Step By Step Guide: Connecting SMA Inverter to Wifi

🔧 Steps to Connect Your SMA Inverter to Wi-Fi:

1. Power On the Inverter

Ensure your SMA inverter is powered on and the display (if applicable) is active.

2. Activate the Inverter’s Wi-Fi

  • SMA inverters typically broadcast their own Wi-Fi network upon startup.

  • Look for a Wi-Fi network named something like:
    "SMA[SerialNumber]" or "SMA-WLAN..."

3. Connect to the SMA Wi-Fi

  • Use a smartphone, tablet, or laptop.

  • Go to your Wi-Fi settings and connect to the inverter's Wi-Fi network.

  • If prompted for a password, it’s usually printed on the side of the inverter or in the user manual (often labeled as “WLAN key”).

4. Access the Inverter Interface

  • Open a web browser and go to:
    http://192.168.12.3

  • This will open the inverter’s local interface.

5. Login

  • Use the default credentials unless changed:

    • User role: Installer or User

    • Password: Check the inverter label or documentation. For “Installer,” you may need a password from the installer or SMA.

6. Connect to Your Home Wi-Fi

  • Once logged in:

    • Go to Settings > Device Configuration > Network Settings

    • Select your home Wi-Fi network and enter the password

    • Save the settings

7. Confirm Online Status

  • The system should connect to the internet within a few minutes.

  • You can then monitor it via SMA Sunny Portal or SMA Energy App once online.
