6 FAQs about [Photovoltaic grid-connected inverter certification standards]

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.

Are control strategies for photovoltaic (PV) Grid-Connected inverters accurate?

However, these methods may require accurate modelling and may have higher implementation complexity. Emerging and future trends in control strategies for photovoltaic (PV) grid-connected inverters are driven by the need for increased efficiency, grid integration, flexibility, and sustainability.

Are photovoltaic inverters able to meet der requirements?

Initial indications show that, in general, photovoltaic (PV) inverters are able to fulfil both the static and the dynamic requirements. Besides the new requirements of the guideline, an extensive certification process for DER units and plants has also been introduced.

What is an inverter certification test?

The inverter certification tests must also provide data to show maximum power tracking effectiveness, efficiency variations associated with power line voltage, environmental effects, and losses that occur at night and during protective shutdowns.

What percentage of PV systems are connected to high-voltage grids?

At the end of 2009, more than 23% of all PV systems with an installed capacity of 2279MW were connected to medium- and high-voltage grids . The share of ‘large’ PV systems above 100kW rated power is showing a strong increasing trend.

Why do you test & certify your inverters & converters?

We test and certify your inverters and converters with AC output, either grid connected or in stand-alone operations, according to local and international specifications and standards to ensure their safety, quality and compliance. Successful test results can lead to certification and the right to use our internationally recognized test mark.
