What is a DC to AC Sine Wave Inverter?

An inverter is a power adaptor. Sine wave inverters convert DC to AC power with a sine wave output, which resembles the power supplied by the grid. 

Inverters are designed to convert power with minimised heat generation that results in reduced energy loss during the conversion process.  

One of the biggest advantages of using AC is that it is easier to convert the voltage of any current, making high-voltage transmissions feasible and cost-effective. For this reason, AC power is used for grid service or mains because it is more practical for long distance transmission.

If you have a household solar system (PV system), battery-powered mobile/marine vehicles, uninterruptible power supply (UPS) or battery setup, your inverter plays a vital role in converting DC power harnessed by any of these devices into AC power. The converted AC power can then be used for your appliances, electronic gadgets, machines, and sensitive equipment.  

Pure Sine Wave Vs. Modified Sine Wave Inverters 

The most common differences between these two inverters are cost and efficiency. Pure sine wave inverters have complex circuitry that enable them to generate a clear and smooth waveform, thus the more expensive option. Modified sine wave inverters, however, have simpler designs, thereby making them affordable.  

Pure sine wave inverters give the true sine wave forms with smooth curved peaks and trenches. These waves are akin to that of the grid’s actual sine waves, which produce a quieter, more refined power delivery. This will work on all kinds of electronics including sensitive equipment, such as medical devices, laptops, and televisions.  

Modified sine waves are “rough” with small gaps in between the waves that look like a stair-step square pattern. These waves are functional but provide lower quality electricity that may give off a humming noise while in use. The unrefined waves can negatively impact delicate appliances, so this inverter type is more suitable for gadgets that run with a motor, such as power tools, some kitchen tools, water pumps, old tube (CTR-type) TVs, etc.
