Info
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 | Sofar EMS model OM1 | Sofar EMS model IG8 | RS485-USB converter | RS485-Ethernet converter |

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 Sofar EMS will find them faster!
- For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The Sofar EMS will scan on those first.
Vaya a “Pantalla Principal” >> “Configuración del Sistema” >> “Función Avanzada.”
- El Modbus SN debe configurarse con un número entre 1 y 247. ¡No seleccione 0! Tenga en cuenta que si hay varios dispositivos en el bus RS485, cada uno debe tener un número único. Esta es la dirección.
- Debe estar marcado como esclavo.
- Solo cuando un medidor adicional esté conectado directamente al inversor debe marcarse “EX_meter For CT”. Si solo hay un medidor en paralelo con el Sofar EMS debe estar desmarcado.
- Asegúrese de que las siguientes configuraciones sean correctas: "Max A Charge", "Max A Discharge", "Grid Charge Ampere"
