Reduce the possibility of failure of solar LED street lights to stabilize lighting

There are many reasons for the failure of solar LED street lights. By summing up the most faulty components, strengthening the daily maintenance and testing of the components, to reduce the probability of failure, let’s first understand how to find the faulty components: 　　1, check and control Whether the indicator light of the battery and the battery is still on, if it is 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 voltage of the LED driver input terminal is normal, 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, if it is normal, please replace the LED lamp cap, if not, please replace the LED drive.　　 3. Check whether the load indicator of the controller is on, and check the output voltage with a multimeter to see if there is a voltage output. If there is no voltage output, replace the controller.　　 Considering the cost factor, it is impossible to increase the configuration, and to ensure that the system is stable for a long time without turning off the lights, the key factor is still on the controller. Choosing a good controller is very important to the stability of the system. The automatic power reduction constant current controller used by our company has solved the problem for customers. This controller is a fully intelligent controller.　　 Solar LED street light controller not only accurately controls the output current, to ensure that the power of the lamp holder is within the range of our design, it can also monitor the state of the battery at all times. When the battery voltage drops, the controller immediately reduces the output current, the battery voltage continues to drop, and the controller continues to drop the current. If the battery voltage reaches the warning value, the controller immediately cuts off the output to protect the battery. When the weather improves and the battery voltage rises, the controller resumes its normal working state.
