Common Questions What is the primary function of the Victron Cerbo GX MK2? The Cerbo GX MK2 serves as the central communication hub for your Victron Energy power system, allowing you to monitor and control all connected components from a single interface. How can I monitor my Victron system with the Cerbo GX MK2? You can monitor your system remotely via the Victron Remote Management (VRM) portal over the internet, or locally using an optional GX Touch display or the VictronConnect App on your smartphone/tablet via Bluetooth. Is a display included with the Cerbo GX MK2? No, the Cerbo GX MK2 does not include a built-in display. It is designed to be paired with optional Victron GX Touch 50 or GX Touch 70 touchscreen displays, or accessed via the VRM portal or VictronConnect App. Can the Cerbo GX MK2 be used in marine applications? Yes, the Cerbo GX MK2 is well-suited for marine applications, offering an NMEA 2000-out function to integrate Victron system data with marine Multi-Functional Displays (MFDs). Installation Notes The Cerbo GX MK2 can be surface mounted or installed on a DIN rail (requires a separate DIN35 adapter). Connect all compatible Victron Energy devices (inverters, solar chargers, batteries) to the Cerbo GX MK2 using the appropriate VE.Bus, VE.Direct, or VE.Can ports. Ensure a stable 8-70V DC power supply is connected to the unit. For remote monitoring, connect the Cerbo GX MK2 to the internet via its Ethernet port or built-in Wi-Fi. Initial configuration can be performed quickly via Bluetooth using the VictronConnect App. Before You Buy Verify compatibility with your existing Victron Energy system components to ensure seamless integration. Consider whether you require a local display; the GX Touch 50 or GX Touch 70 are optional accessories and are not included. Ensure your power system can provide a stable 8-70V DC supply for the Cerbo GX MK2. For DIN rail mounting, a DIN35 adapter is required and sold separately. Familiarise yourself with the VictronConnect App for easy setup and monitoring. Always refer to the manufacturer's official documentation for detailed specifications, installation guidelines, and system compatibility. Victron Energy products typically carry a 5-year manufacturer warranty.
