It is efficient. 600 watts for 8000 btu's is excellent. Compare that to a roof 13500 btu air conditioner which draws between 1300 and 1900 watt.
600/8000 = 0.075 or about 46 amps @ 12 volts or 174 btu's per amp
1300/13500 = 0.096 or about 130 amps @ 12 volts or 104 btu's per amp
1900/13500 = 0.141 or about 190 amps @ 12 volts or 71 btu's per amp
The amps calculations on the last two lines are allowing for inverter inefficiencies, but even without that the 12 volt unit more efficient. The two lines are also based on actual measurements that I've made.
Point taken.
Yet, it is efficient at emptying your pocketbook :) Out of curiousity, do you think this would last about the same, longer, or less time than a conventional unit?
