How does the "MKS" work mode work?

Please be advised that this mode is only available for Pakistan users, it is suitable for customers who have higher electricity consumption during certain periods of the day and lower consumption at night. When solar power is available, this mode is basically the same as the SBU mode, and the discharge range of the battery is wider than that of the SBU mode. The difference lies in the fact that the battery only starts charging and the load switches to grid power when the battery voltage falls below the minimum discharge voltage. Normal operation is resumed only when the battery is charged to a voltage higher than the maximum charging voltage. At night when solar power is unavailable, this mode is basically the same as the SUB mode, with the battery only charging and not discharging, which prevents the battery from being depleted.
