How to check and repair solar street lamp failure and the characteristics of the controller

　　 How to check and repair the solar street lamp's failure?　　1. First, check whether the controller battery indicator light is on. If it does not, check whether the connection line between the controller and the battery is off and the connection line is normal. Use a multimeter to check the battery voltage. The battery voltage is normal. Replace the controller.　　 2. Check whether the load indicator of the controller is on, and use a multimeter to check the output voltage to see if there is a voltage output. If there is no voltage output, replace the controller. 3. Check whether the voltage at the input terminal of the LED driver is normal, and check whether the fuse of the LED driver is intact. If the fuse is intact, use a multimeter to check whether the output voltage of the LED driver is normal. drive.　　Solar street lamp special-intelligent identification solar street lamp controller features: 　　1, multi-function, low-consumption eight-bit single-chip intelligent control, 12V, 24V intelligent automatic identification.　　2. The voltage of solar cells and storage batteries is controlled in sections to improve the conversion efficiency of solar cells and the service life of storage batteries.　　3. After the battery reaches the state, pulse charging is used to improve the conversion efficiency of solar energy and ensure the charging effect of the battery. When the battery is full, stop charging to prevent the battery from overheating and accelerating aging.　　4. Adopting non-contact switch technology, output control options in different periods, and high-precision temperature compensation. One-click operation to complete all settings.
