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?</span></font><o:p></o:p></p>
