FAQs 6

What is the European standard for photovoltaic inverters?

This European Standard describes datasheet and nameplate information for photovoltaic inverters in grid parallel operation. The intent of this document is to provide the minimum information required to configure a safe and optimal system with photovoltaic inverters.

What standards are available for the energy rating of PV modules?

Standards available for the energy rating of PV modules in different climatic conditions, but degradation rate and operational lifetime need additional scientific and standardisation work (no specific standard at present). Standard available to define an overall efficiency according to a weighted combination of efficiencies.

Why are PV inverters becoming more efficient?

The new generation of PV inverters are becoming more efficient, with efficiencies greater than 97% The efficiency is brought about by changing the topology of the power converter or control scheme or by better circuit board layout techniques.

What is the average model of a single-phase PV inverter?

Averaged model of a single-phase PV inverter The average model is implemented in PLECS. The model uses the same parameters as the homegrown inverter except for the input voltage source, which is replaced with the PV current source. The model is designed for the same switching frequency, DC-link voltage and AC grid voltage.

How is the lifetime of a PV inverter predicted?

Up to a certain point in time, the entire lifetime of a PV inverter was predicted based on the failure rates of individual components and handbooks provided by the manufacturers. In recent years, the prediction of the reliability and lifetime of power converters has been done through physics-of-failure assessments.

What certifications apply to solar inverters?

There are several certifications that apply to solar inverters, including EN 50524, EN 50530, UL 1741, IEC 61683, IEC 62109-1, and IEC 62109-2. Before going into more detail, let’s briefly discuss the main certification bodies that design and safeguard these certification standards for solar inverters.
