We used to use ferrules on smaller conductors. Both insulated and uninsulated are available. A quick search came up with this source:

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?
