What happens when the load of the street lamp PV controller is not powered

It's becauseFusesproblems. Direct charging protection point voltage: direct charging is also called emergency charging, which belongs to fast charging, generally charging the battery with high current and relatively high voltage when the battery voltage is low, however, there is a control point, also called the protection point, which is the value in the above table.

When the terminal voltage of the battery is higher than these protection values during charging, direct charging should be stopped. The voltage of the direct charge protection point is generally the voltage of the "overcharge protection point", and the voltage at the end of the battery cannot be higher than this protection point when charging, otherwise it will cause overcharge and damage to the battery. ‍

Precautions: 1. Under normal circumstances, most manufacturers produce solar street lights.

The default number of rainy days is three days, and the number of rainy days of the integrated solar street lamp will be longer, as little as five days and as many as seven days. That is to say, within the specified number of days, even if the solar street lamp cannot supplement the solar energy, it can work normally, but once this number of days is exceeded, the solar street lamp cannot be used normally.

2. The reason why solar street lights can continue to work in rainy days is because there is a part of the battery that stores electric energy, and in the absence of solar energy conversion, street lights can also continue to work for a period of time, but when the original stored electricity is exhausted but can not be replenished by solar energy, the solar street lights will stop working.

A: There are several possibilities that the controller does not output:

1. The voltage at the end of the solar module is high, and the set light control point is not reached, so the controller has no output.

2. If the electrical load wiring is short-circuited or the load is overcurrent, the controller will automatically turn off the output.

3. The battery voltage is too low, and the controller is protected by low voltage.

4. If the temperature of the controller is too high, the controller is over-temperature protected.

All of these possibilities can cause the controller to be unable to power the load.

Generally acorns say solar street lights rarely have problems, due to the influence of all aspects, solar street lights will not light up and other phenomena, as a professional blind enterprise, when the street lights fail, we have to check from which aspects? (1) Check whether the indicator light of the solar controller and the battery is lit, if not, then see if the connection line between the controller and the battery is off, if the connection line is normal, use the multimeter to detect the voltage of the battery, if the voltage of the battery is normal, that is the problem of the controller, replace a controller to see if it is in normal use. (2) Then check whether the load indicator of the controller is lit, you can detect it with a multimeter, detect whether it has an output voltage, if there is no voltage output, replace the controller.

3) Finally, check whether the voltage of the LED drive input terminal is normal, check whether the fuse of the LED driver is not intact, if the fuse is played, use a multimeter to detect whether the output voltage of the LED drive is normal, if it is normal, change an LED head, if it is abnormal.

Summary. Hello, your question is being sorted out, please wait a moment and be patient.

Hello, your question is being sorted out, please wait a moment and be patient.

Hello, it means that the solar street lamp absorbs the solar energy and the silver rate is too poor, and the electric energy of the staring reputation is naturally poor, and the front will be used up purely and needs to be supplemented by the mains, so the choice of solar street lamps does not choose miscellaneous brands, and the brand has a good reputation. It is better to replace the battery plate.

The wire is broken, and the knot is tied immediately, and the light is not on? How to solve it?

Hello, check if the filament is broken.

The positive wire of the LED lithium battery is broken.

It needs to be replaced. What to replace?

Check whether the lithium battery box is burned out.

How to check? Check the voltage is.

See if the excuse burns out.

Whether the interface is burned out.

The voltage of the photovoltaic panel of the solar street light is 40 volts, the battery voltage is 29 volts, the blue light of the controller is flashing, and the upper light is not lit.

Hello, the voltage of the photovoltaic panel of the solar street light is 40 volts, the battery voltage is 29 volts, the blue light of the controller is flashing, and the solution of the upper light is not lit is 1First of all, check whether the connecting wire of the lamp board is damaged. 2.

Check whether the battery has a voltage output, if there is no voltage output, there is a problem with the battery, there is a voltage to open the orange output lamp board is not lit, the lamp beads on the sensitive lamp board may be burned out, you need to remove the lamp board to check! 3.If it is controlled by a remote control, it is necessary to check whether the infrared emission of the remote control works, regardless of whether it can be lit with a manual switch, if it can be lit manually, the remote control is damaged, if it can't, it is a check of the situation of appeal 1 2.
