[RE-wrenches] wire management on Qcell AC module

[Dave Tedeyan]

Hi all,
I realize it has been a while, but I've been meaning to send out an update.
With these modules in particular, one lead was long enough to get a clip on
the side frame. We found that if we put the upper rail as low as possible
allowed by the module (about 19.75" from the top) then it roughly split the
distance from the junction box to the microinverter. It seems that even
over time, there is not enough slack with the rail there for the wire to
ever reach the roof. It is possible that it will eventually sag such that
the wire is visible under the rails, but at least for now, you cannot see
any wires under the array.

Cheers,
Dave
