I have a string, no HF RFI.  If I go right next to the inverter with a 2
meter HT I get some RFI......5 feet or so from the inverter.

With the micro-inverters you have numerous inverters that can cause RFI, and
there is a good likelyhood they may be closer to your shack than a single
inverter.

My inverter is a SMA brand.

The question was about RFI. What do you know about that?
