8.11 Changing Operating Parameters
The operating parameters of the inverter are set to certain values by default. You can change the
operating parameters to optimize the performance of the inverter.
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 by qualified persons and can only be changed by qualified persons by entering the
personal SMA Grid Guard code.
Requirements:
☐ Changes to grid-relevant parameters must be approved by the responsible grid operator.
☐ Changes to grid-relevant parameters must be approved by the responsible grid operator.
Procedure:
1. Activate the user interface (see Section 8.1, page 64).
2. Log into the user interface (see Section 8.2, page 68).
3. Call up the menu
Device Parameters .
4. Select [ Edit parameters ].
5. Log in using the SMA Grid Guard code to change those parameters designated by a lock
(only for installers):
• Select the menu User Settings (see Section 8.3, page 69).
• In the subsequent context menu, select [ SMA Grid Guard login ].
• Enter the SMA Grid Guard code and select [ Login ].
6. Expand the parameter group that contains the parameter which is to be configured.
7. Change the desired parameters.
8. Select [
Save all ] to save the changes.
☑ The inverter parameters are set.
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. when the battery is switched off), 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.
