OK, is that the AC breaker or the PV input breaker ?
How about when you throw the PV input breaker (when not MPPTing) ? Does
that help ?
i.e. We know now that it's the inverter's auxiliary power supply, but
is the signal also getting
out (radiating) through the PV lines ? It could also come out the PV
negative so throwing just the PV input
positive breaker, by itself, may not tell the whole story.
If it's coming through the AC line, then a line filter, or running all
of the AC side wires through
a ferrite toroid may help.

Does the radio noise go away when you completely disconnect the SMA
inverter ?
