Is this a square wave or sine wave inverter?

Square. It has pretty high voltage spikes on anything load less than 50W and I would not use it for anything that is sensitive to dirty power such as a laptop for very long.

First of all be carefull - this is a modified Sine Wave Inverter. Not all 110 volt equipment will run on Modified Sine wave especially certain medical equipment. To be safe you should purchase a Pure Sine wave Inverter to get same as House line voltage. The unit has a built in breaker that if it gets too hot it will shut down. Manufacturers Operation guide does not show a maximum operating time. Depends on heat and Battery longevity

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

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.

The solar charge controller is a Go Power GP-PWM-30 and the inverter is a GO Power GP-SW300-12 3000 watt pure sine 12 volt inverter.Joe

I severely doubt it, because the sine waves would NOT be in synch and that would play havoc with any electronic devices attached, changing the RMS voltage outputs. It would create very dirty power. If you want to do this, you should contact the manufacturer to see if there is some modification they can recommend. Otherwise, just split the outputs to different circuits, but be very careful to NOT share a common neutral, and provide a separate ground as well.

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

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

Hello, hhis pure sine wave inverter have input 12 VDC, output 110 VAC, the automatic switch we have con 110 vacío side

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.

Not this one, it has a 50 Hz output and may damage your TV. Consider something such as a Xantrex or other brand of pure sine wave inverter.

My husband does not remember, but it is probably a square wave - but we use it as a backup to a solar system and it would be corrected for that by the type of inverter we have on the system. The generator will power our whole 1200 sq ft house, including 3 split air conditioning units (trane brand). We have no problems with our electronics or ceiling fans when running the generator - but our inverter would take care of a problem.

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

I will have to get back to you on that question. I assume your inverter output is modified sine wave?Anyway i do belive you can charge the unit with dc power using a male male cord to go into your cigarette lighter. look up the manual online, it will say for sure.

I am a retired electrical engineer so I can tell you it is not necessary to scope the output of this inverter to tell you the output looks like crap as compared to a pure sign wave inverter. It is a modified square wave output that simulates a sign wave as close as possible. The only advantage of this inverter is it is cheap and has the ability to start inductive loads rather well because it can supply the necessary current needed to achieve motor starting. I use this inverter to run saws, drills, and a small air unit in my shop. I have to pure sign wave inverters that run my home because many electronic appliances require a pure sign wave. You can look up modified sign wave on the internet to see the difference in a modified sign wave and a pure sign wave. Hope this helps in your decision making.

It is not a pure sine wave inverter. That being said, it will operate 90% of anything you would want to run with no problems.
