Not reading anymore from SOLARMAN LW3

[Mak69]

Inverter ZCS 1PH HYD 6000 ZSS HP + SOLARMAN USB LW3 stick. Yesterday my LW£ performed a self update to firmware version LSW3_15_270A_1.68 Since yesterday Home Assistant can't read anymore the inverter parameters. I was using hyd-zss-hp-3k-6k.yaml file. If I go into the solarman integration configuration menu I can't find anymore this file even if it's present in /custom_components/solarman/inverter_definitions. What I'm doing wrong? Thx in advance

I think I have the same issue:

I have no plan how to fix.

Same issue here. Firmware is now LSW3_15_270A_1.68 and the Solarman integration in Home Assistant is now broken. It shows all PV values as "unavailable".

I did some troubleshooting and managed to fix it. The issue was that the customer inverter definition "custom_parameters.yaml" seems to have been deleted during the upgrade. Because of this, the Solarman HA integration cannot find the register definitions and doesn't know how to map the values it receives from the PV installation's dongle to Home Assistant variables. Once I restored a backup copy of the "custom_parameters.yaml" file to the custom_components\solarman\inverter_definitions folder and restarted Home Assistant, the integration was back up & running as normal.

To fix this, (in Home Assistant) go to Settings - Devices & Services and select the Solarman integration. Click the Configure button. Note the filename of the inverter integration file as configured. For me this is "custom_parameters.yaml".

Now open a file explorer and navigate to your Home Assistant config folder (this will require the Samba add-onto be set up in your HA). Copy a backup of your inverter integration file into the folder \config\custom_components\solarman\inverter_definitions.

Restart Home Assistant, and the Solarman integration should be working again.

I hope this helps, and that you have good backups and manage to fix this. Happy holidays and best of luck!

I was using hyd-zss-hp-3k-6k.yaml file. If I go into the solarman integration configuration menu I can't find anymore this file even if it's present in /custom_components/solarman/inverter_definitions. What I'm doing wrong? Thx in advance

You could try to rename (or even better, make a copy of) your "hyd-zss-hp-3k-6k.yaml" file to "custom_parameters.yaml", and then configure that in the SolarMan integration. Restart Home Assistant, and with a bit if luck this could work.

Does anyone have the custom_parameters.yaml file for a sofar 5ktlm g3?

Does anyone have the custom_parameters.yaml file for a sofar 5ktlm g3?

this works for 11ktlx-g3 https://gist.github.com/MatteCarra/3524c1c29f4ef58028ae3d182694490f

custom_parameters.yaml-working.txt This one works with Sofar 8.8KTL-X. You can try to see if it works with your inverter.

Did someone have a working configuration YAML for LSW3_15_270A_1.68 firmware?

[Vityok01030103]

Привет. Имеется Sofar 8.8KTLX-G3. Подскажите, пожалуйста, возможно ли сделать работу инвертора от 190 воль? А то при 195 вольтах он уходит в защиту. Может кто знает решение? Спасибо.

Прошивка на нем такая. LSW3_15_270A_1.68
