A sine wave inverter is an electrical device that converts DC (direct current) power from a battery or renewable energy source into AC (an alternating current) power to power electrical devices and appliances.


The working of these inverters involves several stages:

1. Rectification

A rectifier circuit converts the DC input voltage into a pulsed DC signal.

2. Filtering

The pulsed DC signal is filtered to produce a smooth DC voltage.

3. Pulse Width Modulation (PWM)

The smooth DC voltage is then converted into a train of pulses using a PWM circuit.

4. Inverter

The train of pulses is then passed through an inverter circuit to produce an AC output voltage closely resembling a sine wave.

The output of a sine wave inverter is a clean, smooth, and stable AC voltage similar in quality to the power supplied by utility companies. This makes it ideal for powering sensitive electrical devices such as computers, televisions, and other electronics.

Why are sine wave inverters so popular among homeowners?

Here are five reasons why these inverters have become so popular:

Purest Sine Wave Output

They produce a pure sine wave output, identical to the electricity supplied by utility companies. This output is clean, stable, and compatible with all electrical appliances and electronics.

Improved Performance

They exhibit improved performance compared to modified inverters. This is because pure sine wave output is smoother and more stable, reducing the risk of damage to sensitive electrical devices and appliances.

Energy Efficiency

These inverters are energy efficient and use less energy to produce the same output as modified inverters. This results in lower energy bills and a more sustainable energy source.


They are versatile, and you can use them for running various applications in homes, offices, RVs, boats, and even off-grid solar systems.


They are made from high-quality materials, making them durable and resistant to harsh environments. 

Thus, sine wave inverters provide clean, stable, and efficient energy compatible with all electrical appliances and electronics. If you are a homeowner looking for the finest quality inverters, your search ends at Exeltech.
