Setting the Functions of the Multifunction Relays
Qualified person
The multifunction relays of the master are preset in an SMA Flexible Storage System and cannot be changed.
In multicluster systems with Multicluster-Box 12 (MC-BOX-12.3-20), multifunction relays 1 and 2 in the master of the main cluster and multifunction relay 1 in slave 1 of the main cluster are set permanently.
Note the function of the multifunction relays in the following table during the electrical connection ( > Connecting the Components).
Table for configuring the operating modes of the multifunction relay (for your own notes):
Parameters | Multifunction relay | Value | Function/output |
|---|---|---|---|
Operating mode of the multifunction relay | Relay 1 of Sunny Island inverter/master | ||
Relay 2 of Sunny Island inverter/master | |||
Slave 1: Operating mode of multifunction relay | Relay 1 of Slave 1 | ||
Relay 2 of Slave 1 | |||
Slave 2: Operating mode of multifunction relay | Relay 1 of Slave 2 | ||
Relay 2 of Slave 2 |
Procedure:
The basic procedure for changing operating parameters is explained in another section ( > Changing Operating Parameters).
