The output frequency of inverters has different requirements in different application scenarios. Here are several typical application scenarios:

1. Solar power generation: In solar power generation systems, inverters need to convert the direct current generated by solar panels into alternating current for household use or integration into the grid. In this case, the output frequency of the inverter needs to be consistent with the grid frequency to ensure smooth transmission of electrical energy.

2. Wind power generation: In wind power generation systems, inverters need to convert the direct current generated by wind turbines into alternating current. Due to the large speed fluctuations of wind turbines, inverters need to have strong adaptability to ensure the stability of output frequency.

3. Uninterruptible power supply: In an uninterruptible power supply system, the inverter needs to quickly switch to battery power supply when the mains power is cut off to ensure the continuous operation of the load. In this case, the output frequency of the inverter needs to be consistent with the mains frequency to ensure the normal operation of the load.
