The core component of solar street light-controller
The core components of the solar street light must belong to the controller, and the controller determines the light time and light intensity of the solar street light; let’s take a look at the specific functions:
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 to provide the solar lamp. Output voltage, so that the solar street light will light up.
2. Voltage stabilization When solar energy irradiates 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 stabilizing effect 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. Boost functionThe 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, but it reaches normal 36V is required to turn on the light, and the controller will increase the voltage to make the battery reach the level that can turn on the light. This function is to be able to realize the lighting of the LED lights only through the solar street light controller.
