The generator, when started with the SI, would run for a few minutes and then shut down. Further investigation revealed that the SIs were indicating that the inverters were sending lots of power back to the generator. I don’t know if this was actually the case, nor can I grasp how this could happen. Fortunately I reached an off-grid tech at SMA that I trust (among the many at SMA I do not, please don’t share this email…) and we were able to resolve the issue. I am not sure what we did but I suspect that simply rebooting the Sunny Islands was the cure.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:#1F497D'>We did little to evaluate the batteries. They did seem to hold rock solid under loads. I am not convinced, however, that these batteries are right for off-grid. The internal battery management system will allow them to disconnect under surge loads, just when you need your batteries to stay connected. I will be conversing with the manufacturer to learn more about them.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:#1F497D'>William<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Arial","sans-serif";color:black'><img border=0 width=64 height=28 id="Picture_x0020_1" src="cid:image002.jpg@01CFD2BC.7AE05300" alt="Gradient Cap_mini"><br>Lic 773985<br><a href="http://www.millersolar.com/"><span style='color:blue'>millersolar.com</span></a><br>805-438-5600<o:p></o:p></span></p></div><p class=MsoNormal><span style='font-family:"Arial","sans-serif";color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif"'> RE-wrenches [mailto:re-wrenches-bounces@lists.re-wrenches.org] <b>On Behalf Of </b>Starlight Solar Power Systems<br><b>Sent:</b> Wednesday, September 17, 2014 4:06 PM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> Re: [RE-wrenches] LiFePo4<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>William,<o:p></o:p></p><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal>What did you find at the site?
