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.
• 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 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 Modbus® Interface" or "SunSpec® Modbus® Interface" at
www.SMA-Solar.com).

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 to
configure the inverter. When saving, only the device parameters will be saved, not any passwords.
Procedure:
1. Activate the user interface (see Section 8.1, page 44).
2. Log into the user interface (see Section 8.2, page 47).
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.
9.6
Adopting a Configuration from a File
To configure the inverter, you can adopt the configuration from a file. To be able to do this, you
must first save the configuration of another inverter in a file (see Section 9.5 "Saving the
Configuration in a File", page 56). When saving, only the device parameters will be adopted, not
any passwords.
Requirements:
☐ The SMA Grid Guard code must be available (see "Application for SMA Grid Guard Code"
at www.SMA-Solar.com).
☐ Changes to grid-relevant parameters must be approved by the responsible grid operator.
