Most AC products run fine on Modified Sine Wave inverters. True Sine Wave inverters are about two to three times as expensive per watt due to having more sophisticated design and manufacturing requirements, and more expensive components. As a result, most people prefer to use Modified Sine Wave inverters if their applications allow it. Manufactuers do not guarantee that your AC application will work with an Modifed Sine Wave inverter, and we advise our customers to check with the manufacturer of your AC device as to whether or not it will run with a Modified Sine Wave inverter or whether you should purchase a True Sine Wave product for your application.
