<div>
<p class="MsoNormal" style="margin:0;padding:0;"><span style="font-family: 'Arial','sans-serif'; font-size: 10pt;">Ok, here's one for you. We have a customer whose utility provider is L.A. Dept. of Water & Power; he's getting ready to install his battery-based grid-tie system with a Radian inverter, load center, HUB4, eight - 250W modules....etc. But the inspector is calling foul, saying his 'battery bank is a parasitic load" <span style="color: blue;"> -- </span><span style="color: black;">the inspector also claims that the battery bank is a “generator”</span><span style="color: navy;"> </span>so he must utilize a straight grid-tie inverter (5KW Power One) and make this an AC coupled system to be legal.<span style="color: blue;"> </span></span></p>
<p class="MsoNormal" style="margin:0;padding:0;"><span style="font-family: 'Arial','sans-serif'; font-size: 10pt;"><span style="color: navy;"> </span></span></p>
<p class="MsoNormal" style="margin:0;padding:0;"><span style="font-family: 'Arial','sans-serif'; color: black; font-size: 10pt;">The question then becomes; does the PowerOne GT5kW inverter play nicely with the Outback Radian when the Radian is the BB Inverter? </span><span style="font-family: 'Arial','sans-serif'; color: blue; font-size: 10pt;"> </span></p>
<p class="MsoNormal" style="margin:0;padding:0;"><span style="font-family: 'Arial','sans-serif'; color: blue; font-size: 10pt;"> </span></p>
<p class="MsoNormal" style="margin:0;padding:0;"><span style="font-family: 'Arial','sans-serif'; color: black; font-size: 10pt;">Maybe there is a way to save our customer the cost of the new PowerOne inverter if we configure the Radian differently?</span><span style="font-family: 'Arial','sans-serif'; color: navy; font-size: 10pt;"> </span><span style="font-family: 'Arial','sans-serif'; color: black; font-size: 10pt;"> </span><span style="font-family: 'Arial','sans-serif'; color: blue; font-size: 10pt;"> </span></p>
