Switzerland: solar panels, power inverter, power management: any recomendations?

Dear community,

we have an old house, which was built in 1939 in Winterthur, Switzerland. In the coming weeks, we will get some solar panels installed. I do not yet have the offer of our installation partner, but I assume there is not much choice in hardware.
If there are some options, what do I need to look out for in regard to integration into home assistant?

  • Are there any power inverters common in Switzerland, that would directly integrate into HomeAssisstant? Or would you recommend to use a Shelly anyway?
  • What is important, when thinking about power management? I would like to use as much of the generated power myself, instead of sending it to the network. Do you do this with HomeAssistant or with some application provided by the power inverter manufacturer?
    – We do have a heat-pump-water-heater.
    – As the city will turn off the gas supply in some years, I will probably get a heat pump for heating the house as well.
    – Sooner or later, we will get an electric car, that should get the rest of the solar powered energy - if there is no washing maschine running, cooking, heat pump running, …

Any recommendations, feedback and hints are very much appreciated.
