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/" target="_blank" rel="noreferrer">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" target="_blank" rel="noreferrer">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 style="color:rgb(0,0,0);font-family:Helvetica;font-size:12px"><div>Maverick Brown<br>Off-Grid Solar Commander since 2006<br><b>Maverick Solar Enterprises, Inc.</b></div><div><b> \u2022 Solar Commander Remote Power</b></div><div><b> \u2022 SunFlow Systems Cathodic Protection <br></b><a href="mailto:maverick@mavericksolar.com" target="_blank" rel="noreferrer">maverick@mavericksolar.com</a><br>512-460-9825</div><div><br></div></div></div><div dir="ltr"><br><blockquote type="cite">On Apr 12, 2022, at 9:42 PM, Ron Young via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank" rel="noreferrer">re-wrenches@lists.re-wrenches.org</a>> wrote:<br><br></blockquote></div><blockquote type="cite"><div dir="ltr">\ufeffHi 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><br></div><div>Ron Young</div><div><br></div><div><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">earthRight Products - <a href="http://Solareagle.com" target="_blank" rel="noreferrer">Solareagle.com</a><br>Alternative Energy Solutions ~ Renewable Energy Products<br><br><br></div></div><span>_______________________________________________</span><br><span>List sponsored by Redwood Alliance</span><br><span></span><br><span>Pay optional member dues here: <a href="http://re-wrenches.org" target="_blank" rel="noreferrer">http://re-wrenches.org</a></span><br><span></span><br><span>List Address: <a href="mailto:RE-wrenches@lists.re-wrenches.org" target="_blank" rel="noreferrer">RE-wrenches@lists.re-wrenches.org</a></span><br><span></span><br><span>Change listserver email address & settings:</span><br><span><a href="http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org" target="_blank" rel="noreferrer">http://lists.re-wrenches.org/options.cgi/re-wrenches-re-wrenches.org</a></span><br><span></span><br><span>There are two list archives for searching.
