Basically the (Solaredge at least) inverter will not connect unless the generator frequency is within normal grid tolerance, which would be rare with a typical house generator. But if it did connect, and the generator kw were less than the inverter kw, it could potentially turn the alternator into a motor, spinning it backwards.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:16.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Kirk Herander<o:p></o:p></span></b></p><p class=MsoNormal><b><span style='font-size:16.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Owner|Principal, VT Solar, LLC <o:p></o:p></span></b></p><p class=MsoNormal><b><i><span style='font-size:16.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Proven PV provider since 1991<o:p></o:p></span></i></b></p><p class=MsoNormal><b><span style='font-size:16.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><a href="www.vermontsolarnow.com">www.vermontsolarnow.com</a><o:p></o:p></span></b></p><p class=MsoNormal><span style='font-size:16.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>dba Vermont Solar Engineering<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:16.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>NABCEP<sup>TM </sup>2003 Inaugural Certificant<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:16.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>VT RE Incentive Program Partner<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:16.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>802.863.1202</span><span style='font-size:14.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:18.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><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"'> RE-wrenches [mailto:re-wrenches-bounces@lists.re-wrenches.org] <b>On Behalf Of </b>Howie Michaelson<br><b>Sent:</b> Tuesday, October 20, 2015 12:01 PM<br><b>To:</b> RE-wrenches<br><b>Subject:</b> [RE-wrenches] Generator backfeeding enphase?<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p><p>Does anyone think that there is no issue with having enphase potentially backfeeding a backup generator?
