At 12V, your total maximum power input would be 800W giving 67 amps of current. This would mean 80amps capacity plus in the controller. For a large input like this, you are better consulting the panel/wind generator suppliers- or better still the manufacturer and take their recommendation. Using one of their own controllers might then guarantee the systems performance better.
Also consider the type of controller, and the battery bank capacity- and type of battery chemistry you are using.

The type of controller required for both solar and wind generators is the same, it shunts any excess power to prevent overcharging of the battery. Thus one 100Amp controller should be sufficient.
