HotSpot DC481VRF air conditioner / heat pump is designed from the ground up to operate on DC power. There is no AC power used inside or needed externally to operate the unit. DC power is connected to the outdoor unit. The indoor unit receives DC power from the outdoor unit. An all-DC system means you get the advantage of extreme high efficiency without the need for inverters.

The DC4812VRF is a variable capacity, variable speed, variable refrigerant flow unit. Variable refrigerant flow & capacity means that the air conditioner is always the right size for the conditions and is never wasting power.

This unit uses SeaSpray anti-corrosion technology including hermetically sealed compressor, sealed circuit boards, and silica-nanotech condenser and evaporator protection.

Using technology similar to SEER 27 air conditioners, the DC2418VRF compressor runs on DC power at various frequencies and refrigerant flow depending on cooling load. The all-DC solar air conditioner uses DC power directly without needing an inverter or other AC power source. Due to solar voltage fluctuations the unit cannot connect directly to solar panels and must have a stable source of power such as batteries.

Depending on conditions, the entry-level setup can operate up to 10 hours per day using 4 x 250W panels. A configuration of 6 panels can provide up to 15 hours of daily operation, with 8 panels yielding up to 20 hours. A 10 panel configuration can handle up to 24 hours per day operation. Batteries and charge controller must be sized appropriately.
