What is the difference between a Pure Sine Wave Inverter & Modified Sine Wave Inverter?


Explore Electric is often asked by our customers what the difference is between a Pure Sine Wave inverters and a Modified Sine Wave inverters.  The main difference between them is that the Pure Sine Wave inverter produces a better and cleaner current. Because of this, they are also more expensive.

Modified Sine Wave inverters work well for many uses, and are the most economical. Pure Sine Wave inverters are more suited for items such as laptop computers, stereos, laser printers, specialized applications such as medical equipment, electrical devices with an internal computer, appliances with multi-stage timers, and variable speed or rechargeable tools.  If you wish to use those items with n power inverters, then choose a Pure Sine Wave inverter. If you mostly want to run lights, TVs, single speed tools, and the like, a Modified Sine Wave inverter is fine for your needs.


With a Pure Sine Wave inverter, the output voltage wave form is a very steady signal wave with very low harmonic distortion and clean power, much more like utility-supplied electricity.  Inductive loads like microwave ovens and motors run faster, quieter and cooler.  Pure Sine Wave Inverters reduce audible and electrical noise in fans, fluorescent lights, audio amplifiers, TVs, game consoles, and FAXs.
