Switching the Dynamic Power Display Off

As standard, the inverter signals its power dynamically via the pulsing of the green LED. When
doing so, the LED flashes on and off uniformly or is permanently lit at full power. The various
gradations are related here to the set active power limit of the inverter. If this display is not desired,
switch this function off in accordance with the following procedure. Once this has been done, the
green LED is lit permanently to signalize feed-in operation.
The basic procedure for changing operating parameters is explained in another section (see
Section 4.11 "Changing Operating Parameters", page 31).
Procedure:
• In the parameter group Device > Operation, select the parameter Dynamic power
display via green LED and set this to Off.

4.10 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.
