Hi, Did the Solar Edge engineer pronounce the RFI as corrected, or is
this a test?
This was a test Dave. I asked the engineers if they would do the entire
system when they were here in October, but this is the route they chose.
Will keep you posted.

All:
Solar Edge installed RFI suppression on my neighbors solar system on
Monday. They installed 5 clamp-on Ferrites on half the Optimizers
which left the rest of the system open to RFI. Needless to say, this
did little to suppress the noise.
The company will not wrap cables around large cores because they say
that doing so would violate the cables bending radius and could lead
to cracks. I spoke to the engineer today and he maintains that using
several clamp-on Ferrites is the equivalent of wrapping the cable
around a core.
So that's where we are. I should find out the next course of action
this week. I'll keep the group posted.
