All:
The RF Engineers from Solar Edger came out to my home this week to
assess the noise emanating from my neighbors solar panel system.
They plugged into my antennas to view the spectral noise on my receiver
which they then compared to the spectral noise that appeared on their
portable setup near the solar panels. They determined the noise to be
one and the same.
The next course of action is to improve the ground system and install RF
absorbing foam to each optimizer. I also convinced them to replace the
snap-on ferrites located at each optimizer, with larger ones so they can
loop several turns of cable around each core.
They originally said they would just go with the RF foam which is
puzzling: I don't understand how encasing a noisy device with this stuff
could suppress RFI when the device is attached to long runs of cable
that act like antennas. Can anyone explain how that would work?
