style="font-size: 10pt; font-family: Arial; color: navy;">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 color="navy" face="Arial" size="2"><span
style="font-size: 10pt; font-family: Arial; color: navy;">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>
