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 class=""><br class=""></div><div class="">In my case one of the batteries was 23.7 V but still accepted a charge and have apparently functioned well for the customer. Job was installed by others.</div><div class=""><br class=""></div><div class="">I hope that helps. </div><div class=""><div class="">Wallace Stahle</div><div class=""><div class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div>Future Electric Energy Co</div><div>PO Box 236</div><div>Willits, CA 95490</div><div>707-459-0474</div><div>Lic.#C10-762093</div><div><a href="mailto:future@pacific.net" class="">future@pacific.net</a></div><div class=""><br class=""></div></div></div></div></div><div class=""><div><blockquote type="cite" class=""><div class="">On Jul 27, 2022, at 6:58 PM, Howie Michaelson via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" class="">re-wrenches@lists.re-wrenches.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div dir="ltr" class=""><div class="gmail_default" style="font-family:verdana,sans-serif">Hi All,</div><div class="gmail_default" style="font-family:verdana,sans-serif">I was called into a job of a previously off-grid system that new owners
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" class=""></div><div class=""><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><span class=""><span class=""><font color="#888888" class=""><span style="color:rgb(120,63,4)" class=""><b class="">Howie Michaelson<br class=""></b></span><span style="color:rgb(0,0,255)" class=""></span></font></span></span><span class=""><span class=""><span class=""><span class=""><font color="#888888" class=""><span style="color:rgb(106,168,79)" class=""><b class="">Sun Catcher</b></span><br class=""><span style="color:rgb(68,68,68)" class=""><span style="background-color:rgb(255,255,255)" class=""><font size="2" class="">
