"Thank you" to all that have commented. Based on inputs, and some independent
thinking, I'm convinced that the exemption results from being part of a
utility. But, I would enjoy a debate on this if anyone sees it differently ?
Of course, this exemption is only for the general technical requirements. The
exempted device is still subject to § 15.5 and § 15.29 , or "thou shalt not
interfere".
thanks again.

Dear Learned Colleagues,
When an application is a utility grade solar PV installation (e.g. solar
"farm", NOT residential installation), would the term "power system" from CFR
47 Part 15 § 15.103 include the switching converters used to convert from DC
to AC grid current?
Here part of the text:
§ 15.103 Exempted devices.
<snip>...
(b) A digital device used exclusively
as an electronic control or power system
utilized by a public utility or in an
industrial plant.
all opinions appreciated!
thank you.
-Patrick
