Beginner looking for inverter for a weird setup
Hey, I'm looking into getting a solar setup with an inverter that's using the solar output directly first but supplementing it from the grid on the fly BUT it does not put electricity back to the grid. That is very important because here in the EU I'd have to get a permit and would be limited in many ways and possibly even taxed.
So I think it needs a hybrid inverter? But at this point I'm not planning on having batteries, maybe later but I'd like to have that as an option later.
Point is to use solar first like an off-grid, but supplemented from the grid live and just "waste" the excess solar production instead of sending it back to the grid.
What's the most reliable inverter brand or model that can do that (230V, I have 3x32A input from the grid broken down to about a dozen 16A breakers)?

Most bimodal inverters can do this. It is called grid zero or zero feed in. Even non-bimodal (no battery) system can do grid zero. they just need a consumption meter and configuration settings.
Then you do not want a bimodal (what you are calling hybrid). no batteries just get a grid tie inverter that can do grid zero like SolarEdge, or enphase and the consumption meter (standard now with solarEdge).
almost all solar installations use solar energy first. There is no wasting of the energy, you just are not going to collect it.
Also called "zero export" by some inverter manufactures.
