You absolutely can connect various PV Inverters to the Cerbo GX.
If you have a Fronius, SMA, SolarEdge, or ABB inverter, they can be connected through a LAN connection.
Just follow the instructions specific to your inverter brand.
If your inverter can’t be interfaced digitally, no worries! You can use a meter like an AC Current Sensor or an Energy Meter, wired or wireless, to make the connection.
Remember, these connections are for monitoring your system’s performance but don’t directly affect it.

Not sure which PV inverter you have but here is a short guide on setting Up Fronius PV Inverters with Victron Cerbo GX:
1. Preparation:
-
Check Compatibility: Ensure your Fronius inverter model (e.g., Primo, Symo, Eco) is compatible with the Victron GX device.
-
Update Firmware: Update both Fronius and Victron devices to the latest firmware.
2. Configuration of Fronius Inverter:
-
Micro-Grid Setup: Set the Fronius inverter to ‘Setup MG’ mode for Micro-Grid systems. This aligns with Victron’s frequency shift settings.
-
Inverter Specifics: For European AC grids, use compatible ROW inverters like Fronius Primo or Symo. For US-type AC grids, ensure you have the appropriate UL inverters.
3. Configuring Victron Cerbo GX:
-
Assistant Selection: Load the Multi or Quattro with the PV Inverter support Assistant for off-grid systems or the ESS Assistant for on-grid/energy storage systems.
-
VE.Configure Software: Use this software to configure the system with the latest version. Add the necessary Assistants to regulate output frequency.
-
Setting Frequencies: Adjust settings for different frequencies (50Hz and 60Hz) based on your system’s requirements.
4. LAN Configuration for Communication:
-
IP Configuration: Set a valid LAN IP address on the Fronius using DHCP, Link-local, or manual addressing methods. Ensure the GX device and Fronius are on the same subnet.
-
Connecting Devices: Connect both devices to the same LAN via Wi-Fi or Ethernet. Confirm IP settings are correctly configured.
5. Adding Fronius to GX Device:
-
Scan for Inverters: Use the ‘Scan’ function in the GX Device menu to detect the Fronius inverter.
-
Configure Inverter Details: Set the position relative to the Multi or Quattro and phase for each inverter. Configure automatic scanning settings based on your network setup.
6. Monitoring and Control:
-
GX Device Monitoring: Once configured, the Fronius inverter’s details, such as current state and power generated, will be visible on the GX device.
-
VRM Portal: Use the VRM Portal for detailed yield monitoring. Ensure to enable the PV Inverter yield widget(s) in the settings.
7. Zero Feed-in Configuration:
-
Venus Control: The Venus device controls the Fronius output power for Zero feed-in systems. Configure this through the ESS manual.
8. Troubleshooting and FAQs:
-
Flickering Issues: If experiencing flickering, Fronius has special firmware to address this. Contact Fronius Tech Support for assistance.
-
Microgrid Setup: For specific setups like those with Neutral conductor, refer to the detailed Fronius manuals and support.
By following these detailed steps, you should be able to set up and configure your Fronius PV Inverter with a Victron Cerbo GX system effectively, ensuring optimal performance and monitoring capabilities. Always refer to the latest manuals and technical support for the most accurate and specific guidance tailored to your system.
