The solar battery is composed of solar panels, solar control panels, battery packs, light sources, street lamps, and lighting fixtures. The solar battery is divided into lithium batteries and colloidal batteries. Lithium batteries have the advantages of long lifespan, environmental protection, and high specific energy ratio, and are widely used in the field of solar energy LED street lamps. Below, I will take everyone to master the lithium battery solar street lamp. If there is a problem, how should everyone check it 1. Check if the surface of the rechargeable battery is clean and there is a leakage of corrosion-resistant liquid. If there is a lot of waste in the casing, wipe it with a damp cold cloth dipped in soap powder 2. Check if the appearance of the charging battery is dented or swollen

3. At least once every six months, the tightening work of the individual interconnected screws of the battery should be carried out to prevent loosening, resulting in poor contact and other common faults. When maintaining or replacing lithium batteries, special tools such as wrenches must be equipped with insulation sleeves to prevent short circuit faults 4. After charging and discharging the battery, it should be immediately charged. If it continues to rain for several days, resulting in insufficient charging of the battery, the power supply system time of the power plant should be terminated or reduced to prevent overcharging and discharging of the battery. Power plant maintenance personnel should conduct balanced battery charging of batteries on time, usually 2-3 times per quarter. For batteries that have been out of use for a long time (over 3 months), they should be recharged before being put into operation 5. In winter, it is necessary to do a good job in insulation and natural ventilation of the battery room. In summer, the temperature of the battery room should be controlled between 5 ℃ and 25 ℃ as much as possible 6. Maintain the cleaning of the lighting surface of the LED solar street lamp array. In areas with low rainfall and heavy dust, cleaning should be done once a month. First, clean with cold water, and then wipe the water stains with a clean, soft cloth. Do not use corrosive organic solvents or hard blocks for cleaning. Cleaning should be carried out during periods without sunlight or sooner or later. It should be prevented from using cold water to clean the solar modules when they are heated by the sun during daytime, as very cold water can cause the glass cover of the solar modules to crack 7. Regularly maintain whether the wiring between solar street lamp components is sturdy, and whether the wiring in the matrix junction box is sturdy, and tighten it as necessary; Check if the solar LED street lights are damaged or abnormal, such as damage, fading of grid lines, heat spots, etc; Check if the bypass diode inside the solar module wiring terminal is working properly. When solar street lights encounter difficulties, they should be immediately replaced and detailed records should be kept of the actual installation locations of the components in the solar power generation array
