Solar garden led light is mainly used for road lighting. Assuming that you are not prepared when choosing a solar controller, you will not only fail to bring light to the road in the end, it will even cause energy and material damage. The fault detection method of solar garden led light:

First check whether the indicator lights of the solar controller and the battery are on. If it is not, then check whether the connection line between the controller and the battery has fallen. If the connection line is normal, use a multimeter to check the battery voltage, assuming the battery If the voltage is normal, that is the problem of the controller. Replace a controller to see if it is in normal use.

Then check whether the load indicator of the controller is on. Use a multimeter to detect whether it has output voltage. If there is no voltage output, replace the controller.

Check whether the voltage of the LED driver input terminal is normal, check whether the fuse of the LED driver is intact, if the fuse is good, use a multimeter to check whether the output voltage of the LED driver is normal, if it is normal, go to the street light The manufacturer changes a LED lamp holder, if it is not normal, then change a LED driver.
