Victron Cerbo GX MK3 – System Monitoring & Control
Bring your energy system together with the Victron Cerbo GX MK3 (BPP900451130). This communication centre connects compatible inverter/chargers, solar chargers, battery monitors and other supported equipment, giving you a central place to monitor performance and manage your installation.
Whether you are managing an RV, a boat or an off-grid power system, the Cerbo GX helps you understand what your connected equipment is doing and access system settings locally or remotely.
Room for a Larger Connected System
The MK3 supports up to 25 connected VE.Direct devices, compared with 15 on the MK2. This gives you additional capacity for installations with multiple compatible solar chargers and battery monitors.
Three physical VE.Direct ports are provided. The total device limit includes connections made through USB using suitable interfaces; additional connection accessories may be required.
Monitor Locally or Remotely
Access the Remote Console through a compatible web browser on your local network. With an internet connection, use Victron’s VRM portal to view your installation remotely and access supported monitoring and configuration functions.
For a dedicated local display, pair the Cerbo GX MK3 with an optional GX Touch 50 or GX Touch 70. Displays and mounting accessories are sold separately.
Connect More Than Your Power Equipment
Expand your system overview with inputs for compatible tank senders, temperature sensors and digital signals. Two programmable relays provide options for supported control functions, with available settings depending on the relay and firmware.

More Headroom for Your Connected Energy System
The Victron Cerbo GX MK3 (BPP900451130) combines expanded device capacity with updated internal hardware. It retains the MK2’s compact enclosure and connection layout for RV, marine and off-grid energy systems.
What’s New
Reported hardware changes include a move from a dual-core Cortex-A7 processor to a quad-core Cortex-A53, and from 1 GB DDR3 to 1 GB DDR4 memory. Memory capacity remains the same; the memory generation changes.
Victron’s official specifications confirm an increase from 15 to 25 supported VE.Direct devices, including USB-connected devices. Both models retain three physical VE.Direct ports.
What That Means for Your System
The MK3 offers more room for connected equipment. Its reported processing improvements may also benefit more demanding installations, although actual performance depends on the connected devices, firmware and software running on the system.

Familiar Cerbo GX Features
Both models centralize monitoring and control of compatible equipment. Access Remote Console locally, add an optional GX Touch display, or connect to the internet for remote access through Victron VRM.
Available functions depend on connected equipment, firmware and configuration. Displays and additional connection accessories are sold separately.
Upgrading from the MK2
The matching dimensions and connection layout simplify physical replacement. However, settings must be manually configured on the new GX device. Record your connections and settings before removing the MK2.
Use Victron’s Replace GX Device procedure in VRM to preserve the existing installation’s historical data. This does not transfer the GX device’s settings, and a recording gap can occur during replacement.
First Configuration
Install current stable firmware, configure the connected equipment and check system readings. Verify battery monitoring, charging coordination, alarms, sensor inputs and relay-controlled functions.
After connecting to the internet, confirm that VRM receives data and remote access works correctly.
Is It the Right Upgrade?
Consider the MK3 for an expanding installation or one approaching the MK2’s device limit. If your MK2 already meets your needs, assess your planned additions and software requirements before replacing it.
