<div dir="ltr">Steve and Jerry, <div>Thanks for the suggestions. I'll have to take a closer look at the battery bank next time I am out there. </div><div>The solar setup is 4 strings of 3 kyocera 270's into each charge controller. So that is almost 65A @50V coming out of each charge controller for bulk. The parallel battery strings all have the same length of premade cable, so current should be balanced (unless there is a dead cell or two in there...).</div><div>Cheers, </div><div>Dave<br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div dir="ltr"><div><br></div><div><b><font face="tahoma, sans-serif">Dave Tedeyan, PE</font></b></div><div><font face="tahoma, sans-serif">Senior Engineer | Taitem Engineering, PC</font></div><div><font face="tahoma, sans-serif"><img src="https://www.taitem.com/signatures/logo.png"><br></font></div><div><font face="tahoma, sans-serif">110 South Albany Street</font><span style="font-family:tahoma,sans-serif"> | Ithaca, NY 14850</span></div><div><font face="tahoma, sans-serif">o. <u>607.277.1118 x121</u> f. 607.277.2119</font></div><div><font face="tahoma, sans-serif"><a href="http://www.taitem.com" target="_blank">www.taitem.com</a></font></div><div><br></div><div><span style="font-family:tahoma,sans-serif;font-size:10pt;line-height:14.2667px">Solar </span><span style="font-family:tahoma,sans-serif;font-size:10pt;line-height:14.2667px">\u2022</span><span style="font-family:tahoma,sans-serif;font-size:12.5pt;line-height:17.8333px"> </span><span style="font-family:tahoma,sans-serif;font-size:10pt;line-height:14.2667px">Sustainability </span><span style="font-family:tahoma,sans-serif;font-size:10pt;line-height:14.2667px">\u2022 </span><span style="font-family:tahoma,sans-serif;font-size:10pt;line-height:14.2667px">Energy </span><span style="font-family:tahoma,sans-serif;font-size:10pt;line-height:14.2667px">\u2022 </span><span style="font-family:tahoma,sans-serif;font-size:10pt;line-height:14.2667px">Design</span><br></div><div><span style="font-family:tahoma,sans-serif;font-size:10pt;line-height:14.2667px"><span style="font-family:Tahoma,sans-serif;font-size:13.3333px">Certified B-Corporation since 2013</span><span style="font-size:13.3333px"><br></span></span></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div></div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Apr 28, 2020 at 11:52 AM Jerry Shafer <<a href="mailto:jerrysgarage01@gmail.com">jerrysgarage01@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="auto">Sounds like a battery issue at first glance, as you EQ a battery it gets warm or even hot and this will effect ability to charge. If e en one of the L-16 is not exactly the same voltage you will not get to EQ untill another battery over voltages to show your overall volts. Need to look at each battery volts under this charge condition. Also if you have a battery acting up be very careful working around them.<div dir="auto">Jerry</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Tue, Apr 28, 2020, 6:50 AM Dave Tedeyan <<a href="mailto:dtedeyan@taitem.com" target="_blank">dtedeyan@taitem.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Hi All, <div><br></div><div>I've got an outback system (Radian 8048A, 2 FM80, 16 Trojan L16RE-B) where when the customer equalizes, the batteries hover right around the EQ voltage, but will often dip to 0.1v less. Because of this, the EQ timer does not count down properly, and so left to its own devices the system would equalize for way longer than it should, potentially forever. This will happen when doing an EQ from the solar on a bright sunny day, or the generator, or both. The customer can manually keep track of the time and manually stop the EQ after 3 hours, but that is not ideal.
