Devices That Might Be Damaged by a Modified Sine Wave Inverter

• Appliances like refrigerators, microwaves, and compressors that use AC motors won’t run as efficiently on a modified sine wave as they would on a pure sine wave.

• Delicate medical equipment, for instance, if you use a CPAP to help correct apneas when you’re asleep, you’re going to be better off with a pure sine wave inverter.

• Devices that use thyristors like laser printers and photocopiers.

• Devices that use silicon-controlled rectifiers.

• Lighting that makes use of electronic ballasts, like many fluorescent lights.
