How do solar street light lithium battery work?

Any Battery.html target='_blank'>Solar system consists of four components: a Battery.html target='_blank'>Solar panel, a Battery.html target='_blank'>Lithium Battery (storage battery), a special Solar controller and a light fixture. During the day, solar panels absorb sunlight to generate electricity and use a solar controller to regulate the voltage and current to charge the battery, which then stores the energy. This happens from the time the sun starts to rise until the sun goes down (that is, during the day, when there is light, the panels generate electricity and the battery has power inside).

The special solar controller detects when it is dark by detecting a decrease in the voltage of the solar panel. If it is to judge that it is night, the program in the controller will close the charging line and open the line, and then the battery provides energy for the LED lamp, and the led light source opens. The controller has the function of light control and time control. When the led is off several hours after dark, the light will be turned off automatically. The cycle continues day after day.
