This is the 3rd generation solar air conditioner / heat pump 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.

During the day it runs primarily on solar power and uses only small amounts of power from the utility company as needed. Hybrid operation eliminates the need for batteries and allows 24 hours per day use of the system. The system primarily uses solar power, and mixes it with normal AC power.

For home or office use, this system will cool an area for pennies with 80% or more of the energy coming from sunlight. In addition to cooling, the ACDC12b solar heat pump will provide solar powered heating, operating all the way down to an outside ambient temperature of -15ºC. No matter how far north or south you are, this is the right system for you.

ACDC12b solar air conditioners need no batteries, and only need two or three 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 draw on your utility meter. At night, you continue to save due to the SEER 21 rating on this unit. The 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 and get a head start on evening heating requirements. And because 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" unit, 220V utility power is required. If you have no AC power and need an off-grid solar, check the DC4812VRF model.

Solar air conditioning cooling and heating augmentation

Augmenting a space heating or cooling system with solar makes perfect sense. In addition to heating or cooling a small area, it allows you to add capacity to an existing system, or reduce the load on an existing system, either or both of which can save you money and add comfort. Solar augmentation also allows offsetting of higher daytime electricity rates and reduces the amount of early evening catch-up required by the normal system. The ACDC12b hybrid solar air conditioner allows you to add comfort without adding cost, and can sharply cut your daytime heating and cooling bills.


The ACDC12b installs just like a normal mini split air conditioner, then you connect the solar panels using industry-standard MC4 connectors. You can use 1, 2 or 3 normal solar panels (but not 12V "battery charger" panels) for a total of up to 900W. Note that the panels should be minimum 30V PV panels (30 to 39V), please review the specifications. The ACDC12b uses R410a, an ozone-friendly refrigerant, so it is legal for the customer to self-install however the hiring of a professional HVAC installer is recommended. If self-installing, you will need a vacuum pump to commission the unit.
