is thei unit pure sine wave or modified sine wave?

Hi Glen ,This is not a pure sine inverter.Please read the additional facts below.The inverter have three Power Index1.Marked power2.Peak Power3.Long time working powerNormal Output Power means the Peak power.Peak power is the moment Maximum power when we start the electric equipment.this peak power might be 1.5-3 timesDifferent electric equipment have different peak power. We need to know the rated power (Average Power) before we choose the Electric power supply ( like the inverter or battery). The power supply is 1.5-2 times. Electric equipment power,special electric equipment will need 3 times of Electric Power.General Average Power is counted according to 72% of peak power.This accounting methods usually is for small power electric equipment.

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

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 would get a 3000 pure sine GP-SW3000-12. I can't find the 3000HD one to be UL listed.

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.

No this is a modified sine wave inverter----we have had trouble with this inverter being able to work with one type of cordless tool charger-----so we purchased two different brands of pure sine wave inverters to see if this would in fact eliminate our problem-----it did not so we went back to this inverter and have not had any other issues with it not running any tools with the exception of the one----and that was solved by putting 12 V vehicle chargers in all the service trucks-----we run over 140 of these and they have been bullet proof---1 failure in 140 plus units in service

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

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

I got the below from Tom's Hardware from someone who asked the same question and the answer they received from CyberPower: "I received the following answer from Pietro Boggio, Senior Technical Support Specialist at CyberPower: "No digitally created wave can be a true mathematically curved analog wave. But the number of digital steps used to create the wave can be great enough that the electronics used in even the highest efficiency computer power supplies are unable to distinguish them from an analog wave. The total harmonic distortion of the output on battery is under 2% which means the output of the UPS is closer to a mathematically ideal analog wave than the powercoming out most peoples walls. "These units were created specifically for the needs of computer users with Active PFC power supplies. We put PFC in the model name to highlight the fact that these units are compatible with Active PFC Power Supplies." I can tell you I have the CyberPower CP1000PFCLCD PFC Sinewave UPS 1000VA 600W PFC Compatible Mini-Tower and I've had zero problems with it, my power has gone off several times since I've owned the unit and I have lots of sensitive equipment plugged into it.

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.

It will verify your voltage but not your sine wave. Are you trying to measure frequency or peak waves?

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.

The unit has high-temperature safety shutdown, low-voltage shutoff and overload protection. From the manual: The inverter produces a "modified sine wave." The modified sine wave is suitable for most AC powered appliances and personal electronic devices.

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.

This inverter is a modified sine wave unit. I will tell you this: I live in a motorhome with a small 400 watt system and use the Pw2300 and my main solar system is 600 watts and I use the pw2300. In other words buy it, for the price and the usage you will get out of it it will pay you back 10 fold.. Also the wireless remote is better than false teeth works amazing.. Hope this helps..

It is my understanding that it is NOT a pure sine wave. I do run a HDTV and Blu Ray player with it and have had no issues

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

Despite if they are the same, The only thing I guess that academic bundle doesn't give is this (Audio editing and manipulation including pitch correction, pitch shifting, harmonization, time-stretching, beat-detection & slicing, audio warping and standard audio manipulation) &lt;--- that is what the Image Line Softwate Bundel gives you besides the academic one. As long as that description shows :)
