SOLAR OFF GRID AIR CONDITIONER
If your power source is native 48VDC as part of a telecom or off-grid solar application, Superen DC4812VRFS all-DC air conditioners are your most efficient cooling choice. DC48V 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. The 48V air conditioner is designed to conserve power, and operate reliably for many years without maintenance.

Complete System Diagram
Depending on conditions, the entry level set up can operate up to 10 hours per day using 4~6pcs 310w panels. A configuration of 6~8 pcs panels can provide up to 15 hours of daily operation, with 8~12 pcs panels yielding up to 20~24 hours. The batteries and charge controller must be sized appropriately.
IT WORKS DC Variable Frequency Technology
Air Conditioner Technology Background
It starts with the compressor which uses 95% of the power consumed by an air conditioner. In all ultra-high efficiency AC-powered mini-split units, household electricity enters the air conditioner and passes through a rectifier, a component that converts the incoming Alternating Current (AC) to Direct Current (DC). The DC current passes through a frequency driver which applies power to the motor. The frequency of the power determines the output of the motor, which can be digitally managed to precisely control the motors speed. Because DC power can be used more efficiently, all of the highest efficiency AC-powered heat pumps and air conditioners on the market use DC powered compressors.
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. Sounds wasteful? It is, requiring more solar panels and more batteries as a result.
