Visual inspection
Check the inverter and cables for any signs of external damage. Contact your installer if you find any
damage. Do not perform any repair work yourself.
Maintenance and Cleaning
Ask your installer to check for correct inverter operation at regular intervals.
If the inverter is dirty and the visibility of the operating data and operating states of the inverter is
limited, clean the enclosure lid, the display and the LEDs with a damp cloth. Do not use any corrosive
substances (e.g., solvents or abrasives) for cleaning.
