What are the reasons why the solar lights suddenly don t turn on?

The reason why the bulb does not light up: it may be that the lamp is damaged, the line is faulty, the switch control line has a broken point, and the switch is faulty. Burning out of the filament of the lamp will cause the lamp to not light up.

Solution: 1. First of all, it depends on the incandescent lamp or energy-saving lamp you use at home, if it is an incandescent lamp, it is caused by poor contact, if it is an energy-saving lamp, it may be caused by the unstable voltage in your home, mainly because the voltage is too low, or the contact of the line is poor, if it is not a normal power outage, the cause of the line should be found and dealt with.

2. Disassemble the bulb and eliminate the short-circuit factor; The switch can't really be closed, change it to a new one; The wire inside the plastic is broken, replace the wire.

3. You can swap the unlit lamp with the bright lamp to judge whether the filament is burned out.

4. Replace the bulb.

1. The controller of the solar street lamp is connected incorrectly.

For the lighting of solar street lights, it is generally controlled by the controller, if the solar street lights are not lit when they are on, the time of light is relatively short, they are bright during the day, they are not lit at night or they are always on, this problem is more obvious because there is a problem with the controller, and the answer is to reconnect the controller. If the solar street light controller does not have any indicator light on, the surface controller is faulty, and the corresponding controller should be purchased again.

2. There is a problem with the battery. For example, the positive and negative poles are reversed, the contact is poor, the service life expires, and the battery is damaged, resulting in the solar street lamp not working, and the voltage is relatively low.

Check whether the positive and negative poles of the battery are reversed, charge the battery with your own power supply, test the voltage normally after the 12V battery is fully charged, and then connect the battery directly to the load, test the voltage with a multimeter, and check the change of voltage. If the voltage decreases, the battery is normal. The solar street light system does not work normally, the LED light is not lit, and the time to light is not enough, the solution:

Reconnect the battery, replace the battery, and replace the terminal of the battery. Or simply replace the battery.

3. The line is aging or disconnected.

In this case, the circuit should be carefully checked, if the solar street light system is not working properly, the solar controller LED will not light up or flash. Reconnect the wires.

4. Damage to the components of the solar street light system (such as lamp holders, or solar panels).

If the parts are damaged, they should be repaired or replaced with new ones in time.

For solar street lights, if there is a failure, it will not be able to provide convenient lighting services for people, and the impact is great, so if there is a failure, it is necessary to troubleshoot the problem in time, and then solve it quickly. Hebei Changyuan Lighting has a deep understanding of all the details of solar street lamps to ensure that solar street lamps provide normal lighting services.

1. Detect the solar street lamp controller, which is the core of the solar street lamp. A red light indicates that it is charging, a flashing light indicates that the battery is fully charged, and if it is a yellow light.

If the battery is normal, then replace the new controller to see if it is normal, if it is normal, it is basically determined that the controller is broken. If the light is not on, detect whether the wiring has fallen off.

2. If the controller fault is ruled out, the next step is to inspect the solar panel.

Whether it can be charged, usually the situation that it cannot be charged is mainly manifested in the presence of voltage and no current. At this time, it is necessary to check whether the battery plate joints are welded well and the aluminum foil on the battery board.

If there is no current, if there is no current, it is basically concluded that the battery board has been scrapped. If solar panels.

There is an electric current on it, and also pay attention to whether there is snow cover that cannot be charged.

3. The battery is also a link that is prone to failure. The batteries used by many manufacturers are not waterproof, which leads to a short circuit between the positive and negative electrodes after the battery enters the water, resulting in unstable voltage. During the test, carefully observe the change of battery voltage with the depth of discharge, and replace it with a new one if it cannot be used normally.

4. Finally, check whether the line is damaged. If the insulation layer is worn and the current is conducted through the lamp pole, it will cause a short circuit and the lamp will not light up.

One is that the battery is not fully charged, and the other is that the light sensor switch automatically turns off when it detects high illumination.

Damage to the bulb.

If the solar light does not light up, flickering or does not light up from time to time, it may be the cause of the bulb, which may be naturally broken or man-made.

Damage to the battery.

If the battery is not overloaded under normal circumstances, we can use a universal test meter to test the voltage, usually the voltage is 12V, and generally will not exceed 12V.

There is no electricity in it, or the lamps and wiring are faulty.

It's hard to say.

It may be that there is no power, or there may be a problem with the circuit or circuit board. Only by checking it out can we know the cause and solve the problem.

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.

It may be caused by damage to the light bulb, it may be caused by insufficient power of the battery board or damage to the battery board, it may be caused by the positive and negative poles of the battery board are not connected correctly, or it may be caused by the opening of the circuit or the loosening of the line connection.

Hello, I'm glad to have your question, I've seen your question here, I'm helping you sort out the answer, please be patient, I'll be yours in five minutes!

1. It may be caused by damage to the bulb, or because the battery board is insufficient or the battery board is damaged, or because the positive and negative poles of the battery board are not connected correctly, or because the line is broken or the line connection is loose. 2. If it is caused by the damage of the bulb, then the damaged bulb should be replaced with a new one. If the battery is low or damaged, the battery should be replaced with a new one.

If the positive and negative poles of the battery plate are not connected correctly, the positive and negative poles of the battery plate should be reconnected correctly. 3. If the solar lamp does not light up because the line connection position is loose or disconnected, the line in the loose position should be reconnected, and the loose position should be wrapped tightly with adhesive tape, so as to avoid loosening again. 4. There are many reasons why the solar lamp is not lit, and the maintenance measures taken will be different for different reasons, so you must find the reason why the solar lamp is not lit first.

In order to ensure that the solar lanterns can be used normally, it is recommended that everyone must check and maintain the solar lanterns regularly.

If the solar lamp fails, it will not be able to provide users with convenient lighting services, affecting the normal use of users, so when the solar lamp is found to be faulty, we must find the cause of the failure of the solar lamp in time, and then take appropriate methods to deal with it according to the actual situation.

What is the reason why the solar lights are not on for a few days? When the rainy season comes, or it is always cloudy, there is not enough sunlight and enough electricity to charge the battery, the battery is "starving", the energy storage has run out, and you can only wait for good weather to replenish the electric energy. At present, most of the solar cells are not large enough, the battery capacity is relatively small, and the energy stored in a charge is too small, which is only enough for one day.

It can be opened during the day, but it cannot be opened at night.

The solar light is not on, this is because you have not used this solar light for a long time, and the solar energy storage battery is damaged.

If you don't check it, no one knows the reason, and I'm really looking forward to it

Hello, there may be several reasons why the solar light will not be on for a while:1Insufficient light:

Solar lanterns need to be charged to emit light, and if the location of the solar lantern orange hall is not lit enough to support night use, it will not be lit for a while. 2.Battery aging:

Solar lights use lithium batteries, and if the battery is aged or used for too long, the capacity of the battery will be reduced, resulting in insufficient charging to support nighttime use. 3.Bulb failure:

It is also possible that the bulb of a solar lamp may malfunction, causing it to be on for a while. 4.Solar panel damage:

The solar panels of the solar lamps may also be damaged, resulting in the inability to charge, resulting in a situation where they will not be lit for a while. In order to avoid the situation that the solar lights will not be on for a while, we can choose a well-lit location to install solar lights, replace the batteries regularly, check whether the bulbs are normal, and regularly check whether the solar panels are damaged. In addition to solar lights, solar energy can also be used in solar water heaters, Taiyuan hidden solar power generation and other local blue fields, which can bring more convenience and environmental protection to people's lives.

Summary. Hello dear and happy to answer for you. Found for you:

The reason why the solar light will not light up for a while is that the interface between the solar controller and the battery is not firm, resulting in poor contact with the solar lamp, and the street lamp is sometimes on and sometimes not on. Solar lamps use photovoltaic solar panels to collect sunlight, and when the stored power of the solar lamp is exhausted, the battery of the lamp cannot be connected to the AC grid for charging, and the power will be cut off. The efficiency of solar lamps in absorbing solar energy is too poor, and the converted electrical energy cannot be enough for the use of street lights, so the lights are sometimes on and sometimes not on.

I hope mine can help you and have a great day

Okay thanks, I'm waiting.
