Christopher,
I can’t be certain, but I suspect that the APSmart units have the same
circuitry as the Tigo RSD units. I say that because of the press release
below. I suspect that the only difference is the enclosure, but that is merely
speculation. Interestingly, I worked for Tigo nearly a decade ago. Way back
then they had just developed the “PV Safe” button, which if I recall was
essentially just a software feature. I remember giving a seminar with Brooks
in audience - he was very intrigued and said that this side feature was
probably more important than any of the other whiz bang stuff that we were
trying to promote. I think this was right around the time when RSD was first
being discussed. The irony is stinging me now that I was, and I must admit
still am, a proponent of finding some way to safely de-energize panels/arrays
(just not with a piece of plastic junk). I like what Einstein said
”Information is not knowledge. The only source of knowledge is experience. You
need experience to gain wisdom.”
APsystems Withdraws IPR Cases With Patent Office Against Tigo Energy and Signs
License Agreement
April 28, 2021 01:51 PM Eastern Daylight Time
SEATTLE--(BUSINESS WIRE)--APsystems has announced that the company has
withdrawn its IPR cases with the patent office against Tigo Energy following
the joint settlement reached by both APsystems and Tigo Energy in the IP
dispute.
While APsystems denies any kind of infringement and complies with Sunspec RSD
requirements, to avoid the expenses and inconvenience of litigation, APsystems
has agreed on the settlement with Tigo under which APsystems obtains a license
to use Tigo’s rapid shutdown technology. The licensed technology is the same as
the 6 patents that Tigo disclosed to Sunspec in 2017.
APsystems will continue to deliver leading edge RSD solutions to its customers.
Terms of the license agreement are not disclosed and include APsystems legal
entities in the US as well as in China.

Is this the same concept as Tigo? (and others)
