In a parallel system, the length and model of the cable between the cabinet and the DGs must be the
same.
Multiple lithium battery cabinets have been configured. This section uses three lithium
battery cabinets connected in parallel as an example.
The number of each lithium battery cabinet is determined by the parallel cable
connection mode. The master cabinet with a display is cabinet 1, the lithium battery
cabinet connected to the BCU_OUT port of cabinet 1 is cabinet 2, and the like.
