[Bug]: Deprecation Warnings and State Class Issues with huawei_solar Integration

[wpformation]

Describe the issue

First of all, thank you for your excellent work on the huawei_solar integration! It has been incredibly useful in my Home Assistant setup. I’ve encountered some warnings in my logs, and I wanted to bring them to your attention so the integration can remain compatible with future Home Assistant versions.

Here are the warnings:
The integration is using a deprecated constant, POWER_VOLT_AMPERE_REACTIVE. It should be replaced with UnitOfReactivePower.VOLT_AMPERE_REACTIVE.
I am also seeing multiple warnings about mismatches between state_class and device_class in various sensors.
There are also warnings about invalid units of measurement:
