[RFI] Solar Panel Manufacture Schedules Fix For Solar Panel RFI

[Mike NA6MB]

There is a good QST article here:


      APR 2016 -/QST/(PG. 33)

      Can Home Solar Power and Ham Radio Coexist?
      (Feature)

*Author:*Brock-Fisher, Tony, K1KP

He does not name the manufacturer, only the installer.

We have a local ham KQ6RS Randy who has had several of these installed 
in is neighborhood.
Randy is a retired Qualcomm antenna engineer and has lots of experience 
and test gear to find and characterize the interference.
The company (manufacturer of the system) causing most interference 
locally is Solar Edge (SE).
Several local installers have installed noisy SE systems.
Randy has given several talks about his problem and solutions.
He has worked with SE to explain why it is interfering.

There is a new system about to be released "soon".
That does not solve the currently installed systems nor the systems 
installers have in stock ready to install.

The problem, as stated in the article, is that they use boosters on each 
panel and configure the wiring in a loop.

The company has been cooperative by directing the installers to install 
toroids and change the wiring to NOT make a loop.
This helps a great deal.
For some reason (expense I suppose) they don't want to change the 
recommended installation method.
They have fixed several locally but have recently complained about Randy 
giving his talk and "drumming up complaints".

ARRL RFI office has also helped.
