Service Tip: SMA PUK – How to Regain Access to Your System Data

SMA Service tip PUK

As promised in our previous post, we will be covering the SMA PUK (Personal Unlocking Key) in today’s service tip. We explain how your devices can be unlocked to restore normal access to your system data.

 

Before we get started, take a moment to make sure that you have really lost your password

Before anything else, you should check to make sure that you really can’t find the password for accessing your systems in the Sunny Portal. In a previous article called “Service Tip: Pay Attention When Assigning Passwords in the Sunny Portal,” we mentioned a number of circumstances that could result in your password being changed or overwritten.

If you’re sure you have lost your password, use this form to request a PUK from our Service Line. The PUK code does not come with your inverter.

 

How it works

Once your request has been received and processed by our staff, you will be able to unlock your inverter and set a new password via Sunny Explorer.

 

Exception: PV systems with Webconnect

In this case, contact our Service Line staff by phone to avoid permanent data loss.

 

Entering your PUK in Sunny Explorer

1. Open Sunny Explorer.

2. In the “User group” field, select the “Installer” user group.

3. Enter your PUK into the “System password” field.

4. Select [Next].
☑ Sunny Explorer displays the inverters in the plant tree without padlock icon.

5. Change the inverter password:
– Select the inverter in the system tree.
– Select the “Settings” tab.
– Select the parameter group “User Rights > Access Control”.
– Select [Edit].
– Assign the password you want to the relevant user group.

6. To unlock additional inverters with a PUK:
– Select Options > “Change user group.”

7. Unlocking additional devices one after another with a PUK:
You will need to wait about five minutes between each device, since the passwords need to be sent to the system first.
After waiting five minutes, simply repeat the steps in step 5 in order to unlock the next device.

8. Final step: Set a general system password. This system password will be set as the installer password on all the individual devices and will guarantee access to the entire system so that all modules can be accessed at the same time.

We hope this post will make it easier for you to complete the steps required in order to unlock devices with your PUK. If you have any additional questions, please feel free to add a comment or contact our Service Line staff.

    I am just off the phone to one of your technical team who advised me to request PUK codes as we cannot access data for one of the inverters on Sunny Portal and it looks like a password issue. He suggested we would require a code for each of the inverters.

    Site Address Park Farm

    Serial Numbers

    STP 20000 TL 30 1900719065
    STP 25000 TL 30 1900718317

    Can you please assist

    Regards

    Don’t buy this product, no way, I bought sunny boy 1,5/2,5 and configured by Veissmann company, do you know what! I’m just user and I can’t change any configuration as user but I see what how much I got and saved money, and do you know what! The data what I am getting it monthly is not correct 100% and if you want to change your Wifi password the system will not read it so the SMA Solar company not give the authorities to configure your inverter as Installer but user because you didn’t got course and training in them branches so you have inverter but you guest in it as user and they control it by them branches and if you want to change the password for configuration as you forgot it, hhhhaaaaa they will ask for PUK number and for sure they have it 😀 and you will pay € 15 Basic + € 3.50 per device, and do you know what! They will send you PUK number as user 😂 guys think twice before you will stuck like me what will save it by solar panels will give it for service👎🏻
