[QUOTE="Oldman22, post: 553447, member: 36003"] I think if you were to use a tool like PbmsTools to view what's going on with your batteries overnight, you would see that stopping discharge at 15% isn't absolute and that there will be maybe 1-2% further discharge almost within minutes of the 15% cut off point, then further discharge due maybe to cell imbalance and Inverter overheads taking you down to 11% by morning. Pretty much any percentage below 15% Overdischarge SOC triggered a cycle of charge/discharge cascading for me with 3 x 5kWh batteries. [/QUOTE]
