Thanks for that G2 Bob. My current local installs are years old but that beam can hear one on the next ridge over.

The Solar Inverters that are terrible are the OPTIMIZERS. Little RF
generators on EVERY panel all over the roof.
I have received reports that Microinverters are OK, and that String
Inverters are OK. But the string inverters are the easiest to suppress
further because they only have DC on the roof and are easiest to add any
torroids on the two DC wires down at the inverter.
All of the reports I have collected so far are in the ARRL "Energy Choices
for the Radio Amateur" book coming out in April.
But this will not just be your own system problem. If your neighbor goes
solar with the OPTIMIZERS, you are screwed. Get out there and talk to
your negighbors NOW... Don't be surprised...

I think I have heard somewhere that solar panel inverters can be horribly
noisy. I think that maybe I heard that the micro inverters are the worst.
Does anyone have experience? What bands are worst hit? Any particular
inverter brand/type good or bad? How far from the inverter is your
shack/antenna?
Thanks and 73,
