What is the reason why the solar street lights are not lit and how to solve it?

Solar street lights.

The factors that do not light up can be checked from the following points:

1. The light source is damaged.

Due to man-made or natural reasons, the light source is damaged, resulting in the solar street light system can not work, sometimes on, sometimes not bright, flickering, dimming, etc.

Solution: Overhaul or replace the light source.

2. The solar panel is damaged.

Solar panel. Don't connect any load in the sun, don't link the controller, just pull out the wires of the solar panel and connect it to the multimeter.

Test its voltage, because your system is a 12v system, so the voltage of the solar panel will definitely show higher than 12v under normal circumstances, and the domestic board of this system will generally use a solar panel with a working voltage of 18v, so its open circuit voltage.

It will be above 18V (empirical judgment should be around 18-21V).

The solar street light system does not work or does not work enough hours.

Solution: Replace the solar panels.

The positive and negative poles of the solar panel are reversed.

The solar street light system will only turn on once after installation, and when the battery runs out, the solar street light will never turn on again.

Solution: Swap the positive and negative poles of the solar panel.

3. The controller is set incorrectly.

Solar street light system does not work properly with led lights.

It is not bright when it is bright, it is not bright for enough time, it is not bright during the day and it is not lit at night, or it is always on.

Solution: Reset the controller and replace it directly.

The positive and negative poles of the battery are reversed, the contact is poor, the service life expires, the battery is damaged, etc., so that the battery can not work normally, and the voltage is too low.

The solar street light system can not work normally, the LED lights are not lit, the time is not enough, the brightness is not enough, and the time is not on.

Solution: Reconnect the battery, replace the battery, replace the battery head, repair the battery, or replace the battery directly.

4. The line is aging or the line is disconnected.

The solar street light system is not working properly, and the LEDs do not light up or flicker.

Solution: Reconnect the wires or replace them.

5. Artificially caused hardware damage to the solar street light system.

The solar street light system is not working properly.

Solution: Hardware repair or replacement of damaged hardware.

There can be a variety of reasons why solar street lights don't light up, and here are some common reasons and solutions::

1.Solar panel failure: The panels of solar street lights are a key component in converting solar energy into electricity. If the battery plate is damaged or aged, it will not charge properly, causing the street lights to not light up. The workaround is to replace the battery plate.

2.Insufficient battery capacity: The battery capacity of a solar street light determines its ability to store electrical energy. If the battery capacity is insufficient, it cannot provide enough power for the street lights at night, resulting in the street lights not lighting up. The workaround is to replace the battery with a larger capacity.

3.Controller failure: The controller of the solar street light is responsible for controlling the charging and discharging process, if the controller fails, it will not work properly, resulting in the street light not lighting up. The workaround is to replace the controller.

4.Luminaire failure: The luminaire of solar street lights is a key component in providing lighting. If the light fixture is damaged or the bulb burns out, it will not be able to emit light properly, resulting in the street light not lighting up. The solution is to replace the light fixture or bulb.

5.Solar street lights surrounding environmental problems: Solar street lights need sufficient sunlight to work properly, if there are tall buildings or trees around to block the sunlight, it will affect the absorption and conversion of light energy, resulting in street lights not lit.

The solution is to adjust the position of the street lights or clear the surrounding obstructions.

6.Poor weather conditions: In rainy weather or cloudy days in a row, solar street lights cannot get enough sunlight to charge, resulting in street lights not lighting up. The workaround is to increase the battery capacity or use backup power.

In conclusion, there may be many reasons why solar street lights do not light up, and it is necessary to carefully check and troubleshoot the fault point, and then take corresponding solutions. At the same time, regular maintenance and maintenance of solar street lights is also an important measure to ensure their normal operation.

If there is no problem with the installation site, we need to consider whether there is a problem with the LED light source. Generally, if the street lamp is partly bright and partly not lit, we can preliminarily rule out the problem with the bulb of the street lamp, and we should be confident to see if there is a problem at the interface of the street lamp, and if there is a problem, then we must overhaul it as soon as possible.

If the solar street light does not light up, you need to check whether the lamp beads are burned, the battery is dead or the wiring is a problem.

Solar street lights are used for outdoor lighting, often encountering high temperature and rain, low temperature rain and snow weather, and the solar street light controller is usually installed in the light pole, which is easy to cause its water ingress to the controller short circuit.

First of all, observe whether there is water stains and rust at the terminal of the controller, if there is a high probability that the controller has been damaged, and the battery voltage is not measured, such as the 12V solar street lamp power supply system, the battery voltage is lower than the battery has no power storage, and it needs to be replaced. Then check whether there is voltage and current output under the normal working condition of the folding panel.

No just battery plate is damaged, replace the battery plate. All of the above is no problem, you should check the light source, only connect the power supply to the light source, see if it is lit, and replace the light source if it is not bright.

Extended Materials. The working principle of the solar street lamp system is simple, that is, the solar panel made of the principle of photogenerated volt effect, the panel receives solar radiation energy and converts it into electrical energy during the day, and is stored in the battery through the charge and discharge controller, when the illumination gradually decreases to the set value at night, the sunflower solar panel open-circuit voltage is about and around, and the charge and discharge controller automatically detects this voltage value and issues a braking command, and the battery begins to discharge the lamp head.

After the battery is discharged for hours, the charge and discharge controller issues a braking command, and the battery discharge ends.

1. If the solar street lamp only works until the second half of the night, it will get darker and darker, and there is no need to worry about this situation, which may be caused by the power of the solar street lamp being adjusted to half power in the second half of the night. Because people in rural areas have little entertainment at night and go to bed earlier, there are usually few people and cars passing by on the road in the second half of the night. Therefore, many manufacturers will set the power to light up in the middle of the night to reduce the solar street lights**.

Second, in the event of continuous cloudy rain, the solar street lights are getting less and less bright, so there is no need to worry too much. This is caused by insufficient solar energy absorbed by solar panels. Generally, street lamp manufacturers and solar street lights can ensure that the lights are on for 3-5 days on rainy days.

When the weather is clear, the solar lanterns will return to their normal brightness.

3. The solar panels are blocked. For example, the branches or other obstructions next to the solar lamp cover the solar panel, affecting its absorption of sunlight, which will also cause insufficient brightness. In the same way, if the leaves fall in autumn and the snow covers the solar panels in winter, they should also be cleaned up in time.

Here, Baoding solar street lamp manufacturers remind everyone to install solar lights in the countryside must be on the spot to avoid all obstructions such as surrounding buildings or plants affecting the lighting effect.

Answer: First of all, check whether the load indicator of the solar street light controller is lit, and use a multimeter to detect the output voltage to see if there is a voltage output. If there is no voltage output, replace the controller.

Secondly, whether the voltage of the input terminal of the solar street lamp drive is normal, check whether the fuse driven by the solar street lamp is intact, if the fuse is intact, use a multimeter to detect whether the output voltage of the solar street lamp drive is normal, if it is normal, please change the solar street lamp head, if it is not normal, please change the solar street lamp drive.

In addition, it is necessary to check whether the battery indicator light of the solar street light controller is lit, if it is not lit, check whether the connection line between the controller and the battery is off, the connection line is normal, use a multimeter to detect the battery voltage, the battery voltage is normal, and replace the controller. However, under normal circumstances, the best solar street lamps rely on sunlight to work, and basically do not need any repair throughout the year. Finally, the cost-effective solar street lamp is still recommended to Huangchuan Limin Science and Technology Street Lamp Factory to customize one-to-one according to your situation, customized under the same quality, ** is relatively favorable.

The solar street light system is not working properly. Solution: Hardware repair or replacement of damaged hardware. Have a great day!

1. It may be caused by damage to the bulb.

2 may be because the circuit board is not enough power, or the battery board is damaged, etc. 3 may be because the positive and negative poles of the battery board are not connected correctly 4 may be because of the phenomenon of open circuit, or the line connection position is loose, resulting in many reasons why the solar lamp is not lit, so we must find the solar lamp ** problem, we must maintain the solar lamp daily,

For example, if there is a lamp with a switch button, press and hold the no off switch button for 3-5 seconds to turn on the light.

It may be due to the damage of the solar controller, and at this time, the solar thermostat needs to be replaced in time. It is also possible that the positive and negative poles of the battery are reversed, or it is caused by poor line contact.

1. First of all, it is necessary to check whether the contact of solar energy is good, and secondly, to check whether the solar battery has water ingress. Some batteries are too poor in quality and not waterproof, and once water enters, it will cause short circuits in the positive and negative electrodes, and it will also cause voltage instability.

2. Check whether the solar line is aging or disconnected, and at this time, the line needs to be carefully checked. If the solar lights don't come on, and the system doesn't work properly. Then reconnect the wires. Secondly, it is also possible that solar panels are also possible.

Damage occurs. 3. Check the thermostat of solar energy, generally when solar energy is used, the red light indicates that it is charging. If it's a yellow light.

It means that there is a loss of electricity. If the battery is normal. The entrance may be inferred that there is a problem with the solar thermostat, and at this time, the solar thermostat needs to be replaced in time.

4. It is also necessary to maintain and maintain solar energy regularly. Regularly clean the solar pipes and dirt. Add a certain percentage of solar cleaner and water to the solar tank for soaking.

It takes about 5-15 minutes to easily remove limescale from solar energy.

The reasons why solar street lights do not shine are damaged solar cells, damaged solar controllers, and aging lines.

The reasons and solutions for the lack of solar energy are as follows:

1. Damage to solar cells: Solar street lights use lithium batteries or lead-acid batteries, and the batteries have a certain service life, and the batteries will be damaged after being used for too long, so that the solar street lights are not lit.

Solution: Try to choose a lithium battery with a long service life during installation, and constantly maintain and protect it during use, and replace the new battery in time after a certain period of use.

2. Damage to the solar controller: The solar controller is damaged by wind and rain, or because of other reasons, resulting in the controller not being able to operate normally.

Solution: Replace the new controller in time, Yanjing should remove the original controller, and then choose the same model matching controller, and debug.

3. Line aging: Line aging is the most common way of damage, and it cannot be used continuously after aging.

Prudent way to solve the problem: pay attention to the maintenance and maintenance of solar street lights.

The service life of solar street lamps has great advantages compared with other lamps, but this does not exclude damage caused by improper use or external factors, because solar street lamps are used for outdoor lighting, they often encounter high temperature and rain, low temperature rain and snow weather, and the solar street lamp controller is usually installed in the light pole, which is easy to cause its water ingress to the controller short circuit. If the whole lamp is not lit once there is a situation, Weifang Chengyuan Road Lamp Factory suggests that you can start from the following aspects to investigate: observe whether there is water traces and rust at the terminal of the controller, if there is a very trapped, the sensitive energy controller has been damaged; Then carry out battery voltage measurement, 12V solar street lamp power supply system, the battery voltage is lower, then the controller can not start normally and the solar panel can not charge the battery through the controller, dig out the battery, through manual charging, after the battery voltage is full, and then install, find a sunny day, directly connect the positive and negative poles of the battery with the positive and negative poles of the solar panel (not through the controller) 1 hour to remove, and then connect the Wang ridge branch controller respectively, and then check the Hongyixiang battery board, Under normal working conditions, there is no voltage and current output in the field.
