Mark,
PowerSpout, from New Zealand, (www.powerspout.com) makes a grid tie
version of their turbine that includes a dump load water heater at
the inverter and uses an SMA grid tie inverter. Worth checking into.
Good luck,

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?
