Cable selection starts with both devices
Confirm the exact BMS model, inverter model, communication interface, protocol, connector, pinout, firmware, and settings before selecting a cable.
Some cables are for service or computer connection, while others are for inverter communication. The use case must be confirmed before ordering.
Protocol checks before shipment
For CAN or RS485 systems, confirm baud rate or CAN bitrate, supported inverter profile, wiring role, and whether an adapter, display, or module is required.
