<div dir="auto">The PS inverters (buzz-masters, as we call them) do not have a display. A display would be necessary to even attempt to set up for lithium. One could obtain a display in the past but doing so now may be iffy. It may be possible to use a display from an old SW. I am not clear on that. <br clear="all"><br clear="all"><div><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><br>William Miller<br>Miller Solar.com<br>805-438-5600<br><a href="http://www.millersolar.com">www.millersolar.com</a><br></div></div></div><div><br></div><div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Wed, Apr 22, 2026 at 10:52 AM Chris Daum 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:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div lang="EN-US" link="#467886" vlink="#96607D" style="word-wrap:break-word"><div class="m_247652417561297330WordSection1"><p class="MsoNormal">Hi folks:<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Some of these antiques just won’t die. I have a fellow with a Trace PS2512 in his RV (lightly used). He’s very interested in lithium batteries – there is no PV in this system; his battery charging is done by shore power or generator. Is there any sort of remote that will work with his old beast, so he can accommodate the LFP technology? Or is he doomed to upgrade his inverter? Any advice is very helpful. Of course, the manual for the PS series doesn’t mention LFP technologies!<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="MsoNormal">Best,<u></u><u></u></p><p class="MsoNormal"><u></u> <u></u></p><p class="m_247652417561297330MsoAutoSig">Chris Daum<u></u><u></u></p><p class="m_247652417561297330MsoAutoSig">Oasis Montana Inc.<u></u><u></u></p><p class="m_247652417561297330MsoAutoSig">406-777-4309 <u></u><u></u></p><p class="m_247652417561297330MsoAutoSig">406-777-4309 fax<u></u><u></u></p><p class="MsoNormal"><a href="http://www.oasismontana.com/" target="_blank">www.oasismontana.com</a><u></u><u></u></p></div></div>_______________________________________________<br>
