I am hoping to determine the best ferrite core applicability for the purposes of filtering out electrical noise between an electrical combiner panel where AC PV source circuits and microinverter monitor land, and the panel whence the output circuit ties into the grid-tied panel.
An Enphase (microinverters) technical representative suggested the following product:
In particular, I am interested in applicability of similar products given the following considerations:
- Differing voltage or output ampacity characteristics from the output circuit
- Differing physical dimensions of applicable ferrite cores; I am looking at this from an NEC perspective, where a 40% conduit fill factor is not to be exceeded (which would be for the product previously referenced for larger system sizes).
Suggestions and help is greatly appreciated- thank you!
