Watts: Power is the amount of work done in a specific amount of time. The unit used to express power is watts which is a function of both current and voltage.

Kilowatt Hours: watts divided by 1000. One kilowatt = 1000 watts.

Example, a window air conditioner that operates on 120 volts at 12 amps can be calculated as 120V * 12A = 1440 Watts.

The transition of DC to AC is called an inversion, while the less common AC and DC transition is called a conversion. Three types of inverters from best and most expensive and complex to the most basic least expensive.

  1. Pure Sine Wave
  2. Modified Sine Wave
  3. Square Wave

A modified sine wave in most situations is as good as a pure sine wave and has energy saving characteristics. The square wave inverter is considered the most affordable, simple, and compact.
