The sum Isc of the four strings is 22.64 adc. I want to use either a HU361(30 amp) or HU362(60 amp) as a disco at the inverter instead of running individual strings a long distance from the arrays to the factory-supplied SMA fused disco. So the Isc rating for the HU361 Is 11.5 amps per pole, the HU362 is 38 amps per pole. Although not clear in the SQD datasheet, I think that if two poles are series together the DC(non-pv dc) rating is a full 30 amps for the HU361, and 60 amps for the 362. But the limiting factor in a PV application is the per-pole Isc rating, regardless of putting 2 poles in series (this does not increase the Isc rating of the respective disconnect), correct? I’m assuming my only choice in this instance is to use the 60 amp disco?<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:14.0pt'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt'>Kirk Herander<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt'>VT Solar, LLC<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt'>dba Vermont Solar Engineering<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt'>NABCEP<sup>TM </sup>Certified installer Charter Member<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt'>NYSERDA-eligible Installer<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt'>VT RE Incentive Program Partner<o:p></o:p></span></p><p class=MsoNormal>802.863.1202<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
