If your usage is only 3 months a year at 9 hours a day, buying an inverter would not make commercial sense. 9 x 90 = 810 hrs a year, Do the math.So according to the post I should be able to recover the initial investment in about 5 years right..
that seems like a pretty good deal factoring in the added advantages of super fast cooling and quietness
