Victron Energy Current Transformer 100A:50mA for MultiPlus-II (5m) - CTR110000550

The Victron Energy CTR110000550 Current Transformer is an external AC current-sensing accessory designed for compatible MultiPlus-II and MultiGrid-II inverter/charger systems. It provides a 100A:50mA current-transformer interface for implementing supported Victron functions including PowerControl, PowerAssist, and self-consumption optimization with external current sensing. :

This model belongs to Victron's CTR11 series and uses a jack-style connection. Victron distinguishes it from the CTR12 series, which uses wire-end termination, so the current-sense connection on the specific inverter/charger should be verified before installation.

Key Technology

• External AC Current Sensing
  Provides external current measurement for compatible Victron inverter/charger systems, allowing the system to monitor AC current at the selected measurement point.

• 100A:50mA Current Transformer
  Uses a 100A primary-to-50mA secondary current-transformer ratio matched to the designated Victron current-sensing application.

• PowerControl Support
  Supports compatible MultiPlus-II and MultiGrid-II installations configured to use Victron PowerControl for management of available AC input power.

• PowerAssist Support
  Provides external current sensing for supported PowerAssist configurations, allowing compatible inverter/chargers to respond to AC loading according to the configured system limits.

• Self-Consumption Optimization
  Can be used by compatible Victron systems to optimize self-consumption based on external AC current sensing. 

• CTR11 Jack-Style Connection
  The CTR11 series uses a jack connection, while Victron's corresponding CTR12 models terminate with wire ends. 

Best Uses

• Compatible MultiPlus-II Systems
  Designed for supported MultiPlus-II installations equipped with the appropriate jack-style external current-sense interface.

• MultiGrid-II Systems
  Suitable for compatible MultiGrid-II installations requiring external AC current measurement.

• PowerControl Applications
  Useful where AC current at an external measurement point must be incorporated into the inverter/charger's configured power-management strategy.

• PowerAssist Applications
  Provides current feedback for supported systems using PowerAssist to coordinate inverter assistance with available AC input power.

• Self-Consumption Systems
  Suitable for compatible energy-storage installations where external current sensing is used as part of the system's self-consumption control strategy.
