Interesting...
What if the array is ground mount? I prefer not to have metallic conduit
underground. Fortunately, for off-grid we often have a combiner on the
rack that qualifies for a disconnecting means.
Also, off-grid Voc is on the order of 100 volts, as opposed to 400 to 600.

William,
It is interesting that the 2008 code also has the "utility-interactive"
typo. None the less, it is appropriate to put photovoltaic circuits in
metal conduit for off grid systems. The risk to fire fighters is nearly
the same in both cases.
