The HJ048 power system supports multi-module parallel expansion, and battery modules also support parallel expansion. The maximum configuration is 4PSU+4BAT (4 power supplies and 4 batteries), supporting up to 12 power distribution channels. The expansion method involves using the accompanying cascade cable to cascade the battery module's charge/discharge port to the power module's charge/discharge port, then cascading the communication ports.
