<div dir="auto">Jay,<div dir="auto"><br></div><div dir="auto">I should mention I have a couple of customers with big EG4 LifePower battery banks (i.e. 120kWh+, 80kWh, etc) and Sol-Arks. The clients purchased the batteries directly, so I didn't have a choice. I will say that the systems are performing flawlessly, but forget about closed loop comms and SOC management. Everything is voltage based, which is suboptimal. But we're making it work. The Sol-Ark app still reports their version of SOC, which is handy for clients, but charge setpoints are done with voltage. </div><div dir="auto"><br></div><div dir="auto">Signature Solar has provided pretty good support, but I didn't need much help. </div><div dir="auto"><br></div><div dir="auto">I strongly suggest the Communication Hub to get SOC data from the battery BMSs. It's pretty handy and very easy to install. </div><div dir="auto"><br></div><div dir="auto">With that said, I don't sell EG4 and don't necessarily recommend it, but to be fair, I haven't had any problems and the capacity claims seem legitimate. The value proposition can't be ignored. </div><div dir="auto"><br></div><div dir="auto">Jason Szumlanski </div><div dir="auto">Florida Solar Design Group</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Oct 9, 2024, 7:29\u202fPM jay <<a href="mailto:jay.peltz@gmail.com">jay.peltz@gmail.com</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;line-break:after-white-space">Thats all super helpful, appreciate the advice everyone. <div><br></div><div>I\u2019ve not used the sol ark 15 and just wanted to make sure I wasn\u2019t missing anything about battery options.</div><div><br></div><div>And specifically the ones that don\u2019t seem to play well.</div><div><br></div><div>Jay</div><div><br></div><div><br></div><div><br></div><div><br><div><br><blockquote type="cite"><div>On Oct 9, 2024, at 2:56 PM, Jason Szumlanski via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank" rel="noreferrer">re-wrenches@lists.re-wrenches.org</a>> wrote:</div><br><div><div dir="ltr"><div dir="ltr"><div class="gmail_default" style="font-family:arial,helvetica,sans-serif">HomeGrid works great with Sol-Ark.
