[RE-wrenches] 10 stack outback

If you use multiple FW-1000s and the FN-DC to tie all three shunts
together, you can wire the entire inverter side with 3' cable sets.
Greatly simplifies your wiring, and ensures each inverter sees similar
voltage drop.

Probably want to consider running the FWs horizontal, to act as one big
"gutter" otherwise the top inverters need ladders to access ;-).  I
suggest three FW-1000s instead of 2+1 FW-500, as you probably will want
to add some charge controllers, which are easiest to mount on the open
FW-MP backplate (OB's charge controller brackets don't work when the FWs
are sideways.  Argh).

The AC end is simple -- just input and output breakers.  If you want to
add bypass capability (a good idea) that has to be done external to the
OB equipment when you go beyond 8 inverters.  

If you want a itemized parts list, contact me off-list and I'll work
something up.

HI All,

Does anyone have a parts list and wire lengths for a 10 stack outback  
system?
this is the vertical 10 in a row, not 21/2 quad stacks.

I can do it but thought someone else must have all this done before,

many thanks,

jay
