<p>On the #4 question, if you downsize the breaker you can also downsize the cc output wiring as long as the breaker is still protecting the wiring, as you know. One of the advantages of this controller (or any HVcc) is the higher input voltage is great down the line for adding more solar easily.</p>
<p>In that case you might as well wire and over current protect to what Outback requires.</p>

<p class="MsoNormal"><span style="font-size: 12.0pt;">I have occasion to try the FM100 charge controller. I am wondering of anyone had found any quirks with implementing this device. I have a few specific questions:</span></p>
<p class="MsoNormal"><span style="font-size: 12.0pt;"> </span></p>
<p class="MsoListParagraph" style="text-indent: -.25in; mso-list: l0 level1 lfo1;"><span style="font-size: 12.0pt;"><span style="mso-list: Ignore;">1.<span style="font: 7.0pt;"> </span></span></span><span style="font-size: 12.0pt;">I want to avoid AFCI unless mandated. Will this be defeated if I don't run the leads through the sense coil? (There is an AFCI and non-AFCI version but I can't seem to find the non-AFCI version anywhere.)</span></p>
<p class="MsoListParagraph" style="text-indent: -.25in; mso-list: l0 level1 lfo1;"><span style="font-size: 12.0pt;"><span style="mso-list: Ignore;">2.<span style="font: 7.0pt;"> </span></span></span><span style="font-size: 12.0pt;">I noticed the manual indicates you are not supposed to mix the FM100 with the FM80 or 60 in the same battery system. This negates it for one project I had in mind. I am curious as to why this is. Anyone know?</span></p>
<p class="MsoListParagraph" style="text-indent: -.25in; mso-list: l0 level1 lfo1;"><span style="font-size: 12.0pt;"><span style="mso-list: Ignore;">3.<span style="font: 7.0pt;"> </span></span></span><span style="font-size: 12.0pt;">Will the FM100 work with a standard hub?</span></p>
<p class="MsoListParagraph" style="text-indent: -.25in; mso-list: l0 level1 lfo1;"><span style="font-size: 12.0pt;"><span style="mso-list: Ignore;">4.<span style="font: 7.0pt;"> </span></span></span><span style="font-size: 12.0pt;">I suppose this unit requires a 125 amp breaker. If the PV array cannot support that full 100 amps I might down-size the OCPD accordingly. Anyone contemplate this question?</span></p>
