Has a company come up with a AFCI DC breaker yet? I have seen quite a lot of blogs on the NEC 2011 but by now I would think it would be resolved. I am in need of a 15A breaker @ 272.5 VDC (probably need something like 400 VDC). Any insight is appreciated!

    Where are you planning to put this breaker?  Midnite solar sells an arc fault combiner box.  (last I heard, they sent it off for UL certification... not sure if it's actually shipping yet)
