Accurate Current Sensing for Your Victron Energy MultiPlus-II System

The Victron Energy 400A:50mA Current Transformer is designed specifically to expand the capability of your MultiPlus-II or MultiGrid-II inverter/charger. By providing external current sensing, this essential accessory allows your system to accurately measure power drawn from or fed back into the grid. It is the ideal solution for users wanting to implement advanced Victron features such as PowerControl, PowerAssist, and Energy Storage System (ESS) self-consumption optimisation.

Optimise Self-Consumption and ESS

For grid-connected and hybrid energy setups, knowing exactly what is happening at the grid connection point is critical. When installed at the main switchboard, this current transformer communicates real-time grid usage data back to the MultiPlus-II. This allows the system to intelligently adjust battery charging or discharging to minimise grid power usage, thereby maximising the self-consumption of your generated solar energy.

• High-Capacity Sensing: 400A primary current to 50mA secondary current ratio for large electrical loads.
• Long Reach: Includes a generous 10-metre cable, providing flexible installation options between your main switchboard and the inverter.
• Wire-End Connection: Features stripped and tinned wire ends designed for secure connection into the direct push-in terminals on compatible MultiPlus-II models.
• Advanced System Control: Essential for activating PowerControl and PowerAssist features, protecting limited AC supplies such as generators or shore power.

Seamless Integration and Installation

This specific model (CTR140050100) is built with wire-end connections rather than a jack plug, ensuring compatibility with hardwired terminal configurations found on select MultiPlus-II and Quattro-II units. The robust 10-metre cable length allows for neat cable management and versatile positioning in complex residential, marine, or off-grid installations.

Reliable Victron Quality

Designed to integrate perfectly within the Victron ecosystem, this current transformer delivers the high-speed data necessary for the inverter to react instantaneously to changing load conditions. Whether you are managing peak loads on a remote property or setting up a sophisticated ESS to reduce electricity bills, this sensor is a critical component for smooth operation.

Maximise the efficiency and control of your power management system with the reliable precision of the Victron Energy 400A:50mA Current Transformer.
