Pure Sine Wave vs Modified Sine Wave Inverter: Which Do You Need For Your Rooftop Solar

Have you ever consider that which sine wave output of PV inverter is best for your rooftop solar? In general, there are two major types solar power pure sine wave inverter or with modified sine wave inverter. What is the differences and which type suits to your rooftop solar? In this article, I will explore further about these two types of sine wave inverter.

What is a Pure Sine Wave Inverter?

Pure sine wave inverter is device that converts the direct current (DC) electricity from solar panels or batteries into alternating current (AC) electricity that has a smooth and continuous waveform which is similar to the electricity from the grid.  A solar inverter with pure sine wave output can also reduce the power losses and distortions that occur during the conversion and transmission.

What is a Modified Sine Wave Inverter?

Unlike pure sine wave inverter, the waveform output of modified sine wave is stepped and square. A modified sine wave output is a simpler and cheaper form of AC electricity, but it may not be compatible with some appliances and devices, especially those that are sensitive to the quality and stability of the power supply. A solar inverter with modified sine wave output increase the power losses and distortions that occur during the conversion and transmission of electricity from DC to AC.

Pure Sine Wave vs Modified Sine Wave Inverter: How to Choose?

Each type of inverter has its own advantages and disadvantages. When deciding to buy between pure sine wave inverter and modified wave inverter, you may think about the following factors:

Type of Load you want to power

When the load require a pure sine wave to function properly, such as sensitive electronics, medical equipment, audio systems, and induction motors. A modified sine wave inverter may cause interference, distortion, damage, or reduced performance to these devices.

The quality of the output

A pure sine wave inverter produces a smooth and continuous waveform that matches the grid power. It provides clean and stable power for any kind of load. A modified sine wave inverter produces a choppy and square waveform that approximates the grid power.

Cost and efficiency

A pure sine wave inverter is more expensive than a modified sine wave inverter, as it has more complex circuitry and components. However, it also has higher conversion efficiency and lower power loss, which can save you money in the long run. A modified sine wave inverter is cheaper than a pure sine wave inverter, as it has simpler circuitry and components. However, it also has lower conversion efficiency and higher power loss, which can cost you more in the long run.
