[RE-wrenches] Two Buildings, Two Services, One Roof

Thanks Nick,
 
250 talks about two seperate buildings with one service, and 230 talks about
one building with two services.
 
I don't think this particular situation has been contempated by the Code.
 
How big a deal would it be to just bond the two ground electrode systems
together and go along my merry way?

It seems like it should be fine if you run one conduit to your shop
inverter, and another to a dc disconnect and underground to the house
inverter, but I see you running a bonding wire for the 2 GECs as well for
some reason. You should go through the part of 250 about different GEC for
separate building, which has some optional installation options, and you
could likely use that to justify running the equipment ground back to the
house.
