Can I connect my charge controller to my panel?

My mppt charge controller is in the same cabinet, and is wired directly to the output of the converter, which is a straight run to the batteries. It's been between my two 75 watt panels and the batteries for years, and has taken great care of them. Unless I become a fulltimer and need to eek out every little ounce of power, I will stick with this tried and true method. I do have switches and fuses in between the controller and panels, and batteries.
