8.11 Changing the Password
The password for the inverter can be changed for both user groups. Furthermore, the user group
Installer can change the password for the user group User as well as its own password.
PV systems registered in a communication product
With PV systems that are registered in a communication product (e.g. SunnyPortal,
ClusterController), you can also assign a new password for the user group Installer via the
communication product. The password for the user group Installer is also the system
password. If you assign a password for the user group Installer via the user interface of the
inverter that does not correspond to the system password in the communication product, the
inverter can no longer be reached by the communication product.
• Ensure that the password for the user group Installer is the same as the system password
in the communication product.
Procedure:
1. Activate the user interface (see Section8.2, page56).
2. Log into the user interface (see Section8.3, page60).
3. Call up the menu Device Parameters.
4. Select [Edit parameters].
5. In the parameter group User Rights > Access Control change the password of the desired
user group.
6. Select [Save all] to save the changes.
8.12 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.
Requirements:
☐ Changes to grid-relevant parameters must be approved by the responsible grid operator.
Procedure:
1. Open the user interface (see Section8.2, page56).
2. Log into the user interface (see Section8.3, page60).
3. Call up the menu Device Parameters.
4. Click on [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8.4, page62).
• In the subsequent context menu, select [SMA GridGuard login].
