8 Operation
8.20 Activating the Receipt of Control Signals (Only for
Italy)
In order for PV systems in Italy to receive control commands from the grid operator, set the
following parameters.
The basic procedure for changing operating parameters is explained in another section (see
Section 8.14, page 77).

Application ID
GOOSE-Mac address 01:0C:CD:01:00:00 to
Procedure:
1. Select the parameter group External communication > IEC 61850 configuration.
2. In the field Application ID, enter the application ID of the grid operator gateway. You will
receive this value from your grid operator. You can enter a value between 0 and 16384. The
value 16384 indicates "deactivated".
3. In the field GOOSE-Mac address, enter the MAC address of the grid operator gateway
from which the inverter is to receive the control commands. You will receive this value from
your grid operator.
☑ The receipt of control signals from the grid operator is activated.

8.21 Setting SMA ShadeFix

You can set the time interval in which the inverter has to determine the optimum operating point and
to optimize the MPP of the PV system. If you do not want to use SMA ShadeFix, you can disable
the feature.
The basic procedure for changing operating parameters is explained in another section (see
Section 8.14, page 77).
Procedure:
• In the parameter group DC-side > DC settings > SMA ShadeFix, set the parameter Time
interval of SMA ShadeFix and set the required time interval. The ideal time interval is
usually 6 minutes. This value should only be increased if the shading situation changes
extremely slowly.
• In order to disable the SMA ShadeFix feature, in the parameter group DC-side > DC settings
> SMA ShadeFix, set the parameter SMA ShadeFix switched on to Off.
