I think it is a bit of a blessing to have as the FCC does now...
In addition to actual, real limits, the FCC states in part 15.5:
============CUT from part 15.5==============
(b) Operation of an intentional, unintentional, or incidental radiator
is subject to the conditions that no harmful interference is caused and
that interference must be accepted that may be caused by the operation
of an authorized radio station, by another intentional or unintentional
radiator, by industrial, scientific and medical (ISM) equipment, or by
an incidental radiator.
(c) The operator of a radio frequency device shall be required to cease
operating the device upon notification by a Commission representative
that the device is causing harmful interference. Operation shall not
resume until the condition causing the harmful interference has been
corrected.
(d) Intentional radiators that produce Class B emissions (damped wave)
are prohibited.
============END CUT from part 15.5===========
That pretty well covers everything that interferes with ham radio...

If I am recalling correctly, the Fcc does not include any specifications for radiated emissions below 30 mhz and leave it to "well engineering practice." But that is never defined.

Wondering what they are going to knock down from S9+40 to what, nothing or
something less than?
Also wondering if the FCC is kept informed of this?

Your spectrum plots look just like SolarEdge RFI does.
I just met with a SolarEdge engineer. His contact information is Tefford Reed
<Tefford.Reed@solaredge.com>. They are working on several houses surrounding a ham in Poway, CA
(who has S9 +40dB RFI from the new SolarEdge systems that just went in near him). They plan to correct
the SolarEdge installations near me in two weeks. It is great to finally see some activity from
them. Tefford told me to ask hams with SolarEdge RFI to contact him.

In this case the solar panels could be covered with dark tarps to stop
their interference. They can stay covered until SolarEdge comes out
and fixes that system. Randy KQ6RS
The tarp solution should work. My neighbors SolarEge system goes quiet at night
when the panels are inactive. The attached screenshots show the difference
between the daytime RFI noise level and the nighttime noise level.
