10.6 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.
Requirements:
☐ Changes to grid-relevant parameters must be approved by the responsible grid operator.
☐ If parameters that can only be changed after logging in as a service provider are set, the
setting of the parameter must be described in the documentation.
☐ You are logged in on the user interface (see Section 10.2, page 56).
Procedure:
1. Click on [Device monitoring] in the menu.
2. Select [Parameters].
3. Select the desired parameter group.
4. Change the required parameters.
5. Select [Save settings] to save the changes.
10.7 Configuring SMA ShadeFix
The basic procedure for changing operating parameters is explained in another section (see
Section 10.6, page 61).
Requirements:
☐ You are logged in on the user interface as Service provider (see Section 10.2.2, page 57).
Procedure:
• To set the time interval for SMA ShadeFix, set the parameter MPPSHdwTime in the
parameter group Extended Model 2-1 RW to the desired value. The ideal time interval is
usually 6 minutes. This value should only be increased if the shading situation changes
extremely slowly.
