240w is 15 amps Isc, so you would need a 20 amp controller. You are supposed to leave some margin above the expected panel amps.
IMO get the panels first and then get the controller in the right size to match what panels you actually buy. (Might get a deal on a pair of 160s, who knows?)
BLF13, normally I'd agree with you, but in this case my selection of waterproof controllers is so very limited, I have to find the largest one and then buy the panels it can handle.
