Common problems with solar street lamps.

Solar street lights are widely used in modern urban and urban construction, and a complete set of solar panels, solar street light sources, batteries, controllers, lamp poles and armored lines, etc. To the operation of the solar street light is in the outdoor environment conditions, so can appear many unforeseen problems, and these problems may be only one small problem, but let the user very headache, in addition to professional and technical personnel can timely treatment, but others do. Today we ten years as a professional production - dongguan sea ray solar street lighting co., LTD., co., LTD., to teach you how to solve some common fault, in a nutshell, don't let the professionals can easily deal with common faults of solar street light, become a solar street lamp can deal with common problems of the old driver.

1. Controller detection: the controller's red light indicates that it is charging, the red light flashing indicates that the battery is full, and the controller is charging with the small current of the pulse.

2, controller, yellow light: indicates that the battery has lost electricity, can't normal lamp, at the moment, such as cell line disconnect and lit up, and then the controller test cell is after a day of costs and increase the battery capacity, not battery voltage floating (assembly) disconnect the load voltage.

3. Solar panel: the connection of solar panel is not very strong, it can form abnormal charge, usually the performance is voltage (voltage meter test), normal open circuit voltage is over 17.5 v; But there was no electricity. This kind of phenomenon in the case of no cohesion, there's not a good rendering, welding, welding or joint were not strong enough), in black open electric cooker, direct voltage, ampere meter testing data, can be directly behind the panel for testing. If the aluminum on the panel has no current, the panel has a problem to replace.

Solar street lamps in normal circumstances, battery, battery charging and discharging should be normal, such as more than 12 v test voltage, in a short period of time after the downward pressure connection lamp (load) voltage battery damage; Other battery formation water is negative when the waterproof shell, short circuit and detect the correct voltage is usually instantaneous high voltage, instant, low voltage, because too much water to form the battery discharge voltage less than 10 v, after the normal circulation of small current charge and discharge the battery, if can be normal use, if not normal use need to be replaced, normal for lead-acid battery capacity decline in three years will be by far the cuts ahead of time to turn off the lights may be rainy day time of day, now is normal phenomenon.

Led light source, under the battery voltage condition, the light source is normal operation, if the light is not bright, directly to the positive and negative pole of the lamp to check the cathode, the battery is like the light source can be lit; The lamp is good, the controller does not provide the lamp. The phenomenon is: rainy day time is long, the battery voltage is not enough, (controller to protect the battery voltage of 11.3 V and 11.3 V, is slightly lower than the battery voltage, the controller will be forced to turn off the lights) after a full battery is necessary to wait; When the voltage rises to 12V(24V), the lamp may not work properly. Lamps and lanterns is directly connected to the battery is not bright, that there is a problem of the lamps and lanterns, this phenomenon should be: adjusting control circuit control component with lamps and lanterns (large current, voltage collapse may components decrease), the state will contact the factory to replace.

The light of day is bright: the light of day is bright; This shows that solar panels and controllers can be detected in one or three ways in a single day without a controller charging the battery. 2. When the controller is connected to the negative pole, the components of the controller are destroyed.

The line is broken: because the solar street lamp USES the "low voltage line", each cable is made up of many fine copper wires. When we accidentally press the copper wire in the insulation layer, we can't see it, but through the current, the voltage can only be a few days later (no electricity, no current runs out of the battery). In addition, in the equipment, the insulation layer of the line is broken, the circuit is transmitted through the lamp pole, and the circuit is short-circuited.
