There are many differences between pure (true) and modified sine wave inverters. Knowing which to choose will depend on what will be plugged into the inverter. When using sensitive electronics or medical devices it is recommended to use pure sine wave inverters. Because the harmonic distortion is higher in modified sine wave inverters they tend to be less efficient and may cause a buzzing noise from some audio devices and appliances.
Modified sine wave inverters are generally better with products that run on batteries. The power from modified inverters tends to be choppy and not consistent and often “square” waves. For this reason, they will do better in industrial situations. Modified sine wave inverters are generally more cost effective than pure sine wave inverters.
