I recently spoke with an engineer from SolarEdge who said that they
discovered a previously unknown source of RFI which turned out to be the
solar panels themselves. They found that the panels were producing noise
while physically disconnected from the system at a few installations.
They are now working with the panel manufacturers Hanwha and Trina to
determine why a certain batch of their panels are producing RFI. The
goal is to locate installations with the defective panels and replace them.
Cumulative RFI from multiple panels is apparently enough to cause
serious RFI and may be the reason why my neighbors installation still
makes noise during the day while the system is turned off. It could
also be the reason why the choking the Optimizers had little effect.
