John,

'Sorry to be dense here.  "Home runs" for each array?  For example, I'm
going to be doing a SB array that's about 200' from the inverter.  The array
is going to be mounted on a barn roof.  The barn will have its own UFER
ground.  Twas my plan to ground the array frames to the barn UFER ground and
run the + and - (adequately sized, of course) to the inverter.  The inverter
will be grounded to the UFER ground at the house.

Am I missing somethin'?

aloha,
marco

- Have to pull home runs for each array.
  (Since we ground our arrays here in the USofA the GFDI circuits see
the other GFDI as a ground fault)
  (In the ROW, with floating arrays you can parallel the arrays and use
Sunny Team for higher efficiency and N+1 redendancy)
