A BESS can also be connected to a feeder of a transformer instead of being directly connected to the grid. In such cases, when it is at the high voltage side of the 10/0.4 kV transformer, its category is B high, while at the low voltage side, it is B low. Finally, a direct connection with the LV grid level of 0.4 kV puts it under category C.
