Repair and maintenance

  • Regularly check the panel for damage, ensure timely detection, timely replacement.
  • Regularly check solar system cable and ground connection is good.
  • Periodically check solar mounting structure have loose or broken phenomenon.
  • Check and clean-up the covering around the panel and surface with clean water and gauze, do not rinse with hard or corrosive solvents
  • In case of gale, heavy rain, rainstorm, hail, heavy snow and so on, measures should be taken to protect the solar cell module from damage.
  • After the gale, heavy rain, heavy snow or rainy season, immediately check whether solar panel displace, controller and battery box exist water, and thunderstorm after check whether the device is working properly, its charge and discharge controller is damaged, etc. .
  • Batteries used in matching with solar modules should strictly accordance with the battery maintenance instructions and methods.
