Starting A 15,000 BTU A/C On A 2000-Watt Inverter.

In this video, Mike demonstrates using a 2000 watt inverter, the Jackery Explorer 2000, with a SoftStartUp™ to successfully start and run a Truma Aventa 15,000 BTU air conditioner.

He explains that the SoftStartUp™ eliminates the need for rooftop installation, and can be plugged into various power sources, including 15, 30, or 50 amp power sources.

Mike also shows that the inrush current needed to start the A/C is reduced to 26.6 amps, about 50% down from the typical 50-60 amps needed to get the A/C going. He highlights the effectiveness of the SoftStartUp™ and notes how innovative the product is.

Starting 1 A/C On A 2200-Watt Generator.

In this video, Mike tests the SoftStartUp™ with a Honda 2200 inverter generator and a Truma 15,000 BTU Aventa air conditioner.
He shows the real-time current draw, voltage, and inrush current, highlighting how the SoftStartUp™ significantly reduces inrush current, helping the generator avoid tripping.
The SoftStartUp™ works quickly and effectively. Overall, the device proves to be a great solution for managing the power supply of RV air conditioners and other appliances.

Starting 2 A/Cs On A 3000-Watt Generator.

In this video, Mike demonstrates the new SoftStartUp™ unit helping two 15k BTU air conditioners to be powered by a 3000 watt generator.
This eliminates the need to install a single soft start device in each RV rooftop A/C unit.
He measures the starting amps, running amps and voltage of the 2 air conditioners, and demonstrates how the units work when a SoftStartUp™ is in the mix.
Mike speaks to the all new SoftStartUp™ exceeding expectations and it’s solid performance.

Starting 2 A/Cs On A 30-Amp Power Pedestal.

In this video, Mike from RVElectricity.com demonstrates the use of a SoftStartUp™ device that allows for the efficient operation of multiple air conditioners in an RV.

He demonstrates that the SoftStartUp™ can be connected to the shore power, a generator or other power sources, and doesn’t require installation directly into the air conditioner unit.

Mike shows the testing process, recording voltage and current data, and highlights the ability of the SoftStartUp™ to power two 15K air conditioners simultaneously. He also mentions the versatility of the device, which can be used not only for RVs but also for powering houses in emergency situations.

Plug & Play For Easy Operation

The LEDs on the front of the SoftStartUp module indicate the power status on each leg of the input.

  • Plug SoftStartUp into power supply.
  • Allow diagnostic function to check power source.
  • LED will flash to indicate that the voltage input is satisfactory.
  • If either LED flashes rapidly, undervoltage has been detected on that leg of the circuit.
  • It will continue flashing until normal voltage is restored.
    After normal power has been established, plug RV power cord into SoftStartUp receptacle.
  • If the RV requires 30-amp connection, use the 30-amp adapter that is included with the SoftStartUp unit.

It definitely does the job

"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" Jim

Designed and assembled in the United States

"They are such wonderful, kind and thoughtful people, and the SoftStartUp is designed and assembled in the United States and they talked about how much they value that and place priority on that, and that is a company we want to get behind. Anything assembled, made, designed in the United States, very, very important for our country." - Laurie

This is an even more superior product.

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.
Wes Koshoffer, Full Time RVer
Loved it
Read More
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.
Chris Hinton, Hinton The Trail
They have given us the ability to RV in ways that we could not before
Read More
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.
Thomas and Melissa Baity, Home on Hitch
Flawless

"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." -Thomas Baity

This makes things so much easier!
Read More
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. - Matt
Chris Hinton, Hinton The Trail
It ran Perfectly!
Read More
We set up the SoftStartUp on the generator and we started on the first air conditioner, it worked. Added the second [air conditioner]. And then we went to the refrigerator. And then the water heater. And we were still able to run it. And then we switched over to propane…It still ran perfectly.
Wes Koshoffer, Full Time RVer
I couldn't be more pleased

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.
Mike, Living Free
It's going to change things

"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." - Mike

Working remotely from an RV with SoftStartUp
Read More
"One way the SoftStartUp has reduced stress for me personally is I'm working remotely from the RV right now, and when we lose power, that means I lose internet. And when I lose internet, that impacts my production. And the job that I'm doing right now remotely is production based. So it's very, very important for me to stay connected ...When I had the video call... I was sitting there drenched in sweat because I was too afraid to turn our AC on and risk losing our internet connection. So the [SoftStartUp] was going to save me from the situation I was in." - Laurie
Christ Hinton, Hinton The Trail
And we really believe that they can change it for you as well.

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.
