[Bug]: Configuration flow could not be loaded: {"message":"An invalid handler was specified

[iulianmitea]

Describe the issue

After you released huawai solar 1.5.3, I upgraded to si Core 2025.1.4, but the integration does not work, it gave me this message "Configuration flow could not be loaded: {"message":"An invalid handler was specified "}". the integration function in version 1.4.1 and core 2024.12.5., with 2 8 kw inverters connected via waier in Sdongle and the second 3 kw connected via wifi, no problems. I thought it was a conflict with Modbuss where I have a hitachi PDC mbuss via TCP, but after deleting it completely the message is the same
