30a is ok for 450w mounted flat. Not wimpy at all. Leaves a little room for cold ambient. It would not leave proper margin for cold ambient with aimed 450w at high noon where it would be close to 30a. The controller will warm up too much if you go over its 30a rating for very long. Cloud effect short times are ok.
