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 PvHub2.0 app is installed on your device
Step-by-Step Instructions
1. Connect the inverter to the network
Connect an Ethernet cable to port G on the inverter
Verify the connection is established by checking the network status in the PvHub2.0 app
For network infrastructure requirements and troubleshooting, see Infrastructure requirements for the gateway.
2. Access the inverter settings
Open the PvHub2.0 app
Follow the instructions to complete the inverter setup in the App
3. Plug&Play discovery and configuration
This inverter supports Plug&Play, requiring no manual configuration. It is automatically detected during gateway commissioning and configured with the appropriate 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 a-TroniX AX Plus 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.
Country-specific configurations
Germany
Applies to PV installations exceeding 2 kWp installed after February 24, 2025.
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.
Energy management settings are configured automatically based on the inverter model. No manual changes are needed in the commissioning wizard.
Additional Information
Dual Meter Configuration
The AX Plus inverters support connecting two meters:
One for the grid connection point
A second for an additional PV system
Important
When using two meters, ensure they do not use the same communication address to prevent conflicts. Refer to the a-TroniX user manual for configuration instructions.
FAQ
Why isn't the inverter appearing in the commissioning wizard?
Check that you completed the inverter setup with no errors in the PvHub2.0 app. Verify all components (data logger, inverter, battery, energy meter) work correctly. Make sure the Ethernet cable is connected to the LAN port. Restart the gateway and wait for the network scan to complete.
How do I update the firmware of the inverter?
You can perform the update directly through the PvHub2.0 app.
For detailed update instructions, refer to the official a-TroniX documentation.
