Before you start

Before you begin, make sure:

The inverter is physically installed and powered on
The inverter is updated to the latest software version
The SMA 360° app is installed on your device
You are logged in to the SMA 360° app with your SMA ID

Step-by-Step Instructions

1. Connect the inverter to the network

Connect an Ethernet cable to port D on the inverter
Verify the connection is established by checking the blue LED on the inverter or in the SMA 360° app

For network infrastructure requirements and troubleshooting, see Infrastructure requirements for the gateway.

2. Access the inverter settings

Open the SMA 360° app
Select the inverter in the app and scan the QR code of the inverter
Access the settings with the password that has been created during the initial setup

3. Enable communication via Modbus

Navigate to
Device configuration → Type of communication
Configure the following Modbus settings:
- Modbus active: Yes
- Port: 502
- Unit ID: 3
- Modbus SunSpec profile version: Standard
Save the settings

4. Discover the inverter in the commissioning wizard

The inverter is now ready for the commissioning wizard. The gateway will scan the network to find available devices, which may take a few minutes. Once complete, the SMA Sunny Tripower Smart Energy inverter will appear on the results page.

When the inverter is detected, in most cases set the asset type to Hybrid (PV and Battery) from the dropdown.

If you are using the inverter exclusively as a PV inverter, select PV System. If it is used solely as a battery inverter, choose Battery.

For detailed information refer to §9 EEG (2025) – 60% feed-in limitation

No additional inverter configuration is required. The inverter controls the grid feed-in limit directly (GCP Limit), supporting energy management optimization.

Set the following Energy management setting in the commissioning wizard:

Allow optimisation: Yes
Grid feed-in limit controlled by inverter: Yes

FAQ

Why isn't the inverter appearing in the commissioning wizard?

Check that the inverter is connected via Ethernet at port D and that Modbus is enabled (Port 502, Unit ID 3). Restart the gateway and wait for the network scan to complete.

How do I update the firmware of the inverter?

Download the latest firmware from the SMA website and perform the update through the SMA 360° app.
For detailed update instructions, refer to the official SMA documentation.

What are the login credentials for the inverter settings?

The installer password is set during initial commissioning of the inverter. There is no factory default — you created the password the first time you accessed the inverter settings.
