The Functions Of The PV Solar Power Lighting System Charge Controller
PV solar power charge controller is the core of the solar lighting system. More about the PV Solar Power Lighting System Charge Controller functions as below.
1. Control the solar panel to charge the storage battery;
The pv solar power lighting system charge controller can control the solar panel to charge the battery and reduce the high voltage solar cell to a suitable voltage for charging the battery. The pv solar power lighting system charge controller charges the battery by the three-stage charging method, namely, Constant-current charge, constant voltage charge, and trickle charge. In the constant-current charge stage, the battery is charged with the high current to charge the battery as soon as possible; When the battery voltage reaches the full voltage, constant voltage charging is used let the battery to saturated. Finally, it enters the floating charge, and the charging current slowly decreases to makes the battery fully charged. In summary, charging the battery through the controller can not only protect the battery, extend the battery life, but also charge the battery reasonably.
2. Control the battery to charge the LED light
The pv solar power lighting system charge controller can detect the battery voltage in real time. When the battery voltage is lower than its over-discharge voltage, the battery will be interrupted to charge the led lamp to avoid over-discharge, thus protecting the battery and prolonging its life.
3. Adjust the lighting power to change the brightness of the light;
The general LED light usually adopts a driving power supply to carry on the constant current of the LED, but this will cause power loss. It is more power-consuming to add an independent driving power supply to the street lamp system, so this method is not desirable. The pv solar power lighting system charge controller guarantees constant current output, which is determined by the characteristics of the LED light itself. solar power charge controller can also adjust the output current to change the lighting power, the power of the light determines the brightness of the LED lamp, which can be selected after using the controller.
4. Automatically turn on/off the LED light;
Solar cells also serve as a photosensitive component. The voltage of solar cells varies with the intensity of illumination. The pv solar power lighting system charge controller can detect the voltage of solar cells in real time, and determine whether to turn on/off the LED lamp. When the sky darkens, the light intensity becomes dim, the voltage of solar cells decreases, and then the pv solar power lighting system charge controller will turn on the LED light after detecting the voltage illumination. Automatically turn off the LED light function, eliminating the need for human control.
5. Control working time
The pv solar power lighting system charge controller has an accurate timer inside. Users can set different working hours according to their needs.
