David,
Solar systems are digital devices that are classified as unintentional
emitters. If they are marketed into residential environments, they must meet
Part 15 B emissions limits. The only unintentional emitters that require
certification that would create an entry in the database you looked at are
scanning receivers, radar detectors and access BPL devices. Although they CAN
certify if there is no US resident willing to take responsibility under a
Suppliers Declaration of Conformity, the vast majority of unintentional
emitters are not certificated, so there will be no information on the FCC page
containing test data. An SDoC is essentially self-policed. The rules do not
require that test data on devices authorized under an SDoC be provided to the
FCC.
If they are using a certificated WiFi or Zigbee device that is used intact, its
certification would suffice, so there would not be a need for a separate entry
in the database, no more than you would need to certificate your station if you
bought and installed a certificated Bluetooth microphone in it.
Ed, W1RFI

Subject: Re: [RFI] Noise from Generac Solar controllers?
IN further poking around on the FCC OET site under Generac, I can't find a
single report filed on anything except wireless hardware. I could not locate
any complete systems which would include the panels, optimizers, other
electronic switching devices, and simulated house wiring. There is no evidence
in the reports of any test results being filed with the FCC for the entire
system. All the "Max Freq '' frequencies listed on the response pages for a
general search on Generac on the FCC OET pages reflect only above roughly 700
MHz. This tells me they are only filing for the intentional radiator, that
being ZigBee or BlueTooth or some other protocol. No complete *system test* is
filed with FCC. So, how can they claim compliance to even Part 15, Subpart C
(Intentional radiator), Class C (industrial). BTW: Class C systems *do*
require filing a test report with FCC. There is none.
