Hi,
My Blue Sky does a maximum of 17 amps @ 14.x volts. It gets warm enough that you would not wish to leave your hand on it for very long. It does not have a cooling fan. Output is a maximum of 224 watts.
Fried controller and eggs is not a "breakfast of champions".

This is the OP coming back again. Since it appears no one makes a waterproof controller (larger than 4.5A), my next idea is to mount the controller under the batteries in a waterproof box like the below one from Home Depot.
Home Depot 12" x 12" x 6" waterproof junction box.
I'm in Alaska so I don't have the southwests' hot temperatures and I'd mount it under the battery boxes in the shade. I can easily seal where the wires go in and out of the box. How much heat does a controller for 2 - 300 watts put off - do I have to worry about it?
