How does the "SBU" work mode work?

Please be advised that this mode is only available for Pakistan users, it is suitable for applications where electricity prices are high and solar power cannot be fed into the grid. Solar power is prioritized for loads, and excess power is stored in the battery for later use. This mode is ideal for customers with low daytime electricity consumption and higher nighttime electricity consumption. Loads are primarily powered by solar energy. If the solar power is insufficient, the battery will provide power. If the battery voltage drops below the voltage threshold for switching to grid supply in SBU mode, the loads will be powered by the grid. Once the battery voltage reaches the voltage threshold for switching back to solar and battery supply, the loads will be powered by solar power and the battery again. If the solar power generated exceeds the load demand, the excess power will be used to charge the battery. In this mode, zero export is enabled by default, meaning power cannot be fed back to the grid.
