If you read above and elsewhere in the Community you’ll see that some of us are using the Solar (& Main for that matter) CTs for individual devices.
FYI: You can use an individual CT for a single 120V device.
My irrational theory is Sense may eventually allow some kind of modal switch for Mains/Solar so a “subSense” can be used for dedicated circuits of devices. Potentially even 4 x 120V.
