Who is manufacturing the racking? DPW has worked with us to develop
some screening options. WE have also developed our own screening
(and wire management) procedures. We spend a lot of time creating
these procedures we keep them to ourselves to prevent local competitors
from stealing appropriating ideas. I can give you more ideas off
list.<br><br>
I think we all need to be calling racking manufacturers and requesting
they develop screening and wire management options for their
products.<br><br>

<blockquote type=cite class=cite cite>Hello Wrenches,<br><br>
We are installing a ground mount system with Enphase inverters.
690.31 requires readily accessible source and output conductors OPERATING
at over 30 volts to be installed in a raceway. The Vmp of the
REC230PE modules is 29.4 volts. Of course it would go higher in
cold weather. Do I have any argument that would allow us to not
install the DC conductors in a raceway?<br><br>
The NEC Handbook comments "Most PV modules do not have provisions
for attaching raceways. These circuits may have to be made "not
readily accessible" by use of physical barriers such as wire
screening".<br><br>
I have heard of a green screening material that has been used on the E, W
and N sides of ground mounts to render the area not readily
accessible. Does anyone know what this is? What else would
work that would be more cost effective than running a chain link fence
around the array?<br><br>
Thanks,<br><br>
