Sofar HYD 3600-ES "V5 frame does not contain a valid Modbus RTU frame"

[ssimoe50]

Hello,

I'm facing an issue and difficulties with my recent installation.

• Sofar HYD 3600-ES
• Device information:
  • Device serial number: 239XXXXXXX
  • Firmware version: LSW3_15_270A_1.68
  • Connected through WiFi

Just to be sure I tried to scan and it was in fact detected this model:

$ python3 scanSolarMan.py

{'ipaddress': '192.168.X.Y', 'mac': 'E8FDZZZZZZZZ', 'serial': '239XXXXXXX'}

But when I tried to run the basic example (with the correct IP and serial information of course I got this:

$ python3 basicSyncClientTest.py 

Traceback (most recent call last):
(...)
File "testsSolarman/basicSyncClientTest.py", line 17, in main
    print(modbus.read_input_registers(register_addr=33022, quantity=6))
(...)
raise V5FrameError("V5 frame does not contain a valid Modbus RTU frame")
pysolarmanv5.pysolarmanv5.V5FrameError: V5 frame does not contain a valid Modbus RTU frame

Has anyone seem similar and/or has a solution or workaround for this in particular?

Thanks
