Procedure:
• To use the Modbus interface, enable the Modbus interface and adjust the communication
ports if necessary (see the technical information "SMA and SunSpec Modbus® Interface" at
www.SMA-Solar.com).
9.12 Setting SMA ShadeFix
You can set the time interval in which the inverter has to determine the optimum operating point. If
you do not want to use SMA ShadeFix, you can disable the feature.
The basic procedure for changing operating parameters is explained in another section (see
Section 9.10 "Changing Operating Parameters", page 54).
Procedure:
• In the parameter group
DC-side > DC settings > SMA ShadeFix
, set the parameter
Time
interval of SMA ShadeFix
and set the required time interval. The ideal time interval is
usually six minutes. This value should only be increased if the shading situation changes
extremely slowly.
☑ The inverter optimizes the MPP of the PV system at the predetermined time interval.
• In order to disable the SMA ShadeFix feature, in the parameter group
DC-side > DC settings
> SMA ShadeFix
, set the parameter
SMA ShadeFix switched on
to
Off
.
9.13 Saving the Configuration in a File
You can save the current configuration of the inverter in a file. You can use this file as a data
backup for this inverter and then import this file into this inverter again or another inverter from the
same type or device family to configure the inverter. When saving, only the device parameters will
be saved, not any passwords.
Procedure:
1. Activate the user interface (see Section 9.1, page 43).
2. Log into the user interface (see Section 9.2, page 46).
3. Select the menu
Device Configuration
.
4. Select [
Settings
].
5. In the context menu, select [
Saving the configuration in a file
].
6. Follow the instructions in the dialog.
9.14 Adopting a Configuration from a File
To configure the inverter, you can adopt the configuration from a file. To be able to do this, you
must first save the configuration of another inverter from the same type or device family in a file (see
Section 9.13 "Saving the Configuration in a File", page 56). When saving, only the device
parameters will be adopted, not any passwords.
