Compatibilidad del Dispositivo
Esta integración fue probada con el dispositivo Venus C. Sin embargo, otros dispositivos que utilizan el mismo protocolo de comunicación, como Venus E, también pueden ser compatibles. Si tiene un dispositivo así, es probable que funcione, pero estamos a la espera de confirmación oficial por parte del fabricante.
Cableado
El SmartgridOne Controller y los inversores Marstek se comunican a través de RS485.

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- |
| GND | RS GND | GND | Not available | G |
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.
