Explanation
◆
RS232 communication: BMS can communicate with the upper computer through
RS232 interface, so that it can monitor various information
of the battery through the upper computer, including
battery voltage, current, temperature, status and battery
production information.
◆
RS485 / can communication: can communication, used for inverter communication.
◆
RS485 communication: With dual RS485 interfaces, you can view the information
of the pack. If it is necessary to communicate with the
monitoring equipment through RS485, the monitoring
equipment, as the host, polls the data according to the address,
and the address setting range is 1 ~ 15.
