Does SolaX X1/X3 Hybrid (G3/G4) work locally with Home Assistant?

Yes, according to the public sources: the HA core integration “SolaX Power” and the HACS integration “SolaX Inverter Modbus” talk to it over the local network and expose settable entities, not only sensors; evcc supports it locally and lets evcc control it.

Firmware updates can open or close local access — check the integration's own page before you buy, and your installer before software changes export limits or charges a battery from the grid.
