How does a photovoltaic inverter work?
Usually, when no abnormal fluctuation occurs at the voltage of a PV grid-connected system, the photovoltaic inverter generally controls both the output voltage and current under sine wave and the same phase, so the output PF becomes 1.0.
What happens when a photovoltaic smart inverter starts voltage-power control?
When the photovoltaic smart inverter starts voltage-power control, should the mains voltage and frequency still fail in steady parallel operation and exceed the normal range, it must automatically trip to avoid damage. Figure 9 displays the reactive power control architecture for the smart inverter .
