If your power source is native 48VDC (or -48VDC) as part of a telecom or off-grid solar application, SuperEn 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.
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
