			Overall design:
			* Loose the batteries and the charge controller, simpler system with just an inverter, grid disconnect, and bi-directional meter and base.
			* Slightly larger turbine, say 1-1.5 kW.

			Design changes:
			* Larger conduit, 4", from tower to the side of the house/utility interconnect.
			* Conduit path will be re-marked to avoid existing buried cables with one turn.
			* 48V?, recalculate conductor size, do we need to use #3?
			* When we pull the conductors we should also pull shielded twisted pair for data.
			* Large enough enclosure to also accommodate a charge controller if we decide to add one later.
