We did the LG RESU 48v field testing here for Schneider. Never had any problems with this and both of their cc's. Still running fine 2 years later.
What I found was in the effort to get to 100% Soc there would be micro cycles of the battery. By staying below 100% there was not any more issue with this. I keep the charge voltage just slightly lower by a few tenths of a volt and get a 97% Soc. Looks just like my old LA bank on a voltage graph. Never had any problems with lights out on this system, NEVER ! I do once every 3 months or so raise the voltage to 100% Soc to let the BMS balance if it wants to. I sure wish LG would sell the 13.5 KWH in North America. So Sad!

I have used Morningstar MPPT 60 s on my few LiFe po4 systems 4 years now, no controller problems or equipment problems yet. I imagine when the BMS disconnects battery voltage high, controller output goes high for a short period i will put an Egauge on the output to messure voltage on one system to see if i catch an event.
