trying to match a panel to a controller, need advice

Hi solar people,

A friend has bought a solar panel for camping and it's got a PWM controller on it. They need it to charge a couple USB devices and run a fridge that is 12v.

The panel specs are as best i can tell

output 18.5v @ 14.09a (it says its 260w so that maths out roughly)

i am looking at this controller that says

Specification: Item Type: MPPT Solar Charge Controller Material: PC Rated Discharge Current: 15A System Voltage: 12V, 24V (Self Adaption) Maximum PV Voltage (12V, 24V): 18V Solar Panel for 12V Battery, 36V Solar Panel for 24V Battery USB Output: 5V 2A Maximum Connection: Supports Bluetooth

Does this sound appropriate ? it doesn't seem to have a max input amperage (why do all these things use different words for the same thing :D i dont think 'solar input' is a real measurement but its simple)
