this is a great option.

Image banner

They have given us the ability to RV in ways that we could not before

Chris Hinton, Hinton The Trail

We have used the SoftStartRV for a year and a half. And now the SoftStartUp for the last four plus months. And they just work. They have given us the ability to RV in ways that we could not before, whether that's in low power conditions or just getting to use it with a generator….These are all things that we couldn't even think of when we first started RVing and SoftStartRV, and now the SoftStartUp, have changed all of that for us.

Image banner

Loved it

Wes Koshoffer, Full Time RVer

One of the other things that I really found great about this [SoftStartUp] unit was the ease of use, and when the air conditioners were kicking on and off as the compressors cycled, it was noticeably quieter and you could tell that the power draw was just an awful lot less, which is better in general for the electrical circuitry and for the rig.

Image banner

I couldn't be more pleased

Wes Koshoffer, Full Time RVer

I couldn't be more pleased with the idea that I can run dual air conditioning units and miscellaneous loads on 30 amp service in this RV.

Image banner

And we really believe that they can change it for you as well.

Christ Hinton, Hinton The Trail

We actually went RVing for three plus straight months and with one hundred degree temps. We also Boondocked for four straight weeks in Key West and 80 degree temps running our air conditioner with our generator. We've mooched docked at friends' houses using the 15-amp power plug and have been able to run our air conditioners. These are all things that we couldn't even think of when we first started RVing and SoftStartRV, and now the SoftStartUp, have changed all of that for us. And we really believe that they can change it for you as well.

This makes things so much easier!

Matt and Laurie, Why Not Wander

We started using the SoftStartUp, which we love because it's plug and play. We don't have to, or I didn't have to, get up on the roof and install soft starts on the A/C units. You literally just plug this in and it's allowed us to run our A/C, and the water distiller, our coffee pot, and we're not constantly tripping the breaker... I was totally willing to get on the roof and install on the acs, but now that we have this and this product is out there, this makes things so much easier.

Image banner

It’s Pretty Stout

Shawn

We’re running a lot of stuff off this already. We’ve got two acs running, we’ve got a residential fridge running a dehumidifier, three fans, and we actually ran the microwave for a little bit and we haven’t had a hiccup yet. So first impressions are, it’s pretty stout.

Image banner

I am most excited about

Adrian

What I'm excited about and I think most people will be able to use the most is running one AC on a 20-amp house circuit.

Image banner

Learning a new Trick

Larry Grimm

Here’s the trick, how we’re able to use either one of our ACS on a 2200 watt generator, and that’s using the soft start up right there.

Image banner

Whole new idea

David Tigner

It's a whole new idea and I think just simplifying it down where it just plugs in and unplugs and you just take it with you the whole time. No extra work involved makes it a simple thing. So anyway, that's pretty cool. I really like the product and it's pretty cool and it's a good company to work with.

Image banner

It's going to change things

Mike, Living Free

Since using this, I haven't had one single breaker pop at all, not even close... Your AC unit...compressor's going to last a lot longer using the SoftStartUp.

Image banner

Definitely a win-win

David Tigner

So that is definitely a win-win. So it’s nice to be able to have something like this available to us as RVers. And so I really applaud this company. Doug was saying they’re continually working to make it better and come up with better ideas on this and everything. So I think that’s got to be something said for the company.

Image banner

It definitely does the job

Rhonda and Jim Hill, R&J RV Adventures

Now with the softstartup, we had that plugged in on eco mode and all the systems worked fine, the air conditioner didn't have the surge of electricity that knocked out our wifi or TV, So that tells me it definietly does the job

Image banner

This is an even more superior product.

Suzannah Hinton, Hinton The Trail

We were already impressed with the original soft start [SoftStartRV], because we have it on both of our air conditioners and it really makes a difference with the noise and how it starts up…Normally when the bedroom air conditioning comes on, it’s really loud. [With the SoftStartUp] I didn’t even hear it. This is an even more superior product.

Image banner

No climbing on the roof

Adrian

No climbing on the roof, no messing with wires, none of that. Just use this, plug it in, and you’ll have AC.

Image banner

Glad it Worked

Larry and Alice

Crank [the A/C] down… It came on! I’m glad it worked.

Frequently Asked Questions

Got questions? We’ve got answers! Click to see all FAQs

What is the SoftStartUp™ soft starter and how does it work?

The SoftStartUp is an electrical soft start device that helps to reduce the amount of power your appliances need when they start up. It’s especially good for things like air conditioners, refrigerators and microwaves that use a lot of power at startup.

How do I know if I need a SoftStartUp for my RV?

If you’ve had issues with your A/C starting up, or other appliances shutting off when the A/C kicks in, then a SoftStartUp could be a big help. It smooths out the power demand so everything runs better together.

How quickly will I notice the benefits of installing a SoftStartUp?

You should notice the benefits immediately after installation. When you start an appliance, there should be no more dimming lights or tripped breakers, showing that the SoftStartUp is doing its job right from the get-go.

How do I know if the SoftStartUp is working correctly?

Look at the LED indicators on your SoftStartUp unit after installation. Two steady green lights indicate a 50-amp service is being used, and a single green light indicates that a 30-amp source is being used. Also, you should notice a smoother start when turning on high-demand appliances, with no flickering lights or tripped breakers, indicating that the inrush current has been effectively managed.

What should I do if my SoftStartUp is not showing any LED indicators after installation?

If the LEDs are not lighting up, first check all connections to make sure they’re secure and correct. Also, verify that the campground power supply is functioning properly. If everything seems in order but the unit still isn’t working, contact our customer service for further assistance.

Will the SoftStartUp reduce the power consumption of my RV appliances?

The SoftStartUp does not decrease the power used by your appliances during normal operation, which is actually beneficial. Each appliance has a specific running current necessary for proper function. The SoftStartUp specifically addresses the surge of power needed at startup, reducing its impact to ensure seamless operation of your devices on the same electrical circuit.

What air conditioning start-up issues does a SoftStartUp™ RV soft starter solve for RV enthusiasts?

SoftStartUp effectively smooths-out power fluctuations, ensuring your RV’s air conditioner starts seamlessly without overloading your generator or campground power source and causing it to shut off.
