For an upcoming quad-stack installation of
Sunny Island inverters, I foolishly ordered some fine stranded
copper 1/0 Cobra X-Flex Cable because of its flexibility. In
this situation, because of NEC ampacity requirements on our
total DC cabling (this system also has a single Radian for
some dedicated loads) we are only running 125 amp DC breakers
on each SI inverter. Our issue is that the SI installation
manual specifically notes not to use fine stranded cable into
the terminal lugs. This was news to me. We can purchase 1/0
Ilsco or Panduit copper pigtail adapters to make the
connection into the terminals of the inverters, but they are
$10 to $14 each, and we need eight of them. Is using doubled up #4 or #2 the only
solution? Thank you, Allan Sindelar
