Test & Certification of Inverters
Solar & Wind Energy
In the global energy production the role of RE is continuously increasing. From the smallest to the largest investors everyone is looking for opportunities in this fast growing government supported sector.
By utilizing the inexhaustible energy generated by solar panels and wind turbines the consumption of the fossil energy resources can significantly be decreased.
Challenges for the inverters
At solar panels (and at some wind turbines) the generated current has continuously changing parameters, which is converted by inverters to 50/60Hz alternating current. The inverters must always have appropriate characteristic like safety and high efficiency. In addition to that, their electrical and mechanical components must have long service life. These and the other high requirements are real challenges for the manufacturers and are particularly important for the investors and users.
Grid compatibility, quality requirements
The inverters of the renewable energy systems connected to the grid must fulfill several requirements. These are the life and property safety, as well as reliability. Also important parameters are the quality of the generated current (THD, cosΦ, protective functions), ability to avoid the island operation, operational reliability, electromagnetic compatibility, construction quality and the quality of the documentation. There are challenging task for the manufacturer and important characteristics for the buyers.
Requirements – standard compliance – intrinsic value
The international and European standards ensure stable support in the large diversity of requirements. By the proven compliance with the relevant standards is ensured for the manufacturers, that they can safely sell their products on the global market and for the investor that his investment is safely protected.
