Victron Cerbo GX Communications Center w/ BMS-CAN Port, Tank Level Inputs, Digital Inputs, and Temperature Sense

The Victron Cerbo GX Communications Center with BMS-CAN Port, Tank Level Inputs, Digital Inputs, and Temperature Sense is the backbone of modern marine electrical system management. Built by Victron Energy, this compact hub centralizes monitoring and control for anglers, cruisers, and boaters who demand real-time visibility into battery health, fuel and water tank levels, and auxiliary systems. Whether you're running a multi-day offshore expedition or anchoring in remote waters, the Cerbo GX eliminates guesswork about your vessel's power reserves and consumables—critical intelligence when you're far from shore.

At its core, the Cerbo GX bridges your battery management system (BMS) via CAN bus protocol, capturing detailed charge state, voltage, current, and temperature data from Victron lithium or lead-acid banks. Its dedicated tank level inputs accept analog signals from capacitive or resistive sensors, translating fluid depth into precise percentage readouts on your helm display or mobile device. Digital inputs allow integration of binary status signals—bilge pump alerts, shore power connection status, engine run hours—while onboard temperature sensors monitor battery health and compartment conditions. The system's compact footprint (5 x 3 x 9 inches, under one pound) fits neatly in engine bays or electrical lockers without consuming valuable cabin space.

Serious cruisers and tournament anglers benefit most from this integration hub, particularly those with hybrid power systems combining alternators, solar, and battery banks. The Cerbo GX pairs seamlessly with Victron's ecosystem—inverters, chargers, MPPT controllers, and the free VRM portal for remote monitoring via smartphone or web browser. Installation requires basic marine wiring knowledge and integration into your 12V or 48V electrical architecture; Victron documentation supports DIY builders and professional installers alike. For vessels equipped with CAN-capable battery management systems and multiple tank sensors, the Cerbo GX transforms scattered data into actionable insights, helping you maximize endurance and prevent unexpected power or fuel emergencies on the water.
