The air conditioner is often the biggest load in your dwelling & draws the most power, all day long. Using a 24V or 48V Pure DC Air Conditioner solves several problems:

1. Give your inverter a break. Air conditioning draws a lot of power. You need a very powerful inverter to keep A/C running. Even if it handles the load, it will hum, buzz, fans full speed, and be extremely annoying. Pure DC air conditioners wire directly to your DC battery bank / charge controller and do not need an inverter.
2. Supreme efficiency - by combining the pure DC power that solar panels provide with pure DC motors, the real world efficiency improvement is often 200% over using a regular 110V or 220V AC air conditioner. When you have limited solar power, this means you can run real, powerful air conditioning with less power consumption than ever before. A 1 ton Pure DC air conditioner draws at most 750 watts and often in the 550 watt range. Just think about how little solar panels you need to make this happen.
   
3. Pure DC air conditioners are safer because they are low voltage, don't emit EMF, and can be easily hooked up for use in marine, RV, trailer, camper, tent, glamping, and other situations where a regular air conditioner is not feasible.

While our high quality pure DC air conditioners are a little more expensive than their AC counterparts, the extra cost pays for itself in no time when you consider that you don't have to dedicate an inverter for their use, and need only half the solar power and battery storage to keep them running at night compared to regular HVAC units.
