<div>Marco- You should not transition to THHN wire at all for
the DC run. The PV wire is double insulated for a good reason-
the transformerless inverters are such suckers for a ground
fault that they need the extra protection. That's why the NEC
specifies PV wire. </div>
<div>I recently did an installation like you wrote, with a
transition at the j-box. This developed an intermittent ground
fault when wet, and when the P1 inverter failed it was deemed
out of warranty. Learn from my mistake-- use PV wire all the
way to the inverter. </div>
<div><br>
</div>
<div>That said, does anyone know where to get 1000 volt PV wire
in colors other than red, black, and white?</div>
<div>It would be nice to color code the positive runs like is
possible with colors of THHN.</div>
<div>I'm thinking of buying spools of white and spraying plastic
paint on them for a striped color coding.<br>

Hi all,<br>
<br>
We're doing more and more installs with TL inverters (SMA
and P1).<br>
<br>
I'm using double-insulated wire from the array string to the
first<br>
enclosure, as in j-box, and then transitioning to standard
THHN/THWN wire.<br>
<br>
