<p>Corey,</p>
<p>Generally, when choosing a larger system with multiple string
inverters, the preferred architecture is to have the string
inverters distributed - located at the ends of each row, and
running AC lines back to a central AC combining location. This
minimizes the length of the high voltage DC wiring to the short
jump from the array to inverter and it allows short circuit/OCP
for the runs back to the AC combiner to be provided by standard AC
rated equipment. This also allows the wire runs to be standard
building wire in plastic conduit.</p>
<p>Did you consider this and choose the "inverter wall" for some
particular reason?</p>
