[RE-wrenches] Question re fine stranded cable with Sunny Islandinverters

[John Berdner]

Alan:

Use a ferrule on the inverter end of the wire.
Makes fine strand cable suitable for "normal lugs"

Burndy has some that they say are for fine strand (Class K) cable.

They look exactly the same as the cheaper un-insulated ferrules from ferrules direct.

Subject: [RE-wrenches] Question re fine stranded cable with Sunny Island inverters

Wrenches,
A small issue, drawing on the collective wisdom here:

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? Are there any other suggestions that will allow us to use the 1/0 X-Flex?
Thank you,
Allan
