Nick,
I think the best alternative would be to use four turbines; each set of
batteries is maintained with its own diversion control.
To use just one turbine, put a single diversion controller at the
turbine and set it to keep the voltage below 16 volts (plus the largest
voltage drop possible in the system). Then use a separate series-type
voltage controller (such as a Morningstar TS-45) at each set of
batteries. Problem with this scheme is that the lowest set of batteries
hogs all the power. It'll be really hard to get anyone's batteries
equalized. One energy piggy in the group will make sharing a nightmare.

Esteemed fellow wrenches: May we put our heads together on today's
problem
in my terrain: How best to distribute and regulate the output of a single
turbine from a convenient distribution point to
four residences on the off grid property, each with it's own 12 volt
battery/inverter system. If I may spare you the details of the
lake/stream/intake/penstock and apparatus, let's say we have
sufficient head and flow to divide 700 watts four ways, average distance
maybe 300 feet. The problem becomes: diversion controllers and dump
loads
at each battery or some central scheme?
Anybody done this kind of thing? Cautionary tales welcomed. (Any
experienced comments welcomed.
Thanks muchly in advance. Nick Houser Off Grid Services, Lund, British
