They love this excuse. They seriously need to train reps that this is not a catch-all conclusion. I'm happy you finally got it resolved, but the noise rabbit hole is an annoyingly pervasive pathway for Enphase customer service reps.</div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif"><br></div><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">Once I have a resolution, what I usually do is ask them to provide a detailed technical email that explains the problem and resolution. Tell them your customer wants an explanation of why the issue occurred. That can sometimes provide some insight into what happened. Also, don't forget to check the "System Dashboard" in Enlighten Manager. The logs can sometimes provide at least some useful information.</div><br clear="all"></div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><br>Jason Szumlanski<div><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">Principal Solar Designer | Florida Solar Design Group</span><br style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px"><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">NABCEP Certified Solar Professional (PVIP)</span><br style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px"><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">Florida State Certified Solar Contractor CVC56956</span></div><div><font color="#333333" face="Roboto, RobotoDraft, Helvetica, Arial, sans-serif">Florida Certified Electrical Contractor EC13013208</font></div></div></div></div><br></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Tue, Sep 2, 2025 at 11:48 PM William Miller via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg8607909174375951904"><div lang="EN-US"><div class="m_8607909174375951904WordSection1"><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">Friends:</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">I have a project where I installed 36 IQ7 inverters a few years ago and then another 12 on a different building about 2 years ago</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">On June 6 of this year a few of the 12 micro-inverters stopped producing.

I tried again today and the tech was able to determine there was a setting that when changed allowed communications. He also said there was a low DC resistance that indicates an arc fault. He was able to correct both issues and the 12 are now communicating and producing.</span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif""> </span></p><p class="MsoNormal"><span style="font-size:12pt;font-family:Verdana,"sans-serif"">The problem is over so I don’t want to put a lot of thought into this but my curiosity won’t let me stop thinking about this issue.
