Unrecognized Inverter - Growatt

[wills106]

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 : unknown you 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 unrecognized XYZ inverter type - firmware version : unknown

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?
Just released 2023.10.2

Sorry for the late reply, unfortunately my Growatt 4600 MTL-S is no longer in operation defect

Hello It is a PV only. Two MPPT. About 10 years
I will test plugin version 2023.10.2
Thank you

@wills106
can be added also:

Device Serial Number：FRJxxxxxxx
Version:GHAA1050
Communication Version Number:ZAAa-0094
Build Number:GH1.0
Device Model:MIC 600TL-X
mppt: 1

and

Device Serial Number：FWFxxxxxxx
Version:ALAA0201
Communication Version Number:ZABA-0002
Mode:S0CB01D00T00P0FU01M002A
Build Number:AL1.0

Guess this is section with need code update to support other inverters.
