Additional Context

No response

Reproduce startup with Home Assistant 2026.9.2 and solaredge-modbus-multi v4.0.0, then inspect the integration-loading error reported at helpers/translation.py:223 for solaredge_modbus_multi. Done means the integration loads normally at startup and provides the expected Modbus data.
