This is not it. Not only is there a microinverter and a breaker there to address that issue, but my understanding as a layman is the load in the circuit is down to how much you’re drawing (i.e. if you’re generating 1200 behind the microinverter and pulling 1500 you’re pulling 1500 through the circuit, not 2700).
The bigger fire hazard here is the battery many of these come with for storage, honestly.
That’s not to say there isn’t a bit of a risk. You need to be careful if you need to do something in the installation that you disable both the grid breaker and the microinverter. Otherwise it’s entirely possible for the grid safety to blow and the inverter to keep pumping power into your house. But as the previous poster says, there’s a reason these are legal to install in apartments all over Europe, and it’s not just European grids being set for higher amps. FWIW, most of these kits come with 800W max out. My understanding is they’re perfectly fine to use as a cost mitigation and they’ll keep your fridge going in a blackout but no, they won’t be constantly tripping your fuse.
