Due to the continuous promotion of energy-saving concepts in various regions, solar street lights are now being applied to the streets and alleys. Although solar street lights rely on the conversion of solar energy into electrical energy, their service life is limited, and any problems must be repaired in a timely manner, otherwise it will cause inconvenience to people's lives. Each place will have dedicated inspectors to check if there are any abnormalities in the solar street lights. Next, I will take you to learn more in detail.
Firstly, you can judge by the HV and LV parameters of the solar street lamp battery in the past seven days. If one day the battery voltage is below 9.3V or the HV value is almost close to the value of the solar panel's no-load voltage, which is around 20 volts. If either of these two situations occurs, it indicates that the working condition of the solar street lamp has become abnormal.
If the battery voltage is within different ranges, it indicates that the reasons for the abnormality of solar street lights are different. For example, when the battery voltage is between 0-1V, there is a higher possibility of battery allergies. You can observe the recent weather conditions; The probability of battery damage is highest when the battery voltage is between 2-8.5V, and it is recommended to replace the battery directly.
In addition, the number of overcharging and discharging cycles of the solar street lamp battery can also be used to determine whether it has malfunctioned. In general, the number of over discharge times will not exceed the operating days of the solar street lamp. If it exceeds, it indicates that the solar street lamp is highly likely to have an abnormality.
Due to the fact that the remote control of solar street lights is infrared, the distance to receive parameters is also limited. Therefore, I suggest that everyone try to avoid reading parameters during the day.
