Our pure sine wave inverter outputs sine wave alternating current in the same form as our daily power grid and is in some ways better because of the lack of electromagnetic pollution in the power grid. Pure sine wave inverters can drive any device that can be connected to the city grid. In addition, the output waveform of pure sine wave inverter is basically consistent with the alternating current waveform of city power grid.
There are two main types of waveform of inverter. One is a sine wave inverter (pure sine wave inverter). Another one is square wave inverter. A square wave inverter outputs relatively low-quality square wave alternating current, whose positive maximum and negative maximum occur at the same time, causing a drastic effect on the load and the inverter.
The power of the inverter must be above the rated power of the operating appliances: Considering the high start-up current of some appliances, inverters with high output power should be chosen.
Protection for overload: After powering the inverter, turn on the switch and connect the inverter to the load indicated above the overload protection power. The inverter will then prepare for overload, indicating protection for overload.
One of the most important parameters related to your choice is its power. Appliances with different powers require different specifications of inverters to match. Thus you should be aware of the power of appliances you prepare to operate when you choose the inverter. Once the required power source of a automotive electrical appliances is 500W yet you choose an inverter with power of 300W, the inverter will be of no use.
With the popularity of electronic products, inverters are more and more widely applied in various occasions and use. Different uses correspond with different usage conditions yet not all conditions require inverter because operation of inverter requires specific conditions.
