Daily maintenance items of off-grid solar cctv power supply
In order to keep optimal long-term performance, it is recommended to check the following items.
● Check all exposed wires for insulation damage caused by sunlight, friction with other objects around, dry rot, insects or rodents. If there is any damage, repair or replace the lead in time.
● Check all terminals for signs of corrosion, insulation damage or burning/discoloration, and ensure terminals are tightened.
● Check for dirt, nesting insects or corrosion, and clean up in time if any of the above conditions exist.
● Check whether the lightning arrester is invalid. If the arrester is invalid, replace it in time to prevent the controller or other devices from being damaged by lightning.
● In some specific areas with special weather conditions, necessary maintenance is needed to ensure the normal operation of the system. For example, in dry and dusty areas with little rain, a lot of dust will accumulate on the solar panels, affecting the power generation efficiency of the system; In cold, snowy, frozen regions, solar panels can be covered in snow and ice, resulting in reduced or no power generation. Therefore, solar panels should be cleaned of dust regularly. Snow generated snow must be cleared in time.
● Check the growth of plants around the system regularly to see if there is a block on the solar panel. If there is a block, clean it in time.
● According to the use of the battery, every 35 years, replace the performance of the degraded battery.
