INVERTER AND METHOD FOR ISOLATING PHOTOVOLTAIC MODULES FROM AN INVERTER

摘要

The invention relates to a method for isolating photovoltaic modules (6) of a photovoltaic assembly from an inverter (1) and to an inverter (1) for converting a DC voltage (UDC) generated in photovoltaic modules into an AC voltage (UAC) with feed lines (11, 12) for connection to the photovoltaic modules (6), wherein an isolating circuit (14), which is formed by mechanical isolating elements (16) in the feed lines (11, 12), for isolating the photovoltaic modules (6) from the inverter (1) is provided. In order to isolate photovoltaic modules (6) in a simple manner even at particularly high DC voltages without the use of correspondingly complex load breakers, at least one load-relief capacitor (17) is provided to relieve the load on the switch-off operation of the mechanical isolating elements (16) during isolation of the photovoltaic modules (6).
