Without a pure sine wave inverter like 1000watt Pure Sine Wave Inverter, most electronic devices work fine but before making a purchase, there are some things to think about. Electronics that use AC motors, like microwave ovens, compressors, and refrigerators are the primary category of devices that run more efficiently with a pure sine wave inverter.

Undesired interference and efficiency from the additional harmonics present in a modified sine wave are the two main issues. That means that at two things, a pure sine wave inverter is good: efficiently powering devices like radios that can suffer from interference and powering devices using the alternating current input without rectifying it first.

Is a Pure Sine Wave Inverter Needed?

To determine if you need a pure sine wave inverter, some useful questions to ask yourself include:

Is a motor needed in the appliance or device?

Is the device a delicate medical equipment piece?

Is a rectifier needed in the appliance or device?

Can a DC adapter power the device?
