| Device Type | Variants | Modbus TCP (Ethernet) | RS485 | Curtailment |
|---|---|---|---|---|
| Venus-C | 2.5kWh | ❌ | ✅ | ❌ |
Note
Apparatuurcompatibiliteit Deze integratie is getest met het Venus C-apparaat. Andere apparaten die hetzelfde communicatieprotocol gebruiken, zoals de Venus E, kunnen ook compatibel zijn. Als je zo'n apparaat hebt, is het waarschijnlijk dat het werkt, maar we wachten op officiële bevestiging van de fabrikant.
Bedrading
De SmartgridOne Controller en de Marstek omvormers communiceren via RS485.
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.
