18KBTU DC Solar Aircon

The DC48V solar air conditioner is designed from the ground up to operate on DC power. There is no AC power used insided or needed externally to operate the unit. DC power is connected to the outdoor unit. The indoor unit received DC power from the outdoor unit.

If your power source is native 48VDC (or -48VDC) as part of a telecom or off-grid solar application, Our DC4812VRFS all-DC air conditioners are your most efficient cooling choice. DC48 air conditioners can substantially reduce power supply/generation costs and battery requirements. An all-DC system means you get the advantage of extreme high efficiency without the need for inverters.

Various Applications

The DC4812VRFS is a purpose-built DC powered air conditioner heat pump for native DC power. It's designed to conserve power, and operate reliably for many years without maintenance. Our Anti-Corrosion technology protects circuit boards, condenser, evaporator, compressor, and fan motors from salt air corrosion.

In an off-grid solar configuration where an AC-powered air conditioner is running from inverted solar power, the power is actually being converted twice. First, the native DC power from solar panels is inverted to AC by the inverter, and then the power is immediately converted back to DC after entering the air conditioner. Sound wasteful? It is, requiring more solar panels and more batteries as a result. A key difference with our system – the DC4812VRF unit skips all of these conversions and uses the DC power directly without conversion loss.

System Diagram

In addition to avoiding the cost and power loss of an inverter, our system is engineered from the ground up for use with solar. Special electronics anticipate and smoothly handle voltage fluctuations of up to 38% without affecting the operation. In addition to the compressor and control circuits, all other electrical components are DC powered including high efficiency DC fan motors, DC valves & solenoids, etc. There are no inverters used inside the system.
