The Nucleo GX is a compact communication centre that brings Ekrano GX-class performance to systems that don't need a full set of connections. Fast, responsive and cost-optimised, it is the most focused member of the GX family.




Extremely powerful processor
VRM remote management
Lower cost GX device
Works with VictronConnect
Simple mounting
Integrates with MFDs & NMEA 2000


Nucleo GX
Monitoring & control
Always know the system is doing what it should. The Nucleo GX works with the free VictronConnect app and Victron Remote Management (VRM) portal, regarded as the standard in monitoring software. Get full insights and control from any device, and use a tablet or mobile as a local display.

Works with
Compatibility
Connect up to 25 devices using the VE.Direct, VE.Can, and USB ports, with room to add more via a GX I/O Extender 150. Plug in an RS or HS series inverter/charger directly, or a MultiPlus, Quattro, or other device via a dongle. The Nucleo GX will handle it all without fuss.

Managed lithium batteries
Using the same powerful quad-core processor as the Ekrano GX, the Nucleo GX manages all connected Victron products and a wide range of third-party devices with ease.
The Nucleo GX runs on Venus OS, Victron's own tried and tested operating system. Regular updates keep adding new features and improvements, so performance stays on par long after installation.
To get the most out of an energy storage or off-grid system, the Nucleo GX supports both Victron batteries and all major third-party brands. Full visibility and control, without any vendor lock-in.
Because of its compact enclosure the Nucleo GX is an easy fit in any setup. Mount it on a wall or DIN-rail, connect the other devices, and it’s ready to go.
Need more connectivity? Use the Nucleo GX's USB ports to add VE.Direct and VE.Bus capabilities via a simple dongle, or expand its I/O ports with the Victron GX IO-Extender. All without replacing the device.
No need to be near the system every time something has to be adjusted. Settings and firmware updates can be managed remotely via VRM or locally over WiFi, just as with any GX device. Less time on the road, more time getting things done.
Check how a system is running from any computer, tablet, phone, or smartwatch. Monitor performance or configure settings as needed, and let Victron's software handle the rest in the background.





VRM portal
The dashboard
Full control
Stay ahead of issues
Tablet & mobile as a local display
The VRM portal provides a complete, real-time overview of system performance: battery status, PV, generator, mains input and more. Instantly see the parameters that matter most, create alerts for anything that needs attention, and manage multiple systems from a single account. Available in any browser, the VictronConnect app, the Victron watch app, and app widgets.
Check battery levels, solar harvest, grid input, and overall consumption in real time. Add other useful readouts from devices connected via a dongle. Venus OS shows all the important energy flows in one clear overview.
More than just a monitoring device, the Nucleo GX offers full system control. Adjust input and charge current limits, control connected devices, and change system settings, all from the same interface.
Set up alerts and alarms for anything that needs attention. The Nucleo GX helps to catch issues early, so the system stays safe. With a GPS module connected, VRM can also be used to configure geofence alerts for location-based monitoring.
Open the Venus OS web interface on a tablet or smartphone and get a full system rundown, just like on a dedicated display. With portrait view now supported, the same clear dashboard works on any familiar screen.
The Nucleo GX doesn’t just offer full system monitoring and control. It also combines data from all connected devices to keep things running efficiently. Distributed Voltage and Current Control (DVCC) is one example, balancing charging and discharging across the entire setup.





Connect to anything
Works with other brands
Energy automations
MFD integration
Whatever platform, service, or device a system needs to talk to, one of the built-in protocols will handle it. Node-RED and Shelly cover automation and smart home integration, REST API and MQTT handle web dashboards and real-time data, and Modbus TCP connects to industrial and building management systems. All supported straight out of the box.
For the Nucleo GX, a system doesn’t have to be all Victron. It’s specifically designed to accept a wide range of products from other brands, including managed lithium batteries, EV chargers, heat pumps (via SmartGrid), and CAN Bus devices. Advanced generator management is covered too, with support for DSE, DEIF, CRE and ComAp controllers.
The Nucleo GX helps a system do more than follow a fixed schedule. Build intelligent automation flows that respond to real-time data, from charging logic and load management to appliance control. Node-RED, the popular browser-based low-code editor, provides the tools to set up and adapt these flows as needs change.
Running a marine system? Connect the Nucleo GX to a Multi-Function Display and bring all important energy readouts right to the helm. NMEA2000 support means it works with leading MFD brands and the equipment already on board.

Complete system control, on-grid, off-grid, or at sea.
To have all key energy readouts right at the helm, the Nucleo GX can be connected directly to a Multi-Function Display. Plug in a GPS module and VRM adds geofence alerts, providing an extra layer of security.
A clean fit for energy storage systems, the Nucleo GX supports features such as peak shaving, dynamic ESS, and backup power. It works directly with Multi RS and HS inverter/chargers and balances charging and discharging across the whole setup.
Keep any off-grid system running the way it should. The Nucleo GX makes it easy to stay on top of energy flows, from solar harvest to battery levels. Remote access via VRM keeps everything in view and under control.
