With the development of technology, the current street lights are mostly converted by solar electricity, so that energy saving, safety and convenience can be achieved. And it is equipped with a solar street lamp controller, which can be controlled and displayed by a microprocessor intelligent charge and discharge controller, using high-quality, low loss and long life components to ensure reliable performance, so that the solar street lamp system can work normally for a long time and reduce the maintenance cost of the system.
So what is the role of the solar street light controller?
1.Control function
The basic role of the solar street light controller is, of course, to control. When the solar panel is exposed to the solar energy, the solar panel will charge the battery, and the controller will automatically detect the charging voltage, thus giving the solar lamp output voltage, so that the solar street lamp will shine.
2.Pressure stabilizing action
When the solar energy shines on the solar panel, the solar panel will charge the battery, and its voltage is very unstable. If it is charged directly, it is possible to reduce the service life of the battery, and may even cause damage to the battery.
The controller has a voltage regulator function in which it can carry out constant voltage current limiting on the voltage of the input battery.When the battery is fully charged, a small part of the current can be charged, or no charge.
3.Boost pressure action
The controller of the solar street lamp also has a voltage boost effect, that is, when the controller cannot detect the voltage output, the solar street lamp controller controls the output voltage from the output end. If the voltage of the battery is 24V, but 36V is required to reach the normal light, the controller will increase the voltage, so that the battery can reach the level of light. This function must be through the solar street light controller to achieve the LED light.
