this is again where we need to know your house battery voltage and capacity to be nailed down before hammering out the solar charger needs..
400AH @ 12VDC * 0.4C = 160A (1920W) Charge Rate, To Obtain this you could run 4x50A SmartSolars, each with 2 panels at 500W (~40A)
200AH @ 24VDC * 0.4C = 80A (1920W) Charge Rate, To Obtain this you could run 2x50A SmartSolars, each with 4 panels at 1000W (~40A)
This is one of the things you gain on going to 24v, your dumping half the amps in for the same wattage, so you could have half the chargers.

Notice how the "Nominal PV Power" doubles when going from 12v to 24v, the controller supports both voltages but way more panels in 24v.
They do make chargers bigger than that, but prices reflect that.. and since you have stuff mounted on roof that could shade some panels I'd advise against trying to wire all that solar into a singular charge controller, put all the panels likely to be shaded by a roof vent or something on one controller and the rest on the other.. more controllers with less panels would cope with varying shade on roof better than less controllers
