Im am working with this modbus library via tcp on a Kostal PLENTICORE plus inverter. The inverter offers two options (next to Modbus port and Unit ID) for modbus configuration:
Byte order:
[ ] little-endian (CDAB) Standard Modbus
[X] big-endian (ABCD) Sunspec
At the moment only only big-endian (Suncpsec) is working for me.
