With the progress of science and technology, solar street light has been widely used in road lighting, solar street light has the advantages of green, energy saving, safety and so on. However, in the practical application process, there are often some problems. Is there a problem? Let's find out some common questions and explore them with us. Controller FAQ for detecting solar street lamps will be equipped with controllers on top. Each controller has three indicators, representing the solar panel, solar battery and light source.
During the day, the first indicator blinks slowly to indicate that the solar panels are being charged, and the second indicator is always on to indicate that the solar cells are accumulating. When night falls, the controller's second and third indicators are always on, indicating that the battery is discharging to the lamp cap and the street lamp is properly illuminated.

The detection of solar panels plays a role of collecting light energy. If there is a problem, the whole solar street lamp cannot work normally. There are two common problems: the connection line is disconnected or the positive and negative poles are connected in reverse. Under the condition that the street lamp has been installed well, the two lines of the solar panel can be touched at the access door. If the spark represents the normal charging of the solar panel, the positive and negative terminals only need to be inverted. If there is no spark, it means that it cannot be charged normally, so it needs to put down the lamp pole and repair the connecting line.
Light source is a common problem detection in the controller and the panels during normal operation, find the light not bright, still want to see the light on the controller status, if the first two light is normal operation, the third indicator light flash, indicates the positive and negative connect the lamps and lanterns, switching from cohesion, such as lamp holder can normal light, can normal operation. If lamp cap cannot shine normally, illuminant presented a problem namely, demand new illuminant undertakes to replace.
Solar street lamps use low-voltage wires, each of which is made up of several thin copper wires. In the process of installation, there will be two conditions. First, no trace can be seen on the broken surface of copper wire inside the insulation layer. At this moment, as long as the voltage and no current pass through, the light source will no longer shine after the electricity consumption in the battery is exhausted. Second, the insulation layer was broken, the internal copper wire was not broken, the lamp pole conduction formed a short circuit, the light source still can not shine normally.
Battery common problems In operation, the controller indicator on the battery should be steady on. If three lights flash together, it indicates that the battery is in severe power deficit. If the detection battery voltage is more than 12 volts, after the connector lamp voltage drops rapidly, it indicates that the battery has been damaged; If the situation of severe power loss, battery positive and negative terminals in the collision is not spark.
There are two reasons why solar streetlights still shine well during the day. One reason is that the solar panel does not charge the battery by the controller during the day, and the solar panel and the controller are detected in one or two ways. Cause 2: The controller was faulty during connection, and the positive and negative terminals were connected, causing the controller components to be damaged. These are some problems that often occur in the use of solar street lamps.
