NEW!  Model ACDC12C 100% Solar Air Conditioner
NO AC Power or Grid Connection Required

solar hybrid air conditioner ADC12b

This is the 3rd generation solar air conditioner we’ve all been waiting for – designed for low cost, easy installation and a fast payback. This unique solar air conditioning technology requires no batteries, no inverter, no controller – just plug in the solar panels and start saving up to more than 80% on daytime cooling or heating costs.

This is the 5th generation of our ACDC12x solar air conditioner series with a new key feature we’ve had so many requests for – our new “C” model ACDC12C solar air conditioning technology requires no grid connection. Like previous versions, it also needs no batteries, no inverter, no charge controller – just plug in the solar panels and start saving up to 100% on daytime cooling or heating costs. A grid connection can be added to automatically allow operation at night, as well as to provide higher daytime capacity & uninterrupted operation during cloudy or low sunlight conditions.
During the day the ACDC12C can run exclusively on solar power with no AC power or grid connection when solar is strong enough. The maximum speed/capacity will be based on the level of available solar power available. If also connected to AC power source, the unit can run at full speed whenever needed, and will add in just enough AC power, if/as needed, while still primarily using available solar DC power.

The HotSpot engineering team created the world’s first DC solar air conditioner in 2007 and has led the world in solar AC design and quality manufacturing for more than 10 years. We are pleased to offer our 5th generation solar AC, the model ACDC12C. Like our previous solar hybrid versions, the ACDC12, and ACDC12B, the ACDC12C blends solar DC power directly with AC power to deliver a seamless cooling or heating experience while making the best use of free DC solar power. But unlike previous versions, the ACDC12C does not require an AC backup connection to operate during good sunlight conditions. During the day it can operate on 100% solar power.

When connected to both solar and an optional AC power source, the ACDC12C only uses small amounts of power from the utility company, if and as needed. Hybrid operation eliminates the need for batteries and allows use of the system 24 hours per day. The system primarily uses solar power, and mixes it with normal AC power, if available, at times when solar availability is reduced due to clouds, overcast sky, or at night. If the sun conditions are poor and no AC connection is available, the ACDC12C calculates the amount of solar power available in real time and reduces its speed to match the available solar power. Of course, the unit will not run without an AC connection in very low sunlight conditions, or at night. The ACDC12C includes a digital power display so you can get an idea of how much AC and/or DC power is being used in the system.

For home or office use, this system can cool an area for free with up to 100% of the energy coming from sunlight. In addition to cooling, the ACDC12C solar heat pump will provide solar powered heating, operating all the way down to an outside ambient temperature of 5 F. No matter how far north or south you are, this is the right system for you. No net metering needed. Single indoor unit.

How It Works

ACDC12C solar air conditioners need no batteries, and uses three or more (up to six) solar PV panels to deliver a huge savings. During the day, when air conditioning is needed the most, you can operate this unit with very little or no draw on your utility meter. At night, you continue to save due to the official SEER 22 rating on this unit. This solar mini-split air conditioner design allows you to put solar cooling into the area where it’s needed the most and avoid the security issues of an unsightly and noisy window unit. If your location needs heat during the winter, take a full 1-ton of the daytime heating load off of your main heating system for free and get a head start on evening heating requirements.  Since it’s a ductless system, it allows 100% of your heating or cooling to be delivered to where it’s needed without the loss that occurs in a ducted system. Note – this is not an “off-grid battery powered” unit, although adding batteries is possible, it is not the recommended use.
