<div dir="ltr">Hi Chris,<div><br></div><div>One strategy that I have been using to add intelligence to older systems is to add a Victron shunt and a Victron Ekrano. This allows efficient battery monitoring via a very nice screen and you can hand generator starting duties to the Ekrano. Another potential benefit is the ability to remotely monitor the battery and generator starting control (via Victron VRM), set up some simple alerts and verify the depth of discharge. If you have a battery that supports closed-loop control, you can probably eliminate the shunt, although I prefer having both options (victron can have a primary and secondary battery monitor)</div><div><br></div><div>The Ekrano/shunt combo isn't cheap, but it is quite powerful and can precisely inform future system upgrades.</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Thu, Feb 12, 2026 at 3:42 PM Maverick Brown 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="auto">I have two recommendations<div><br></div><div>Victron smart shunt, which is a Bluetooth device. </div><div><br></div><div>Also, since you have the MidNite classic, you could install a whizbang junior and a shunt.
