Current Transformer Orientation
CTs must be installed with the label (“SOURCE THIS SIDE”) on the CT housing pointing toward the power source (service entrance / grid for Site CTs, solar inverter for Solar CTs). Always verify CTs are in the correct orientation by observing power flow in device setup in Tesla One.

CT Usage | CT Orientation |
---|---|
Solar CTs | CT label facing toward the solar inverter |
Load CTs | CT label facing away from the loads |
