Hi, untick the 'Activate' box and i would suggest to increase the charge and discharge values.

The batt specifications suggest  a charge/discharge value of 50A.  You can thus safely increase the values to 150A for the 3 batteries.  The BMS would manage  the chimage.png.c197ff5dfbbf29bdf4aa07200d096dd8.pngarging/ discharging amperages according to the parameters of the battery design and chemistry.

Hi G, this option will help to recover a battery that's been discharged beyond it's lowest threshold by activating a slow charge mode from either the grid or PV.  It is mainly for AGM, flooded or Gel batteries, not lithium.  The BMS controls lithium.
