How Do Solar Street Lights Turn On At Night


The daily lighting and extinguishing of solar street lights are operated by its internal controller. In the daytime, the power generation voltage of the battery panel is high voltage 2v (the rated working voltage is
17.4v). At night, because there is no light, the voltage generated by the solar panel will slowly approach 0;

Under normal circumstances, when the sky will be dark, the generating voltage of the battery panel is
2v, this is the controller determines whether the light should turn on by judging the voltage of the solar panel.

Explanation of working principle of all in one solar street light:

During the day, solar street lights are under the control of the intelligent controller. The solar panels absorb solar light and convert them into electrical energy after being irradiated by the sun. Features.

The DC controller can ensure that the battery pack is not damaged due to overcharging or overdischarging. It also has functions such as light control, time control, temperature compensation, lightning protection, and reverse polarity protection.
