[RFI] Question Regarding Variations In Solar Panel RFI?

[Tony]

All:

The reports I've read suggest that the strength of interference caused 
by solar panel systems can vary from one installation to the next EVEN 
when the distance to the source is similar. That variation could be 
attributed to radiating conductors tied to the system such as the house 
wiring.

We found high levels of RFI on the A/C lines throughout my neighbors 
home and that's likely the case with all Solar Edge installations since 
there are no chokes between the mains and inverter.

Given those facts, would a large home with long runs of un-shielded 
Romex produce higher levels of interference compared to a smaller home 
with shorter runs? Or does the resonance of the wiring play more of a 
role than length and number of runs?

It's an oversimplification, but it seems logical to consider what's 
connected to system and not just the system itself.
