6 FAQs about [Photovoltaic power generation directly connected to the inverter]

What is photovoltaic grid-connected inverter?

Photovoltaic grid-connected inverter is an essential key component in photovoltaic power generation system. It is mainly used in the special inverter power supply in the field of solar photovoltaic power generation.

What does a PV inverter do?

PV inverters serve three basic functions: they convert DC power from the PV panels to AC power, they ensure that the AC frequency produced remains at 60 cycles per second, and they minimize voltage fluctuations. The most common PV inverters are micro-inverters, string inverters, and power optimizers (See Figure 5). Figure 5.

What is solar photovoltaic (PV) power generation?

Solar photovoltaic (PV) power generation is the process of converting energy from the sun into electricity using solar panels. Solar panels, also called PV panels, are combined into arrays in a PV system. PV systems can also be installed in grid-connected or off-grid (stand-alone) configurations.

How a photovoltaic system is integrated with a utility grid?

A basic photovoltaic system integrated with utility grid is shown in Fig. 2. The PV array converts the solar energy to dc power, which is directly dependent on insolation. Blocking diode facilitates the array generated power to flow only towards the power conditioner.

How does a grid-connected inverter work?

Before grid-connected power generation, the grid-connected inverter needs to take power from the power grid, detect the parameters such as voltage, frequency, phase sequence, and so on, and then adjust the parameters of its own power generation, synchronize with the grid’s electrical parameters.

How does a photovoltaic grid-connected power generation system work?

During normal power generation, the photovoltaic grid-connected power generation system is connected to the large power grid to transmit active power to the power grid. However, when the power grid loses power, the photovoltaic grid-connected power generation system may still work continuously and operate independently of the local load.
