KSTAR C&I Hybrid Inverters

Supported Devices

Device Type	Variants	Modbus TCP (Ethernet)	RS485	Curtailment	Minimum device firmware version
BluePulse Hybrid Inverter	KAC50DP-BC100DE	✅	✅	✅	V000B060D000
	KAC50DP-BC107DE / KAC50DP-BC107DE2
	KAC50DP-BC197DE / KAC50DP-BC197DE2

The Sunlight Group EMS and the KSTAR inverters communicate via Ethernet or RS485.

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

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 Sunlight Group EMS will find them faster!
For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The Sunlight Group EMS will scan on those first.
