RS485 Wiring
- For correct RS485 wiring: Follow the guidelines for RS485 wiring.
- If the wiring shown in the table below is incorrect, please let us know.
- There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.
Device | SmartgridOne Controller model OM1 | SmartgridOne Controller model IG8 | RS485-USB converter | RS485-Ethernet converter |
---|---|---|---|---|
A | RS485 A | RS485_POS | RS485 A | TX+ |
B | RS485 B | RS485_NEG | RS485 B | TX- |
N/A | RS GND | GND | Not available | G |
配置
确保启用 modbus:
- 从主页进入“设备”
- 点击“发电站设置”
- 启用“Modbus TCP 服务器启用”

确保逆变器已设置为远程 EMS 模式:
- 从主页进入“系统”
- 点击安装命名空间旁边的三个点
- 点击“系统设置”
- 点击“操作模式”
- 选择“远程 EMS 模式”

禁用任何电网限制:
- 从主页进入“系统”
- 点击安装命名空间旁边的三个点
- 点击“系统设置”
- 在“操作参数”下禁用“出口限制”和“进口限制”
- 将“电网连接点预留功率控制方法”设置为“每相功率”

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.
