Does it provide modified or true sine wave AC output?

Neither, it's a defective product. It provides nothing. You have been warned. Don't make my mistake by buying this unit.

A small inverter may do the trick but be sure that you have a return option if there is a problem. Most inverters produce square wave A/C (not sine wave) and may not work with some electronic devices. A 100 Watt unit may do but 200 Watts is better. Plan on spending $20 to $40 for one. Another option is a portable power supply with a built-in inverter (the kind with jumper cables).

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.

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

It's not a "Pure Sine Wave" - those are expensive. This one is a "Modified Sine Wave" - a square wave in other words. it didn't interfere with my car radio, and didn't cause any radio noise in a small tabletop 120V radio that I ran out of this inverter.

It does, yes. According to Synology, AC Input Power Voltage is rated at 100V to 240V AC at 50/60 HZ, Single Phase.

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.

Enphase microinverters are designed to comply with IEEE 1547, Clauses 4.3.3 and 5.1.6. The spec for AC sine wave total harmonic distortion is 5% max (3% typical), measured IAW IEEE1547.1, Clause 5.11. This spec is further characterized in terms of Total "Rated" Current" Distortion (typically 2.0%), and Total "Demand" Current" Distortion (typically 1.3%).

Peetty sure it is modified. Dont know ecatly what true sine is. Goes to the manifactures web page. They explain

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.

This is a modified sine inverter, as such there is a distortion which you can hear when you use this with some devices such as box fans.

No, see other responses. Not quite Pure Sine Wave. Apple products won't charge from this inverter. Mine blew out a control IC to the output stage after the 90 warrant expired.

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.

No. But it will do anti islanding. If it does not "see" an AC sine wave on the output pug it will not turn ON.

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.

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.

We haven't run it with such an inverter, but we did look at the circuitry inside when evaluating it, and it shouldn't need a pure sine-wave. In fact, it only pulls power at the peaks of the sine wave (it has around a 0.7 power factor), and will actually run with an appropriate high-voltage DC input instead of AC. So it shouldn't care if your inverter is "modified-sine-wave". Your inverter, however, may care that the supply only pulls power during part of the cycle, and you may therefore need an inverter with a higher peak output power/current than you were expecting.
