How to choose the inverter you need

The inverter is a machine that occupies an important position. It has a wide range of applications, from homes to power stations. In the field of new energy, it is even more dominant in the field of solar energy and wind energy.

The so-called inverter is to convert direct current into alternating current so that the output current meets our requirements. Inverters can be divided into square wave inverters, modified wave inverters, and sine wave inverters according to the waveform; according to whether they are connected to the power grid, they can be divided into grid-connected inverters and off-grid inverters.

How to choose the inverter you need? Mr. Wang from Yufan Electric suggests that you can choose according to the following methods. First, whether the inverter you need is connected to the national grid. If not, it is an off-grid inverter. Second, what is your load? If it is an inductive load, you should choose an inverter with a power 2-3 times that of the load power. Third, whether there are strict requirements for the inverter waveform. If there are strict requirements for current, you must use a sine wave inverter. The harmonics generated by the square wave inverter are relatively serious and the power loss is large.

The price of sine wave inverter is generally more expensive, but it is more cost-effective than square wave. At present, solar inverter and photovoltaic inverter are very popular. With the economic recovery this year and the rapid development of new energy industry, the market demand has increased.
