Is this a pure sine wave or a modified sine wave

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.

It takes 12 volt DC input and turns it into pure sine wave 115 volt AC. It only works between 10.5 and 14 volts input.

Says it is full sine but I couldn't tell because as soon as I tried it, it quit working before it even started.

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.

The only way to get a pure sine wave is to have a generator or plug into your house

I have actually tested this but not with UPS's that have Pure sine wave. When I tested this with cheaper ups's it resulted in damage to the second inline ups. Also both batteries drain at the same rate so does not give you double the time left. There are ups's that are actually made to be run in series but those are expensive as we use them in our office at work. Those are made different then these.

I used a 'scope to fine adjust the frequency and seem to recall it was close to a pure sine wave, quite clean power. It powers all our electronic equipment without a problem. I adjusted the frequency using the peaks of the waves to stop our UPS's from complaining

Hi Gary,The Nature Power Solar Home and RV Kit with 40 Watt Solar Panel, 1800 Watt Inverter and 60 Amp Battery has a modified sine wave inverter. Please feel free to contact Earthtech Products if you have any additional questions.Best regards,Earthtech Products Customer Service

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

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.

I am not sure I understand your question. This unit is an inverter and produces a modified sine wave output at the stated voltage range. It normally uses commercial sine wave AC current to drive the inverter, but if you want to use use non commercial power like a portable generator or newer portable inverter, there is no reason it would not work but I have never used it in the arrangement. Some generators and inverters have 12 volt outputs anyway but not at 20-30 or 50 amp rating like this unit can supply. If you plan to use an inverter to drive this inverter, you can expect some additional noise in some sensitive devices like a nearby AM radio. I gape this answers your question.

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 pure sine wave tech. so they should be the same as utility power. The one I have does not do a very good job of regulating voltage though with loads above 700 watts. It will take a dip of up to 30 volts depending on the load and then come back to normal voltage. Good heavy cables were use too.

Negative, this is a modified wave inverter. They are designed to emulate pure sine waves, but the pure sine inverter from power bright is a bit more expensive and can be found on amazon. Just search pure sine power bright.

I purchased one about a year ago. I returned it because when I connected my iPad to it, the iPad went crazy. I was using the stock power supply that came with it. I tested this several times before I returned it. To answer your question, it is probably NOT a pure sine wave inverter. I ended up getting a Xantrex Prowatt pure sine wave inverter.

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

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.
