Here was the Solar Edge response I found in an Aug 2022 PV Magazine article:
"“SolarEdge and Ampt have been litigating a dispute involving a patent family
filed by SolarEdge and a patent family filed by Ampt before the US Patent and
Trademark Office (USPTO) for many years,” SolarEdge told pv magazine.
“Recently, the USPTO awarded priority of invention to SolarEdge, canceled the
claims of Ampt’s patents, and awarded the patent claims in these Ampt patents
to SolarEdge. It appears that having lost before the USPTO, Ampt is now
shopping around its claims to other courts. SolarEdge anticipates a vigorous
defense of these new cases.”
If this statement is true, I don't think that the issue on ethics is fully
represented by the claims of the attorney filing the class-action suit. We see
those claims all the time in various advertisements. Patent claims happen all
the time and many are due to the US Patent Office not thoroughly checking
patent applications.
Having said that, Solar Edge has been more responsive than most manufacturers
regarding interference complaints. There have indeed been a few problems that
seemed to get derailed, but the majority of the reported cases have been
resolved.

BTW
Have you seen this? A bit of a peek into SolarEdge's ethics.
