When the battery reaches 85% SoC on the day, the increment for that day is canceled and the limit remains the same as the previous day. If the battery reaches 95% on any day, the dynamic discharge limit is lowered by 5%. The result is that the battery reaches a healthy charge of between 85% and 100% SoC every day.

Maybe? If you get grid to disconnect then the batteries will discharge. If it is the other inverters that you would like to discharge then use ac2 out and program a soc assistant to cut off their power. Would need more info about your setup to see.
A battery is an electrical component that is designed to store electrical charge (or in other words - electric current) within it. Whenever a load is connected to the battery, it draws current from the battery, resulting in battery discharge. Battery discharge could be understood to be a phenomenon in which the battery gets depleted of its charge.
Batteries charge up fine during sunlight (well, to Max 98% for some reason) but when load is required over and above what the panels are putting out, the inverter always pulls the extra power needed from the grid when there are a couple of perfectly good and charged batteries installed.
If it is the other inverters that you would like to discharge then use ac2 out and program a soc assistant to cut off their power. Would need more info about your setup to see. A simpler way for the others may also be timer switches or smart plugs with timers depending on how they are connected to the mains supply.
