[RE-wrenches] Three-phase off-grid

[Gary Willett]

Allan:

Also, you might consider using six to nine Schneider/Xantrex XW6048 
inverters, or six to nine Outback Radian GS8048 inverters, in a 3-phase 
configuration, with a common battery bank.

Also, Schneider/Xantrex has an 80A 600V charge controller that may be 
advantageous depending on the distance from the PV arrays to the inverters.
