Alternating current is a type of electric current whose voltage is varying at constant intervals in a cyclical manner, half the time it will be positive (the energy circulates in one direction) and the other half negative (it circulates in the opposite direction) forming, normally, a sine wave.
What are the characteristics of a modified wave inverter?
The main characteristic of a modified wave inverter is the shape of the waveform of the alternating current it generates, which is not a sine function (like that of the current of the conventional electrical system). During the DC to AC transformation process, a square wave is obtained, which is then electronically smoothed, with the intention of making it more similar to a sine wave, until the final modified wave is obtained. In the following image you can see the difference of each one of them:

When is it worth buying a modified wave inverter?
Modified wave inverters can present you with some benefits over pure wave inverters, for example, their price, which is significantly lower. But, on the other hand, the fact that the current wave is not a pure sine wave can also cause you some problems when using it. So, is it a good idea to buy a modified sine wave inverter for a camper van?
Devices that may not work well with a modified wave inverter
Modified wave inverters present more problems when using devices with the following characteristics:
- Appliances with AC motors:
- Appliances: some blenders, fans, hair dryers, etc.
- Tools: Drills, electric saws, radials, etc.
- Water pumps.
- Complex appliances or appliances with electronics that work with AC (those without a transformer):
- Refrigerators.
- Microwaves.
- Air conditioners.
Appliances that should work perfectly with a modified wave inverter
Instead, they work perfectly, without any kind of problem or difference with respect to a pure wave inverter with these others:
- Devices that use a current transformer, either externally or internally. Devices such as the following may have a transformer:
- Household appliances and electronic devices: televisions, desktop computers, smart assistants, sound equipment, etc.
- Battery-powered appliances in general: Laptops, cell phones, tablets, battery chargers, battery-powered tools, etc.
- Appliances with DC motors (DC in English):
- Household appliances: Some small blenders, hair dryers, etc.
- Lighting.
To know if your appliances and household appliances would work properly you should carefully read their characteristics, to know if they use a transformer or the type of motor they have.
Benefits and disadvantages of modified wave inverters
Advantages of modified wave inverters
- Modified wave inverter technology is simpler and more reliable, so it will generally have fewer failures.
- As simpler devices, they are lighter in weight.
- They are considerably less expensive.
Disadvantages of modified wave inverters
- Modified wave inverters can tend to overload since their maximum voltages vary according to the voltage present in the battery.
- They are not suitable for inductive loads (transformerless and/or AC motorized electronic devices).
Final conclusions on modified waveform inverters and their price
We, personally, have not used a modified wave inverter, our inverter is a Phoenix Victron 12V 800W pure wave (see on Amazon). But, making this post, we have gathered a lot of information from real users who have shown their opinions and helped us to draw our own conclusions:
While it is true that it is always usually said: pure wave inverter yes or yes and that at the time of buying it we had no doubt in choosing it, now, after researching I do not think it should be so resounding that decision. Each case is very particular, so you will have to analyze your situation very well. If your budget is somewhat tight and you think that the devices you will use fit well in the group of devices that do not have problems with modified waves (devices with current transformer, DC motors and lighting) these inverters may be a good option for you.
A modified wave inverter is cheaper, simpler and more robust than a pure wave inverter and may work perfectly for many users, while for many others it will be a piece of junk without any utility.
Many times we sin of always wanting to buy the best we can afford and there are many times when it is not necessary. My advice, if you allow me, is to value your situation and your needs and decide what suits you best.
