Autarco LQH系列 RS485 接线

logo

本页面描述了通过 Modbus-RTU (rs485) 与 Autarco LqH系列混合逆变器的通信。 默认情况下,逆变器设置为地址 1。RS485 通信通过位于逆变器底部 保护板后面的 RJ45 接口进行。确切位置在下图的橙色框中标出:

RS485 端口的引脚定义如下 (EIA/TIA 568B):

  • 引脚 5 上的 RS485A: 蓝/白
  • 引脚 4 上的 RS485B: 蓝

NOTE: RS485 Device Addresses
  • You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
  • Use lower addresses first (1, 2, ...) because the SmartgridOne Controller will find them faster!
  • For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The SmartgridOne Controller will scan on those first.

在与 SmartgridOne Controller 通过 Modbus-RTU 协议成功建立 RS485 连接和通信后, Autarco 逆变器将会在其状态指示面板上显示一个新的蓝色图标:
