<p><span style="font-size: 12pt;">I think it is the battery that is most important in closed loop, as that is where the cost/warranty is. I have an email out on this for another friend and will get back. Below is the SMA Island manual for Discover AES battery link. Each Inverter company has a manual from AES for their battery. Not sure why an Inverter make would not want to do this but...</span></p>

<div id="v1v1v1signature">AES is closed loop with 7 inverter manufacturers (not Outback and I do not know why) including SMA. Not sure on the particulars but you should check them out with Lync2 interface. I just use them closed loop with XW and they can charge 40% faster.</div>

<p class="v1v1v1v1MsoNormal">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.</p>
