Re: [RFI] Anyone tested Solyndra panels for RFI?

[Michael Carter <Mike.Carter@unh.edu>]

Hi David,

The Solyndra panels generate DC and have no attached
microinverters/optimizers.  They are not in themselves
RF noise generators.  Others may wish to comment
on the virtues of different charge controllers, which invariably
use switch-mode power conversion.

Mike, K8CN

Yes, really ...

The panels from the 1/2 billion dollar government fail, and

3/4 billion investor fail, have been showing up on the market

for a couple of years.

I just saw them here:

I have a shallow sloped metal roof (white) that would be perfect,

but not if those 100v tubes are noisy!

Also, is Morningstar still the go-to for quality and RF quiet charge

controllers for a 95v panel (125v peak) into a 48v battery system?

Must protect the noise floor!

Thanks, David, KD4E
