Victron Cerbo GX MK2 System Monitoring Hub

The Victron Cerbo GX MK2 is the central communication hub that brings a Victron power system together. Instead of checking individual components one at a time, the Cerbo GX gives you one place to monitor and control key system information, including battery state of charge, inverter/charger activity, solar charging, shore power, generator input, tank levels, temperature measurements, and system alerts.

For RV, van, marine, overland, and off-grid customers, this is the piece that turns a collection of Victron components into a connected power system. Paired with a GX Touch display, a local network connection, or the Victron Remote Management portal, the Cerbo GX helps you understand what your system is doing, adjust key settings, and catch issues earlier.

The MK2 version of the Cerbo GX, part number BPP900450110, includes 3 VE.Direct ports, 2 paralleled VE.Bus RJ45 sockets, two VE.Can ports, Ethernet, WiFi, Bluetooth for setup and networking configuration, 4 tank level inputs, 4 temperature inputs, 4 digital inputs with pulse counting, and 2 programmable relays.

Product Role

The Victron Cerbo GX MK2 helps monitor, connect, and control major components in a mobile power system.

It can help support:

• Centralized visibility for batteries, inverter/chargers, solar controllers, and AC power sources
• Remote monitoring and diagnostics through VRM
• Generator start/stop control when properly configured
• Tank level and temperature monitoring
• GX Touch display integration for a clean local dashboard

Why It Matters

A well-built power system should be easy to understand once it is installed. The Cerbo GX gives owners and installers a clear view of how power is moving through the system, whether batteries are charging correctly, how much solar is being produced, what loads are being used, and whether a shore power or generator source is active.

It also helps with support and troubleshooting. With internet connectivity, system data can be sent to VRM for remote monitoring, Remote Console access, data logging, alerts, and software updates. Ethernet and WiFi can both be used for internet connectivity, while the built-in WiFi access point can provide local Remote Console access. (Victron Energy)

Best For

• RV and van Victron power systems that need one central monitoring hub
• Marine and yacht systems with battery, tank, temperature, generator, and inverter/charger monitoring needs
• Off-grid cabins and mobile workspaces using Victron inverter/chargers and solar controllers
• Systems that need VRM remote monitoring and support visibility
• Installations using a GX Touch 50 or GX Touch 70 display
• Power systems where generator start/stop control or relay-based automation is part of the design

Key Features

• Central Victron communication hub: Connects compatible Victron components so the system can be monitored and managed from one interface.
• VRM remote monitoring support: Enables remote visibility, data logging, alerts, and Remote Console access when connected to the internet.
• GX Touch compatible: Works with GX Touch 50 and GX Touch 70 displays for a clean, dedicated local system screen.
• Multiple Victron communication ports: Includes VE.Bus, VE.Direct, and VE.Can connectivity for integrating inverter/chargers, solar controllers, battery monitors, and other compatible devices.
• Tank and temperature monitoring: Four resistive tank inputs and four temperature sense inputs help bring more of the RV, marine, or off-grid system into one dashboard.
• Programmable relays: Two NO/NC relays can support functions such as alarm output, generator start/stop, tank pump control, temperature-controlled relay operation, or manual operation depending on configuration.
• WiFi, Ethernet, and Bluetooth setup: Ethernet and WiFi support internet connectivity and Remote Console functions, while Bluetooth is used for initial connection and networking setup. (Victron Energy)

System Integration

The Cerbo GX does not invert power, charge batteries, or replace proper system protection. Its role is communication, monitoring, control, and visibility. In a typical MobileMustHave-style Victron system, it works alongside components such as MultiPlus or Quattro inverter/chargers, SmartSolar charge controllers, Lynx distribution, compatible lithium batteries, battery monitors, tank sensors, temperature sensors, and GX Touch displays.

For mobile installations, the Cerbo GX is often the difference between having power equipment installed and having a power system you can confidently understand. It gives customers and support teams a shared view of the system, which is especially valuable when troubleshooting charging behavior, shore power limits, generator operation, battery status, or solar performance.

MobileMustHave Expert Note

MobileMustHave designs and supports real RV, marine, van, and off-grid power systems, not just individual parts. The Cerbo GX is one of the most important pieces in a professional Victron installation because it gives owners, installers, and support teams the visibility needed to understand system behavior and make better decisions after the install.
