I would be surprised if the PV system has anything to do with this. We’ve experienced strange electrical intermittent problems and they have almost always been related to grounding or neutral problems. I realize that two different electricians have checked out the site, but maybe they missed something like a loose neutral (check all the way back to the service point of connection). It might be worth calling the utility out as well incase their feed has problems.</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext"> </span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">August</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">Luminalt</span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext"> </span></p><div><div style="border:none;border-top:solid #e1e1e1 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext">From:</span></b><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext"> RE-wrenches [mailto:<a href="mailto:re-wrenches-bounces@lists.re-wrenches.org">re-wrenches-bounces@lists.re-wrenches.org</a>] <b>On Behalf Of </b>Hilton Dier III<br><b>Sent:</b> Monday, March 27, 2017 9:04 AM<br><b>To:</b> <a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a><br><b>Subject:</b> [RE-wrenches] Sunpower micros and mysterious outages</span></p></div></div><p class="MsoNormal"> </p><p class="MsoNormal">Friends of mine got a Sunpower system installed last year. Ever since then they have had intermittent problems with circuits in their house going dead.<br><br>The array is 14 each Sunpower SPR E20 327 C AC. The array is mounted on a corrugated steel roof on their garage, about 20 feet from the house.<br><br>What happens is that a circuit in their house will either go dead or brown out so lights barely glow. This happens to various circuits and at any time of day or night. The rest of the circuits will work fine and the event will last an hour or two. The breakers don't trip. They have had two different electricians there to check the house wiring and it's all solid.<br><br>Any ideas? Some kind of metal roof capacitance?<br><br>Many thanks,<br><br>Hilton<br><br></p><pre>-- </pre><pre>Hilton Dier III</pre><pre>Missisquoi River Hydro</pre><pre>Renewable Energy Design</pre><pre>453 East Hill Rd.</pre><pre>Middlesex, VT 05602</pre><pre>Tel: 802-223-6652</pre></div></body></html>
