The generator power should pass straight through the SW inverter, and 
on down the hill.

Maybe you need to run power back up the hill from the solar system to 
the wind system under certain conditions.  If you had a 3 core cable 
you could use it for power in either direction.

Starting from scratch I would try to site the wind and solar and 
batteries all together and run all the loads from one system.
