Same/very similar problem adding a SolaX X3 Hybrid (which worked fine and was removed before the upgrade from 2024.05.7 as per the release note instructions in the early 2024.08 releases). On HomeAssistant OS 13.1 and core 2024.8.3.

the 'support-battery' seem to be the problem for the config flow when adding the integration according to the logs.

I have the exact same problem. I have not been able to use any 2024.8 versions and have to stay at 2024.5.7

[stefsims]

Workaround is to add inverter as tcp/ip (with some make believe ip address) and not as serial. When integration is initializing, use the three dots and change to serial. Then restart Home Assistant That worked for me.

Reopen, because it is still a bug, even though I found a workaround

Just released 2024.09.3 which hopefully fixes this error.
