Myenergi Current Transformer (CT Clamp) with 5m Cable 100A 16mm

Myenergi Current Transformer (CT Clamp) with 5m Cable 100A 16mm

The myenergi Current Transformer (CT100-16-05) is a 100A split-core CT clamp with a 5-metre cable, designed for use with myenergi devices including the eddi energy diverter, zappi EV charger, and harvi wireless sensor. It clamps non-invasively around the grid import/export cable at the meter board, allowing myenergi devices to measure exactly how much energy is being imported from or exported to the grid — without any interruption to the live circuit.

What is a Current Transformer?

A current transformer (CT) is a non-invasive sensor that clips around a live cable and measures the current flowing through it by detecting its magnetic field — no need to cut or interrupt the circuit. The myenergi CT produces a small signal voltage proportional to the current, which the connected myenergi device uses to calculate real-time power flow. This tells the device whether your solar system is importing from or exporting to the grid, enabling intelligent diversion or charging decisions.

Connector myenergi standard CT connector
What's in the Box
  • 1 × 100A split-core CT clamp
  • 5m integrated signal cable
  • myenergi connector fitted
⚡ Installation Note

The CT clamp must be fitted by a qualified electrician. It is clamped around the live grid feed cable at the meter board — typically the tails between the electricity meter and the main consumer unit. The 16mm aperture is sized for standard domestic service cable. If your cable is larger than 16mm cross-section, please check compatibility before ordering. The 5m cable provides sufficient reach for most standard meter board to consumer unit arrangements; for longer distances the optional myenergi harvi wireless sensor transmits CT data without the need for a cable run.

Frequently Asked Questions
Does fitting the CT clamp require turning off the power?
The CT clamp itself can be fitted without cutting the cable, but access to the meter board and working near live conductors must always be performed by a qualified electrician following safe isolation procedures. The split-core design means the CT opens and closes around the cable without breaking the circuit.
Do I need one CT clamp or two?
For a standard single-phase myenergi installation, one CT clamp is typically sufficient — fitted on the live conductor at the grid connection. If your myenergi device needs to monitor generation separately from grid import/export (e.g., for a system without a smart meter), a second CT may be required. Your installer will advise on the correct configuration for your setup.
Can I extend the 5m cable if it isn't long enough?
Extending CT cables is not recommended as it can affect signal accuracy. If the distance between your meter board and myenergi device is greater than 5m, the better solution is the myenergi harvi wireless CT transmitter, which clamps around the cable at the meter board and transmits the reading wirelessly to the myenergi device — eliminating the need for any cable run.
Is a CT clamp already included with the eddi 2.1?
Yes — the eddi 2.1 is supplied with one CT clamp and 5m cable as standard. This product is the replacement or additional CT clamp for situations where the standard included cable isn't long enough, or where additional monitoring points are required in the installation.
