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
.
8.17 Setting the Rated Residual Current of the Residual-
Current Device
When using residual-current devices with a rated residual current of 30 mA, set the rated residual
current to 30 mA. In this way the inverter reduces the operational leakage currents and prevents a
false triggering of the residual-current device (for further information, see technical information
"Leading Leakage Currents" at www.SMA-Solar.com).
The basic procedure for changing operating parameters is explained in another section (see
Section 8.10 "Changing Operating Parameters", page 61).
Procedure:
• Select the parameter
RCD adjustment
and set it to
30 mA
.
8.18 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 8.1, page 49).
2. Log into the user interface (see Section 8.2, page 53).
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.
