9 Configuration
9.1 Configuration Procedure
Once you have commissioned the inverter, you may have to adjust various inverter settings. This
section describes the procedure for configuration and gives an overview of the steps you must
perform in the prescribed order.
No configuration via Sunny Explorer
Sunny Explorer does not support the configuration of inverters with integrated web server and
their own user interface. The inverter can be detected via Sunny Explorer, however it is
expressly not recommended to use Sunny Explorer to configure this inverter. SMA Solar
Technology AG does not accept liability for missing or incorrect data and possibly resulting
yield losses.
• Use the integrated inverter user interface for the configuration of the inverter.
Procedure See
1. Perform initial configuration with the help of the installation
assistant. Section 9.2, page 41
2. In order to receive control commands of the grid operator
via SMA Speedwire/Webconnect for PV systems in Italy,
set the parameters. Section 9.4, page 42
3. If the inverter is installed in an IT network or another grid
configuration where deactivation of the grounding con-
ductor monitoring is required, deactivate the grounding
conductor monitoring. Section 9.5, page 43
4. For partially shaded PV modules and depending on the
given shading situation, you should set the interval at
which the inverter optimizes the MPP of the PV system. Section 9.6, page 43
5. Make further settings where necessary.
9.2 Starting the Installation Assistant
The installation assistant leads you step-by-step through the steps necessary for the initial
configuration of the inverter.
Requirements:
☐ When configuring after completion of the first ten operating hours, 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 inverter user interface (see Section 8.1, page 34).
2. Log in as Installer.
