Wiring
Ethernet Connection
For correct ethernet wiring, follow the guidelines for ethernet wiring.
RS485 Connection
For models supporting 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 |
|---|---|---|---|---|
| RS485 A | RS485 A | RS485_POS | RS485 A | TX+ |
| RS485 B | RS485 B | RS485_NEG | RS485 B | TX- |
| GND | RS GND | GND | Not available | G |
- Use shielded twisted pair cable
- Maximum cable length: 1000m
- Maintain proper polarity (A to A, B to B)
Configuration
Network Setup
- Connect the inverter to your local network via ethernet cable
- Make sure your IP address is in the same subnet as the Controller
