Bruce & Matt,
I've started installing additional fuses in the cables, on the positive
end, that connect the strings together. That way if one of the strings
has a shorted cell, the other strings will only be able to dump power
into the weak string until the fuse (or fuses) blow.
I prefer one string myself, and I won't parallel more than 3 strings but
IMO sometimes it's nearly impossible to size the battery bank adequately
with just one string.
Good thread,
Greg
