Is you Inverter PV only? Not sure If I have added in correctly or not? Not entirely sure which register set it should be usinging. How old is the Inverter? |

I have a Growatt MID 17-KTL3-XH Hybrid inverter. Used to work up to 2024.05.07 but stopped after that. Now in 2024.08.13 i get: Got it working again in 2024.08.13 when manually adding the check for "KMN" in growatt_plugin.py. I just uncommented the "MID"-one that was already there and changed it to KMN, seems to work for my purposes but not sure that is correct, just an observation :) |

It is working again in 2024.08.14. It do however think it is reading and matching against the wrong serial number. (not that it really matters). Here is how it looks in 2024.08.14, the serial number seems a bit odd, but it works. |

I should rename it all on the Growatt Inverters really. The "Serial Number" there is actually part of the Firmware version. On other Inverters such as SolaX the first 4-6 digits of the Serial is used to determine the Inverter type. But on the Growatt, the Serial is truly unique, so I had to find something else to detect the model with. |

Not sure if this helps or not. It is working now so I am happy either way, but here is a clip of the info in the Growatt UI for my inverter. Seems the DN1 is actually a buildnumber and it is combined with the communication version. I am quite new to growatt (and solar for that matter) as well so I have no clue if the first tree digits of the actual device serial is unique to the model. I do however have a HA docker image for testing purposes, so if you want some help testing something for growatt (mid 17-ktl3-xh that is) i would be happy to help.

Well, I have 8 inverters running, and 1 has arrived yesterday. 1x SPH 4600 But just one is connected via modbus to Homeassistant or better EVCC which is running as addon unter Homeassistant. Here is my simple architecture of the SPH 4600
My goal is the following setup with HomeAssistant as a proxy in the middle like this, but this is the full picture incl. a modbus connection of 4 modbus meters EASTRON SDM72. This would mean 2 modbus lines and also a third modbus line which is not in the picture right now.
My 3rd modbus line would be the long inverter line of the min and mic inverters, 6 in a row. Finally the SPH 4000 with another battery but that is why I need a proxy for sure. But the other Min and Mic inverters have adresses that I can change.
But how could I setup the "base communication line" cause the SPH 4000 and 4600 should communicate with the Eastron I guess and that would means eastron or via 2 separate lines and 2 RS485 to USB FTDI Adapter ? I know that there is also a setup in the cloud where you should be able to add another inverter to a smartmeter. Please let me know what is possible with the Solax Modbus ! Thanks |

Hi, hope this is still valid. Error Message: |

Does it return more than just V? Or is V all it returns? |
Beta Was this translation helpful? Give feedback.

The Firmware version is only stated as V. However, the log is longer and contains more errors. but the firmware version : V is what brought me here. If you want to have a look (firmware naming almost at the end) |

Hi, I have two Growatt Inverters- MIN 5000TL-X and 7000 MTL-S. These are PV only. It would be great if these could also be added. Thank you |

Is AJ1 for the TL-X or the MTL-S? |

I'm guessing AJ1 is for the TL-X. I have added it in 2024.10.4 Let me know if you can get the MTL-S to return anything. |

If you get the following error in your log:
"unrecognized inverter type - firmware version : {your_firmware_version_here}"Please list below the first 3 digits here including the Inverter type and kW rating and which plugin you got a response with.
I can then add in your Inverter.
Please do not raise an issue in addition.
If you get
unrecognized XYZ inverter type - firmware version : unknownyou don't have a working Modbus connection.Don't raise an issue, this isn't a fault of the Integration.
Either use one of the existing discussions or start a new one, don't comment in this discussion about
