Kent:
In a normally grounded array, the grounded conductor is the negative conductor, right? So, no disconnecting the negative conductor. It should go straight through the DC disconnect and on to the inverter. Correct? Bob Clark SolarWind Energy Systems, LLC P.O.

See 690.13. There must be a means to disconnect all conductors of a PV system. If it is a normally grounded array you are not allowed to put a switch in the grounded conductor, except .... for circumstances added in the 2011 code.
