Victron Energy Cerbo GX MK2 Communications Center for Advanced Power Management

Cerbo GX MK2

Victron's Cerbo GX MK2 is the most commonly used GX product. This communications center has hardware revision 2 with two VE.Can ports, 3 USB host ports, and digital input pulse counting.

The Cerbo GX MK2 Is Different from the Cerbo Gx since It Has:

• Two fully functional CAN bus ports- VE.Can 1 and VE.Can 2. Instead of one VE.Can and one BMS-Can port


• VE.Can 1 is isolated (on previous models, there was no isolated CAN-bus port)


• RJ-45 sockets have been rotated 180 degrees, so it's easier to take the cables out


• All three USB ports are fully functional (instead of two functional and one for power (to a GX Touch) only)


• Digital inputs can do pulse counting

This communication center allows users to always have perfect control over the system from wherever they are and maximizes its performance. Connect through the Victron Remote Management (VRM) portal, or access directly, using the separate GX Touch 50, an MFD, or Victron's VictronConnect app thanks to its added Bluetooth capability. This latest addition to the GX range combines all the best of connectivity, redefining smart power solutions in every way.

Perfect Monitoring Control

Instantly monitor the battery state of charge, power consumption, and power harvest from PV, generator, and mains, or check tank levels and temperature measurements. Easily control the shore power input current limit, (auto)start/stop generator(s), or change any setting to optimize the system. Follow up on alerts, perform diagnostic checks, and resolve challenges remotely. The Cerbo GX MK2 turns any power challenge into an effortless experience.

Maximize Your System Performance

The Cerbo GX MK2 maximizes the performance of a system's components in real time and keeps them in perfect tune. This enclosure has two fully functional CAN bus ports, called VE.Can 1 and VE.Can 2. Instead of one VE.Can and one BMS-Can port. VE.Can 1 is isolated. In the previous models, there was no isolated canbus port. This can be useful where a Lynx Smart BMS (VE.Can connection) as well as an RV-C port are required.

Expand Your View

The (optional) GX MK2 Touch 50 display gives users an instant overview of their system and adjust settings in the blink of an eye. Its super slim 5-inch waterproof design, top-mountable setup, and simple installation bring a lot of flexibility when creating a crisp and clean dashboard.

Simple Mounting Configuration

The Cerbo GX MK2 is now optimized to more than meet the standards of installer professionals. The device is easily mountable on a DIN-Rail (with DIN35 adapter small, not included), and its separate touchscreen can now be bolted on top of a dashboard, eliminating the need to create perfect cut-outs (like with the Color Control GX MK2). It is connected through just one cable, taking away the hassle of having to bring many wires to a dashboard. Its new Bluetooth feature enables a quick connection and configuration via the VictronConnect app.

Outsmart Any Power Challenge

The Cerbo GX MK2 serves endless purposes, extending perfect control to the most diverse applications. For solutions including generators, such as marine, or backup off-grid, it will auto-start/stop the generator, or delay ignition until the end of quiet periods. It keeps backup batteries at 100% for energy storage systems, kicks in during power cuts, and diverts excess (solar) power to self-consumption, saving users money. For RVs and emergency vehicles, it keeps vital systems functioning flawlessly. But thats just to name a few...
