Is this a quasi-sine wave inverter?

Sorry, I have no idea. I was only interested in running some Christmas Tree lights in a parade. However at this price point I rather dough it.

Maybe, if your printer doesn't need a sine wave inverter. I'd find out before you try it. Search back issues/ask the folks at "Home Power" magazine if you don't find an answer. Their editors are very helpful with questions like this.

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.

Mitch: It's not an inverter-quality "clean." Plug all your sensitive electronics into anAPC/UPC battery-backup-surge-protector and you'll be good to go. Or go througha transfer switch to your building's main circuit panel.H--da has "clean" ones... ahem.... half-the-power and THREE-TIMESthe price... Your choice, but these are good units. Good Luck!

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.

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

I'm sorry. Being quite familiar with inverters in general and this one in particular, I don't know what that could possibly mean nor does my manual on it reveal what it means.

I have not noticed a problem with the charge controller. Inverters WILL generate hash, but only in a few places. I have noticed it in the 40-meter ham band.

I just installed one recently. You are correct, this doesn't plug into an inverter. Instead, the meter display connects only to the solar charge controller for which it is built. Some inverters also have separate remote monitors that you can buy. I chose not to purchase a separate monitor/meter for my inverter since I can clearly see the inverter display where mine is mounted.

You should definitely look in the product manual for your inverter (probably available online). The manufacturer of my 300-watt pure sine wave inverter specifies a 40 amp fuse.

No, actually there is not. What you have is in effect a local source of 120VAC, isolated from the power grid and from ground. I'm not sure what would happen if you grounded the output outlet. It might short the inverter circuitry to ground and cause a failure.

Hi Edward,This is the right way to use the inverter>>> http://www.amazon.com/review/R3RTW2NTIXFOON/Hope this helpsRegards,Angela CS Email Representative

Ed, do not purchase this inverter, it is not properly designed. The inverter only has a 50 cycle output and can not run any type of motor.

No its a modified sine wave. Do not purchase this inverter it has a 50 cycle 120v output. It will not work for many North American rated devices. The stated specifications are incorrect.

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).

This is a modified sine wave inverter. I have used it with tv, laptops and for charging phones and camera batteries, and using a nutri-bullet blender without a problem.

NO it is not! We ordered this and when got here was not what we thought. Then company wanted us to spend $100 to ship it back. So we sold it here locally to someone off of craigslist. If you want an invertor...this is not one.
