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. Request PUK (application form available at www.SMA-Solar.com).
  2. Open the user interface Establishing a connection to the user interface).
  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.

  1. 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).
