Pure Sine Wave Inverter vs Modified Sine Inverter - Which one is right for YOU?

Check out our line of inverters here:
Pure Sine Inverters: wagan.com/coll...
Modified Sine Inverters: wagan.com/coll...
Pure Sine or “Normal Sine, Sine, Pure Sine, PSW, True Sine“ is the smooth sine wave as seen in the picture above. In the simplest of explanations, it is the cleanest and best type of sine wave due to its smooth oscillation waveform. Pure sine is the type of sine wave that comes from your AC (wall) outlets in your house and allows all electronic devices to operate smooth, clean, and efficiently.
Modified Sine or “Square, Modified, Simulated, MSW” is a manufactured type of sine wave that is less expensive to produce. Able to operate with most electronic devices, it is an affordable and adaptable alternative to the Pure Sine Wave Inverter.
Getting Technical
Pure Sine Wave (PSW) is the best because the voltage rises and falls smoothly and changes polarity instantly when the voltage crosses 0V (zero volts). This does not cause excessive heat build-up or add stress to electronic devices as it is a smooth and consistent change.
On the other hand, Modified Sine Wave (MSW) is more like a light switch with abrupt voltage rise and falls (as seen in the waveform) with long periods of rest at 0V. This abrupt change causes some devices to simply not work, create electrical noise, over-heat, and can cause failure in sensitive electronic devices.
So what does that mean for me?
Ideally, the Pure sine Wave (PSW) is the best solution to your power needs; it allows all electronic devices to operate as intended. The downside of a PSW inverter is the cost to manufacture it; the price can be 2-4 times the amount of a Modified Sine Wave Inverter.
Modified Sine Wave Inverters (MSW) are inexpensive to produce and provide the same amount of power (in watts) as the PSW Inverters do. Unfortunately, the square sine wave produced is not compatible with some sensitive electronic devices such as rheostats (dimmer switches, variable speed devices), built-in clocks, heaters, CFL & HID lights, some power tool battery chargers, sewing machines with variable speed controls, copy machines, and laser printers.
Which is my best choice?
If you are in need of an inverter that is going to power sensitive electronics such as: medical devices, computers, anything with a dimmer/variable speed, heater/heating coil, or just needs clean power; buy the pure sine inverter… you can’t go wrong with that choice.
On the other hand, if you need temporary power while tail-gating, camping, road-trips or to charge your laptop/two-way radios, power fans, run a blender, power a microwave, etc., the modified sine wave inverter is smart and affordable choice.
The Take-a-way
Modified Sine Wave inverters sound scary, right? In reality, MSW inverters are not scary, dangerous, etc., they just need to be used appropriately. I have used a MSW inverter for most of my life during camping, road-trips, RVing and the like…and have never experienced any problems with them.
MSW Inverters are perfect for 90% of applications for the average user; you must realize their limitations and use them accordingly. Want to err on the side of caution(?)... buy a Pure Sine Wave Inverter and you cannot go wrong!

I have had an older Vector 3000w 12v MSW inverter since 2007. (Vector was bought out by Coleman) It was the first one I ever got. I paid $70 at a pawn shop. I did use it for a year or so. Mainly at night to power my tv and a couple of lights. As I had 4 12v 100ah marine flooded batteries in parallel. I charged them with solar. I had a meager existence back than. Still do. Lol. I still have it though I have a Xantrex 2000w PSW inverter/charger for day- to-day use. It works beautifully. I have a 1000ah 12v lithium battery bank now. I keep the old vector forca hyst in case scenario. And I'm glad I did because my Xantrex recently had an issue for which it had to go out of service. Good to have a plan B.

Brings back memories of using these oscillators at high school. I asked my physics teacher why the peak and low were fuzzy in my lab experiment and he said it was due to poor wire connection, air/oxygen acting as capacitor and sure he was thrilled someone asked that question. Thanks for the great explanation. For my RV, PSW it is going to be. Subscribed.

The fact that Justin replies to viewers inquiries made me subscribe without question. Anyway, I have a 1500W MSW inverter and currently learning what can I use it for. I bought it mainly to lessen my electric consumption from the grid and aid my electric needs when there are power outages. Learned it the hard way that a 7Ah battery would only last you a couple of minutes and the other two 40Ah lead acid batteries I have needs to be overhauled. The other one won't take charge and the other just discharge by itself really quick. I am thinking on investing on a 150Ah solar battery but it would cost me couple hundred dollars. It would be nice to be able to run at least one room on pure solar.

[@WaganTech]

Aliah, thanks for the love, I truly appreciate it and I love engaging with the people who took the time to watch the video! If you need help determining what size battery bank would fit your needs, add up the wattage that your room uses in a day and shoot that number over; I can give you an estimate of what Ah battery bank you'll need. Additionally, look into getting multiple batteries or even wiring 6V batteries in series to get the battery bank you desire (you don't necessarily have to use only 1 battery in your set-up)! -Justin

[@Barkley1835]

@@WaganTech Thank you so much, man! That's actually smart! Maybe I'll buy batteries(20-40Ah) one at a time so I don't have to spend one time on a single battery. Will it be fine to connect five 40Ah batteries in parallel? That way, I would have a 200Ah battery set instead of a single 150Ah or 200Ah battery. Total wattage for my room is 633W. Mainly lights, chargers and two inductive loads, a fan and a 3D printer with peak power at 270W. I tried to open the printer power supply connected to the inverter but it doesn't turn on. What more is instead of low voltage beep the inverter doesn't beep at all but gives off a small tricking sound. I immediately disconnected it since it doesn't sound good if it last any longer.

[@WaganTech]

​@@Barkley1835 You can connect 5 of the 40Ah batteries in parallel and it will work fine for powering your inverter, but you'll have trouble charging them. If you connect a battery charger to the first battery, it will fully charge, but each sequential battery will receive less of a charge and won't ever fully charge; I would only recommend charging a max of 2 connected batteries in this battery bank set-up. As for the inverter, is it one of ours? If so, which model? The 3D printer uses a heated assembly (hot end) and can be problematic with MSW inverters. If possible (and can be done by a trained professional), I would check the inverter's fuse(s).

Propably to late but make sure you will use proper batteries. Typical lead-acid batteries used in cars cant be fully discharged and their life span will decrease drasticly every time you do that.

I've definitely have had issues with modified sine wave inverters for my laptops, I've had it cause the mouse to jump around and some weird stuff like that. More electrical noise, I definitely think it can cause problems for a laptop

[@WaganTech]

In general, I wouldn't recommend MSW inverters for use with sensitive electronics like computers. However, laptops are usually ok since they have a transformer built in that "smooths" out the incoming current. Of course, this isn't always true for all inverters/laptops as you may have found. If the inverter was one of ours, it most likely would have worked just fine with your laptop.

[@lauramerrill4783]

My house has run off a modified sine inverter for all of its 25 years, with only a couple of hiccups. First, I can't install a regular commercial washing machine, because it gets to a certain stage of its (computer-run) cycle, and shuts off. So I go to the laundromat, or I could buy a very expensive Stabler washing machine, which I know works. The latest issue has been the Ninja Creami. Just won't run. I have to use a generator to make it work. Would a small, plug-into-my-main-system pure sine wave inverter solve the problem?

Short term, MSW is fine, but if you use it regularly, definitely consider using pure sine inverters instead.

[@alexandercrash2191]

I have a msi gaming laptop. Any truckers out there looking to game out on the road like myself, a modified sine wave will not charge this laptop.

[@WaganTech]

Great reasons. Even all pure sine inverters are not built the same. Wagan Tech pure sine inverters have a less than 3% THD, so they're even cleaner energy. Our inverters are used in military, first responder, and government applications.

[@rollinronin8125]

It would be good to solidly know the best. I repeat BEST case scenarios and devices and appliances that would do well with a MSW inverter.

[@WaganTech]

For most people with occasional use and limited budget, MSW is just fine. If the inverter is being used as the workhorse for sensitive electronics, motor driven devices, or similar, we recommend PSW. Look for ones that are UL/ETL certified for safety and reliability.

[@MaxxSteele]

Most modern electronic equipment actually operates on DC. They either have a wall wart that converts the AC to DC or they have an internal AC to DC circuit with full wave bridge rectifier. Does a power supply really need a pure sine wave to preform as needed.

[@WaganTech]

You are correct that most electronic equipment runs on DC. The answer to whether it needs a pure sine wave or not is not as simple as it seems. We've tested a bunch of transformer power supplies with a multitude of inverters and have found that some transformers do not work well with modified sine wave.

[@curtchase3730]

A MSW "will" operate nearly any device rated for standard line voltage, BUT not as good as a PSW inverter. Everything, but maybe a heater or old fashioned light bulb will take a performance hit from a MSW inverter, as much as 20% loss compared to a real sine wave AC source. If you try to measure the output voltage from a typical modified sine wave inverter with a standard cheap multimeter, it will read around 108-112 volts. It is showing an average voltage level. To prove a point, take 2 inverters, one MSW, one pure sine wave both rated at least 1000 watts. Plug a vacuum cleaner into one of them, listen to the noise. Then plug vac into the other one and listen again. When plugged into the PSW inverter, vac will run faster than when plugged into the MSW unit! Like the video says, a pure sine wave inverter will cost more than a MSW, but nowadays it's not 2 or 3x the price. Another downside of a pure sine inverter, is that it draws more idle current than a mod sine unit. Those low frequency (iron transformer) heavy jobbers are really pigs. Always tradeoffs.

[@WaganTech]

Very well said, Curt! Another good test is with a fan. A fan plugged into an MSW inverter will have a "humming" sound. When plugging the same fan into a PSW inverter, the humming sound won't be present.

I drive an 18 wheeler. I have 2 truck stop inverters running my electronics and appliances. My appliances are running fine as far as I know but my 43' tv and my ps5 hum while I'm using them. I'm thinking I need a pure sine wave inverter. Thoughts?

[@WaganTech]

Jeremy, Let's talk about that PS5 and 43" TV in an 18 wheeler?! That is AWESOME!!! As you suspect, that electrical noise is likely made by the sine wave produced from your inverters. But, before you go and drop all that cash on a new inverter, there are some options to consider. You can try using ferrite rings on the power supply line, they're inexpensive and can reduce line noise. You may want to look into devices called "noise/line/supply/EMI" filters (usually $10-20). Although these are more intended for alternator/ignition signal filtering, they can often have beneficial effects on inverter/appliance noise filtering. It is possible that the inverter is emitting an electrical noise (EMI), shielding the electronics may help. Additionally, make sure that you are using large enough gauge cables to the inverter and that you are using the inverter's grounding terminal correctly (to a chassis ground). Alternately, you may opt for a quality PSW inverter and be done with the interference completely.

[@jamesmancine8350]

Considering the majority of inverters are manufactured overseas, what really is it that costs so much more to produce a psw over a msw, besides a few extra computer control boards manufactured by a robotic device with minimal hands on assembly? I've seen plenty of inverter components and video breakdowns including the Wagon brand and they all seem to have more in common than different.

[@WaganTech]

James, you bring up a really good point. For the most part, you are right; an inverter is an inverter with no discernable differences between models/brands/etc. to the untrained eye. When you really get into the inverter, you'll see major differences in components: quality/lifespan/ and most importantly lifecycle. The first thing you'll notice with our inverters is the conformal coating. This is not something that every manufacturer does as it adds costs, but it adds weather-resistance, protects the circuit board (from stuff like dusts), and increases the overall life and reliability of the unit. Component quality is another benchmark. Cheap components breakdown quickly and tend to fail early. We commonly see this with less expensive brands; the components will work for a few months, and then cease operation altogether rendering the inverter useless. Our inverters source reliable quality components that are tested and duty-cycle rated to perform at or above our standards. They are run at thousands of cycles and for weeks upon end to ensure that they can handle the loads applied to them. Another important factor is over-rating components to handle the use/misuse often applied by the human hand. Another critical aspect of inverter manufacturing is ensuring that the components are correctly sized to handle the task. We've seen lesser inverters running barely capable capacitors/transformers that will only handle the correctly sized load - if overloaded, they become damaged and no longer work. They'll use a 17V component because its cheaper, while we'll use a 24V unit to handle the occasional overload because it's better. Another performance factor is the actual output of the inverter. This is a HUGE one! Many (if not most) inverters will claim a wattage on the unit, but is unable to sustain that wattage for any useable length of time. This is the reason that we coined the term "TrueRated Power" - TrueRated Power is Wagan Tech’s coined term for truth in advertising and performance. While actual output wattage of competitor’s inverters varies greatly, Wagan Tech inverters help consumers to understand and trust that the number printed on the inverter is the actual output of the device (and will sustain that output load for at least 24 continuous hours). Lastly, we have "boots on the ground" in the factory who are constantly testing the units to ensure that each one can handle the use it was intended for. Quality Control is ultra important to us; we live by the "buy once, cry once" motto - we want you to have an inverter that is only installed once and never has to be messed with again.

[@WaganTech]

Mr. Shark, An electrical "hum" is normal when using an MSW inverter. This is due to the harmonics/frequency and the sine wave itself. Are you plugging your projector/laptop into a GFI outlet or directly to the inverter? The GFI can create a humming noise. Is there a box on the laptop/projector's power cord (switching power supply)? If so, these will usually filter the incoming power and create a buzzing noise while doing so; which is safe to use.

However, an ebay listing for a 1000w inverter threw me in a loop talking about how you have to buy one that is rated several times higher than what you want to use. I want to know if this is true? is it a pro tip for modified sine to offset any potential issues? Or is this simply a marketing tactic to get me buying more than what I need to part with extra cash? It didn't seems right to me so thought I would ask. Thanks.

[@WaganTech]

This is a great question and is semi-easily answered! Most inverters on the market will claim to output a specific wattage (like 1000W), but are only able to output that amount for a short amount of time (like 20 mins) before they have to start dropping - sometimes the drop is as much as 25%! We coined the term "TrueRated Power" to let our customers know that the power output printed on the inverter is the actual output that it will supply for at least 24 hours straight... in other words, our inverter says "1000W" and it will output 1000W. To keep the inverter in the optimal performance range, I suggest buying an inverter that is about 15-20% higher wattage than what you need. If you have a 500W load (or 5x100W devices), then I would suggest an inverter that is about 600W (if it's one of ours). Another issue that other manufacturers use is printing the "peak" or "surge" wattage as the inverter's name. This is misleading because you go out to buy a 1000W inverter and then find out that it is "1000W Peak" which won't power your required load. This is why we try to be transparent and helpful so our customers know exactly what they're buying.

Hi, Can I use one of this 2 inverters for a 1000watt commercial cheese machine and use for about 10h a day. If yes which one do you recommend? Thank you.

[@WaganTech]

You'd want a 1200W Inverter or "grater" (cheese pun!). The PureLine 2000 would be a great choice, but the issue you'd have would be having a battery/battery bank large enough to power the cheese machine for that long. A less expensive option would be our SlimLine 1500W Inverter, though you'd have the same issue with powering the inverter for that long.

[@elguapo7722]

My inverter gave off a burning smell. Now it turns on but anything plugged into it has no power. What could this be? Maybe internal fuses? Do you just open up the unit and change the fuses?

[@WaganTech]

Was it overloaded, over-heated, or got damaged? My guess would be the internal fuses. I would take it to a certified electrician and have them open the unit up to see what the issue is. If it is one of our inverters, then locating the fuses will be easy - easy to inspect and replace too.

I need an inverter to power my sump pump during power outages. My sump pump works fine but i have noticed it sounds different. I read that pure sine wave is more efficient. Is it the inverter that is more efficient or does my sump pump motor use more power on a modified sine wave ??

[@WaganTech]

If you're using a MSW inverter on the sump pump, the different sounds it is making is likely due to the inverter switching from the modified sine wave. This is normal operation, but would go away if you used a PSW inverter.

Are you sure it is not the TV that is having the problem? I've never heard of this happening even with really junky inverters. Usually if the inverter is the problem, I would see the TV turning off on it's own, not fluctuation of sound. Maybe the inverter is surging where it is giving lower power to the TV causing it to fluctuate? Try a different TV to eliminate that variable.

[@WaganTech]

I took a look at the specs on the @NorthernToolCo website and I see that it has an adjustable amperage range as you stated. 20-80A @120V would be 2400-9600 watts. If you're going to be staying at the lower end, I would recommend a 3000W inverter. Take note, the inverter will have to offer high output terminals as most inverters 120V AC outlets won't be able to handle 2400W+. If you're wanting a modified sine inverter, our ProLine series is made for you.

Hey There! You can charge a PPS from a modified sine wave inverter - most of them use a "brick" inline that help to smooth out power to the unit. As for the furnace, it is possible as long as you know the current draw it requires and what your vehicle's alternator is capable of outputting. A standard gas-fired forced air heaters draw about 600W which is acceptable for most vehicles.

[@shinobyninja1281]

What inverter you will need for a air tire compressor with AC cord

[@WaganTech]

Take a look at the air compressor and it should say what the wattage or amperage required to power it is (somewhere on it should say something like "110-120v" and "100w" or an amperage rating like "2.3a"). If the wattage is listed, then you'll know what size inverter you need... If it says "100w", then add the 20% as suggested in the video, and get an inverter that's 120 watts or greater. If it has an amperage listed, multiply that number to the voltage. Let's use the 2.3 amps example that I gave earlier, and it would be 2.3 x 120 (amps times voltage equals watts) to get 276 watts. Add the 20% to that and you would get around 331w.

What do you think can I get away with a mod sine of do I need to go with pure sine. Sorry so many questions thank you so much.

[@WaganTech]

Shaun, don't worry about the amount of questions, I am happy to help! AS for the battery, you may want to contact AC Delco. I suspect it is a Group 24 battery - but that won't tell us the Ah (amp-hour) rating of it. It looks like you're not powering more than 500W (unless you are running multiple items at once), so a 2000W Inverter would be too much for your needs. The coffee maker is one of those items that may or may not run of of a modified sine wave, everything else should run of of MSW. The heater and coffee maker would do better on a Pure Sine Wave inverter, I would recommend getting one of those. As for the inverter size needed, I would go for 1000W or less if you'll only be powering one item at a time. If you will be powering the coffee maker and heater at the same time, I would go 1500W. The fan, monitor, and mobile phone are pretty insignificant power loads.

What size inverter do I need to run a 1.5 hp well pump off grid?

[@StringerNews1]

1.5 mechanical HP equates to about 1119 electrical Watts. No motor is 100% efficient, so the actual power needed to run will be above that. What really matters is what it takes to start the motor. A 1500W inverter may be able to run the motor but not start it. Without measuring the peak current draw and inverter impedance, one can only guess about that part. If you can, buy from a place that takes returns, so if you find you need a bigger inverter, you can trade the other one in.

Question: Would a surge protector be helpful in keeping a proper current and voltage?

@@edwardroche2480 Most likely your wattmeter reading is incorrect as these instruments are often calibrated for sine wave currents

[@StringerNews1]

The short answer is that the pulse waveform of the MSW inverter contains energy at frequencies that the motor can't use. This unusable energy gets converted into heat. Because it makes more heat than normal, your refrigerator will be less efficient with a MSW. Not only does it draw more power (Watts), it will run more often. If you look at the percentage of time the compressor is running at a given outside temperature, you'll see that it runs more on MSW.

Kevin, it depends on the inverter settings. Our inverters usually (depending on the model) will emit an audible "low voltage" alarm at around 10.5V ± 0.5V and then completely shut-down at 9.5V ± 0.5V. We set the threshold at this level to protect the battery from over-discharging (which ultimately increases the battery lifespan).

Usually if it starts beeping, that means that the voltage is dropping from your battery that is powering the inverter and the inverter is letting you know that you are running out of power (usually alarm is at 10.5V).

Batteries provide a "stable" source of power to the AC units, a solar panels output varies depending on all conceivable factors, therefore the fluctuation in output would end up shortening the lifespan of the AC unit.

@@WaganTech That actually was going through my head yesterday when I was trying to figure some thing out. We just happened to have a kinda overcast day, rare for summer around here I’m thinking if I do a duel 6v system (12v) it should give it that ability to float its current between times of good sun and cloud. Thank you. It’s was a fleeting thought, but one that kinda dogged me last night. Another person had mentioned that without the batteries the whole system could just shut down and basically if I weren’t home it wouldn’t be able to reset.

Hello sir , I want to know what is the full list of devices that msw inverter cant operate them ( can’t let them work )

[@WaganTech]

For the most part, MSW Inverters can operate nearly any device. The only time that you may experience issues is with rheostat or dimmer switch controlled devices, some CFL bulbs, and some clocks. There is no comprehensive list as some devices may work with one unit but not another.

Wagan Corporation is there an simple equation for calculating the size of cables between panels and controller

@@user-yv9ui6co6r Are you referring to solar panels and the solar charge controller?
