Solar Hybrid Air Conditioning: Run on AC, DC, or Both

Solar-powered air conditioning used to mean a pile of batteries and voltage controllers. Here's how Airspool's hybrid mini split runs on clip-on solar panels alone, or backs itself up with a regular wall outlet, whichever the sky gives you.

In this video

  • Old solar AC setups needed external voltage controllers and up to 16 batteries; Airspool skips all of that
  • Clip two to four solar panels directly onto the unit to run fully off-grid when it's sunny
  • Plug into any standard 120-volt outlet to get 22 SEER backup cooling on cloudy days or at night
  • Free iOS/Android app lets you schedule run times, change modes, and track solar savings remotely
  • Keeps running during grid outages, making it useful for garages, sheds, RVs, and emergency cooling

Questions this video answers

Can a mini split really run on solar panels without batteries?

Yes. Airspool's hybrid units use variable-speed DC compressors and fan motors, so you can clip two to four solar panels straight onto the unit and run it off-grid whenever the sun is out, with no batteries or external voltage controllers needed.

What happens when it's cloudy or nighttime and there's no sun for the solar panels?

You just plug the unit into any standard 120-volt wall outlet. It automatically supplements or replaces the solar power and still delivers super-efficient 22 SEER cooling.

Why couldn't older air conditioners run on solar power?

Traditional AC units only ran on alternating current, while solar panels produce direct current, so you needed extra panels and electrical conversion equipment just to make it work. Early DC solar units solved part of that but still required external voltage controllers and up to 16 heavy, expensive batteries.

Can I control the unit remotely or see how much I'm saving?

Yes, Airspool has a free iOS and Android app that lets you schedule on and off times, change temperature and modes, and track your solar savings from anywhere you have a connection.

Will a solar air conditioner still work if the power grid goes down?

Yes. Because the unit can run directly off clipped-on solar panels, it keeps cooling or heating even during a grid outage, which makes it useful for emergency air conditioning to keep your family safe.

Where can I use a solar hybrid air conditioner besides my house?

It works well in garages, sheds, attics, dog houses, trailers, and RVs, essentially anywhere you want free cooling or heating without running new electrical circuits.

You say, "Help! I need air conditioning, but I don't need sky-high electric bills." Lucky you! Finally, solar-powered air conditioning has arrived.

In the past, air conditioners weren't good candidates for solar because they weren't very efficient and only ran on alternating current, not the direct current that solar panels create. So extra solar panels and electrical conversion were required. Not good! Later this was sort of solved, but solar-powered DC units needed external voltage controllers, a slew of solar panels, and up to sixteen heavy and expensive batteries to keep running. Not much better.

Now, Airspool allows you to directly and effortlessly clip two to four solar panels onto your unit to run off-grid when it's sunny. Cloudy or nighttime? No problem. Plug an Airspool into any standard 120-volt outlet to supplement the solar and get super-efficient 22 SEER cooling.

This simplicity gets you both heat and cooling in some pretty untraditional places. And Airspool's free iOS or Android app allows you to schedule on-off times for your unit, change temperatures and modes, and see your savings with solar from anywhere you're connected.

Do some good while you're doing well. Save the environment and save money with Airspool.
