More specifically, bypass one of the controllers; assuming 48, 60 or 72 Vnom depending on array. Let the other controller remain in normal operation. Send the unregulated array to bring initial battery voltage up; then the other controller takes over and the one that was bypassed now is reconnected. Better if the unregulated array is the smaller of the two, I would suspect.<o:p></o:p></p><p style='margin-left:.5in'>What I'm suggesting will work with flooded lead-acid, and likely VRLA lead-acid as well, as long as the unregulated array is taken out of the system before voltage exceeds bulk. It may not work at all with these Li-I, as I have no experience with restoring them. Daryl may well be right about being unrestorable below a threshold voltage; also the batteries may need an operational BMS to take a charge. So this is perhaps just food for thought.<o:p></o:p></p><p style='margin-left:.5in'>Allan<o:p></o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom:0in;margin-left:.5in;margin-bottom:.0001pt;line-height:normal'>-- <br><br><o:p></o:p></p><p class=MsoNormal style='mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;margin-left:.5in;line-height:normal'><b><span style='font-size:12.0pt'>Allan Sindelar</span></b><span style='font-size:12.0pt'><br></span><a href="mailto:allan@sindelarsolar.com"><span style='font-size:10.0pt'>allan@sindelarsolar.com</span></a><span style='font-size:12.0pt'><br></span><span style='font-size:10.0pt'>NABCEP Certified PV Installation Professional<br>New Mexico EE98J Journeyman Electrician<br>Founder (Retired), Positive Energy, Inc.<br><b>505 780-2738 cell</b></span><o:p></o:p></p><div><p class=MsoNormal style='mso-margin-top-alt:0in;margin-right:0in;margin-bottom:0in;margin-left:.5in;margin-bottom:.0001pt;line-height:normal'>On 2/9/2018 6:16 PM, Gary Rochlin wrote:<o:p></o:p></p></div><blockquote style='margin-top:5.0pt;margin-bottom:5.0pt'><p class=MsoNormal style='margin-left:.5in'>Does anyone have any information or specifications for an older circa 2010-2012 iCel System Lithium Ion Battery. We are doing a repair on an older 48V Lithium Ion system consisting of 3-6 ICel batteries wired in parallel and 1 Xantrex 6848 and 2 Xantrex Conext MPPT 60 150 Solar Charge controllers. Via a surge from SCE system shut down and sat before we were called in. Batteries are sitting at 6.67V and the charge controller will not turn on unless the batteries are at 40V since at the time they were made for lead acid batteries. I\u2019m looking at finding the way to charge the iCel batteries or goose the charge controller into thinking 40V are coming from the batteries.
