I'm getting this error. can you help?

Hello Jorge,

Could you please send me the code you are running that produces that error so that I can try to reproduce it on my side? Also, but inverter model do you use and what firmware version?

JorgeGoncalves1 commented 8 months ago

Hello,

Thanks for your reply.

I don't know how to check the firmware version, if you could help me I would appreciate it.

But the X3-MIC/PRO-G2 10KW inverter was purchased and installed last week, so it must have the latest version..

I tried using the software on two inverters (X3-MIC/PRO-G2 10KW and X1-Boost/Air/Mini 5KW) and got the same error.

Here is the software and the message obtained.

I hope you can help me resolve it.

Thanks Jorge

from solaxx3.rs485 import SolaxX3

I Also tried

The ORIGINAL PROGRAM JUST CHANGE THE BAUD RATE TO 9600

from solaxx3.rs485 import SolaxX3

adjust the serial port and baud rate as necessary

s = SolaxX3(port="/dev/ttyUSB0", baudrate=9600)

if s.connect(): s.read_all_registers()

available_stats = s.list_register_names()
for stat in available_stats:
    print(stat)

battery_temperature = s.read("temperature_battery")
print(f"\n\nBattery temperature: {s.read('temperature_battery')}")

else: print("Cannot connect to the Modbus Server/Slave") exit()

Hello Jorge,

This is how I get the firmware version from my inverter: From the display of the inverter I navigate to the following paths:

After doing some tests on my side, I suppose the error you get is because the program does not see any register at address "2" (which is kind of weird). Please send me the firmware information and also try with the following requirements package versions: pymodbus==3.6.3 pyserial==3.5

Also please run the following program and send me the output (it should display 2 lists with all registers):

from solaxx3.rs485 import SolaxX3

# adjust the serial port and baud rate as necessary
s = SolaxX3(port="/dev/ttyUSB0", baudrate=115200)

if s.connect():
    s.read_all_registers()

    print(f"Input registers: {s._input_registers_values_list}")
    print(f"Holding registers: {s._holding_registers_values_list}")

else:
    print("Cannot connect to the Modbus Server/Slave")
    exit()

Hello Jorge,

It looks like the program does not see any memory location in your inverter's registers, so you get an error because of that. Please contact the Solax support and ask them about how to configure your inverter to be read from a program via RS485 RTU.

Sorry I could not help.
