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 1 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.
Take Control of Your Energy
Equip your MultiPlus-II system with the precision it needs to deliver reliable, efficient power management. Order the Victron Current Transformer today and unlock the full potential of your inverter-charger.

WARRANTY
Victron Energy Limited Warranty Policy
Victron Energy warrants its products to be free from defects in workmanship and materials for a period of 5 years from the date of purchase by the end user, with a maximum of 66 months from the Victron Energy invoice date. Exceptions on this are: lead acid batteries; 2 years from date of purchase by the end user, with a maximum of 30 months from the Victron Energy invoice date, Lithium-ion batteries; 3 years from date of purchase by the end user. In addition to this proof of correct battery usage is required when making a battery warranty claim.
During this period, Victron Energy will, at its option, repair or replace the defective product free of charge. The warranty does not include performing or reimbursing de‐installation, transportation and re‐installation. This warranty will be considered void if the unit has suffered any physical damage or alteration, either internally or externally, and does not cover damages arising from improper use like:
• Reverse of battery polarity.
• Inadequate connection.
• Mechanical shock or deformation.
• Contact with liquid or oxidation by condensation.
• Use in inappropriate environment (dust, corrosive vapor, humidity, high temperature, biological infestation...).
• Breakage or damage due to lightning.
• Connection terminals and screws destroyed or other damages, like overheat, due to insufficient tightening.
• For any electronical breakage except due to lightning (reverse polarity, over‐voltage due to external cause), the state ofthe internal control diode and of the inputs/output X and Y capacitors determine the warranty.
This warranty will not apply where the product has been misused, neglected, improperly installed, or repaired by anyone else than Victron Energy or one of its authorized Qualified Service Partners. In order to qualify for the warranty, the product must not be disassembled or modified.
Repair or replacement are our sole remedies and Victron Energy shall not be liable for damages, whether direct, incidental,special, or consequential, even caused by negligence or fault.
Victron Energy owns all parts removed from repaired products. Victron Energy uses new or reconditioned parts made by various manufacturers in performing warranty repairs and building replacement products.
