Victron 5m 100A:50mA Current Transformer for MultiPlus-II

DESCRIPTION

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 5m 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 5m 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

Direct Customers

Victron Energy provides the following warranty to any direct customer (OEM, distributor or dealer) in relation to any products that Victron Energy has directly sold to the direct customer. This warranty is not an end-user warranty between Victron Energy and an end-user, and end-users shall not have any rights or remedies under this limited warranty towards Victron Energy directly. The direct customer shall, in turn, ensure that the end-user is provided with a warranty identical to this warranty, subject to applicable local mandatory law.

End-Users

Victron Energy may also provide a warranty directly to end-users, in which case the below warranty conditions equally apply to such warranty. In that case, end-users shall claim their warranty at their place of purchase or through the original direct customer of Victron, which can be found through the support section on Victron’s website https://www.victronenergy.com/support. Hence, the direct customer shall on behalf of Victron Energy deal with any warranty claims made under any warranty that Victron Energy may provide directly to end-users. This support section on Victron’s website https://www.victronenergy.com/support will provide further guidance on the procedure for end-users to make a claim under this limited warranty.

If the end-user is a consumer – a natural person who is acting for purposes which are outside that person's trade, business, craft or profession – the following applies. The rights and remedies granted to the consumer under this limited warranty are without prejudice to the consumer’s statutory rights. Furthermore, the consumer is entitled by law to remedies from the seller free of charge in the event of a lack of conformity of the goods (such as repair, replacement, price reduction or rescission), which remedies are not affected by this limited warranty.

Warranty

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 original 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 original end-user, with a maximum of 30 months from the Victron Energy invoice date, Lithium batteries: 3 years from date of purchase by the original end-user, with a maximum of 42 months from the Victron Energy invoice date. In addition to this, proof of correct battery usage is required when making a battery warranty claim.

For a 10% surcharge on the current net price for products that came with a 5-year warranty, an additional 5 years of warranty can be purchased by Victron’s direct customers, bringing the total warranty to 10 years. Warranty extensions need to be applied for ultimately one year before the expiration of the original term. Victron may ask proof that the product was still functional at the time of purchase of the extended warranty.

During the warranty period, Victron Energy will, at its discretion, repair, replace or (partly) credit 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:

  • Reversed battery polarity.
