The Advanced Mini-Controller along with our 5A Power Supply can run up to 6 strings of our 24 Light RGB strings (144 lights total).  If you want to go farther, you can connect another 5A Power Supply (through a Power Injection T), to another set of 6 strings.  You can do this 2 times for a total of 432 lights (if you wanted to max it out you could add a final 1.5A Power Supply with Power Injector T and 2 more light strings for a total of 480L).   See the diagram:
