Re: [IRCA] off grid noise

Walt:


The electronics is a small part of the tens of thousands and it causes the interference, not the actual solar array.


As mentioned, some manufacturers are well aware of the problem and claim to be successful at reducing / eliminating it.


https://www.solar-electric.com/reducing-electromagnetic-interference-pv-systems.html is an example.


I'd talk to them an others if I were you.

Noted, Chuck.  You can imagine, though, if after 10s of thousands of $
spent, only to find an increase in noise as a result.  At best, there'd be
no worsening of noise.  Still, 50/50 isn't good enough at my end,but I'm
glad to hear there is hope for low/no noise sources!  I'd like to think of
myself as very green, so one day,....Walt
