Product Description

3000w 48vdc 220vac 380vac Off Grid Solar System Whole Set Residential
Off grid solar systems are widely used in areas without electricity, power instability, islands, communication base stations and inconvenient wiring for street lights or monitoring systems. The photovoltaic array converts solar energy into electrical energy when there is light, and stores the electricity for the battery pack through the solar controller; when there is no light, the battery pack discharges through the solar controller to supply power to the DC load, and can also reverse the discharge into AC power through the inverter to supply power to the AC load.
