Derik at HI Power hydro has done several of these with grid tie DC
voltage with diversion.

Hello Wrenches,
Got one for you. . .
We have a customer that has great potential for a micro-hydro system
and already has the grid on his property. The obvious way to tie the
turbine unit in would be to go back through batteries and a GVFX or
XW. In trying to eliminate the batteries and the inefficiencies I
want to look at using a battery-less grid-tie inverter. I am assuming
that I could use a small inverter such as the PVP 1100 and
high-voltage Stream Engine. The problem I am trying to work around is
how to divert the ~240DC output of the turbine, if and when the grid
goes down. Would this be as simple a placing a relay on the AC side
of the inverter and having it switch on/off a large diversion load?
For the diversion load I was thinking I could just series up a set of
water heater elements to get to the necessary voltage.
Has anybody accomplished this before? Jay? Are there any other
elegant solutions for this?
Has anybody successfully used a WindyBoy with hydro?
