The cost of modified wave inverter and square wave inverter is usually low, but the efficiency is far lower than that of pure sine wave inverter. In addition, some electrical appliances can not work normally in these inverters. Pure sine wave inverter has stronger load effect and load capacity, which can provide stable and efficient pure sine wave output for electrical equipment, but the technical requirements and cost are relatively high.


Let's take a look at the differences among pure sine wave inverter, modified wave inverter and square wave inverter


1. The output waveform is different


The difference between pure sine wave inverter, modified wave inverter and square wave inverter is that the output waveform is different. Pure sine wave inverter generally adopts PWM mode, and some even add multi-step inverter. The structure is complex, but the output waveform is good, which is suitable for inductive load and capacitive load. The modified wave inverter generally adopts square wave mode, and a few add step inverter. The structure is simple, but the output waveform is poor, so it is not suitable for inductive load and capacitive load.


2. There is a gap in efficiency


Compared with the modified wave inverter and square wave inverter, the pure sine wave inverter has higher efficiency, stable sine wave output and high frequency technology, which is suitable for all kinds of loads.


3. Noise and loss


Pure sine wave inverter is suitable for inductive load, capacitive load and resistive load. Modified wave inverter and square wave inverter are only suitable for resistive load. If modified wave inverter and square wave inverter are used in inductive devices, they will make a lot of noise, and the loss of electrical devices is also very large.


The output waveform of pure sine wave inverter is good, the distortion is very low, and its output waveform is basically consistent with the AC waveform of the municipal power grid. In fact, the quality of AC provided by excellent pure sine wave inverter is higher than that of the power grid. The pure sine wave inverter has the advantages of small interference to radio, communication equipment and precision equipment, low noise and strong load adaptability. It can meet the application of all AC loads and has high efficiency.


The output of pure sine wave inverter is the same or even better sine wave AC as our daily power grid. There is no electromagnetic pollution in the power grid. In short, it has a wide range of application, strong load capacity and excellent stability. It can provide the same AC as ordinary household, and can drive almost any kind of electrical appliances under the condition of meeting the power.


From the comparison of all aspects, we can see that the pure sine wave inverter is better than the modified wave inverter and the square wave inverter in all aspects. The pure sine wave inverter manufactured by SanRui adopts full digital intelligent control technology, which has the characteristics of fast dynamic response, strong load resistance, small input surge current, safe and stable operation, etc. The product is simple in appearance, light in volume, simple in operation, and easy to install.
