Attempting to make it work with my SUN-6K-SG03LP1-EU #12

Hello.

I have one SUN-6K-SG03LP1-EU with one Pylontech 5000 and I'm trying to use this code to read and write from/to the inverter.

I'm having a bit of a hard time understanding how it work as I don't recognize the language/coding show in the examples despite having some programming background (mostly C).

I managed to install it, but doesn't seem to be reading the inverter correctly:

I read the inverter serial number correctly, so it is working up to some level.

[dividi@rocky deye-controller-master]$ deye-read 192.168.192.12 2913021234
[ Device_Type]: Hybrid
[ Modbus_Address]: 1
[ Inverter_Serial]: 2401081234
[ Rated_Power]: 0

struct.error: 'h' format requires -32768 <= number <= 32767

Is there any hint hot to get this working, possibly need to adapt some code to my inverter, but I don't yet have a ModBus manual that I'm sure is accurate for my inverter.

Thanks in advance.

Cheers.
