Lux 3600 ACS Inverter and 4 Greenlynx Batteries Settings for force discharge

Looking for some advise on the best settings for force discharge 
And was told the batteries could be set the cut off (SOC) to 0 but when it gets down to 15% it starts charging and showing in Yellow as the attached photo.

    Any adjustment would need to be done on the 'maintenance' tab - you've only posted a screendump from the 'monitor' tab.

    That's showing that forced discharge should stop at 25%SOC.

    No idea how it ever managed to get down to 15%.  Or indeed why it started charging.

    I’m sorry that was the wrong photo! This is the one i intending sending, i was led to believe you could set your batteries down to zero! But as can it started charging around 18% SOC and showing in yellow.
  • My batteries start to be charged automatically and the display changes to yellow when the battery voltage goes below the minimum Voltage set for my batteries (Uhome).  This starts as soon as my battery voltage falls below 49V.  What is the minimum voltage for your make of battery?  Has it been set correctly?  I've had the battery voltage fall below 49V even when the SOC was reading 53%!  The BMS sometimes gets the SOC terribly wrong, especially when the batteries haven't been fully charged for several days.

    Looking at the times it has turned to yellow it’s never shown low voltage !
