This will require a fourth charge controller. Being able to run smaller wire in the existing conduits is an attractive proposition, making the FM100 a desirable approach. I now have to figure out if I can add the FM100-AFCI (which is apparently the only version available) to a system with three FM80s, and if I do, what do I do with the existing GFDI breaker and how do I arrange the DC bond? There is a lot to consider here.</span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif""> </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif"">BTW, I was told by a tech support person for an on-line sales firm that the original FM100 did not have the AFCI but those units have been discontinued. Now all FM100s have the AFCI capability. I am weighing if I want AFCI if it is not required. My territory includes central California wild lands so I suppose I should take advantage of any fire safety means at my disposal\u2026</span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif""> </span></p><p class="MsoNormal"><span style="font-family:"Verdana","sans-serif"">William</span></p><p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Verdana","sans-serif";color:#1f497d"> </span></p><div><div style="border:none;border-top:solid #b5c4df 1.0pt;padding:3.0pt 0in 0in 0in"><p class="MsoNormal"><b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif"">From:</span></b><span style="font-size:10.0pt;font-family:"Tahoma","sans-serif""> Jay [mailto:<a href="mailto:jay.peltz@gmail.com">jay.peltz@gmail.com</a>] <br><b>Sent:</b> Friday, May 15, 2020 7:34 AM<br><b>To:</b> <a href="mailto:william@millersolar.com">william@millersolar.com</a>; RE-wrenches<br><b>Subject:</b> Re: [RE-wrenches] Outback FM100</span></p></div></div><p class="MsoNormal"> </p><div><p class="MsoNormal">Hi William</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">Yes downsizing breaker to meet load is no problem.
