<div dir="ltr">Friends - are you installing surge arrestors on your PV input conductors and grid side AC conductors to hopefully prevent some of the surge and lightning related damages to inverters? We use SolarEdge often and have other issues which frustrate us but not often surge related issues. We usually will install Midnite MNSPD devices on either side of inverter (DC and AC) and surge related issues have been very minimal to non-existent. I know many of you are in areas with much higher incidences of lightning and grid tribulations than our area. It does add more expense to the systems up front but, hopefully it saves significantly more expense and frustration down the line. <div>Yes no doubt SolarEdge has a LOT of room for customer service improvement yet, some of the benefits of their MLPE even when installed on a roof can be really helpful and save a lot of time troubleshooting that a string inverter can't ever offer. And yes it is very nice to work on equipment that isn't hot until you choose to make it so. </div><div>Enjoy the weekend!</div><div><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr" style="font-size:12.8px">Sunny Regards,<br>Kirpal Khalsa</div><div dir="ltr" style="font-size:12.8px">Oregon LRT<br>Oregon Solarworks LLC<br><a href="http://www.oregonsolarworks.com/" target="_blank">www.oregonsolarworks.com</a><br></div><div style="font-size:small"><span style="font-size:12.8px">541-299-0402</span><br></div></div></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, May 24, 2024 at 1:39 PM Scot Arey 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="msg-932877714867029796"><div lang="EN-US" style="overflow-wrap: break-word;"><div class="m_-932877714867029796WordSection1"><p class="MsoNormal"><span style="font-size:11pt;font-family:Calibri,sans-serif">This wasn’t an RSD rant (and thank gosh NEC2023 clarifies and reduces some silly RSD requirements), but a rant over the damn finick-iness of the BUI and multi-inverter setups from SE. <br><br><u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11pt;font-family:Calibri,sans-serif">I’ve developed a nervous tik that comes on with lighting and storms and hits a peak when phone rings from customer immediately after the storm…heck, even the surge from the grid utility coming back seemed to freak out the one I was at yesterday which was operating fine in backup mode.<br><br>Can’t say many didn’t say, “I told you so.”<br><br>Enjoy your weekends.
