Service Tip: Pay Attention When Assigning Password in Sunny Portal

From on July 1, 2014 in Category Service with 18 Comments
The pv system password in Sunny Portal

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:

“User”: 0000

“Installer”: 1111.

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.

Please do remember that the password for the "Installer" user group and the system password is one and the same password. In this way, you can access all devices in the plant through both, Sunny Explorer and Sunny Portal. All data are displayed.

Please do remember that the password for the “Installer” user group and the system password is one and the same password. In this way, you can access all devices in the plant through both, Sunny Explorer and Sunny Portal. All data are displayed.

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.


Reset Password

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.

      Hi Chris,
      If you have lost or forgotten your PV System password, you can set it new in Sunny Portal. This is possible in the following menu:
      >Configuration >Device Overview >Properties of Sunny Home Manager
      Kind regards, Annika

      Hello Wael,
      The PUK actually won´t replace any password. If you lose your password, it is necessary to reactivate the access with the help of a PUK (Personal Unblocking Key).
      Please visit our website to find out more. For further information about the activation of the inverters, please refer to the manual of the respective communication product.

      Kind regards, Jennifer

      Hi Barry,
      To register your Sunny Boy at Sunny Portal to get the full App support is pretty easy, please follow the attached link and enter the PIC and RID data from your device.
      Further we have a video on YouTube, for similar products where you can see the full instruction how to do the registration.
      In case there is any question left feel free to contact the SMA Service Line.

      Hi Willem,

      Usually, the default password is sma (for users and/or installers)
      If you are still not able to login using sma as the password, please contact the Service Line and let us know the serial number of your unit so we could work on a solution.
      It is also advisable to provide your contact details as well so the support is even faster – please write directly to

      Kind regards,

      Hello Rob,
      We have an application for the iPhone. You can download it from the Apple-Store.
      This application synchronizes with Sunny Portal.
      If you can see live values, depends which kind of data logging is used in your plant. Only plants with Webconnect or with a Sunny Home manager are sending live values.

      If you have further questions, please call our SMA Service Line in your country.

      Best regards
