what's the advantage of Off-grid pure sine wave inverter?


Pure sine wave inverter can better load high-power electrical products, such as motors, compressors, relays, etc.. Because inductive load  products need the current startup about 5-7 times than a normal operation .

For example, a refrigerator need normal operation about 150 watts,But the starting power up to 1000 watts or more. Further, since the inductive load in an instant power or disconnect the power, it will produce a counter electromotive force voltage, peak voltage which is far greater than the inverter can withstand voltage, it can easily lead to the inverter instantaneous overload , affect the service life of the inverter. 
Therefore, such a high electrical power supply waveform requirements.

If you don't know whether modify or pure sine wave you choose. Hope it will help you.

6 tips on How to choose a car inverter?

Many  friends are very familiar with the car inverter, which is our driving equipment necessary. Of course, there are many novice friends do not understand the use of car inverter, in fact, car inverter is a direct current (DC) into AC (AC) device. There are many types of inverters on the market, how to choose? We share my experience today and hope to help you. You have to know how many of your  car battery voltage, the general use of 12-volt battery in car, the use of diesel engines (including trucks) such as buses, trucks and most use 24-volt battery, a few still use 12-volt battery. Each inverter has access to the DC voltage value, requiring the choice of battery voltage must be consistent with the inverter DC input voltage. 12V battery must choose 12V inverter. We have to understand the battery capacity, the general battery printed with a lot of letters and numbers, as long as the words to find XXAH can know that this is a large capacity of the battery. ...

whats the trend and significance of Digital Control System Based on SCM? What is its advantage?

With more and more applications of inverter power supplies, the demand for the development of inverter power supply technology is also increasing. At present, the design of inverter power supply adopts a structure composed of discrete components designed by pure hardware. As the number and type of appliances used by people increase, the higher the waveform and capacity requirements of the inverter power supply, the higher the complexity of the inverter power supply design and the more components used. However, due to the excessive number of components and the poor stability of the power supply, the entire system is often damaged due to poor quality of a component. In addition, the traditional inverter power supply is based on the design of analog components and has no programmability, which makes the reversible power supply less scalable and has no display function. Therefore, the microcontroller is very important as the master chip of the inverter power supply. With the deve...
