Changing Operating Parameters
This section describes the basic procedure for changing operating parameters. Always change
operating parameters as described in this section. Some function-sensitive parameters can only be
viewed and changed by qualified persons (for further information on changing parameters, refer to
the manual of the communication product).
The operating parameters of the inverter are set to certain values by default. To optimize inverter
operation, you can change the operating parameters using a communication product.
Requirements:
☐ Depending on the type of communication, a computer with Ethernet interface must be
available.
☐ A communication product corresponding to the type of communication used must be
available.
☐ The inverter must be registered in the communication product.
☐ The changes to the grid-relevant parameters must be approved by the responsible grid
operator.
☐ When changing grid-relevant parameters, the SMA Grid Guard code must be available (see
"Application for SMA Grid Guard Code" at www.SMA-Solar.com).
Procedure:
1. Call up the user interface of the communication product or software and log in as
Installer
or
User
.
2. If required, enter the SMA Grid Guard code.
3. Select and set the required parameter.
4. Save settings.

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