huawei_solar: [Bug]: Unable to connect via serial on 1.2.0b5 1.1.6 is working

Describe the issue

Upgrading to 1.2.0b5 cause connectivity issues over serial. Tried to complete remove and reinstall the integration, but then I’m unble to setup because huawei_solar.exceptions.ReadException: Failed to read register 43006 after 6 tries

added diagnostics file from 1.1.6

Bescribe your Huawei Solar Setup

Inverter Type: SUN2000-4.6KTL-L1 Inverter Firmware version: V200R001C00SPC125 SDongle present: no Power meter present: single phase Battery: LUNA2000 10kWh Battery Firmware version: V100R002C00SPC116

How do you connect to the inverter?

Over serial, with a serial-to-USB stick
