Solar street lamps common faults

1, solar street light out of a complete set of solar street lights are not bright, of a complete set of the possible reasons have wiring is not correct, there is something wrong with the light source, line feed water controller circuit, such as continuous rainy days are too long. First check the solar street light controller, have a look at the logo above the

1, solar street light out of a complete set of solar street lights are not bright, of a complete set of the possible reasons have wiring is not correct, there is something wrong with the light source, line feed controller circuit, continuous rainy days is too long, etc. First check the solar street light controller, see the identity of the above, corresponding identification line detection is properly connected, whether there is water rust again observe the terminal of the controller, if you have most likely controller is damaged, if not, measure the battery voltage, the 12 v battery voltage is lower than 10 solar street light system. 7 v battery cannot use, replace the battery. Sunny sun, detection of solar panels if there is a current and voltage output, if you have the solar panel is normal, no damage to the solar panels. If all problems above does not exist, the problem is the led lamp light source, light source and other power supply connection testing, look to whether bright light, no light, in a light source of lamps and lanterns. Continuous several rainy day, if it is a complete set of solar street light is not bright is normal, because the solar panels is not power, the power stored in the storage battery has been depleted, such as sunny day lighting, solar panels continue to battery, solar street lamp lights will be normal. 2, light flashing led light flashing led lamps and lanterns, the main reason is the line connection problem, also may be battery lost electricity. First, check whether the line connection is correct, each node is connected and the parcel is normal, also can put the lines are to meet again, twinkle light source or consider battery lost electricity. The open circuit voltage of battery is measured with dc voltage, the voltage is lower than 12 v, is deficient electric battery, the battery is the cathode and anode properly connected solar look, charging 1 - 2 days system can be normal use. 3, bright bright time is short, rain will not appear this kind of failure is only one reason, battery capacity is too small, if it is a new installation, show the battery capacity of hair qi, can not meet the lighting requirements of continuous rainy days, if the solar street lamps have been used for several years, attenuation to the service life of the battery, replace the battery.
