Just check the spec sheet for the panel you have installed and on the controller. I'm guessing it's putting out about 10A at approx. 23V. So if you wire all 4 panels in series you'd have a 92V 10A total output. Depending on the maximum voltage for your controller you will likely be fine, but you really need to check the specs on the panels and on the controller to be sure. The 10 gauge wire should be fine for that current rating, assuming you wire them in series.
