Inverter protection [RE-wrenches]

[John Blittersdorf, Cent. VT Solar & Wind]

Doug,
   I,m not sure of the solution as I have had the same problem trying to tie 
a large wind input into a DC250 with dual inverters.  We really need a 
disconnect box which can hold 3 large breakers , two for the inverters and 1 
for the large source input.  With one inverter it is simple, use the second 
switch for the wind.  Unfortunately when the large sources are used, they are 
often with dual inverters.  I can only recommend a 2nd DC disconnect box for 
the wind and solar inputs but it would complicate metering as you would have 
to have all the grounds routed thru one of the boxes and thru the shunt.   
Anyone else have a better idea?
