Forgotten Password
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 PV 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).
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 per 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:
- Log into the SMA Online Service Center.
- Select the Help & Knowledge menu.
- Click on PUK (Personal Unblocking Key) in the drop-down menu.
- Select the PUK level User or Installer.
- Enter your serial number.
- Click on Submit PUK request.
