      Do the subpanels that hold the Solar breaker only hold the solar breaker, or do they also hold regular load breakers?

      Because if they do then you cannot monitor these subpanel through their feeding breaker, because the power will eventually go in both direction there, and right now, the 50A CTs do not report bidirectional power. In the future they will, but right now they don’t.

      So if a 50ACT is on a breaker designated as load and installed in the load direction, they will always record the power as + regardless of direction, and 50ACTs on a breaker designated as Solar (installed in reverse) will always report load as minus regardless of direction

      Okay, I see now…   Yes, these breakers that feed the sub-panels DO indeed support load within these “uplink” breakers (i.e. not just solar).

      So for clarification (and to help me fully understand), what would be the outcome if these breakers WERE dedicated solely to solar inverters?  I assume from your description, that this would be the way in which it would indeed work?  Is this right?  If so, is there ANY way to make this happen in the meantime (while waiting for bi-directional 50A CT’s).

      Thank you VERY much!

      If you put a 50ACT on a solar only line, then you just mount it in opposite direction, and declare it as such during the setup.

      Then its power will be recorded as production and not consumption.

      You do need to make sure the Solar breaker the CT is mounted on is OFF when you do the setup, and that you only turn it on when instructed.
