8.12 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
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 Modbus® Interface" or in the Technical Information "SunSpec®
Modbus® Interface" 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 Modbus® Interface" or "SunSpec® Modbus® Interface" at
www.SMA-Solar.com).
