12.1 Forgotten Password
If you have forgotten the password for the inverter, you can unlock the inverter with a Personal
Unlocking Key (PUK). For each inverter, there is one PUK for each user group (
User
and
Installer
).
Tipp: With PV systems that are registered in a communication product, you can also assign a new
password for the user group
Installer
via the communication product. The password for the user
group
Installer
is the same as the system password in the communication product.
Procedure:
1. Contact the Service and request a PUK (see Section 15 "Contact", page 92).
2. Open the user interface (see Section 9.1, page 43).
3. Enter the PUK instead of the password into the field
Password
.
4. Select
Login
.
5. Call up the menu
Device Parameters
.
6. Click on [
Edit parameters
].
7. In the parameter group
User Rights > Access Control
change the password of the desired
user group.
8. Select [
Save all
] to save the changes.
Password assignment for inverters that are registered in a communication
product
The password for the user group
Installer
is also the system password for the system in the
communication product. Changing the password of the user group
Installer
can lead to the
inverter no longer being able to be reached by the communication product.
• In the communication product, assign the changed password of the user group
Installer
as the new system password (see the manual of the communication product).
