Typical install.
The picture on the right is from Lance Barker.
It shows an MNPV6 with a MidNite Solar DC-GFP installed inside along
with two combiner breakers.
This is a novel use of the DC-GFP in the combiner enclosure. The use of
din rail mount breakers makes
for real flexibility. 18” trenching is reduced to 12” when
a DC-GFP is on the PV end of the trench. 2008 NEC article 300- wiring
methods 300.5 page 70-129 , table 300.5 minimum cover
requirements, 0 to 600 volts, burial in millimeters (inches) column 4:
residential branch circuits rated 120 volts or less with GFCI protection
and maximum over-current protection of 20 amps or less. Lance’s inspector used the working voltage rather
than max voltage in his determination. Lance was digging in a rocky area, so this trick made the job possible.
You would not be allowed to reduce the trench depth if using a 200 or 250 volt controller and PV array.
