6 FAQs about [Photovoltaic grid-connected inverter hardware design]

What are grid-interactive solar PV inverters?

Grid-interactive solar PV inverters must satisfy the technical requirements of PV energy penetration posed by various country's rules and guidelines. Grid-connected PV systems enable consumers to contribute unused or excess electricity to the utility grid while using less power from the grid.

Do grid connected solar PV inverters increase penetration of solar power?

The different solar PV configurations, international/ national standards and grid codes for grid connected solar PV systems have been highlighted. The state-of-the-art features of multi-functional grid-connected solar PV inverters for increased penetration of solar PV power are examined.

How does a grid tied PV inverter work?

A typical PV grid tied inverter uses a boost stage to boost the voltage from the PV panel such that the inverter can feed current into the grid. The DC bus of the inverter needs to be higher than the maximum grid voltage. Figure 20 illustrates a typical grid tied PV inverter using the macros present on the solar explorer kit. Figure 20.

What is the control design of a grid connected inverter?

The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.

Can grid-connected PV inverters improve utility grid stability?

Grid-connected PV inverters have traditionally been thought as active power sources with an emphasis on maximizing power extraction from the PV modules. While maximizing power transfer remains a top priority, utility grid stability is now widely acknowledged to benefit from several auxiliary services that grid-connected PV inverters may offer.
