I'm gonna put the 185 in our neighborhood Christmas parade this year and have some questions on the best, and safest, way to power the lights. I'm wondering if I can use a 12v power inverter to run 3-5 sets of ALL LED lights, and one inflatable? If the power inverter is safe to use, any recommendations on model? I'll need to check what the inflatable pulls in amps, but with the LED lights a 500w should cover it(but may go bigger for future use)? Final question is which type of power cord. Most of the larger wattage inverters use alligator clamps, which make me a bit nervous as far as sparking in the bilge. My accessory outlet would be the optimal choice, right? Any thoughts would help.
