The Sunny Central, the string monitoring units and the communication units must be maintained at
regular intervals. Maintenance includes the following activities:
• Inspection of wearing parts, and replacement if necessary
• Functional test of components
• Inspection of contact joints
• Cleaning of cabinet interior, if necessary
A maintenance protocol is enclosed with every Sunny Central. The maintenance protocol describes
the maintenance work to be carried out and the maintenance interval recommended by SMA Solar
Technology.
3.1 Identifying the Sunny Central
