Operating manual SHP-US-20-BE-en-10 55
Procedure:
• In the parameter group Grid monitoring > Grid monitoring select the parameter Set
country standard and set the required country data set.
9.9 Configuring the Modbus Function
The Modbus interface is deactivated by default and the communication ports 502 set.
In order to access SMA invertes with SMA Modbus
®
or SunSpec
®
Modbus
®
, the Modbus interface
must be activated. After activating the interface, the communication ports of both IP protocols can
be changed. For information on commissioning and configuration of the Modbus interface, see the
technical information "SMA and SunSpec Modbus® Interface" at www.SMA-Solar.com.
For information on which Modbus registers are supported, see the technical information "Modbus®
parameters and measured values" at www.SMA-Solar.com.
Data security during activated Modbus interface
If you activate 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 deactivate the Modbus interface, reset the inverter to the default settings or
deactivate the activated 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).
9.10 Saving the Configuration in a File
You can save the current configuration of the inverter in a file. You can use this file as a data
backup for this inverter and then import this file into this inverter again or another inverter from the
same type or device family to configure the inverter. When saving, only the device parameters will
be saved, not any passwords.
Procedure:
1. Activate the user interface (see Section 9.1, page 46).
2. Log into the user interface (see Section 9.2, page 48).
3. Select the menu
Device Configuration .
4. Select [ Settings ].
5. In the context menu, select [ Saving the configuration in a file ].
6. Follow the instructions in the dialog.
