Wiring

The SmartgridOne Controller and the KSTAR inverters communicate via Ethernet or RS485.

Ethernet

For correct ethernet wiring: Follow the the guidelines for ethernet wiring.

RS485

Configuration

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.
