Victron Nucleo GX

Victron Energy Nucleo GX is a compact communication centre for centralised monitoring and control of Victron energy systems. Running Venus OS, it combines data from connected inverter/chargers, solar charge controllers, batteries and other devices, providing fast access to system status and key energy flows.

Nucleo GX is designed for installations that do not require all the built-in interfaces of larger GX devices. It provides remote access through the VRM Portal, local access via Ethernet or Wi‑Fi, and control through VictronConnect, while allowing additional functionality to be added through USB accessories.

Key benefits

• Quad-core processor delivering Ekrano GX-class performance.
• Centralised monitoring of battery status, PV production, generator, mains input and consumption.
• Supports up to 25 VE.Direct devices in total, including devices connected through USB.
• Two VE.Direct ports and two VE.Can ports for integration with Victron equipment and CAN-bus devices.
• Remote monitoring, configuration, alerts and firmware updates through Victron Remote Management.
• Access through VictronConnect, a web browser, local Wi‑Fi and the Android GX WiFi Display.
• Expandable with VE.Bus, analogue and digital inputs, relays and other functions through optional USB accessories.
• Compact enclosure suitable for wall mounting or DIN-rail mounting with an additional adapter.
• Integration with marine multifunction displays and NMEA 2000 systems.

Applications

Nucleo GX is intended for energy storage systems, off-grid and backup power installations, marine systems and other Victron solutions that require centralised control and remote monitoring. It is particularly suitable for installations built around Multi RS and other VE.Can-based components.
