Inverter transfers DC to AC current, makes the output current meet our requirements. According to the waveform points can divide the inverter into square-wave inverters, modified sine wave inverter, sine wave inverter, in accordance with the grid connection points can be divided into a grid-connected inverter and off-grid inverter.
How to choose the inverter? omnik recommendations that you can select the following manner. First, if the inverter you need is electricity grid access, if not just choose the off-grid inverter. Second, what is your load, if that is inductive load, you should choose power is 2-3 times of the load power inverter. Third, whether you have the strict requirements of the inverter waveform? strict requirements on current is necessary to use sine wave inverter current, harmonics generated by the square wave inverter is serious and a large power loss.
Sine wave inverter prices are generally more expensive, relatively square wave in terms of cost is quite high. Now solar inverters, photovoltaic inverter is very hot, this year's economic recovery, the rapid development of new energy industry will increase the market demand.
