Like all DC-Inverter air conditioners, the ACDC12 compressor runs on DC power converted from AC power. But this special solar air conditioner can also accept DC power directly from solar panels, without needing an inverter, controller, or batteries or the grid. The solar DC power directly replaces an equivalent amount of AC power from the power company and can cut daytime energy costs for air conditioning or heating by up to 80-90%.

During the day, the ACDC12C can get most of its power from solar resulting in an efficiency above SEER 35 when using two >/= 250W solar panels. The unit can be connected with up to three 375W panels. The system is designed for hybrid operation with solar providing most of the energy needed during daylight hours. This air conditioner can be connected to a 220/240VAC power source for 24 hr operation.
