Little Gray Box - How it Works

The Power unit reduces the amount of power drawn from the utility by temporarily storing otherwise wasted electricity from the induction motors in your home. Then when the motor needs more power it is fed back from our units directly to the motor, which reduces the wasted electric, which lower electric bills.
It is not a storage battery but a short term buffer between the power company and your home electrical system.
(Some examples of the offending motors are Air Conditioning units, refrigerators, freezers, washers, dryers, dishwashers, pool pumps, vacuum cleaners, furnace blower motors, heat pumps, fans etc.)
Electric motors as a rule don't use all of the electricity that they draw from the power source. they waste a good deal of power in the form of over producing the magnetic field that turns the motor.

Our power boxes helps to reduce this process, which in turn reduces the amount of electric used to run each motor in your home.
This whole process is called power factor optimization.
