<div dir="ltr"><div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">I don't want to add a device that provides a separate (different) state of charge than what is reported by the BMS itself. That is just going to lead to confusion and complaints from the homeowner. I was hoping the Sol-Ark could feed SOC and voltage information to a simple external display. I'm leaning toward the cheap tablet idea, but that isn't ideal because the Sol-Ark app doesn't automatically refresh, so it can't be used to display the current SOC without physical interaction. I suppose I could use a web browser with an auto-refresh feature. But this isn't really what I had in mind.</div><div><div dir="ltr" class="gmail_signature"><div dir="ltr"><br>Jason Szumlanski<div><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">Principal Solar Designer | Florida Solar Design Group</span><br style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px"><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">NABCEP Certified Solar Professional (PVIP)</span><br style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px"><span style="color:rgb(51,51,51);font-family:Roboto,RobotoDraft,Helvetica,Arial,sans-serif;font-size:13px">Florida State Certified Solar Contractor CVC56956</span></div><div><font color="#333333" face="Roboto, RobotoDraft, Helvetica, Arial, sans-serif">Florida Certified Electrical Contractor EC13013208</font></div></div></div></div><br></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Feb 5, 2024 at 9:02 AM Chris Schaefer 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:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr">Why not revert to the tried, trued and tested Trimetric 2030 from Bogart engineering?

I have a client with a simple voltage based meter for lead acid batteries that they are accustomed to using as a quick and approximate gauge of SOC. They want something similar for their new Sol-Ark with EG4 LL batteries. <div dir="auto"><br></div><div dir="auto">They will have smartphone app visibility, but they want something they can see inside the house without picking up a phone or going out to the inverter. Ideally the SOC will come from the inverter or the battery itself, not an external source (to avoid discrepancies).<br><div dir="auto"><br></div><div dir="auto">Jason Szumlanski</div><div dir="auto">Florida Solar Design Group </div></div></div>
