<div dir="ltr">Hi Peter,<div><br></div><div>The Sunny Islands will work with Lithium, but there can be challenges. The Blue Ion to Sunny Island communication works really well, you need a Namaka box for that. This would be a great but expensive way to go.</div><div><br></div><div>The difficulties with Sunny Island and no communication to BMS is when you need the Sunny Island to start the generator at a specific state of charge or also know when to shut down. The open loop parameters seem to work just fine for charging.</div><div><br></div><div>One cheap solution that I think would work well is to add a Victron Smart shunt, Cerbo and perhaps a screen. You can manipulate the SOC algorithm in the smart shunt to work well and turn the generator start duties over to the Cerbo. You may also be able to externally trigger the Sunny Island to shut off (haven't looked deeply into this).</div><div><br></div><div>Have a good weekend!</div><div><br></div><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Mar 1, 2024 at 3:10 PM Jerry Shafer 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">SMA and Li Tech<div>I have replaced quite a few batteries with LIPh and the only thing on the 4048's is setting a temp sensor at default 77 Degrees and on the 5048"s as i recall can be closed loop with fortress and Blue Planet.</div><div>Fun Times</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Fri, Mar 1, 2024 at 12:52 PM Peter Giroux via RE-wrenches <<a href="mailto:re-wrenches@lists.re-wrenches.org" target="_blank">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><div lang="EN-US"><div><p class="MsoNormal">My fellow wrenchers. Have sought help from SMA but they just defer to owner’s manuals and the older batteries listed.. I have a customer with two SMA 5048’s, roughly 11 years old and appear to be working fine. Customer wants to move to LIPO batteries and keep his SMA’s. Has anybody made these transitions and how did you do it, not sure the SMA programing for LIPO’s works the way Lithium’s need. Any and all help and ideas appreciated.<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Thx<u></u><u></u></p><p class="MsoNormal">Peter Giroux<u></u><u></u></p><p class="MsoNormal">American Solar & Alternative Energy Solutions inc<u></u><u></u></p></div></div>_______________________________________________<br>
