A fairly good write up of the noise issue with solar
regulators/chargers. There are a couple of things in the article I
disagree with, but for the most part, it's what you'd expect.

I was surprised to see that noise/inerference certification is missing
on a lot of the units.

You really should be able to run stuff in your house directly off the
batteries. Eliminate the inverter completely. Eham dot com has some
inverter reviews.

I'm going to make my ham shack PV/battery, but all the cool stuff runs
on 14 VDC already.

But if the inverter is still charging the batteries in daylight, won't
the RFI still be a potential problem in daylight?

The inverter only creates the Aztec pyramid looking "sine waves" for 117
VAC; batteries are charged through a voltage regulator. There are PV
panels with regulators built-in, which can directly charge 14 VDC batteries.
