Does converting a DC power sorce to an AC power supply change voltage levels? If so, how? I'm building a prototype high temp desert tent. I want to use a solar panel that happens to produce DC current to a cooling system that uses AC power. Specs: Solar panel -32 Watt, 1.94 Imp, 16.5 Vmp Air cooler -120 Volts/ 60 Hz Unit operates at 21 Watts I'm having issues understanding voltage.
