6 FAQs about [The life and death chess game of photovoltaic inverters]

How long do PV inverters last?

For reliability, the statistical failure rate and designed life expectancy of PV inverters are 0.9/year and 15 years, respectively . The inverters is generally considered one of the weakest points in a PV generation system. The output power of a PV module fluctuates and is random.

How intelligent is a PV inverter system?

Although various intelligent technologies have been used in a PV inverter system, the intelligence of the whole system is still at a rather low level. The intelligent methods are mainly utilized together with the traditional controllers to improve the system control speed and reliability.

How does a PV system affect power quality?

However, the control performance and stability of the PV system is seriously affected by the interaction between PV internal control loops and the external power grid. The impact of the PV system on the reliability, stability, and power quality of power systems has restricted them to further participate in power supplies with a large capacity.

What is the control performance of PV inverters?

The control performance of PV inverters determines the system’s stability and reliability. Conventional control is the foundation for intelligent optimization of grid-connected PV systems. Therefore, a brief overview of these typical controls should be given to lay the theoretical foundation of further contents.

What is a photovoltaic system?

A photovoltaic system is an assembly of components that produce and supply electricity based on photovoltaic conversion of solar energy. It comprises the following sub-systems: module array, switches, controls, meters, power conversion equipment, PV array support structure, and electricity storage components.

What are the challenges of SiC-based PV inverter?

However, the SiC-based PV inverter is challenged by many issues, as shown in Fig. 12. Due to the very fast switching speed, high dv / dt, and di / dt, the employed SiC devices cause serious ringing, cross-talk, etc. These issues are discussed in detail as follows. Fig. 12. Configuration of SiC-based PV inverter with challenges. 4.1.
