Product overview

The Cerbo GX MK2 acts as the communications hub of a Victron installation. It collects data from connected Victron devices, shows system status locally through an optional GX Touch display, and sends data to the VRM portal, where installers and owners can review history, set alerts, and issue remote commands. That makes it useful for sites that are hard to reach, such as remote off-grid installations, boats, or plant rooms.

Digital inputs accept signals from tank level sensors, temperature sensors, and generator run contacts, so all system data comes together in one interface. Relay outputs handle generator control and general-purpose switching.

MK2 revision

The MK2 designation marks a hardware revision of the original Cerbo GX. Firmware and software are unchanged, so existing VRM configurations, documentation, and integrations carry over without modification. The MK2 is the current production version and replaces the original Cerbo GX.
