Grid-connected inverters for photovoltaic (PV) energy systems areexamined for various aspects. This report describes tests additional to those described in a previous report (ECN C-94-50; Comparison of Six Inverters). The main goal of the extra tests is to determine the susceptibility of grid connected PV-inverters to a broad range of disturbances which can occur on the power grid lines. These noise voltages can be caused by environmental influences such as: atmospheric discharges, flash of lightnings, noise radiated by nearby equipment, or even power grid failures. At ECN the test facility for PV-inverters is expanded with equipment that can be used for these tests. The following extra equipment is available: mains control signal generator; variable frequency and voltage test bench; power failure system; burst generator; and a surge generator. 56 figs., 6 tabs., 5 refs.
