KSTAR C&I Hybrid Inverters

Supported Devices

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

The EPSherpa 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 a unique address on the RS485 bus. Check the device manual for instructions.
Use lower addresses first (1, 2, ...) because the EPSherpa EMS will find them faster!
For each device, it is generally recommended to keep the factory-default baud rate, parity, and stop bits. The EPSherpa EMS will scan those first.
