Why Choose a Modified Sine Wave Inverter?

Power inverters provide a nifty solution for those who need to use electrical devices and appliances on the go. However, pure sine and top quality inverters don’t usually come cheap so you might want to save up a bit if you want to have them. Fortunately, there is a more affordable alternative to expensive inverters in the form of the modified sine wave inverter. This type of power inverter can get the job done, but without the high costs.

If you need to use electrical appliances off the grid, here are some of the reasons why you should consider choosing a modified sine wave inverter.


Modified sine wave inverters are usually less expensive than true or pure sine wave inverters. It is because the technology they use is more cost-effective to produce than the latter. Although they do not generate a perfect replica of AC true sine wave power, they are capable of providing a more affordable option that is perfectly suitable for many mobile power applications.

Ideal for equipment that runs on non-sinusoidal current

Before you buy an inverter, one of things you should do is determine if you really need a pure sine wave inverter or having a modified sine wave inverter would work just as well. If the appliance or equipment you want to use with the inverter is capable of running on non-sinusoidal current, which contains multiple sine waves of different frequencies, then you’re better off with a modified sine wave inverter.

A Quick Note

Take note, however, that not all electrical appliances and electronic devices may work with a modified sine wave inverter. For example, anything that uses an AC motor may not function properly when connected with this type of inverter. This includes refrigerators, microwave ovens, and compressors.

Delicate medical equipment, such as oxygen concentrators, devices that use thristors like laser printers and photocopiers, and those that use silicon-controlled rectifiers may also not be compatible with modified sine wave inverters. Similarly, lighting equipment that utilises electronic ballasts may perform poorly and should be used with a pure sine wave inverter instead.
