Possible failures of led solar street lights
The led solar street light factory is endowed with many active meanings in its brilliance, which not only reveals the vitality and enterprising energy of the city, but also marks the blessings of Guotai, the people’s safety and prosperity in the prosperous age. The night of the city presents a colorful and charming landscape.
If the solar garden light has been installed and used normally for a period of time, the led solar street light manufacturer first checks the response of the controller’s indicator lights. If both indicator lights are off, the controller may have been damaged, and the system may be damaged. To strong current impact, such as direct lightning strike or short circuit.
If it is found that the controller indicator shows normal discharge at night, the battery has enough voltage, but the solar garden lamp does not light up, connect the positive and negative poles of the lamp directly to the positive and negative poles of the battery to test. If it cannot discharge, the lamp driver or rectifier It may be damaged.
The controller displays the undervoltage state, and does not light up after dark, but the battery voltage has exceeded the undervoltage value, indicating that the battery is charged. For a 24V system, the undervoltage protection value is about 22.2V (the default value of the controller). After the battery drops to this voltage point, the controller shuts off the power supply and stops discharging. The LED solar street lamp manufacturers mainly protect the battery from over-discharge.
The battery pack charges the battery during the day, and when the voltage reaches 24V (the default value of the controller), it will continue to discharge. The main purpose is to prevent the battery from being damaged by deep discharge. Then after the battery is undervoltage, if the controller is not restarted, the voltage between 22.2V and 24V is under-voltage, and the battery will continue to discharge until the battery voltage is charged above 24V.
