<div dir="ltr"><div><div>Carl,<br><br></div>We experienced a rash of Comm Card issues with several SE installs over several years, but none exactly as you describe. Our issues were almost all resolved with a board replacement, but a few were particularly vexing with many return service calls to get a resolution. We seemed to have the most problems with the single phase 10k inverters. In general, SE tech support was helpful, although a bit paint-by-numbers at times, as well as very slow to answer for much of 2015. As best I can tell, the issues have begun to settle down most recently.<br></div>Howie<br></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><span style="color:rgb(120,63,4)"><b>Howie Michaelson</b></span><br><font size="1"><i>NABCEP Certified Solar PV Installer™</i></font><br><span style="color:rgb(106,168,79)"></span>Sun Catcher, LLC<br><span style="color:rgb(68,68,68)"><span style="background-color:rgb(255,255,255)"><font size="2">Renewable Energy Systems Sales and Service<br>VT Solar Electric Incentive Partner</font><span></span></span></span><br><span style="color:rgb(180,95,6)">802-272-0004</span></div></div></div>

We have some systems installed in 2012 exhibiting similar behaviors. The systems are producing data, it is registering on the inverter, and our independent utilty meter, but is not reported to the SolarEdge portal. Next day(s) it reports production to the portal but the missing data is never filled in. I have attached a small graph from the portal dashboard.</div><div><br></div><div>Typically if a network connection goes down, and then is restored the data should be uploaded after the connection is back on line. In this case their remains a hole in the data, for that day, indicating that data was never uploaded.</div><div><br></div><div>We had one system which exhibited this "missing data" symptom on accasion over a 2 month period of time. This was diagnosed, as a failing comm card. Once that was replaced we have not seen the issue recur for that site. But now we are seeing similar behavior from three other sites, all installed a in the second half of 2012. </div><div><br></div><div>Just wondering if anyone else has encountered this.</div><div><br></div><div>Thanks</div><div>Carl Adams</div><div>SunRock Solar</div></div><div><br>
