xVictron Energy Cerbo GX MK2 | BPP900451100
The Cerbo GX MK2 is Victron Energy's second-generation GX communications device, designed to monitor and control Victron systems via the VRM online portal, local touchscreen displays, and third-party integrations. It suits professional installers building off-grid, hybrid, and marine energy systems where centralised monitoring and control are required.
Key Features
- Connects to the Victron VRM portal for remote monitoring, data logging, and system alerts over the internet.
- Two VE.Direct ports for direct connection to MPPT solar charge controllers, BMV battery monitors, and other VE.Direct devices.
- VE.Bus port for communication with MultiPlus and Quattro inverter-chargers, enabling remote switching and configuration.
- VE.Can port supports Lynx Smart BMS, Lynx Distributor, and compatible CAN-bus battery systems.
- Built-in Bluetooth for wireless connection to the VictronConnect app during commissioning and setup.
- HDMI output and USB ports allow connection of the GX Touch 50 or GX Touch 70 display for local touchscreen control.
- Supports two-way communication with compatible managed battery systems including BYD, Pylontech, and others via CAN-bus.
- Digital inputs for generator auto-start, tank level sensors, and dry-contact alarms.
- Relay outputs for generator control and general-purpose switching.
- MK2 revision includes hardware improvements over the original Cerbo GX for improved long-term reliability.
Product Overview
The Cerbo GX MK2 acts as the communications hub of a Victron system. It collects data from all connected Victron devices, displays system status locally (via an optional GX Touch display), and transmits data to the VRM portal. From VRM, installers and system owners can view historical data, configure alerts, and issue remote commands. This makes it practical for monitoring installations that are not easily accessible, such as remote off-grid sites, boats, or commercial plant rooms.
The range of ports on the Cerbo GX MK2 covers the full Victron product ecosystem. VE.Bus handles inverter-charger communication, VE.Direct covers MPPT controllers and battery monitors, and VE.Can connects managed battery systems and Lynx components. A USB port also allows connection of a USB-to-VE.Direct cable for additional devices. The digital inputs accept signals from tank level sensors, temperature sensors, and generator run contacts, consolidating all system data into a single interface.
The MK2 designation reflects a hardware revision to the original Cerbo GX. The firmware and software feature set is identical to the original, so existing VRM configurations, documentation, and integrations apply without modification. The MK2 is the current production version and replaces the original Cerbo GX in Victron's product line.

Installation Notes
The Cerbo GX MK2 should be installed by a qualified electrician or accredited solar installer familiar with Victron systems. The device accepts a wide DC input range (8 to 70 V), making it compatible with 12 V, 24 V, and 48 V battery systems without additional converters. VE.Bus configuration for MultiPlus and Quattro inverter-chargers requires VEConfigure or VictronConnect and appropriate installer access. For grid-connected systems, ensure the installation complies with G98 or G99 requirements as applicable. CAN-bus connections to managed battery systems must use the correct termination and cable type as specified in the Victron Cerbo GX manual. Internet connectivity for VRM can be provided via Ethernet, USB Wi-Fi adapter, or a GX LTE 4G modem (sold separately).
