Prepping your house for solar:
1)install a breaker panel AHEAD of your existing main panel. This panel will be used to feed utility power to your (future) inverters when batteries are low, and you'll put large loads on here that you don't want on your inverters such as your HVAC heat strips.
2)Most conventional heatpump systems power the air handler with a large wire that a)supplies the blower, b)supplies power a small transformer, c)supplies 10kw to heat strips. Separate the heat strips from this and move them to the aforementioned new breaker box.
3)If you have an electric hot water heater, swap the 4500w heating elements with 1500w heating elements.
4)If your HVAC has hiccuped or you might be thinking of replacing it soon, consider a mitsubishi ducted minisplit. It's a one for one swap with your existing air handler. If you don't want to get a new HVAC system, get a soft starter for your compressor.

5)get a whole house kWh meter such as Emporia Vue. Use this to identify vampire drain and also to know what the maxium pull on your house is.
It's best to make some small changes and add instrumentation to your house. Establish some history and THEN you can make an informed decision on exactly what your solar production and inverter needs are.
Three primary things you want to know:
1)kWh per day of usage on the toughest day. (solar production)
2)kW usage when everything is running at the same time (inveter sizing)
3)kWh usage from sundown until sunup (battery sizing).
