Service Tip: Pay Attention When Assigning 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”.

 

Problem-Solving

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.

    Hello,
    I am an owner (not an installer) of a Sunny Boy 3.0. A service person was at our site recently to fix a problem with the grid connection. He updated the firmware while he was at it. Sounded like a good idea to me… Only later I discovered that the connection to sunny portal had broken down around the same time.
    The installer company is now telling me that it surely is a problem with my router though I’ve told them several times that both the router UI and the sunny boy UI don’t show evidence of any connection problems. The inverter gets assigned an IP just like before.

    It’s sunny portal that cannot connect to the inverter anymore and is logging the infamous “Communication to the device failed. Incorrect user password. Data will be imported as soon as the device is available. Error code 721” error.

    Of course the installer is offering to send another service person to fix the issue – at my cost. But to me it’s obvious that the password problem was caused by the person that was here recently. The messages started in the log exactly at the time the firmware update was made. A fact that I pointed out to the installer company and that they so far have chosen to ignore.

    What can I as an owner do now if my installer is not willing to take this problem up with SMA?

    Brand new inverter, just recently installed. Upon first login to the Inverter, I was ‘forced’ to update the password and required to use a special character as well. I cut & pasted, into my Google Docs notes, the password set. I confirmed the password worked by re-logging into the inverter’s web based control panel. The following day, the password ‘magically’ changes on it’s own?!? It is overtly apparent to me, that this is not a ‘bug’ with the inverter’s. Combined with the fact that this ‘problem’ seems to afflict so many SMA inverters AND SMA ‘requiring’ a FEE be paid for the support service of RESETTING the password, quite clearly and overtly suggests that this password changed problem is manufacturer created intentional sabotage designed to extort additional funds from customers. At least in the United States, this is illegal, and should be reported to authorities and the FTC.

    SMA, you can provide me the ‘new’ password, if you so choose. Logically, since you changed it, that would infer that you know what the new password is, since you’re responsible for changing it. I will NOT be paying any funds in order to ‘reset’ the password, and emphasize that what you are doing is ILLEGAL and CRIMINAL.

    I will instead look into SUING SMA and reporting this scam, crime & extortion to our government authorities. If you would like to email me a working password, please feel free to, and though I highly doubt you require the serial number to provide the new password in which YOU created; however, humoring you, my serial number is.

      Hello Chris,
      First of all, we would like to emphasize that our netiquette must be observed when commenting. Comments should be made in a factual and friendly manner and should not be used to spread accusations or insinuations.

      Please contact SMA Service for further assistance. Alternatively, you can also contact your installer who set up the system and may have assigned a different password in the process. Further information on the PUK procedure can be found here. Since you are using a new inverter, the PUK 2.0 procedure may already be in use.

      For data protection reasons, we have removed your serial number before activating the comment.

    Seems this “Communication to the device failed. Incorrect user password. Data will be imported as soon as the device is available. Error code 721” occurs often. Can you pls enumerate possible causes or at least most common cause? We are currently experiencing on two installation sites. We did update “Installer password” on the inverter as per the new requirement (special character ! $ % & / ( ) = ? + − . ; : _ #) . Strangely, we did renew Sunny Portal (System Password) months ago and expected that all inverters on all of our installation sites will also update and some site did, except the two mentioned with the Error Code 721. Thanks

      Got the same problem after firmware upgrade. After contacting with Online Service Center they requested me to use the previous password, as sunnyportal’s password must be the same as installer password in the device. The only way for me was to use sunny explorer to revert to old installer password. It is impossible to do so from the web interface due to the new requirement.

      BTW, they told me that the new firmware does not request a password change …

    We also had to change our password on the SNA portal. From that moment no more power produced data from the Sunny Boy device were imported. So after reading the manual several times we concluded that the Installer password of Sunny Boy should also be changed (why not warn for that on the SNA portal????). But that didn’t help. The portal still does not show any actual data. The inverter operates normally (geen check mark when logging in on Summy Boy itself) and blue and green lights on the inverter but the event log on the device shows 10344, 10285, 10286, 10110 and 10343 messages and the event log on the SNA portal is empty. Our solar provider wants to charge a lot of money to “solve” this problem. What is happening in the SNA portal?

    hi, the password for our Sunny Webbox is no longer working (used to be the default sma) “password is not recognized”. We tried the reset button for < 5 seconds but that hasn't changed anything. No one seems to know the password or has changed it – how do we get this reset?

    Hi

    II need some help with the password . I can complete the form but you say that you need a signature; is it OK to print the form, sign it and then scan it and email it to you? Regarding payment, can that be done electronically e.g. by PayPal? Does the PUK get emailed back to me?

    I have upgraded to windows 11 and was not prepared for a password when logging into the Sunny Boy using Sunny Explorer. It was not clear what form the password should take i.e. is it all numeric, is it alphanumeric or a mixture of the two. I have seen a previous post for Sunny Portal that indicates the need for special characters e.g. ? or _ or – or !

    The SMA software I am using is 2.01.21, is this current, and I see that this is 32 bit software.

    On Sunny Explorer the fields are User Group with options User or Installer and a Plant Password.
    How do you use the PUK? When using the PUK do you select installer and paste the PUK into the plant password field? does that then force you to choose your own password, that being the installer password. how do you go about setting the user password?

    Your document on service tips [relating to Sunny Portal] has a paragraph:
    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 technical description link is 404

    Is there an up-to-date document stating how the PUK is used and how the user password is set?
    Many thanks

    I need some clarification. I upgraded to Windows 11 and was forced into a password reset. I wasn’t expecting this and now I can’t access my Sunny Boy. Previously 0000 and 1111 worked and now I need a password.
    I can go through the PUK process, but you need a signature. If I print the form, sign it then scan it and mail it to you, is that acceptable?
    How is the payment made – can that be done online e.g. PayPal.
    So that I am prepared [which I wasn’t when faced with a password change on first encounter] what format must the password take e.g. number of characters, a mix of alphabetical and numeric or numeric only and any special characters e,g, @ or & or # and are the alphabetic case sensitive?

    Your website http://www.SMA.de seems to be a general SMA website. It’s not clear whereabouts on this website I will find specific details on passwords and password reset.

    The options are against User group Options user or installer
    and plant password

    To use the PUK do you select installer and then paste the PUK into the plant password field. What happens then, are you asked for your own password [didn’t appear to have a secondary confirmation of the password when I was confronted] and is this password both the installer password and the user password or just the installer password, and a secondary password for the user has to be set and if so how is that done?

    Sorry to be so detailed but I was caught out the first time, and I don’t want to get caught again.

    Many thanks

    Got it working, I hope. But the way this works is very confusing altogether and not clear *at all*.

    I have a PV-installation dated 2013 (when the codes 0000/1111 were common)

    Recently I updated the (local/Win10) software Sunny Explorer to its latest version (2.01.21)
    On login, Sunny Explorer demands the user to change the (installer/user) passwords.
    Which is fine.
    It states the password-algoritm : at least 8 chars, at least 1 small letter, capital, at least one number

    ** However ** , the password-algoritm in the (remote/cloud) Sunny Portal is different. Here you expect us to enter: 8 chars minimum, a max of 12 chars, and *suddenly* a special character too.

    This led to the situation that the portal cannot read the data from the PV-installation and even more confusing log-messages like “Communication to the device failed. Incorrect user password. Data will be imported as soon as the device is available. Error code 721”.

    The field-description like “PV System Password” is confusing. I suppose this is the installer-password, as that one works?
    Upon synchronising the password locally with portal, it *seems* to be working again.

    All in all, not very user-friendly at all, this situation where algoritms/password-schema differ and descriptions are not the same.

    Hello, In 2013 I’ve had a Sunny Boy 3000TL-21 installed with 12 panels. For a long time I used the SpeedWire ethernet interface with the standard password (‘0000’ and ‘1111’). After an upgrade of Sunny Explorer it had me change the user password into a more complex password. Which I did and I can access the inverter with the new password. But now I want to log on as Engineer and when I use the ‘1111’ password it reports that it has to be changed and shows the SB3000TL-21 is locked. But as far as I know I’ve not changed the Engineer password. How can I get access as Engineer? I would like to enable port TCP 502 for reading system information with Home Assistant, will that work?

Recently the installer came out again as we were showing a grid fault error and Western Power had said for them to check to see if they could fix it – since then we can no longer access our system via wi-fi. I have tried everything I did the first time to connect it but it is saying incorrect password but this has not changed, I have even tried the setup SMA password but that didn’t work.

    I have two SB 5.0 inverters. They are both connected to my wifi with static IP addresses and show 100% connectivity. They both show that Webconnect has a good connection. Originally they both showed up in my sunny portal but after about a week only one device shows up. The other inverter gives an error 721 for an invalid password. Both inverters were set up with the same password and I am able to log into both inverters without any problem. I have called the service line a few times and they are unable to get the second inverter to show up in sunny portal either. The service line tech said that they get communication problems all the time and they are not sure what the problem is.

The webconnect was connected to the router and in the evening that day I registered it on sunnyportal. When prompted for plant password I entered the password I would like to use and now it does not want to connect to the inverter because of wrong inverter passsword (Error code 721). Since nobody changed inverter password during commisioning, what is default inverter password?

      Dear Hrvoje,

      Usually, the default password for the group “installer” is 1111. For the group “user”, please enter 0000 as password.

      Please do not hesitate to contact directly our Service Line if you have further questions.

      Kind regards,
      Rhea

      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

    Hi,
    i have a question for you, Dose PUK replace installer password or just user password.
    since some time i need as installer to block access to the parameters area and plant engineers try to access that area.
    Thanks

      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 http://www.SMA.de 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

    My installer installed my Sunnyboy 1.5 and assigned a password (which I have) and its connected to the home internet. Unfortunately he didnt register the system on Sunny Portal in time and so I cant use the app. How to I get it registered, is this also done through PUK reset?

      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 Serviceline@sma.de

      Kind regards,
      Julia

      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. http://www.sma.de/en

      Best regards
      Leonie
