Solar street light green

Now many are all LED solar street lamps, it replaces the traditional public power lighting lamps. No laying of cables, without ac power supply, do not produce electricity; Use dc power supply, photosensitive control; Has a good stability, long service life, luminous efficiency

at present, many are all LED solar street lamps, replaced the traditional public lighting lamps. Do not need to laying cable, do not need the ac power, do not produce electricity; The DC power supply and photosensitive control; The present invention has good stability, long service life, high luminous efficiency, simple installation and maintenance, high safety performance, energy conservation, environmental protection, economic and practical advantages. However, relatively easy to failure. What is the failure of LED solar street lamps, how should handle?

if you have installed and normal use for a period of time, first check the response of the controller lights. If the two indicator is on, the controller may be damaged, the system may be hit by heavy current such as direct lightning or short circuit. If found the light on the controller display normal discharge at night, and have enough battery voltage, but the light is not on, the light of the positive and negative directly connected to the positive and negative of the battery test. If you can't discharge, solar street lamp drive or rectifier may be damaged.

controller shows undervoltage state, after dark is not bright, but the battery voltage is more than under voltage value, indicates that the battery has electricity. For 24 v systems, under-voltage protection values of about 22. 2 volts ( The controller default) 。 When the battery down to the point voltage, the controller shut off the power and stop discharging, mainly in order to protect the battery is not excessive discharge. Panels to recharge the battery during the day, and only when the voltage is charging to 24 v ( The controller's default value) Will only continue to discharge. Main purpose is to prevent cell damage due to long time depth discharge. After then, if the battery voltage controller no restart, 22. 2 v - Between 24 v and 24 v voltage of undervoltage, will not continue to supply solar street lamps, until the battery voltage higher than 24 v. 。

when the solar street light is not bright, the first thing we need to do is check the cause of the failure, and then repair it. Don't assume that because solar street lamps not bright and scrap.
