The on grid inverter are generally used in the system of large photovoltaic power stations. Many parallel photovoltaic strings which has been connected to the DC input of the same centralized inverter. That is to say, three-phase IGBT power modules will be used for higher power.

The on grid inverter should not only convert the DC output from the solar photovoltaic power generation system into AC, but also control the voltage, current waveform, frequency, phase, and synchronization of AC, but also solve the problem of the power grid.

The on grid inverter sends energy directly to the grid, so it needs to track the frequency and phase of the grid, which is equivalent to a current source. Of course, some inverters have low voltage ride-through capability and can be used for PQ adjustment.

The on grid inverters provide various power conversion and access solutions for various renewable energy power generation systems such as solar photovoltaic power generation, wind power generation, fuel cell power generation, and small hydropower generation.
