Bill, typically inverters have a max OCPD that can be installed on their
output, and these sizes are generally not large enough to accommodate
two same-model inverters. And manuals often note that you need to have a
dedicated OCPD anyway. At least if I were ever to double-up two
inverters on a single breaker, I'd want to make sure I had clearance
from the manufacturer to do so. Or... just buy the $75 box to combine
the two.

Wrenches,
...its the little things. Recently someone here brought up
the issue of combining AC outputs prior to backfeeding the "solar" CB
in the mains panel. In the past I've run AC outs from inverters into
a small AC dist panel, backfeeding CBs and then ran my combined AC out
from a larger CB or the busses themselves to the backfed CB in the
mains panel. Is this overkill?
It does seem as though, at least for just 2 inverters, this
could be done with just split bolts in a gutter or dedicated
J-box....or a power distribution block?? Or...?? (no wire nuts, thank
you) Your ideas appreciated.
