In the previous article, we discussed the lifespan of solar streetlight batteries. In this article, we will learn about the inspection and maintenance of solar streetlight batteries.
How to check the solar streetlight battery
1. Check if the battery surface is clean and if there are any signs of corrosion or leakage. If the outer casing is dirty, you can clean it with a damp cloth and some laundry detergent.
2. Inspect the battery for any dents or swelling.
3. At least once every six months, ensure that the connection screws between battery units are tightly secured to prevent loosening, which may lead to poor contact and other faults. When maintaining or replacing batteries, tools (such as wrenches) used must have insulated handles to prevent short circuits.
4. Recharge the battery promptly after discharge. If there are consecutive days of rain, leading to insufficient battery charging, the power supply from the station should be stopped or shortened to avoid over-discharging. Maintenance personnel should regularly perform equalization charging of the batteries, generally 2-3 times a quarter. For batteries that have been unused for an extended period (over 3 months), they should be charged before being put back into operation.
5. In winter, ensure proper insulation of the battery room, while in summer, ensure good ventilation. The temperature in the battery room should ideally be maintained between 5℃ and 25℃.
6. Keep the solar panel array clean. In areas with little rain and high dust, clean the panels monthly. First, rinse with clean water, then use a soft, clean cloth to dry the water spots. Avoid using corrosive solvents or hard objects for cleaning. It is best to clean the panels in the early morning or late evening when there is no sunlight. Avoid washing the panels with cold water during the day when they are heated by the sun, as cold water can cause the glass cover of the photovoltaic panel to crack.
7. Regularly check if the connections between photovoltaic modules are secure, and if the connections within the junction box are tight, tighten if necessary. Check for any damage or abnormalities in the photovoltaic modules, such as cracks, missing busbars, or hotspots. Verify that the bypass diodes in the junction box of the photovoltaic modules are functioning properly. When there is a problem with the photovoltaic components, replace them promptly and thoroughly record the specific installation distribution of the components in the photovoltaic array.
Maintenance of solar streetlight batteries
1. Prevent rainwater from entering
The outer packaging of the battery must be tightly sealed to prevent rainwater from entering.
2. Stability during discharge and charging
During the charging and discharging process, there should be no signs of overly high or low voltage.
3. Temperature control
Every object has an appropriate temperature; it should not be too high or too low, so we must control the temperature.
4. Control of charging and discharging
This requires technical implementation, as the charging and discharging cycles of the battery are limited, and we should try to reduce the frequency of charges and discharges.
