One of the questions to ask with ACPV is who backs the warranty on the inverter. According to SolarBridge’s website, the module manufacturer warranty’s the combination. This is fine as long as the mfg stays afloat but in this time with such major players as Sharp and BP backing out, who do you turn to if your inverter has a problem? As Bill said Exeltech is in this too, and warranty’s their own, so is one step less removed. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>One of the things we’ve gathered is that Enphase, with an installed base of something over a million, is having some problems with its first version, 190. Is that a problem inherent in the components chosen in its design or something as simple as insufficient potting? It is fairly low percentage, but it also hasn’t been 25 years. And how does that balance with the installed base of any of the other microinverter/ACPV manufacturers? <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>It seems that the temperature at which micros are required to live is the main advantage of remote string inverters. They can be down in the shade with free air moving around them. On the other end of that trend are the ACPV which might have very little room between them and the module backing. There might be several practical actions like mounting the modules with the inverter on the down side so the air flow is cooler (a little like putting the pump or fan on the cool input side of a thermal collector), or spacing the array higher off the roof to allow more air flow.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>I do agree with Bill that this is the direction the industry is heading and very quickly.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Bill Dorsett<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Sunwrights<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Manhattan, KS<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","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";color:windowtext'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma","sans-serif";color:windowtext'> re-wrenches-bounces@lists.re-wrenches.org [mailto:re-wrenches-bounces@lists.re-wrenches.org] <b>On Behalf Of </b>Bill Loesch<br><b>Sent:</b> Tuesday, October 30, 2012 11:43 AM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> Re: [RE-wrenches] AC Modules ready for primetime?<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><p class=MsoNormal><br>Hi Nik,<br><br>As of SPI 2012, Solar Bridge advertized seven module manufacturers using their product.<br><br>Remember Exeltech, manufacturer of exemplary sine wave inverters, is also a player in this ACPV market, undoubtedly other players, too.<br><br>IMHO, ACPV is the route that the industry will _eventually_ follow. <br><br><o:p></o:p></p><pre>Bill Loesch<o:p></o:p></pre><pre>Solar 1 - Saint Louis Solar<o:p></o:p></pre><pre>314 631 1094<o:p></o:p></pre><p class=MsoNormal>On 30-Oct-12 10:13 AM, Nik Ponzio wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal>I have a prospective customer requesting AC modules for a commercial job.
