Hi, I have the same device, and from the log I'd day I have the same issue. Did you or somebody else resolved this? |

Still nothing @stokifan . Have you tried asking the seller for more info I tried a couple of times without any success. Also the inverter from time to time does not report any data to the cloud service on the app and looks like the inverter is off. It actually continues producing I can see it from the smart meter that I have on my house and read also with Homeassistant. Seller replaced inverter but same stuff so I decided to leave it like that. |

Hi, thanks for the Update. I made an enquiry to the Manufakturer, I will report any progress there. |

I reverse engineered this one a bit over the weekend. Will publish details soon (next weekend?), but basically it's a messed up modbus protocol that only implements one command: reading register 0. Querying any other register gives you a modbus "ack, but please wait, this is gonna take some time" and then it never finishes, that's the AcknowledgementError you are seeing. But when you query register 0 it always dumps the full state no matter how many bytes you request. The 16 bit registers are:
There are a few more fields, the payload is the same as the cloud upload, so all the data is in there. |

Hi, I did the same, my results see here: davidrapan/ha-solarman#624 (comment) The PV current is tricky as it has at least one gain change, there is temperture too (also with gain change and offset) |

As I'm not a Home Assistant user (yet), I provided also a summary at the pysolarmanv5: https://github.com/jmccrohan/pysolarmanv5/issues/11#issuecomment-2930167019 |

Yeah, I'm currently just gathering data over the week and then I'll try to correlate it with what I see in the app. Since the cloud protocol uses the same data format (but different framing and some extra stuff) it should be possible to reverse engineer the formulas for current and temperature. |

I've cleaned up the Wireshark dissector I used to reverse engineer the protocol a bit, might be helpful for debugging: https://github.com/emmericp/solarman-dissector |

Good day to all,
I am currently stuck in integrating the inverter that I have received.
The documentation for such inverter is very poor.
Any ideas if anyone has solve it will be awesome
I keep getting this logs.
