Thanks David.

One other related aspect of this install, is where I'll run the cable
from panel to controller. I'm using this:

template.  The holes in the poptop appear to be sized for the OD of
the cable itself, not the MC4, so had to wonder if that person
disconnected the cables from the junction and ran them back up etc.

The cable attached to the panel is more flexible than the supplied
flat #10/2 cable. ('twas a kit) OTOH, I don't think there's any great
danger that repeated up/down of poptop will cause the wire strands in
the flat cable to fail any time soon.

Neil.
