Transferring solar energy into electric energy and storing it by utilizing solar cell, solar energy power supply can provide lighting for pastoral zones, borders and islands, DC power supply for base stations of mobile communication, microwave stations, etc. and AC power supply for stored-program control exchange in remote areas.
With microcomputer chips and contactless control technology, SD solar energy power supply controller possesses a variety of protection functions. After overcharge protection, the floating charging status of the storage battery is automatically entered.
