SolaX X3-Ultra 25K - Export Control Modbus register address?

[nnikolov1976-hub]

Hi,

I have a SolaX X3-Ultra 25K (SN: H3BC25) running locally via Modbus RS485.

I am trying to find the holding register address for Export Control User Limit on the X3-Ultra.

I have the official "Hybrid X3-ULTRA Modbus RTU V1.01" PDF but it does not include this register - it references a detailed .xlsx file which I don't have.

I scanned all holding registers 0x0000-0x01FF and cannot find a register that consistently changes when I update Export Control from SolaX Cloud.

Does anyone know:

1. The holding register address for Export Control User Limit on X3-Ultra?
2. Does anyone have the "Hybrid X3-ULTRA Modbus RTU Detailed V1.01-English.xlsx" file?

Thanks!

This should be register 0x42 (write 0x6 function) and 0xB6 (read 0x3 function). That's the register we use in plugin_solax.py which includes the X3-Ultra.
