If battery strings are connected in parallel and need to communicate in cascading mode, the hardware address of each
battery must be configured. The hardware address can be set using the dip switch on the board. When the batteries are
in parallel, address 1 is the host and other addresses are slave.
The battery at address 1 is connected to the inverter; If the address is 0,
it is in single-battery mode
