Sorry, I don’t think there is a way to connect CTs when there is a busbar between meter and panel.
essentially no wires to measure incoming current from Grid. Do you/will you have Permission to send power back to the Grid?

@powerup I currently have a grid tie inverter, so yes I can sell power back. I have used emporias ct's in the past on the busbar connection
They are a bit tricky to install but they work, and
they require external power. They may also work in the case, but they do not have a rj45 connection and I don't have the specs

@swiftsail Thank you, can you describe the integration?
Did you make your own RJ45 connection? Did you need to adjust Inverter settings for this to function?
Thank you,

@nathanael47 I did not receive any details on how to get R-Coils to integrate with EG4. My impression is that the implementation is CT's. The site I needed it for has PTO for sell-back, so we are just operating the unit based on Time-Of-Day and not offsetting actual utilization.
