The role of solar street light controller

1. Control

The basic function of the solar street light controller is of course control. When the solar panel illuminates the solar energy, the solar panel will charge the battery. At this time, the controller will automatically detect the charging voltage and output the voltage to the solar lamp, so that It will make the solar street light bright.

What are the functions of solar street light controller?

2. Voltage stabilization

When the sun shines on the solar panel, the solar panel will charge the battery, and its voltage is very unstable at this time. 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 regulation function in it, which can limit the voltage of the input battery by constant voltage and current. When the battery is fully charged, it can charge a small part of the current, or not charge it.

3. Boosting effect

The controller of the solar street light also has a boosting 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 needs 36V to reach normal lighting, The controller will then boost the voltage to bring the battery to a level where it can light up. This function must be realized through the solar street light controller to realize the lighting of the LED light.
