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 a-TroniX Controller 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 a-TroniX 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 a-TroniX Controller will scan on those first.
