Victron Cerbo-S GX

The Victron Energy Cerbo-S GX is a powerful communication and monitoring centre designed to bring compatible Victron equipment together into one centrally managed system. It collects operating information from connected inverter/chargers, solar controllers, battery monitors, managed batteries and other supported devices, giving users a clear overview of their complete power installation.

When connected to the internet, the Cerbo-S GX can upload system information to the free Victron Remote Management portal, allowing users and authorised technicians to monitor performance, review historical data, receive alarm notifications and access supported settings remotely.

For local operation, the Cerbo-S GX can be paired with a separately available Victron GX Touch display or accessed using Remote Console from a compatible phone, tablet or computer.

Centralised System Monitoring

The Cerbo-S GX acts as the communication hub for a compatible Victron power installation. It collects information from connected equipment and presents the data through a unified interface.

Depending on the system configuration, users may be able to monitor:

• Battery voltage
• Battery current and power
• Battery state of charge
• Solar charging output
• Daily and historical solar yield
• Inverter and charger operating status
• AC input and output power
• Grid, generator or shore-power supply
• DC system loads
• Active alarms and warnings
• Generator operating status
• Individual connected-device information
• Overall system power flow

The information available depends on the equipment installed and its communication capabilities.

Victron Remote Management

When connected to the internet and registered with the Victron Remote Management portal, the Cerbo-S GX enables remote access to supported system information.

Through VRM, users may be able to:

• View live system information
• Review historical graphs and performance data
• Monitor battery and solar conditions
• Receive email or push notifications for configured alarms
• Use Remote Console to access the GX interface
• Share system access with an installer or technician
• Diagnose certain faults remotely
• Change supported settings
• Download system reports and data

Remote access requires a suitable internet connection through Ethernet, Wi-Fi or a compatible externally connected network device.

Communication Connections

The Cerbo-S GX supports several Victron communication methods, allowing it to integrate with a wide range of equipment.

VE.Direct

VE.Direct ports can connect compatible Victron products such as:

• SmartSolar and BlueSolar MPPT controllers
• BMV battery monitors
• SmartShunt battery monitors
• Selected Phoenix inverters
• Other VE.Direct-equipped products

VE.Bus

The VE.Bus connection supports compatible Victron inverter/chargers and inverter systems, including selected:

• MultiPlus
• MultiPlus-II
• Quattro
• VE.Bus inverter systems

VE.Can

VE.Can supports compatible Victron devices and selected managed batteries. The correct CAN profile, communication speed, terminators and manufacturer-specific cable must be used.

The Cerbo-S GX does not provide the same dedicated CAN arrangement as every standard Cerbo GX version. Confirm the required CAN connections when designing systems that need both VE.Can equipment and a CAN-bus battery connection.

USB

USB ports may be used with supported accessories and communication interfaces, including VE.Direct-to-USB interfaces where additional VE.Direct connections are required.

Optional GX Touch Display

The Cerbo-S GX does not include a built-in screen. For a permanent local touchscreen, it can be paired with a separately available:

• Victron GX Touch 50
• Victron GX Touch 70
• Compatible GX Touch flush-mount model

The GX Touch connects directly to the Cerbo-S GX and provides a clear, full-colour interface for monitoring system performance and accessing supported settings.

Alternatively, the system can be accessed using Remote Console from a compatible device connected through the local network or VRM.

Generator Control

The programmable relay outputs can be used for supported control applications, including automatic generator start and stop when installed with compatible generator-control equipment.

Generator operation may be configured according to conditions such as:

• Low battery state of charge
• Low battery voltage
• High system load
• Scheduled run times
• Loss of AC input
• Manual remote request

Generator compatibility and additional wiring requirements must be confirmed before installation. The Cerbo-S GX relay generally provides a control signal and does not directly operate a generator starter motor or other high-current load.

Digital Inputs

Digital inputs allow the Cerbo-S GX to monitor supported external switches and status signals. Depending on the configuration, these may be used for functions such as:

• Door or hatch status
• Bilge-pump operation
• Generator running indication
• Alarm contacts
• Manual switches
• Other compatible digital signals

Input wiring and software configuration must match the required function.

Cerbo-S GX Compared with Cerbo GX

The Cerbo-S GX provides the core monitoring, control, networking and VRM functionality used in many Victron installations. However, it is a simplified model and does not include all of the direct sensor connections found on the full Cerbo GX.

In particular, the Cerbo-S GX does not provide the same built-in connections for:

• Resistive tank-level senders
• Direct temperature sensors
• Dedicated BMS-CAN connectivity

If these functions are required, consider the standard Cerbo GX or suitable external compatible interfaces. System requirements should be confirmed before selecting the GX model.

Typical Applications

The Victron Cerbo-S GX is suitable for:

• Caravans and camper trailers
• Motorhomes
• Marine and boating electrical systems
• Four-wheel drives
• Food trucks and mobile businesses
• Service and commercial vehicles
• Off-grid homes and cabins
• Residential energy-storage systems
• Backup-power systems
• Solar and battery installations
• Generator-assisted power systems
• Remote equipment and telecommunications sites

Installation Information

Install the Cerbo-S GX in a dry, protected and ventilated location close enough to the connected equipment for safe communication-cable routing.

The unit must be supplied through a correctly protected DC circuit. Communication cables should be routed away from high-current wiring where practical and protected against heat, moisture, abrasion and strain.

Each connected product must use the correct communication cable. VE.Direct, VE.Bus, VE.Can and CAN-bus BMS cables are not interchangeable simply because some use similar-looking connectors.

Please Note

The Cerbo-S GX is a monitoring and communication device. It does not replace an inverter, charger, solar controller, battery monitor or battery-management system.

The GX Touch display, communication cables, terminators, sensors and internet connection are sold separately unless specifically stated as included. Compatibility depends on the exact equipment models, firmware versions, communication protocols and overall system design. Professional installation and commissioning are recommended for complex or high-power systems.
