If your inverter's information panel is not displaying a Fault light, check the
following list to make sure that the present state of the installation allows proper
operation of the unit.
8.2 Routine Maintenance
● Inverter
Inverters need to be checked every 12 months . (once per year)
Clean the housing with a dry cloth and check that there is no airflow obstruction.
Remove any dust build-up from the locations as indicated. Check the inverter
and the cables for visible external damage on regular basis.
Clean the airflow holes inside the housing, and cut off the power
from the inverter by decommissioning or by using a bypass switch.
Internal cleaning is only to be carried out by certified persons.
Contact your installer/dealer if you find any defects. Do not perform
any repair work by yourself.

• Are the cables adequately sized and short enough?
