8.1 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).
Useful hint: With PV systems in SunnyPortal, you can also assign a new password via SunnyPortal
for the user group Installer. The password for the user group Installer is the same as the system
password in SunnyPortal.
Procedure:
1. Request PUK (application form available at www.SMA-Solar.com).
2. Activate the user interface (see Section5.1, page20).
3. Enter the PUK instead of the password into the field Password.
4. Call up the menu Device Parameters.
5. Select [Edit parameters].
6. In the parameter group User Rights > Access Control change the password of the desired
user group.
7. Select [Save all] to save the changes.
PV Systems in SunnyPortal
The password for the user group Installer is also the system password for the PV system in
SunnyPortal. Changing the password of the user group Installer can lead to the inverter no
longer being able to be reached by SunnyPortal.
• Assign the changed password of the user group Installer as the new system password in
SunnyPortal (see the SunnyPortal user manual at www.SMA-Solar.com).
