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).
Tip: 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 4.1, page 19).
3. Enter the PUK instead of the password into the field Password.
4. Select Login.
5. Call up the menu Device Parameters.
6. Select [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.
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).
