there are many reasons for the solar street light is in failure, by summing up the failure of most components, strengthen the daily maintenance and inspection of the part, to reduce the probability of failure, the first to get to know how to find out the fault components: check whether the controller and the battery indicator light is still bright, if not bright check off, controller and battery cable connecting line is normal, the multimeter test battery voltage, battery voltage is normal, replace the controller. Check whether the voltage of the LED driver input is normal, check the LED driver, the fuse is in good condition, if the fuse intact, multimeter is used to inspect the LED driver output voltage is normal, if normal, please follow change LED lamp holder, if abnormal, please follow change LED driver. Check whether the controller load indicator light is lit, the multimeter is used to inspect the output voltage, see whether there is voltage output, if there is no voltage output, replace the controller.
