If you are using a 24V battery bank, then the Renogy Rover Li 40A controller will handle up to 1040W.
Using the calculations given previously by bupkis, you can stay within the voltage limits of the controller by using two sets of 2 series-connected panels, in parallel. This is how you would connect the 4 panels you plan to install eventually. As bupkis said, there is no easy way to use 3 panels.
So long as your battery bank can accept a charge current up to 40A, this is how you would use 4 275W panels (1100W vs. the 1040W specification should not be an issue.)
Here is a Renogy picture showing actually 8 panels. Your diagram would be basically the same - just cut out the middle 4 panels.
either is fine, I think parallel is a tad better due to less transforming power loss from higher to battery voltage and shade issue with series. series does keep the input amps lower and therefore less voltage drop over the same size wire.
