How We Run Our Air Conditioning off Battery Power

Because of this little device, our solar set up and our lithium batteries, we can run our Air Conditioner without having to run a generator or being plugged into shore power. It’s a beautiful thing!

We first learned about a soft start when we wanted to figure out how to run our Air Conditioner on our RV when wild camping. I contacted Micro-Air and asked them about their soft starters, and which one would work with our RV A/C units.  I was told: The EasyStart will provide a minimum of a 50% decrease in the Locked Rotor Amp (LRA), bringing the A/C amp spike to (or below) 31a. If we installed this product, it should allow us to run our A/C using the inverter without spiking past the inverter’s 40a max.  Here’s that video:

Fast forward a few years and now that we are living on a sailboat (and enduring steamy tropical temps) installing an easy start on our air conditioner was a big priority.  Not only for our personal comfort, but for dry air circulation in the boat (helps prevent mold) and the safety of our cats while out at anchor when we leave the boat.

  1. I’m an older sailor/cruise but curious about wind power…do you use it? Maybe compare amps generated per hour vs solar? I love your blog!

  2. Question for Mateo:
    My 1000/1500 W pure sine inverter will run my full size washer with no problems, but blows 100 amp fuses on my gas drier. Will Easy Start soften the startup spike on the drier motor enough to run it?

  3. Wow I love this idea but this is definitely something left to a professional. Glad to have all of this information available here. I had just been watching your videos on YouTube and now I am thoroughly enjoying everything on your website! Especially the quick links to Amazon! I’m afraid to see how much I’ve spent today lol. Sure hope you get the credit as it links directly to my app and I hit buy now!

  4. Have you guys figured out how long you can run your AC off the batteries before they go flat?

    • Well, that is a tricky question because it’s always going to vary depending on conditions. That said, I can say we don’t like to run it hard for more than a couple of hours because then we don’t have enough juice to do all the other things we need power for. We honestly don’t need it often but the biggest benefit is being able to set it to a higher temp (like 85) when we leave for the day and want to know the cats won’t burn up. It keeps the air moving and cycles on and off as needed to keep it reasonably comfortable but not drain the batteries.

  5. I was looking for the soft start and found this picture on the company’s website:

    they should use your picture in RV instead, dont you think 🙂
