1. Control function
The basic function of the solar street light controller is of course to have a control function. When the solar panel is irradiated with solar energy, the solar panel will charge the battery. At this time, the controller will automatically detect the charging voltage and output voltage to the solar lamp. Only then will the solar street light shine.
2. Stabilizing effect
When solar energy shines on the solar panel, the solar panel will charge the battery. At this time, its voltage is very unstable. If it is directly charged, it may reduce the service life of the battery, and may even cause damage to the battery.
The controller has a voltage stabilization function in it, and can perform constant voltage current limiting on the voltage of the input battery. When the battery is fully charged, it can charge a small part of the current or not.
3. Boosting effect
The controller of the solar street light also has a boost function, that is, when the controller cannot detect the voltage output, the solar street light controller controls the output voltage from the output terminal. If the voltage of the battery is 24V, it needs 36V to reach the normal lighting. Then the controller will increase the voltage to make the battery reach a level that can light up. This function is to be able to realize the lighting of LED lights only through the solar street light controller.
