ShadowCatcher - The INVERTERS generator all of their noise on the 120VAC line leaving the inverters. They actually act like antennas. I moved one of my inverters to a long distance point 150 feet away and hooked up to a separate DC source. I measured RFI all along the extension cord just like it was an antenna. The RFI fixes needs to be proper filtering around the 120VAC receptacles. A center tapped xfmr works the best for getting these signals to ground on the primary side of the xfmr using caps etc...
The DC side of things usually some well located capacitors and ferrite beads. You can always wrap the DC cable loops in and around ferrite device usually does the trick as well.
CAMPERPAUL on here had very good success in soldering in some surface mount capacitors around the center pin and outer ring of connector plugs to help eliminate RFI from some of his LED lights adapters. Pretty small caps for me to be messing with my fat fingers haha..

I'm sure you could fix all of the RFI sources if you put enough time into it...
I just turn off my INVERTERS when I am net control and need real quiet frequencies to use. All of my radios are 12VDC anyway.
I am very new to the solar techniques but it does seem if you used the 90-120 voltages you might have a better chance converting down to the 12VDC voltages you need to use to re-charge your batteries. The only way I know that works well for me is to mimic the converter/charger smart mode charging operations... That would be my primary mode coming from the solar panels. (14.4VDC-13.6VDC-13.2VDC)
