Restoring the password without product key

If you have forgotten the product's password and the product key has been lost, you can create a new password and a new product key by carrying out the following steps.

Password assignment for inverters that are registered in a System Manager (e.g. SMA Data Manager)

The password for the user group Installer is also the system password for the PV system in the System Manager or Sunny Portal. Changing the password of the user group Installer can lead to the inverter no longer being able to be reached by the System Manager.

  1. In the System Manager, assign the changed password of the user group Installer as the new system password (see the manual of the System Manager).

Requirements:

  • The login page of the user interface must be open.

Procedure:

  1. Select the group User or Installer.
  2. Click on [Forgot your password?].
  3. Click on [Product key lost?] wählen. If you have not yet generated a product key, the name of the specific device secret is displayed instead of Product key. In this case, click on [### lost?].
  4. Read the help text and enter a new password.
  5. Click on [Next].
  6. Perform one of the displayed actions within the specified time period.
  7. A newly generated product key is displayed.
  8. If the action performed was tapping the enclosure lid 2 times, the blue LED will flash rapidly.
  9. Write down the new product key immediately and keep it safe. After leaving this page, the newly generated product key can no longer be displayed. The previously valid product key is invalid after a new product key is generated. The copy of the product key must be accessible only to you.
  10. Select [Login].
  11. You are logged in on the user interface of the product.
