What Is Off-Grid Solar Air Conditioner： Off-Grid Solar Air Conditioner is engineered from the ground up for use with solar. All electrical components are DC powered including DC Compressor, high-efficiency DC Fan Motors, DC Valves & Solenoids, etc. Off-Grid Solar Air Conditioner uses Solar Direct Drive Technology(SDDA) and IPS Model, It combines the feature of ACDC Hybrid Solar Air Conditioner and adds the function of battery backup though the IPS Control Model. So the A/C Unit can use AC, DC, and Battery power according to the customer requirement and the energy situation. The whole system just contains an A/C Unit, an IPS Model, a few PV panels and batteries. Compare with the regular AC Unit + Off-Grid Solar System, the solar energy utilization rate will enhance 20%-40%. The A/C unit working time will enhance 30-50%, in the same quantity of the battery and solar panel.
