Total Harmonic Distortion

Champion portable generators will output an industry standard total harmonic distortion (THD) rating of about 12%-20% depending on load applied. They will produce a sine wave, not a modified or square wave. This is perfectly acceptable for running common commodities found in your home such as TVs, computers, your appliances, etc.
THD is a measure of the deviation of a sine wave from a "perfect" sine wave. All electricity, including line electricity, has measurable THD.
If you have a specific item that requires less than 3% THD such as a UPS style battery backup, a pellet stove, or high efficiency furnace control board, we recommend purchasing a Champion Inverter Generator (sizes from 2000W to 11,000W); Champion Open Frame Inverter (sizes from 4250W to 9000W) or a Champion Home Standby Generator (range from 8.5KW to 22KW); all units provide less than 3% THD.
Please consult your specific appliance manufacturer to determine if the appliance requires low THD (less than 3%) to operate properly.
