The strictness of solar LED street lights on the working conditions of the controller

The actual operation of the solar LED street light controller, the general solar street light manufacturer will set up and debug the controller before leaving the factory, and implement the intelligent unattended work to realize the external access parameters in the debugging of the solar LED street light lighting system status.

　　 In order to fully meet the working requirements of the LED light source, the set parameters will be written into the data flash memory of the solar controller. Let the controller control the whole set of solar LED street light lighting system from time to time. In addition, the solar panel is also transferred to the storage battery through the solar controller when charging, so as to meet the night work of the lighting equipment.

　　 At the same time, when the battery is collecting voltage, the controller uses the PWM function to manage the charging of the battery. Implement open circuit protection for the battery. If the solar panel is normally charged, the controller will turn off the load to ensure that the load is not damaged. If it is not charged at night or when the solar panel is not charged, the controller will lose its instinct and there will be no signs of action.

　　 The entire set of solar LED street lamp lighting system overcharge protection is very important, these are all realized by the controller, when the charging voltage is higher than the protection voltage, the controller will automatically shut down the battery charging process; when the voltage drops When the voltage is maintained, the battery will float. Similarly, when the battery voltage is lower than the protection voltage, the controller automatically turns off the load switch to protect the battery from damage. Through the PWM charging circuit, the effectiveness of the solar panel charging system can be maximized, so as to truly improve the efficiency.

　　Solar LED street light controller can be used for reverse connection, overcharge and overdischarge of the battery. Load output control and detection are two load outputs. Each channel of output has an independent control system circuit design, so as to achieve perfect control requirements and perfect over-current short-circuit protection. Only with such a controller can the entire solar LED street light lighting system play a protective role and prolong the service life of the entire equipment.
