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, Sunny Home Manager), 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 8.1, page 110).
2. Log into the user interface (see Section 8.2, page 112).
3. Call up the menu Device Parameters.
4. Select [Edit parameters].
