Victron Energy Cerbo GX (MK2)

The Cerbo GX MK2 is the hub of a Victron electrical system. Your battery monitor, solar charge controllers, inverter/charger, DC-DC chargers, and BMS all connect to it. You can then see and control the whole system from one screen in your van or from your phone anywhere with an internet connection. It runs Victron’s Venus OS and replaces both the original Cerbo GX and the Cerbo-S GX.

Ways to view and control your system

• In the van: add a touchscreen. Choose the GX Touch 50 (5″) or GX Touch 70 (7″) for surface mounting, or the GX Touch 50 Flush or GX Touch 70 Flush for a clean, recessed install. Each connects with a single HDMI cable.
• Remotely: use Victron Remote Management (VRM), Victron’s free online portal and app, over WiFi, Ethernet, or the GX LTE 4G-A cellular modem when you’re out of WiFi range.
• From your phone: use the free VictronConnect app.
• On a boat: use a compatible marine MFD such as Garmin, Raymarine, Navico, or Furuno.

What you can monitor and control

• Battery state of charge, power consumption, and charging from solar, alternator, generator, and shore power
• Tank levels and temperatures
• Shore power input current limit and inverter/charger mode (on, off, charger only, inverter only)
• Automatic generator start/stop, and relay-triggered loads such as a cooling fan
• Alerts, alarms, and remote firmware updates, so many problems can be diagnosed and fixed without visiting the vehicle

What’s new in the MK2

• Two full VE.Can ports (the original had one VE.Can and one BMS-Can). One port is galvanically isolated, which helps in larger CAN networks with many devices.
• All three USB ports fully functional, for accessories like the GX LTE 4G-A modem, a GPS receiver, or the GX Tank 140
• Digital inputs that accept pulse signals, for flow meters and similar sensors
• Rotated RJ45 ports, so cables are easier to unplug in tight installs
• The same dual-core processor, 1 GB RAM, and enclosure as the original, so it’s a direct drop-in replacement

Connections

• 3 × VE.Direct (for SmartShunt, MPPTs, and other VE.Direct devices)
• 2 × VE.Bus (for MultiPlus and Quattro inverter/chargers)
• 2 × VE.Can, one isolated (for VE.Can MPPTs, the Lynx Smart BMS NG, and NMEA 2000 networks)
• 3 × USB
• 4 × resistive tank level inputs (US and EU senders)
• 4 × temperature inputs
• 4 × digital inputs
• 2 × programmable relays
• Ethernet, WiFi, and Bluetooth
• HDMI for the GX Touch display
• Supply voltage: 8–70 VDC (12, 24, and 48 V systems)

Our take for van builders

In a van, the Cerbo GX MK2 is what makes a Victron system easy to live with. It shows everything on one screen instead of in several Bluetooth apps, and VRM lets you check your battery from the trailhead or while the van sits in storage. The second VE.Can port matters most if you’re running Victron NG lithium batteries with a Lynx Smart BMS NG while also connecting CAN-based devices like an alternator regulator or VE.Can solar chargers.
