Spare Parts
Spare parts can be identified via their reference designation and the circuit diagram. The spare parts list includes the
article numbers of each spare part. For information on a specific article number, contact the SMA Service Line.
Shorter maintenance intervals in the event of adverse ambient conditions
The location of the PV system and ambient conditions influence the maintenance intervals.
• If the inverter is installed in adverse ambient conditions, SMA recommends a monthly inspection in order to
determine the need for maintenance. The maintenance intervals are to be shortened depending on the
determined maintenance requirements. In particular, cleaning work and corrosion protection may be necessary
more frequently.
• Adherence to the maintenance intervals ensures trouble-free operation of the inverter (see the maintenance
report of the inverter).
