You could also sleeve a direct-burial cable into the ground. Calculate the voltage drop over the distance to make sure 10AWG is adequate. If not, then make a junction, like a MidNite or Outback combiner or an IMO switch at the array to get up the right wire size, with an added MidNite Surge Protector or EMP shield device. If it\u2019s a long distance (larger wire size), add another combiner at the inverter building entrance to get back to 10 AWG. </div><div><br></div><div><a href="https://practicalpreppers.com/product/imo-4-pole-16-amp-dc-disconnect/">https://practicalpreppers.com/product/imo-4-pole-16-amp-dc-disconnect/</a></div><div><br></div><div>Also, The Sol-Ark sizing guide helps with string calculations. </div><div><br></div><div><a href="https://www.sol-ark.com/solar-panel-sizing/SolarPanelSizing.html">https://www.sol-ark.com/solar-panel-sizing/SolarPanelSizing.html</a></div><div><br></div><div>Contact me off list with additional questions. </div><div><br></div><div><br><br><div dir="ltr"><div class="" style="caret-color: rgb(0, 0, 0); color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; -webkit-text-size-adjust: auto;"><div class="ApplePlainTextBody">Maverick Brown<br>Off-Grid Solar Commander since 2006<br><b>Maverick Solar Enterprises, Inc.</b></div><div class="ApplePlainTextBody"><b> \u2022 Solar Commander Remote Power</b></div><div class="ApplePlainTextBody"><b> \u2022 SunFlow Systems Cathodic Protection <br></b>maverick@mavericksolar.com<br>512-460-9825</div><div class="ApplePlainTextBody"><br></div></div></div><div dir="ltr"><br><blockquote type="cite">On Apr 12, 2022, at 9:42 PM, Ron Young via RE-wrenches <re-wrenches@lists.re-wrenches.org> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr">\ufeff<meta http-equiv="Content-Type" content="text/html; charset=utf-8">Hi Wrenches, trying to wrap my head around a first time Sol-Ark install. Because the max DC voltage is 500v at 18a and the PV I\u2019m using is 40v DC each I will have to create three strings each 480v. What would be the best choice for a home run wire? I\u2019ve always used smaller strings with micro inverters, a combiner at the array and a single Teck home run cable but the string inverter presents a different scenario and it looks like I\u2019ll need to use three home run cables, one for each string. <div class=""><br class=""></div><div class="">Ron Young</div><div class=""><br class=""></div><div class=""><div style="color: rgb(0, 0, 0); font-variant-caps: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px;">earthRight Products - <a href="http://Solareagle.com" class="">Solareagle.com</a><br class="">Alternative Energy Solutions ~ Renewable Energy Products<br class=""><br class=""><br class=""></div></div><span>_______________________________________________</span><br><span>List sponsored by Redwood Alliance</span><br><span></span><br><span>Pay optional member dues here: http://re-wrenches.org</span><br><span></span><br><span>List Address: RE-wrenches@lists.re-wrenches.org</span><br><span></span><br><span>Change listserver email address & settings:</span><br><span>http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org</span><br><span></span><br><span>There are two list archives for searching.
