The main function of the photovoltaic grid connection cabinet.

During operation, the photovoltaic grid-connected cabinet may experience fluctuations in grid-side voltage, frequency, and other aspects, which can impact the station, leading to phenomena such as excessive load. This not only poses a risk of damage to grid equipment but also threatens the safety of maintenance personnel. The issue of harmonics is a major problem in photovoltaic power generation. Photovoltaic power generation uses AC and DC inverters, and since inverters operate through the switching on and off of semiconductor power switches.
