If you've forgotten the password for your SMA Inverter, you can unlock it using a Personal Unlocking Key (PUK). Request a PUK using the application form available at www.SMA-Solar.com. Then, open the user interface, enter the PUK in the Password field, and select Login. Next, go to Device Parameters, click on [Edit parameters], and in User Rights > Access Control, change the password for the desired user group. Finally, select [Save all] to save the changes.
