The most important requirements for photovoltaic inverter PCB-深圳市海博精密电路有限公司

In photovoltaic systems, the electrical energy of solar cells is stored and converted into 220V or 380V AC power by inverters. The output voltage fluctuates greatly, so the requirements for inverters are high. The steady-state output voltage change rate fluctuates around 5%, and when the load suddenly changes, the output voltage change rate should fluctuate around 10%.

In general, the waveform distortion rate should not exceed 5%. If the waveform distortion rate is too high, it will cause serious heating of the load components, which is not conducive to the service life of the equipment and devices, and even affect the use of the entire system.

The optimal frequency operating point of the motor is 50Hz. If the frequency is too high or too low, it can easily cause equipment heating, reduce the operating efficiency and service life of the system.
