Solar traffic lights circuit diagram to explain why the lamp installation

A, detection, solar street light controller, the controller is the core of the solar street light. Said it was charging a red light, flashing said electricity has been full of, if it is a yellow light, said losing electricity, can't normal lights, now need to detect the battery voltage of solar street lamps, such as

first of all, the detection of solar street light controller, which is the core of the solar street light. Said it was charging a red light, flashing light said the battery is full, yellow light said power has run out, unable to normal light. At this point, the solar street light to check the battery voltage. If the battery is normal, please replace the new controller, and see if there is something wrong. If the normal, the basically determine the damage of the controller. If the light is not bright, check whether the wire fall off. Second, if the controller failure are excluded, the next step is to detect the solar panels can charge. In general, solar panels can't charge is mainly characterized by voltage and current. At this point, it is necessary to check whether panels connector welding. Connection is good, the aluminum foil on the panels without current, if there is no current, basically can be concluded that panels have been scrapped. If the current solar panels, also must pay attention to whether there is can't charge of snow. Third, the battery is also a part of the failure of easily. Many use battery is not waterproof, water will cause the battery is negative after short circuit, lead to voltage instability. Careful observation in the process of testing the battery. Traffic signal lamp accessories voltage changes with the depth of discharge. If you can't normal use, need to replace new one. Fourth, to check whether the line is damaged again. If the insulation layer and wear, the current through the light transmission, would lead to short circuit, the lamp will not be able to light up. By the way, some of the solar street light is very bright during the day. It won't close. In this case, the controller component may burn out. These are some of fault detection and maintenance solar street lamp, solar street lights maintenance is a professional working. Without permission, we should not assist maintenance solar street lamp, but should wait for maintenance personnel to repair.
