[RE-wrenches] Older Sunny Islands charging newer Lithium's

[William Miller]

Peter:



I have been working at interfacing a set of SIs with LiFPO4 batteries.  It
is documented here
<https://millersolar.com/MillerSolar/case_studies/36_SIFortress/36_SunnyIslandFortressIntegration.html>
.



Because the Sis are so SOc-centric they can be hard to intergrate with
Lithium.

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.



Thx
