SMA Solar Technology SUNNY BOY 3.0, Operating Manual, Page: 58 / 100

Procedure:
• To switch on the WLAN direct connection, in the parameter group PV system
communication > WLAN , select the parameter Soft-access-point is turned on and set this
to Yes .
• To switch on the WLAN connection in the local network, in the parameter group System
communication > WLAN , select the parameter WLAN is turned on and set this to Yes .
9.9 Switching the Dynamic Power Display Off
As standard, the inverter signals its power dynamically via the pulsing of the green LED. When
doing so, the LED flashes on and off uniformly or is permanently lit at full power. The various
gradations are related here to the set active power limit of the inverter. If this display is not desired,
switch this function off in accordance with the following procedure. Once this has been done, the
green LED is lit permanently to signalize feed-in operation.
The basic procedure for changing operating parameters is explained in another section (see
Section 9.1 "Changing Operating Parameters", page 53).
Procedure:
• In the parameter group Device > Operation , select the parameter Dynamic power
display via green LED and set this to Off .
9.10 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 9.1 "Changing Operating Parameters", page 53).
Parameters Value/range Resolution Default
Application ID 0 to 16384 1 16384
GOOSE-Mac address 01:0C:CD:01:00:00 to
01:0C:CD:01:02:00
1 01:0C:CD:01:00:00
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.
