Setting The Rated Residual Current Of The Residual-Current Device; Saving The Configuration In A File; Adopting A Configuration From A File - SMA STP3.0-3AV-40 Operating Manual

8 Operation
8.16 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.

8.17 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.

8.18 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 8.17 "Saving the Configuration in a File", page 66). When saving, only the device
parameters will be adopted, not any passwords.
Requirements:
☐ Changes to grid-relevant parameters must be approved by the responsible grid operator.
☐ The SMA Grid Guard code must be available (see "Application for SMA Grid Guard Code"
at www.SMA-Solar.com).
Procedure:
1. Open the user interface (see Section 8.1, page 49).
2. Log into the user interface as an Installer (see Section 8.2, page 53).
