Description
xCurrent Transformer 100A:50mA for MultiPlus-II (20m) Wire-End
This current transformer is designed for use with the Victron MultiPlus-II inverter/charger, providing accurate AC current measurement via a 20-metre wire-end lead. It is intended for professional installers who need to monitor grid or generator current as part of a Victron energy management system.
Key Features
- 100A:50mA ratio provides accurate current sensing across typical residential and light commercial load ranges.
- 20-metre cable length gives flexibility in installations where the MultiPlus-II is mounted away from the main distribution board.
- Wire-end termination allows direct connection to the MultiPlus-II current transformer input without additional connectors.
- Designed specifically for compatibility with the Victron MultiPlus-II inverter/charger series.
- Clamp-style split-core design allows installation around an existing conductor without breaking the circuit.
- Lightweight at 0.7 kg, suitable for panel or enclosure mounting in fixed installations.
Product Overview
The MultiPlus-II uses current transformer inputs to monitor AC current on the grid or generator connection. This data feeds into the PowerControl and PowerAssist functions, allowing the MultiPlus-II to limit its own current draw or supplement supply without overloading the incoming connection. Accurate current sensing is therefore a functional requirement, not an optional extra.
The 100A:50mA ratio is suited to single-phase supplies up to 100A, covering the majority of domestic and small commercial installations. The 20-metre cable length is a practical consideration: in many installations the inverter is located in a utility room or garage while the consumer unit is elsewhere, and a short cable would not reach. This variant eliminates the need for cable extensions that could introduce measurement error.
The wire-end format means the installer connects directly to the CT input terminals on the MultiPlus-II. No proprietary connector is required at the device end, keeping the installation straightforward.

Installation Notes
This current transformer must be installed by a qualified electrician. It is intended for use on the AC input of a Victron MultiPlus-II and must be fitted around the correct conductor in accordance with Victron's wiring documentation for that unit. Incorrect installation will result in inaccurate current readings and may affect the operation of PowerControl and PowerAssist functions. For grid-connected systems in the UK, the overall installation must comply with G98 or G99 requirements as applicable. Do not install on conductors carrying voltages or currents beyond the rated specification of the transformer.
