Chang Hui: How to reduce the probability of frequent failure of garden lights?

There are many reasons for the failure of solar garden lights. By summarizing the most faulty components and strengthening the daily maintenance and testing of the components, the probability of failure can be reduced. Let's first learn how to find the faulty components: 1. Inspection and control Check whether the indicator lights of the controller and battery are still on. If 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. If the battery voltage is normal, replace the controller. 2. Check whether the voltage at the input terminal of the LED driver is normal, and check whether the fuse of the LED driver is in good condition. If the fuse is in good condition, use a multimeter to check whether the output voltage of the LED driver is normal. If it is normal, please replace the LED lamp head. If it is not normal, please replace the LED drive. 3. Check whether the load indicator light of the controller is lit, and use a multimeter to detect the output voltage to see if there is voltage output. If there is no voltage output, replace the controller. However, 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. The garden light controller not only accurately controls the output current to ensure that the power of the lamp head is within the range of our design, but it can also monitor the status of the battery at all times. When the voltage of the battery drops, the controller immediately reduces the output current, the voltage of the battery continues to drop, the controller continues to drop the current, if the voltage of the battery 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 garden light controller resumes its normal working state. For details, please log in: www.chz-lighting.com.
