The SmartgridOne Controller supports Regitec Hybrid inverters via both Modbus TCP (Ethernet) and Modbus RTU (RS485).
| Device Type | Modbus TCP (Ethernet) | RS485 |
|---|---|---|
| Regitec Hybrid Inverter | ✅ | ✅ |
For correct ethernet wiring: Follow the the guidelines for ethernet wiring.
| 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 |
Ensure the termination resistor is set correctly if the inverter is at the end of the RS485 bus.
The Regitec driver is strictly configured for a Baud Rate of 9600. Ensure the inverter is not set to 19200 or 115200, as this will prevent communication.
