Photovoltaic arrangement, has evaluation and control device grounds direct-current-side of solar inverter and solar system when measuring unit identifies feeding to solar inverter such that pole of solar system is placed on ground

摘要

The arrangement has a solar system (1) comprising a solar module and a solar inverter (4), which converts direct-current (DC) supplied from the solar system into alternating-current (AC) for a power supply network. A measuring unit (6) i.e. clamp-on ammeter, recognizes a feeding operation of the solar inverter. An evaluation and control device (7) grounds a DC-side of the solar inverter and the solar system when the measuring unit identifies the feeding to the solar inverter such that a positive pole (2) or a negative pole (3) of the solar system is placed on the ground. An independent claim is also included for a method for operating a photovoltaic arrangement.
