6.3 Maintenance
Due to its design, the inverter is maintenance-free.
The cooling system is dimensioned in such a way that the inverter is optimally
protected from overheating over its entire lifetime. The fans are temperature-
controlled, running only when the system output is raised. The fan speed thus
depends on output.
If an inverter is installed in a dusty environment, the inverter will quickly become
dirty as a result of the air flow through the cooling fins.
If the cooling element becomes dirty, heat dissipation will be impaired causing
the output restriction at lower ambient temperatures than the 50 °C to
be reached more quickly and thus unnecessarily decrease the amount of electric-
ity generated.
It is recommended that the amount of dirt on the cooling element be checked reg-
ularly and that the ventilation grills and the ventilation duct be cleaned as needed.
Make sure that no objects cover the ventilation paths. If faults occur and you must
exchange the fans, please contact your installer.
The inverter casing can be cleaned with a damp cloth. Do not use any cleaning
agents that can damage the lacquered metal casing.
