[amsat-bb] Solar panel inverters--radio noise?

[Mike Lussier]

Greg,
My system is two SMA inverters with 48 panels combined between them. I can
only say that my system has never caused any noise issues. My panels are
pole mounted in the far end of a field to optimize the sun. Each pole has a
dual axis tracker that are powered by a 5th pole with stationary panels
looking south to power the trackers.

The SMA inverters are back at the house in my shack. There are about 17
ground rods between the 4 poles supporting the arrays, The house, towers
and sub panel boxes. All of those ground rods are all interconnected.  When
the power company came out to certify the system they megs the system and
told me that the grounding  that I had in place was way better than any sub
station.

I take it that proper grounding is a big plus.

Mike
