11KTLX-G with LSW-3 download problem

[paku2020]

Hi.

Thanks for the integration, great job :) I wanted to run it in my installation. Yesterday I launched Sofar 11KTLX-G with LSW-3 usb wifi. The logger is in the LSW3_15_270A_1.32 software version. The problem is that the HA is downloading strange data or not. They are all zeros. Look: or See "Installation of PV-SofarSolar Total generation time" 3 932 176 h? :) Something is wrong.

The installation works fine and is fine. The inverter does not display errors and is generating electricity. Does anyone have a similar problem?

greetings

Hi @paku2020 , can you confirm that you specified the sofar_lsw.yaml file in the configuration. If not it will default to deye and the parameters will be zeros.

  - platform: .....
    name: ...
    inverter_host: ...
    inverter_port: ...
    inverter_serial: ...
    scan_interval: ...
    lookup_file: sofar_lsw3.yaml <-- this parameter

Hi, That's what I defined :) Today I did the integration again, from scratch. It looks like: I have a new version of 11KTLX-G3. Maybe this is the problem?

The same problem. Maybe anyone has an idea how to fix it?

Hi @pelemarse @paku2020 , I see that @dsgepers managed to get this right (see issue https://github.com/StephanJoubert/home_assistant_solarman/issues/27 ). Have you managed to solve?

[pelemarse]

#27 bad configuration ip address. In this case everything is fine with IP, I know registry 0000 is read well, but there are problems with other registries. I have the same equipment 11KTLX-G with LSW-3.

[paku2020]

@StephanJoubert Hi, In my case, the IP address is correct. Even some data is backed up from the inverter.

I have exactly this issue with a new Sofar KTLM-G3 - exactly the same data corruption noted above by @paku2020. IP and other config is correct.

Is there a different data format for newer inverters or loggers?

Totally same problem. Inverter: 12KTLX-G3 Logger: LSW3_15_270A_1.53 (Serial: 236xxxxxxx)

Was playing with different registers but no luck. At least it shows something, but not was expected. And there is no information what registers means what. Have found an old (2017) PDF with register table but they not work.

Hope somebody will find solution to this...

Hello try with this registers, should be ok

`requests:

• start: 0x0404 end: 0x042E mb_functioncode: 0x03
• start: 0x0484 end: 0x04BC mb_functioncode: 0x03
• start: 0x0584 end: 0x0589 mb_functioncode: 0x03
• start: 0x0684 end: 0x069B mb_functioncode: 0x03`

Hi. I have LSMW3_15_270A_1.50 and SOFAR 8.8KTLX-G3 and same issue. Has anyone solved it please? I think it might be the registers. But I dont know what to use. ?..?

You might want to try this: https://gist.github.com/Floppe/83365483954d8bcee8d8854eeb3fa818

[waaslandwolf]

I have the same setup (LSMW3_15_270A_1.50 and SOFAR 8.8KTLX-G3) and same issue. I also tried this yaml file but it also doesn't work: https://gist.github.com/Floppe/83365483954d8bcee8d8854eeb3fa818#gistcomment-4584361

[waaslandwolf]

I finally got it working with this file: custom_parameters.yaml.txt (with LSMW3_15_270A_1.50 and SOFAR 8.8KTLX-G3)
