4.13 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.
No configuration via SunnyExplorer
SunnyExplorer does not support the configuration of inverters with 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 user interface for the configuration of the inverter.
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4.2, page22).
2. Log into the user interface (see Section4.3, page26).
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4.4, page28).
• 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. 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.
