Simple, safe, and efficient. 

Reliable AC at night. Use for backup with a full battery on standby in case of an outage. For anyone who doesn't like bills - units pay for themselves in no time. Invest once, and let the sun do the work.

Heat and cool with pure DC power without inverters. Our Pure DC Heat Pumps are in stock and ship same day from our warehouse — delivery in 3-5 days nationwide. The price includes shipping and tax, there is no extra fee for delivery to you and no waiting. Declare your energy independence and use your own power to stay comfortable year-round with zero electric bills in perpetuity.

Any Power Source. Any Time.

A pure DC heat pump can be powered by mains power, solar, wind, generator, or any combination thereof — at the same time. Multiple units can be wired in parallel to the same source of low voltage power — which can be as simple as 2 car batteries. It powers down if the voltage gets low, and once the battery is sufficiently recharged, it can pick up right where it left off.

It’s the longest-running backup HVAC during outages. A power bill exorcist without the hassle of grid-tie solar issues. A commercial grade HVAC for places where no city power goes. For such problems, a pure DC heat pump is a reliable, high power, safe, low voltage platform that provides ultra-efficient HVAC day or night, summer and winter. Any source of electricity can be used to feed the system without current surges.

No inverter. 16+ BTU/h per Watt.

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.

The additional cost of a Pure DC air conditioner pays for itself in no time when you consider that you don't have to dedicate an inverter for their use, do not need to build out high voltage electric wiring, and need only half the solar power and battery storage to keep them running at night compared to regular HVAC units. 

Go Big: Grow to any Size.

Full Battery window units and mini splits can air condition a structure of any size. The modular nature of DC heat pumps allows simple scalability without expensive electric infrastructure. Centralized wiring is no longer required.
