Pulled off the covers from the back of the Suitcase 100w kit. The wiring will not handle any increased load. It's .15tmm equivalent to 15awg. The alligator clamps have 12awg going to the battery. I made up a 10awg extension of 15 feet for the suitcase.
Based on my findings, I will have to go with a separate controller. I did check and no room in the battery compartment for a controller. So I will probably make up another battery connector setup of 10awg with a fuse.
