Is this a modified sine wave inverter or a true sine wave inverter? Two other websites are saying this inverter is "true-power". What is "true-power"?

I know you looked at there website, try to find the contact number. I do not know either. I have two and so far they work good, can't run an air conditioner without issues, I think I need more amps to get the 10,000 (so they say) watts. sorry I can't help much.

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

The SMART1500LCDT has a PWM sine wave (Pulse-width modulation), not a pure sine wave. However, Tripp Lite carries many other 1500VA UPSs with a pure sine wave output. Also, please know that not all computers and electronics require a pure sine wave. For assistance in choosing the right product for your needs and if you have any additional questions, please reach to our Chicago-based Presales Applications Team at (773)869.1773 or presaleshelp@tripplite.com.

I cannot speak to the inverter issue but if outputs 60hz 1120v current it should work fine. The power setting are extremely consistent if set on temperature they are within two to three degrees of the indicated temperature almost always on the high side(i.e. if set at 80 degrees F the actual temp with my unit will be 82 degrees. Overall it seems to be of high quality.

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.

This was a major question for me before I bought the inverter. The unit does not have a power switch, and the instruction booklet specifies that when no AC load is connected, battery drain is less than .4 A. I was using the inverter in a fire lookout with solar electric power. The solar regulator had a display that include source and load amperage at the .1 level, and I did several types of testing to see whether there was any apparent drain with no load. I never saw any current from the batteries indicated unless I had something charging. I used a Surface tablet PC, often for hours a day, and charge my camera batteries repeatedly. The inverter performed like a champ the whole time. I hope that answers your question. In case you're interested, the published conversion efficiency (12 VDC -&gt; 110 VAC) is 85%. That's impressive!

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.

Been using it non stop for a year (i.e., has been connected to power and running computers and printer etc.) have not had any problems. And yes it is a true sine wave. Laser printer and NuWave PIC work fine on it.

No, buy a solar charger, and fine a true or pure sine wave power inverter that suits your needs

this inverter is a under powered inverter. go with a aims inverter!! I picked up a pure sine wave aims inverter and have been loving it.

Mine is the 500 watt unit - but it DOES shut off below 11 volts or above 14.5 volts. With a marine battery that might be enough to "recover" overnight and therefore acceptable. Do be aware that this unit, which I like very much and has worked flawlessly for quite a while, IS NOT a TRUE SINE WAVE type and for my computers etc. that do require True/Pure Sine Wave power; I purchased an additional, different inverter as well.

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.

Modified sine wave. This inverter will not perform as advertised. Very weak.

This is a full DC inverter system, just like others. It is a low cost system with standard efficiency ratings. We also have other inverters rated as high as 22 SEER at much higher prices.

Yes, it outputs 60 Hz but DOES NOT output a sine wave. Small inverters of this type put out what is sometimes called "dirty" 60Hz power, which is perfectly fine for most (modern) digital electronics, incandescent lights, and SOME motors. It is not good for other kinds of motors some fluorescent lights, and many analog audio systems (you'll hear a hum). I'm afraid I don't know which motors are OK and which are not.

No, the inverter is Modifyed, we can supply a pure syne wave for an additional $150.00 Thanks, OG Solar

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.

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
