style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">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?<o:p></o:p></SPAN></FONT></P>
<P class=MsoNormal><FONT face=Arial color=navy size=2><SPAN
style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">For the diversion
load I was thinking I could just series up a set of water heater elements to
get to the necessary voltage.<o:p></o:p></SPAN></FONT></P>
