Measuring campaign „Zukunftskraftwerk PV“ (PV Power Plant of the Future) in TestLab Power Electronics

The central activity of TestLab Power Electronics is the measurement and characterization of electronic power feed units for industrial customers. The spectrum ranges from solar inverters over battery converters to cogeneration units. Voltage drop tests, feed guideline reviews or efficiency degree measurements represent typical application scenarios. In meetings with customers, our test engineers discuss individual requests and needs and find tailor-made solutions. To retain such a degree of versatility and flexibility, our personnel must be expertly trained, and we must regularly look beyond our own nose.
