This is a difficult question to answer. I am not sure about the context of what you are asking.
Will this be grid connected or off grid? If on grid, then of course there will be times that the fault current will be referenced to the grid.
The Quattro has an overload rating - check the datasheet, but you can also have an instantaneous fault current a lot more than this, maybe it will be enough to drop a circuit breaker. It also depends upon the response curve of the circuit breaker you are using. The Quattro will shut down if current is too much for it and maybe circuit breakers will not react in a very short time.
Use appropriate circuit breakers for the wiring of each circuit. Your electrician should be able to advise you.
