Does it provide pure sine wave power or modified sine wave.

not sure, it is in our home in Honduras and runs a complete 4K sq. ft. home with air conditioning and all appliances you would find in a home in America. It was hooked up by a contractor when we were not present but it comes on every time the power goes off which is often.

I don't have any idea. You would have to contact GENERAC for a technical answer.

Some electronic ignitions on the furnace won't work without a pure sine wave. Better check first.

I am a retired electrical engineer so I can tell you it is not necessary to scope the output of this inverter to tell you the output looks like crap as compared to a pure sign wave inverter. It is a modified square wave output that simulates a sign wave as close as possible. The only advantage of this inverter is it is cheap and has the ability to start inductive loads rather well because it can supply the necessary current needed to achieve motor starting. I use this inverter to run saws, drills, and a small air unit in my shop. I have to pure sign wave inverters that run my home because many electronic appliances require a pure sign wave. You can look up modified sign wave on the internet to see the difference in a modified sign wave and a pure sign wave. Hope this helps in your decision making.

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.

If you use a modified sine inverter with an led tv you will not like your picture. You should use a pure sine. Also your tv will last longer on a pure sine.Joe

I do not think so. Be careful with inverters of this type. They are called "modified sine wave inverters" And what you really need is termed a "True Sine Wave Inverter." A modified sine wave inverter delivers a digital wave form that over time will destroy your laptop. It also is very probable that it is what is causing your problems. A "True Sine Wave Inverter" produces a real waveform and also switches at 60HZ. It gives the same purity of,power as your electric company does. However these are more expensive then the modified sine wave models are. Most of those come with warnings not to use any devices that need chargers.. Examples of true sine wave inverters are made by Samlex, Xantrex, ( my two favorite producers ) and a few other companies.

This power supply is designed for providing a very clean sine wave power for sensitive computers and other electronics for a very short period. This power supply will not work well with a sump pump which needs more capacity an does not need a clean sine wave for power.

Pure sine wave is the best way to go. I've had modified sine before and while they do work for most things, induction motors and microwaves don't put out full power and are noisier. I bought a 2800 watt Magnum Energy pure sine wave and have never looked back.

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.

It is not a pure sine wave inverter. That being said, it will operate 90% of anything you would want to run with no problems.

AC or DC makes no difference as long as the amp rating and voltage rating are not exceeded. Ohm's Law doesn't care which it is in this application.

To answer your question, I just walked down to the basement and plugged my 48V Genssi power supply powering a DC fan into an APC BackUPS 500, pulled the input plug on the UPS (which causes the UPS to output a modified sine wave) and it had no effect on the operation of the power supply. I ran the fan from low speed to high, then plugged the UPS back into the wall to switch it back a pure sine, but I could detect no effect on the power supply. I hope that helps.

Modified Sine. So it's not as good as a pure Sine. Depends on the electronics you're trying to use. Laptop or PC should be fine. High end test equipment, medical devices, you would be better with pure sine.

As another said, it's because the inverter puts out a "Modified sine wave" where it's power isn't exactly the same as house power. If you have an electrical workers oscilloscope, you'd see the house power curve up to the max and drop down in a curve, any power inverters that aren't labeled "True sine wave" just put out pulses of power with it instantly jumping to max, staying on max for a few milliseconds, then turning off (with no curves). I don't know fully why the "buzzing" comes thru, but it is the inverters power (and I've seen that explained in power inverter manuals).

It should. The inverter is pretty robust, and a momentary surge into 1100-1200w should be fine. However, being that you are paying for a pure sine-wave inverter, rather than a much cheaper modified sine-wave, I would be sure that the simple on/off motor really is going to benefit from the clean AC power. I use modified wave inverters on plain simple motors (skil-saws), but electronically controlled, variable, clock timed devices, as well as all electronics get the better juice. The other consideration is that certain times, modified sine-wave inverters can shorten the life span of an electric motor. Might do a search on that subject, concerning motors in garage door openers. I tend to think these motors are just fine with modified sine-wave.

Yes with a 400 watt inverter...pure sinwave inverter preferably...but nonetheless an inverter
