The Photovoltaic Laboratory (PV Lab) at BFH is involved in the measurement of PV inverters since nearly 30 years. In the first years after 1988, stationary PV installations were used. On the new laboratory building in Burgdorf, a flexible 60 kWp PV plant allowed a wide range of measurements [1]. However, this is not very practical. For this purpose, four linear, high-speed PV array simulators with high stability (12 kW, 20kW, 25kW & 100kW) have been developed. In 2015, a new multistring-simulator with 3 x 11,5 kW was built. These projects were partly supported by the Swiss Federal Office of Energy SFOE. In 2014 we started a project for the accreditation of the PV inverter test bench. Based on the quality management system QM-Pilot, which is standard at BFH, we could establish the processes. In September 2017 we got the accreditation for PV inverters. It gives the industry and the researchers qualified test processes for their measurements. The project efforts were mainly supported by the Swiss Federal Office of Energy SFOE. Further support was given by the Swiss Competence Center of Energy Research for future grids (SCCER-Furies) and the Berner Fachhochschule Technik und Informatik BFH-TI
