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.</p><p class="MsoNormal"> </p><p class="MsoNormal">Thx</p><p class="MsoNormal">Peter Giroux</p><p class="MsoNormal">American Solar & Alternative Energy Solutions inc</p></div></body></html>
