Maintenance of LED Solar Street Lamp Manufacturers'Street Lamp Products

Installation of outdoor LED solar street lamp has been in normal use for some time, encountered some minor problems, LED solar street lamp manufacturer teaches you small details of maintenance, check the response of the controller's indicator lamp, if the two indicator lights are not on, the controller may have been damaged, the system may be subject to strong current impact. Such as direct lightning or short circuit.

If the controller indicator shows normal discharge at night, the battery has enough voltage, but the lamp does not turn on. Connect the positive and negative poles of the lamp directly to the positive and negative poles of the battery for testing. If it cannot discharge, the driver or rectifier of the lamp may be damaged. The controller shows the under-voltage state and does not turn on the light after dark, but the battery voltage has exceeded the under-voltage value, indicating that the battery is electrified. In 24V system, the under-voltage protection value is about 22.2V. When the battery drops to this voltage point, the controller shuts off the power supply and stops discharging. The main purpose is to protect the battery from overcharging and overdischarging.

Battery panels charge batteries during the day. When the voltage reaches 24V, the batteries will continue to discharge. The main purpose is also to avoid the batteries being damaged by deep discharge. After the battery is under-voltage, if the controller is not restarted, 22.2V-24V will be under-voltage, and the discharge will continue until the battery voltage is over 24V.
