There are many benefits for connecting your Sunny Boy inverter to the internet, such as real-time monitoring, remote fault diagnosis, easy access to SMA online platforms, among many others. New generation Sunny Boy inverters now come equipped with built-in WiFi and an Ethernet port for monitoring.

 

Preparation Checklist 
  • Bring your smartphone, tablet or laptop with Ethernet patch cable along to the site preperation

If the installation site is remote, it is your first time commissioning this type of inverter, or it is known the inverter’s WiFi has been deactivated, it is recommended you bring a computer with an Ethernet port and an Ethernet patch cable. This will make the configuration process easier should you experience any difficulty. Otherwise, any smartphone or tablet with WiFi capability should be sufficient.

  • Take a picture of the serial number, PIC and RIDserial number

Information such as the serial number, PIC and RID can be found on the inverter label and the documentation that comes with the inverter. After the device is installed, information on the label may become difficult to read. If this information is not on hand (after leaving the installation site), taking a picture of the label and having it readily available will be useful for future reference. This information is necessary for registration to Sunny Portal and may be needed during commissioning.

 

Step 1 – connect to the inverter

There are two different ways to connect your Sunny Boy inverter with WiFi to a local wireless network:

a ) Connecting via WiFi using your laptop/smartphone/table
b ) Connecting via an Ethernet cable using your laptop

 

a ) Connecting via WiFi using your laptop/smartphone/tablet

Access your device’s WiFi connection in order to detect and connect to the Sunny Boy inverter which will be in the format of SMA19xxxxxxxx.

 

settings

 

For a brand new installation, the WiFi password (Network Security Key) is SMA12345 (mind the capital letters).

After the initial inverter setup through the ‘Installation Assistant’, this initial WiFi password will permanently change to the WPA2-PSK password written on the inverter label. Be mindful of the password as it is case sensitive. The initial WiFi password will also change to the WPA2-PSK password after 10 hours of operation whether or not the initial setup has been performed.

b ) Connecting via an Ethernet cable using your laptop

Connect the Ethernet cable to the computer and to the inverter port as shown in red in the image below.

Step 2 – Log in to the inverter interface

Once you have connected to the inverter via WiFi or with a cable, go to your internet browser and type in the default IP address into the adress bar according to the image below.

This will log you into the Sunny Boy’s web user interface. To perform the initial configuration, you must login as ‘Installer’ by changing the User Group dropdown.

The first time you login, it will ask you to create a password, so make sure you keep the password in your records. The password will be used to register the inverter in Sunny Portal.

Step 3 – network configuration to a local wireless router

Once logged in, you will have the option to setup the inverter using the ‘Installation Assistant’.

If the “Configuration with Installation Assistant” does not appear, it can be selected from the symbol in the top right-hand corner of the interface shown below.

To synchronize the inverter to your local wireless network, select the “WLAN” tab and search for the local wireless network the inverter is connected to. Select that wireless network’s “Settings” icon.

If the wireless network has a password, enter it in the area shown and then click “Connect to WLAN”

wlan-settings

 

 

The router will then assign an IP address to the inverter if DHCP is enabled in the router. The new IP address will be shown in the network configuration page.

 

Note the new IP address of the inverter as this is how the customer will be able to login in the future.

Click “Save and Next”. The Sunny Boy inverter has now been connected to the local wireless network. To complete commissioning, continue with the prompts in the Installation Assistant.  The following video gives you an overview of these commissioning steps which are completed by an installer: Configuration of the Sunny Boy 1.5/2.5 via Web UI 

 

Conclusion

New generation Sunny Boy inverters come equipped with factory-integrated WiFi and Ethernet capability which makes it very easy to integrate into a home network. This makes it ideal for local monitoring via the inverter’s own wireless home network or for online monitoring with SMA’s platforms such as Sunny Portal and Sunny Places. Connecting to the local wireless network is an easy process which can be completed in three simple steps: connecting to the inverter, logging in to the inverter’s user interface and configuring the network to a local wireless router.

      Hello Guillermo,
      If you don`t have any WiFi- Password there optionally inverter WPS-Function can be used.
      Can be activated double-knocking at inverters chassis =>blue led starts blinking fast for 2min
      Time enough to press WPS- Button on your device (smart phone, tablet), and pairing “device < ->inverter” is taking place automatically.
      Optionally, please plugin an Ethernet-cable in order to entering inverters WEB-UI by putting it`s IP-Adress into a browser.
      It`s WEB-Interface is opened and there, just under “Device Parameter”, you can change inverters WPA-2-Key as well.
      We hope it helps you.
      Kind regards, Carolin

    Dear SMA,

    This blog is helpful, monitoring of the new generation sunny boy is working fine. But every other day I get a lot of errors like DNS-server not configured, Default gateway not configured. Webconnect error – nog connection. Sometimes the data on the sunny portal and mobile APP are not showing up for the whole day. I tried to open some ports on the router in the clients house but this didn’t help yet.

    Please any advice.

    Regards,

      Hello Andrew,

      the STP20000TLEE-10 has no optional SPD Type II surge protectors, only SPD III. Please have a look in this document, there you will find all information concerning this topic.

      Warm Regards

    Hi, What do you do if you are doing an off grid install in a remote area with cellular access but no wifi? Any way you can get remote monitoring using GPRS or something similar? Thank you.

    I would recommend posting a video of these steps with a person actually doing them. Videos are a lot easier to follow. Thanks!

      Hello André,

      If the blue LED is off, please check if the inverter has an active network connection and also access to the internet.
      Log in to your router to check if an IP address has been assigned properly. If the inverter has not an active network connection, please restart the procedure
      “Integrating the inverter into the network”, which is described well in the current operating manual of your inverter.

      Regards, Lucas

    Does Sunny Tripower has built in WIFI feature as well? If yes, am I going to follow the steps above? Thanks.

      Hello Philip,

      First, please restart all network units starting with the router. Once this is done, please check if the issue persists.
      Please check in the router if an ip-address has been assigned to the inverter.

      If the inverter is still having troubles connecting to network, please feel free to contact your Service Line. The colleagues will be glad to assist further.

      Kind regards,
      Lucas

    The WPA2-PSK password isn’t written on the inverter label. Can I choose my own WPA2-PSK password during the initial inverter setup through the ‘Installation Assistant’?
