[RFI] solarever - recommend quiet mmpt & inverter?

[David Colburn]

We're looking at 10 or 20 of these panels here in SE-GA:

I've been planning a 48V battery rack but am told that 56V may be even 
better for

efficiency when converting to 120vac.

Can anyone recommend a MMPT Controller & and Inverter (perhaps a combo) 
that's RF-quiet?

Thanks,
