Solar knockout notch!
Pro-Q3 has a notch that goes to 96dB/oct and can go up to (and above) 20kHz.... not what you need? :)

If anyone can make this, and affordably, FabFilter can: a very sharp and deep notch, 40dB at least, to delete intrusive 20 kHz electrical whistle from a solar panel inverter. Gets in everywhere, chiefly via mains wiring, but some is even acoustic. Low-pass tried, but not steep enough: takes out too much 15kHz on the way.
Likely to be an increasing issue for audio people as panels are installed more widely and with limited awareness. Bah!
