Bureau Veritas expands its laboratory for renewable energy in Germany

14/04/14

Türkheim, 14 April 2014 - Bureau Veritas is pleased to announce the expansion of its competence center for renewable energy in Türkheim, Germany, which is specialized in testing converter technologies, particularly solar inverters. The new testing system from Spitzenberger & Spies now allows testing and certification of solar inverters with powers up to 130 kW. This automatic test system has been acquired to cover the latest class of compact central inverters (0–130 kW) in Europe.

A wide variety of conversion technologies are used to transform primary energy from decentralized generation sites for distribution to the public grid, special grid systems or energy storage systems. Primary energy sources include solar power, wind energy, hydroelectric power and combustion engines. The enormous increase in smaller generators feeding renewable energy into the grid poses great challenges in terms of standardization and grid operation. Today, more than 60% of energy generated is derived from renewable sources on some days of the year. Consequently, private photovoltaic systems must also meet regulatory requirements to ensure the stability of the mains voltage.

The new Bureau Veritas testing system is able to simulate the global normative requirements for low-voltage ride-through (LVRT) and high-voltage ride-through (HVRT) under real-life conditions. The combination of high-precision power meters and PV simulators enables the efficiency measurement of inverters for all types of solar cells and plant configurations.

“With this laboratory expansion, Bureau Veritas is positioning itself as a one-stop shop for solar inverter certification. It is the only lab in Europe that can test and certify all types of devices up to 130 kW of PV power under one roof,” explains Michael Grytz, General Manager of Bureau Veritas Consumer Products Services in Germany.

“We can test inverters with powers up to 130 kW on site. This means that manufacturers are not burdened with additional costs for further external or internal testing. Using our brand new state-of-the-art laboratory equipment, which comprises the latest photovoltaic and grid simulators, our experts can verify compliance with the requirements for connecting to different grid voltage levels in numerous countries around the world. We also assist manufacturers with their CE declaration of conformity by quickly conducting all relevant tests. At our location in Türkheim, in addition to electrical safety tests, we also conduct environmental testing, electromagnetic compatibility (EMC) tests, efficiency measurements and IP testing as well as certifications, approvals and audits,” adds Mr. Grytz.

Bernd Kreitmeier, Laboratory Manager for Low Voltage Directive Energy Systems explains further: “We support manufacturers with a very fast and high-precision testing and certification process. This allows them to bring their products onto the market quickly. Thanks to our new, highly automated testing system and the technical expertise of the Türkheim staff, testing for a nominal power range of up to 130 kW can be done extremely quickly maintaining the same high quality standard.

The new testing system also gives manufacturers the ability to track the performance of their products by means of tests conducted during the development process and to make any necessary product improvements once the system is online,” says Kreitmeier.

Worldwide, more than 100 Bureau Veritas employees test and certify numerous renewable energy products and components. At the Türkheim location, the company employs 27 experts for Energy Systems.
