What kind of wave does it put out? Sine wave or square wave?

All generators Champion makes use a true sine wave. It does not use square or modified sine waves. When it has a lot of THD those waves grow erratic spikes on them but they still maintain their waveform

My husband does not remember, but it is probably a square wave - but we use it as a backup to a solar system and it would be corrected for that by the type of inverter we have on the system. The generator will power our whole 1200 sq ft house, including 3 split air conditioning units (trane brand). We have no problems with our electronics or ceiling fans when running the generator - but our inverter would take care of a problem.

You have the choice of Low Oscillate, or Still, & High Oscillate & Still. The only thing I wish it had was a remote.... (sorry, that's the cozy lazy me responding) ;)I hope I answered your question, if you purchase this item, I believe you will enjoy it.Cherie J.

Brian, the PV2000FC maintains a PWM sine wave output voltage of 120 V AC (+/- 5%). If you are looking for a pure sine wave inverter, I would recommend our APS2012SW (ASIN: B006R64SUE), a 2000W PowerVerter with Pure Sine Wave Output.

I am not sure what you mean. It will put out around 2 v p, 1.5v rms sign wave at 1Khz. It can only give you about 44mv into 20 ohms. it will give you 3.4v square wave at 1khz.

Fridge doesn't require an expensive pure sine wave inverter, run it off a 2KW cheap inverter. You're overloading this inverter on startup with your fridge. I've run all my fridges/freezers and even computers for years off cheap inverters. TV's and other devices that sing from from the non-pure sine wave need a better inverter.

Hello, I purchaced to replace a cheape one that I had. Yes, It makes alot of noise, and bleeds over to FM radio's plugged in to it. I do not think it is a true full sine wave, I think it is a modified, wish is why it does that. Other than that, it works great. i lvoe it a great deal. Bob....

well, because is for relaxing, the music is low volume or with headphones but is from an outside device (TV or cell phone) no through the device itself. as per my understanding the sound from the device was not the best but I don't recall that the sound coming from the device change the pace of the wave effects... thanks for point it out I will check it out, but any how as it is the wave pace is perfect.

Answer from Wikipedia: A power inverter device which produces a smooth sinusoidal AC waveform is referred to as a sine wave inverter. To more clearly distinguish from "modified sine wave" or other creative terminology, the phrase pure sine wave inverter is sometimes used. The terminology "modified sine wave" has come into use and refers to an output waveform that is a useful rough approximation of a sine wave for power translation purposes.

The "pure sine wave" inverter can help running some things and eliminate a sound "Buzz" that can come from the cheaper "modified sine wave" inverters running radios & such. However, I'm not sure for a laptop that it will make that big a difference since the power is converted back to DC anyway (where it almost seems funny to take DC power, change it to AC just to go back to DC).

While it is true that a modified sine wave inverter may damage certain types of electronic devices, that's really more of the exception than the rule. There are two different things that you need to be concerned about: appliances that use AC motors and certain classes of delicate medical equipment. If your electronics don't fall into either of those categories, then you're good to go with a modified sine wave inverter - and you saved a bunch of money to boot. reference to above information. http://cartech.about.com/od/Power/f/Will-A-Modified-Sine-Wave-Inverter-Damage-My-Electronics.htm While it is true that a modified sine wave inverter may damage certain types of electronic devices, that's really more of the exception than the rule.

I have this since Jan 2012 and I work fixing UPS, I have all the equipment to test how pure the sine wave is and let me tell you! I have put on my fluke dual input at the same time utility and this and I would say the output of this UPS is actually more clean then the actual utility I would take pictures if anyone wants too see both in comparison.

When I purchased mine I got the answer to that in the literature that it came with as a modified Sine wave. However unless you are using this for medical physics the difference between the two is minimal. I hope that helps. Mine has worked fine for running a small refrigerator and TV while we camp.

It makes normal mouse sounds. But if you're looking to open it up to dampen the sound, this uses the square/cubic switches which you can't silence.

The output is a modified sine wave, though I don't know what it looks like. I picture it being a pixellated version of the real thing, with an unknown number of successive approximations to the sinusoid (like, step functions rising to .3, .5, .7, 1.0, then down again). I have used the unit to feed into the external power supply to my MS Surface pro, and it worked fine for the last two summers on a fire lookout. As I remember, sometimes it appeared not be charging the batteries in the Surface, but then, later, they would be charged. That might have been a spurious interpretation by the power monitor in the computer. Anyway, it was an excellent solution for back-country use.

Square. There is a heavier duty model called the e4. Both are excellent. Get whichever your application requires.

modified sine wave.....i use mine to run the washer and dryer , it works fine for that
