Connecting the CT Coil
The CT coil is one of the most important parts of the Sunsynk inverter. This device reduces the power of the
inverter to prevent feeding power to the grid. This feature is also known as “Zero Export”.
1. Fit the coil (sensor) around the live cable on the main fuse feeding the building and run the cable back to
the inverter. If using an external meter, you can extend the cable for more than 10 metres. Plese consult
the meter manual on distance.
2. Connect the other end of the CT coil to the inverter terminals.
NOTE:
When the reading of the load power on the LCD is not correct, please reverse the CT arrow.
When the inverter is in the o-grid state, the N line needs to be connected to the earth.
