Accepting the settings
Saving the made settings is indicated by an hourglass symbol on the user interface. If the DC
voltage is sufficient, the data is transferred directly to the inverter and accepted. If the DC
voltage is too low (e.g. in the evening), the settings are saved, but they cannot be directly
transferred to or accepted by the inverter. As long as the inverter has not yet received and
accepted the settings, the hourglass symbol will continue to be displayed on the user interface.
The settings will be accepted when there is sufficient DC voltage applied and the inverter
restarts. As soon as the hourglass symbol appears on the user interface, the settings have been
saved. The settings will not be lost. You can log off of the user interface and leave the system.
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 SMAGridGuard Code" at www.SMA-Solar.com).
Procedure:
1. Access the webserver (see Section8.1, page43).
2. Log in as Installer.
3. On the right-hand side of the menu bar, select the menu User Settings (see Section8.3 "Start
Page Design of the User Interface", page47).
4. In the subsequent context menu, select [Start the installation assistant].
☑ The Installation Assistant will open.
9.3 Configuring the Country Data Set
By default, the inverter is set to a universally valid country data set. You can adjust the country data
set for the installation site retroactively.
The country data set must be set correctly.
If you select a country data set which is not valid for your country and purpose, it can cause a
disturbance in the PV system and lead to problems with the grid operator. When selecting the
country data set, you must always observe the locally applicable standards and directives as
well as the properties of the PV system (e.g. PV system size, grid-connection point).
• If you are not sure which country data set is valid for your country or purpose, contact
your grid operator for information on which country data set is to be configured.
The basic procedure for changing operating parameters is explained in another section (see
Section9.1 "Changing Operating Parameters", page51).
