The Service Line has been receiving a lot of questions about passwords lately. Some customers want to know why they can no longer access the inverter in a PV system using their password. Why is this happening?
SMA uses various types of passwords. For details, see the technical description: System Monitoring—SMA Safety and Password Concept for Password-Protected PV Systems With Bluetooth® Wireless Technology.
The PV System Password
To prevent unauthorized access, SMA recommends choosing a separate password for each user group (“User” and “Installer”).
All devices with the same password for the “Installer” user group and the same NetID form a system. Therefore, SMA refers to any password that is the same for all the devices of a system as the pv system password.
The devices in the system come with the following default passwords:
Some customers refer to the password for the “Installer” user group as the “Installer password”.
That sounds simple enough. So what is causing the confusion?
To register a system with Speedwire/Webconnect or with a Sunny Home Manager in Sunny Portal, you must enter a pv system password. Important: This is the password for the “Installer” user group that was assigned on-site during start-up. Please enter this in the appropriate field (see screenshot above this article).
It gets more complicated if the default password was not changed during start-up. For security reasons, you cannot simply enter the standard password 1111 into Sunny Portal. What happens if you do? The new password overwrites the default password and applies it to all devices registered in the Sunny Portal system. Please keep this in mind, and be sure to write down the pv system password you set up in Sunny Portal.
If you later try to access your devices on-site (for example with Sunny Explorer) using the default password for the “Installer” user group, it will no longer work. Please use the password that you created as the pv system password in Sunny Portal.
By the way: The system password for the “User” user group is not affected because it cannot be changed in Sunny Portal.
Potential Problems During Data Transfer
Even if you understand and follow the procedure described above, complications can occasionally arise during data transfer. There are two possible situations:
- The new pv system password created in Sunny Portal has not been applied to the inverters. This can happen, for example, if the devices cannot be accessed or are not feeding during registration. If you notice that you cannot access the inverters with your current password, or no data appears in Sunny Portal, please try again with the “old” Installer password.
- Your installation company changed the default system password 1111 to a new password that you do not know. In this case, Sunny Portal cannot access your devices, and for security reasons a new system password cannot be set. The system is still registered in Sunny Portal, but no detailed system data is shown. If this happens, please contact your installer.
If you forget your password, you will need a Personal Unblocking Key (PUK). You can request one from our Service Line using this form. Learn more about it in our upcoming service tip.
