Key Features & System Integration

• Integrated GX Device: Includes an internal communication hub (equivalent to a Cerbo GX) for system configuration, monitoring, and control. It enables connection to the Victron Remote Management (VRM) portal for remote access and data logging.
• PowerControl & PowerAssist: Prevents overloading limited AC sources (such as a generator or shore power) by automatically adjusting battery charging. PowerAssist supplements the source with battery power during peak demand periods.
• Two AC Outputs: The main output features "no-break" functionality, taking over the supply to connected loads in less than 20 milliseconds during a grid failure. The second output is live only when AC is available on the input, preventing non-essential loads (like water heaters) from discharging the battery.
• Parallel and Three-Phase Operation: Up to 6 units can be connected in parallel to increase power output. Three units of the same model can also be configured for three-phase output.
• External Current Sensor Option: Allows for the extension of PowerControl and PowerAssist functions to 50 A or 100 A.
• Programmable Relay: Features a relay that can be configured for general alarms, DC under-voltage, or generator start/stop functions.
