The Victron Current Transformer 100A:50mA for MultiPlus-II is an essential accessory for installers and system integrators who want precise energy monitoring and improved control of grid-tied inverter charger systems. Designed specifically for use with Victron MultiPlus-II models, this transformer enables the system to measure AC current flow at the grid connection point, allowing accurate load balancing, export limitation, and consumption insight.
Constructed with a durable split-core ABS housing, the transformer is quick to install on existing wiring without disconnecting cables. Its 100 amp primary and 50 milliamp secondary ratio delivers reliable readings to the MultiPlus-II GX device, helping maintain safe operational limits. When used with Victron Energy’s ESS (Energy Storage System) settings, it allows the inverter charger to efficiently manage power flows between the grid, batteries, and connected loads.
For commercial, mobile, and off-grid B2B applications, this transformer supports system compliance where export limitation is required. It assists trade customers in reducing peak demand charges and preventing unwanted back feed. When combined with a GX device such as the Cerbo GX, the transformer’s data can be monitored remotely via the Victron VRM portal, giving installers and fleet managers real-time oversight and performance visibility.
The compact form factor helps save space on crowded distribution boards, while clear labelling and a fixed cable make installation straightforward for qualified professionals. Once fitted, the transformer continually feeds system data to optimise charge and discharge cycles, improve battery health, and support stable grid interaction. This makes it ideal for energy storage installations, hybrid systems, and commercial backup power solutions.
Whether deploying multiple units across sites or building a single advanced energy hub, this Victron transformer ensures accurate power measurement and dependable operation over long service lifecycles. It is engineered for trade environments where reliability and system efficiency are top priorities.
Options available for cable length: 1m, 5 metres and 20 metres
