Victron 100A:50mA Split-Core Current Transformer for MultiPlus-II

Precision External Current Sensing for Advanced Energy Management

The Victron Current Transformer enables precise external current sensing for compatible MultiPlus-II and MultiGrid-II inverter-charger systems. With a 100A:50mA ratio, it provides the critical measurement data needed to implement PowerControl and PowerAssist features, preventing generator or shore power overload while maximising available AC power. It also optimises self-consumption by accurately monitoring grid import and export, allowing your system to make intelligent decisions about battery charging and load support.

Unlike generic current transformers, this unit is factory-calibrated with a fixed cable length of 20 m to ensure measurement accuracy. The split-core design allows for quick, non-invasive installation around existing conductors without disconnecting wiring, reducing downtime and installation complexity. The cable is terminated with a standard 3.5 mm headphone jack for direct plug-and-play connection to the MultiPlus-II, eliminating the need for additional adapters or complex wiring.

Key Features

• 100A:50mA transformation ratio for accurate current measurement
• Split-core design for easy retrofitting without disconnecting cables
• Factory-calibrated cable ensures measurement precision
• 3.5 mm jack for direct connection to MultiPlus-II and MultiGrid-II
• Enables PowerControl and PowerAssist to prevent overload and optimise AC input
• Supports self-consumption optimisation through external current sensing
• Rugged construction for reliable performance in demanding environments

Reliable Performance for Critical Power Systems

Designed for single-phase monitoring, this current transformer measures current only, not voltage, and is intended for use with older MultiPlus-II units that require an external sensor for advanced functions. The robust housing and high-quality ferrite core ensure stable, repeatable measurements, reducing the risk of system errors caused by inaccurate current data. By providing real-time feedback to the inverter-charger, it helps protect your installation from unexpected power interruptions and improves overall energy efficiency.

Applications

This current transformer is essential for installations where the MultiPlus-II must dynamically manage AC input current, such as in marine, RV, and off-grid backup systems. It is particularly valuable when connected to a limited shore power supply or generator, where exceeding the available current could trip breakers or damage equipment. By enabling PowerAssist, the inverter can supplement the AC source with battery power during peak demand, ensuring uninterrupted operation of critical loads.

Installation Notes

The cable length is calibrated at the factory and must not be extended or shortened, as this will affect measurement accuracy. The split-core clamp simply opens and closes around the conductor, making it suitable for both new and retrofit installations. Ensure the core is fully closed and latched for reliable operation.
