Hi Scott,
Agree with all you have said and would add that my experience with the failed 48vdc LG RESU 10 proved to me that LG needed to go back and redesign the whole line of residential storage. Not ready for prime time. It probably is just a good choice to stay away from their NMC batteries. No matter what listings they have, it is much safer to use LFP lithium. I have heard that the Tesla powerwall is useable (now) offgrid with warranty. Sadly it is also NMC lithium. The Discover AES and today Fortress are both closed loop (LFP) with Schneider AC coupling or DC. One just sets the current date and configuration is done.

I am glad that you are having good outcomes with BYD but I never said this was part of my problem. So when you say you are "doing it pretty often" I'm assuming you are referring to the BYD battery. SMA acknowledges verbally that this BYD battery offers uninterrupted operations whereas the LG does not. Further, my original post never said a thing about stacking of SBS. As for "how did (I) determine that LG was an approved solution in the beginning:" SMA depicts this in its datasheets quite clearly. In fact, LG Chem is listed before BYD. Bottom line - there is no recharging capability with SMA AC-coupled PV inverter to LG Resu batteries. Links: ------ [1] http://members.sti.net/offgridsolar/ [2] mailto:offgridso...@sti.net
