Data security during enabled Modbus interface
If you enable the Modbus interface, there is a risk that unauthorized users may access and
manipulate the data or devices in your PV system.
To ensure data security, take appropriate protective measures such as:
• Set up a firewall.
• Close unnecessary network ports.
• Only enable remote access via VPN tunnel.
• Do not set up port forwarding at the communication port in use.
• In order to disable the Modbus interface, reset the inverter to the default settings or
disable the parameter again.
Procedure:
• Activate the Modbus interface and adjust the communication ports if necessary (see the
technical information "SMA and SunSpec Modbus® Interface" at www.SMA-Solar.com).
8.18 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8.12 "Changing Operating Parameters", page69).
Parameter 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.
