Current Transformer - Victron Energy - 100A:50mA - 5m
This Victron Energy current transformer is designed for use with MultiPlus-II and MultiGrid-II sys...This Victron Energy current transformer is designed for use with MultiPlus-II and MultiGrid-II systems. It allows for the implementation of PowerControl and PowerAssist functions, and can optimize self-consumption with external current sensing. The transformer measures current indirectly, with an output current proportional to the main conductor's current. It is designed for use on a single conductor and comes with a 5-meter cable that is wire-ended (no connector). The nominal current is 100A (max 120A), with an output current of 50mA. The maximum conductor diameter is 12-13mm. Cable length is 5 meters. Technical specifications: Nominal current: 100 A (max. 120 A), Maximum conductor diameter: 12-13 mm, Output current: 50 mA, Cable length: 5 m.
This Victron Energy CTR120000550 current transformer is designed for users of MultiPlus-II and MultiGrid-II systems who want to enhance their energy management capabilities. Its key benefit is enabling advanced features like PowerControl and PowerAssist, along with optimizing self-consumption through external current sensing. A key consideration is that it measures current indirectly and requires careful installation on a single conductor. This transformer provides an output current proportional to the main conductor's current, up to a nominal 100A.

FAQs
What is the maximum current this transformer can measure?
The Victron Energy CTR120000550 has a nominal current rating of 100A, with a maximum allowable current of 120A.
What is the output current of this transformer?
The transformer provides an output current of 50mA, which is proportional to the current flowing through the monitored conductor.
Can this transformer be used with any Victron inverter?
This specific transformer (CTR120000550) is designed for use with Victron Energy MultiPlus-II and MultiGrid-II systems.
What is the maximum diameter of the conductor it can fit around?
The transformer is designed to fit around conductors with a maximum diameter of 12-13mm.
Does the cable come with a connector?
No, the included 5-meter cable is wire-ended, meaning it does not have a pre-attached connector and requires direct wiring.
How do I install the current transformer?
Install by clamping it around a single conductor and connecting the wire-ended cable to the designated sensing input on a compatible Victron inverter, then configure it via software.
What does 'indirect current sensing' mean?
It means the transformer measures the magnetic field generated by the current flowing through the conductor, rather than directly measuring the current itself. This is a safe and non-invasive method.
Troubleshooting
Current readings are inaccurate or zero
Ensure the transformer is correctly clamped around a single conductor and that the connection to the inverter is secure. Verify that the transformer settings are correctly configured in the inverter's software.
PowerControl/PowerAssist functions not working
Check the physical connection of the transformer's cable to the inverter. Ensure the correct model and settings for the current transformer are selected in the inverter's configuration.
Transformer not recognized by the inverter
Verify that the inverter firmware is up-to-date and supports the current transformer. Double-check the wiring of the transformer's cable to the appropriate sensing port on the inverter.
