In spring 1994, a new test centre for PV-systems with a PV generator of 60 kWp became operational. With this test centre, tests of medium sized inverters up to 30kW are also possible. A significant extension of the testing facilities was possible with the introduction of solar generator simulators. Several PV generator simulators up to 25kW with high stability were developed in 1998 to 2000 (one of them computer controlled). With these simulators, partly automatic inverter tests can now be carried out much faster. In this paper at first a short overview of the concepts used in grid connected PV inverters is given. Then the most important test results of all inverters tested (more than 28) will be displayed, which clearly shows the considerable progress achieved in the last years. The evolution of different important properties of PV inverters will also be discussed. Results of intense tests of some recently developed inverters used in many grid connected PV-systems will be used to illustrate some interesting cases or typical performance of new inverters. Reliability of inverters will considered using monitoring data of more than 45 PV plants continuously monitored since 1992
