The inverter is more important safety certification

The present era, the inverter is essential to life power products, while consumers tend to pay more attention to the 5000w pure sine wave inverter on the most important thing is what?
Is the voltage it? Electric power? Performance? Current? Quality? Prices? These are not the point! The most important is the safety certification is more important.
May I ask why? -
Because the current power products are transported to rely on the current work carried out, the current instability and the voltage is need to compare the product use caution use yes. And these are minor. Most importantly, the inverter safety certification more important and critical.
Because if the product does not pass safety certification, then it belongs to the unqualified power products, will buy these products in general consumers are some of the more price conscious people.
Because the failure of the power supply price is relatively cheap, of course, provided that the consumer does not know who bought the product is not no safety-certified. Just based on the price and purchase of distinction.
The inverter is the safety and quality assurance, the price is secondary. If you choose to use unqualified power products that will be some problems, may cause a short circuit, it can lead to more serious leakage or loss of power may cause the safety circuit, etc. These problems lead to failure!
So I chose the most important power products is more important to pay attention to safety certification, of course, quality and performance, voltage, current, and so these are very important to choose a more reliable power supply choice of profession safer and more at ease!
