<div dir="auto">Dana,<div dir="auto">Sounds like potentially the same issue I've been dealing with in a new Sol-Ark 15 paired with Fortress eVault Maxs. Apparently, Sol-Ark did a recent firmware update that caused erratic closed loop communication between the inverter and batteries. I don't know if the Sol-Ark firmware update effected other inverter sizes. This Sol-Ark update resulted in weird charging behavior and odd generator run times. Apparently, Fortress was unaware of this communication issue until I and a few other installers started reporting the odd behaviors. Fortress sent me a "beta" firmware update which appears to have solved the problem. We're still waiting to update a larger system to make sure the new firmware is stable and fully effective. In any case, this may or may not be the issue in your case, but it may be worth raising the issue with AES and Sol-Ark.</div><div dir="auto">Howie</div><div dir="auto"><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Sun, Dec 4, 2022, 8:22 AM Dana Orzel via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank" rel="noreferrer">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">
