5.5 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. SunnyPortal,
ClusterController), 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.
