The sun to the surface of a cell, cell can convert solar energy to dc output. Electricity through a wire connection, to solar power controller, the controller to adjust energy battery, battery energy storage down. When electricity, battery storage of electrical energy delivered to the load by the controller, for the use of the load. To form a set of independent power supply system.

System is the core component in solar power controller, the controller mainly complete photovoltaic cells to load the battery charging control and battery discharge control. To protect the battery will not result in a charge and discharge.
