I've got to ask: Are none of the lugs on these Chinese inverters
approved for fine strand cable? I just have not had a problem with
that, but I've mostly used Magnum, Midnite, and Outback equipment over
the years. What were the lugs on the old Trace DC 250 boxes? Were
they fine strand rated? They sure were tough to get 4/0 into, as
William mentioned.

William,
If the only reason the ferrule wouldn't fit after using the hex
crimper was the ridge left where the dies meet, you could rotate the
cable 120 degrees and crimp the ferrule again.
I doubt that the indenter crimper will do a decent job with large
ferrules.
I do like your thin piece of copper solution. Not UL approved but I
dare say wrench approved.

Friends:
Thank you for all of your input on this question. I feel it only
right I report back how this turned out
I tried a crimper like this:
It left a jagged ridge on both sides of the ferrule where the dies met.
The crimper below was suggested but I have not tried it:
This was suggested but I have not tried it either:
