The first situation: the light of the solar street lamp flickers and the brightness is unstable.
< br >
This phenomenon, first of all to determine whether the problem of the lamp head, change the lamp head try, if the replacement of the lamp head or flashing, you can be sure that it is not the problem of the lamp head, this time to check the line, the line interface contact poor night will lead to this situation.

The second situation: solar street lights can only persist for a day or two on rainy days.
< br >
The main reasons for this phenomenon are the following two points, 1. Solar battery charging dissatisfaction, solar battery charging dissatisfaction is the reason for solar charging, first of all, observe the recent weather conditions, whether it can ensure that the daily charge of 5-7 hours or so, if the recent rainy weather is more, the daily charge of only 2-3 hours such a situation is normal, It can be used normally when the weather improves. 2. Check whether there is aging of the solar battery. The life of the battery under normal working conditions is 8-10 years.
First, if the sun is not very good, such as rainy days, especially before and after the Qingming Festival of the year, the sun is not enough.

Second, after solar street lights have been installed for a few years, the power generation of solar panels began to regress, and the power generation was significantly less.
< br >
Third, after the solar street lamp has been used for a few years, the battery begins to age and leak, the storage power is less, and the time of the street light will become shorter.
This situation may be that the photoelectric board power is too small, the charging current is less than the consumable current, there is another reason, it may also be the internal circuit board is broken, it is recommended to replace the circuit board.
