Connecting to INVT iMars BG20KTR-US inverter with LSW-3

[Jochey]

Hello,

I am trying to connect to my solar inverter INVT iMars BG20KTR-US with an LSW-3 wifi stick connected. Firmware LSW3_14_8401_1.15

I am able to connect, but get the error "The data address received in the request is not an allowable address for the server."

Any advice on how to solve this issue? I have tested several of the different invert configs.

Hi @Jochey, that means you are requesting wrong registers from the device so you need to use different definition profile. You gonna have to either try some other available and see if any will match your device or write your own.

Thank you @davidrapan. I have tried all the definition profiles but none of them is working straight out of the box. For the afore_hybrid I get the message 2024-08-07 20:50:14.370 WARNING (MainThread) [custom_components.solarman.api] Querying (507 - 560) failed. #0 [V5FrameError: V5 frame does not contain a valid Modbus RTU frame]. I guess this might be a good place to start?

Any hints on how to identify the changes I need to make for a new profile?

[davidrapan]

I was trying to find something but no luck yet :-/ Crucial will be to find similar device from different brand as many of them share hw inside and just branding is changing and it looks like that Afore could be a good candidate.

Also on the github page of library which is used here: https://github.com/jmccrohan/pysolarmanv5 you can find out how to manually scan registers but it is very tedious and long job... :-/

Turn on debug and show me the frame it's complaining about.
