<p class=MsoNormal style='margin-left:.5in'>Wrenches, <o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'><o:p> </o:p></p>
<p class=MsoNormal style='margin-left:.5in'>We recently installed a grid-tie
battery backup system using two Outback GVFX 3648 inverters. The client
has an existing Generac backup generator, 8 kW @ 240VAC. From the
beginning we told the client that the power quality from the Generac may not be
within tolerance to integrate with the grid-tie inverters and charge
batteries. This assumption was confirmed today when we commissioned and
tested the system. The output frequency of the Generac was 58 hz.<o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'><o:p> </o:p></p>
<p class=MsoNormal style='margin-left:.5in'>To get to the point does anyone
have a battery charger they recommend for this application?—8 kW @ 240VAC
generator output to 48VDC battery bank. Or maybe another suggestion to be
able to integrate the generator into the system, we are also planning on
manually transferring the generator output to power the critical loads if an
inverter goes down.<o:p></o:p></p>
<p class=MsoNormal style='margin-left:.5in'><o:p> </o:p></p>
<p class=MsoNormal style='margin-left:.5in'>It also seems that the dc genset
controls through the mate would be the best way to control the battery
charger—any thoughts?<o:p></o:p></p>
