2 years ago Hi @dcelorrio,
The frame you have received, while a valid solarmanv5 frame, doesn not contain a valid Modbus RTU frame.
Have you amended the client example registers to match your Deye Sun Hybrid 8000w device? It will most likely have different Modbus registers.
The client_example.py file is just there to demonstrate how to use the library.

With a deye sun hybrid 8000w , I execute client_example.py and finish with this error . (Device serial number 2330702165 and Inverter serial number 2201144460)
What is the problem?
Thanks
