There was an extensive discussion here on this exact subject recently.  If I may be so bold, I believe we reached consensus that it is best practice that each inverter have a dedicated disconnecting means for allowing servicing, if for no other reason.

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.
