At least when we sold these they were not listed. We got caught on this a
couple of times in WA state and were not allowed to install them. Also Grundfos
said not to use a Gfi with them. Maybe a dc gfi might be ok on the PV side of
the CU200.

If it is all Grundfos electronics and the panels they specify, then I
would get a permit and let the inspector make the decision.

Well Jay, if you call each of those poles "arrays" then you've got a path
around the 2 parallel circuit maximum :)
Note 2020 NEC language has changed a bit, though it's still not crystal
clear:
"PV system dc circuits that exceed 30 volts or 8 amperes shall be provided
with dc ground-fault
HI All,
I’ve got a question about GFDI requirements and do they apply to the following.
Here is the project.
1. water pumping DC direct grundfos SQFLex
2. no humans anywhere around
3. no buildings or living structures
4. would be 3 pole mounts: each mount as 1 string, so 3 strings.
