Wiring
The SmartgridOne Controller and the Delta inverters communicate via RS485.
RS485
| Setting | options |
|---|---|
| Baudrate | 2400 / 4800 / 9600 / 19200 (default) / 38400 |
| Data bits | 8 |
| Parity | None |
| Stop bits | 1 |
Configuration
Warning
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.
