Solar lighting system for the DC-independent photovoltaic system. Solar modules convert solar energy into electricity, controlled and protected by a controller, and convert electricity to chemical energy for storage in batteries. When electricity is used, the battery then converts chemical energy into electrical energy for use by a DC load or inverter for an AC load. The device stops working only when there is no light for a long time causing the battery to run out of power.
Solar street light consists of the following components: solar panels, solar controllers, batteries, light sources, light poles and lamp shell, and some also configure the inverter.
