DESS Draining batteries to grid

HI
Most mornings around 0600-0700 are batteries are emptied to the grid until we have low battery warnings and the system starts using power from the grid.

What is the best way to prevent DESS from draining the batteries in the morning? We have no issue sending excess solar to the grid.

Do we simply disable discharge battery to grid?

This morning ive added a restriction between 0000-1100 to see if this helps. Im wondering if it will empty them when 1100 comes around.
