Sine Wave Inverter Using 555 Timer

Sine wave inverters are more efficient than square wave inverters, when it comes to the conversion of DC to AC. This ensures that the power loss is minimized, due to greater efficiency. As a consequence, your electricity bill does not shoot up. This is an immediate benefit of using a sine wave inverter.

The red line in the figure represents a sine wave while the green one shows the current alternating in a square wave. You can see the smooth change-over of a sine wave. This is the same kind of power that the grid supplies. Since your inverter is going to be a substitute for grid power, it is important for the kind of power be the same.
