12.1 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 9.1, page 46).
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).
