<div dir="auto"><div dir="auto">Thanks Wallace. I will return to the site and check the voltage again, but I believe when I read it it was in the teens. However, I did run into the in rush and shut down issue you mentioned the first time I tried restarting, but when I tried it again, the batteries didn't put anything out. I will talk with simpliphi and see if we can get things going. </div><div dir="auto">Howie</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jul 27, 2022, 10:38 PM Wallace Stahle via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org">re-wrenches@lists.re-wrenches.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word">Hold off on that 48 volt charger Howie,<div><br></div><div>I was called a while back with the same issue on a set of five of the same model battery. All shut off internally. Had the same inverter and CC too. I called Simpliphi which I recommend you do also and was told to turn off all inputs and outputs to battery, close the breaker on each unit individually and read the open circuit voltage. If 24 v or above simply close the 3 breakers before engaging the inverter breaker as the capacitor inrush can fool the BMS of the battery and shut it off which I found out when I first shop charged the new batteries individually. If battery shuts down upon inverter connection then toggling the battery breaker again the inverter will connect and you charge with generator as the inverter can now function with the small amount of reserve power present. And/or the solar as conditions dictate.</div><div><br></div><div>In my case one of the batteries was 23.7 V but still accepted a charge and have apparently functioned well for the customer.

had an electrician bring the grid to, but the batteries (
a pair of Simpliphi 3.5, which I have no experience with)
have been dead for an unknown period of time previously.
I am trying to figure out the easiest way to restart the system which has a VFX 3648 and FM60. I'm thinking the easiest way is to bring in a 48volt charger to get the battery voltage up high enough to start the FM60 and/or VFX, but that means purchasing a 48 volt charger, since I don't have any Iotas sitting around any more. If anyone has an easier way to restart the batteries I'd love to hear it.</div><div class="gmail_default" style="font-family:verdana,sans-serif">Thanks,</div><div class="gmail_default" style="font-family:verdana,sans-serif">Howie <br clear="all"></div><div><div dir="ltr" data-smartmail="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><span><span><font color="#888888"><span style="color:rgb(120,63,4)"><b>Howie Michaelson<br></b></span><span style="color:rgb(0,0,255)"></span></font></span></span><span><span><span><span><font color="#888888"><span style="color:rgb(106,168,79)"><b>Sun Catcher</b></span><br><span style="color:rgb(68,68,68)"><span style="background-color:rgb(255,255,255)"><font size="2">
