Nucleo GX: communication-centre
The Nucleo GX is a compact, high-performance communication centre for monitoring and controlling your
Victron system. It offers fast system response, reliable connectivity, and flexible expansion via USB accessories.
Ideal for VE.Can-based installations such as RS systems, it provides full GX functionality with simple setup and
seamless remote access through VRM, LAN, or WiFi.
Additional functionality such as VE.Bus connectivity, relays, or analogue inputs can easily be added via
optional USB accessories: the MK3-USB interface, GX I/O Extender 150, or GX Tank 140.
Although the Nucleo GX has no HDMI port, an Android GX WiFi Display can be used for local display and
control. System access is also available through VictronConnect, a web browser, or VRM.
Compact and high-performance GX platform
Equipped with a quad-core processor, the Nucleo GX delivers fast and reliable system performance in a
compact design. It supports up to 25 connected devices via VE.Direct and USB, and even more via VE.Can,
ensuring smooth data handling and responsive control in any installation.
Remote Console on VRM
Monitor, control, and configure the Nucleo GX remotely, just as if you were standing in front of it, using
Remote Console on VRM. The same functionality is available locally via LAN or through the built-in WiFi Access
Point.
Perfect monitoring & control
Monitor real-time system information such as battery state of charge, power consumption, and power harvest
from PV, generator, or mains. Easily start or stop generators automatically, adjust key system settings, and
track performance trends. Stay informed with alerts, run diagnostics, and resolve issues remotely through VRM
or the local network.
Simple mounting and configuration
The Nucleo GX is easy to install on a wall or with the optional DIN35 DIN-rail adapter. Built-in Bluetooth
enables quick setup and configuration using the VictronConnect app.

Notes
1. For more detailed information about the Nucleo GX, please visit the Victron GX product range page.
2. Bluetooth functionality is intended to be used to assist with initial connection and networking configuration. You
cannot use Bluetooth to connect to other Victron products (e.g. SmartSolar charge controllers).
3. The listed maximum in above table is the total connected VE.Direct devices such as MPPT Solar Charge controllers.
Total means all directly connected devices plus the devices connected over USB. The limit is mostly bound by CPU
processing power. Note that there is also a limit to the other type of devices of which often multiple are connected: PV
Inverters. Up to three or four three phase inverters can typically be monitored on a CCGX. Higher power CPU devices
