  • Method for theft recognition on a photovoltaic unit and inverter for a photovoltaic unit
    Patent number: 8466789
    Abstract: The invention relates to a method for recognition of the theft of at least one solar module (5) on a photovoltaic unit with an inverter (1) an intermediate circuit (3), a DC-AC converter (4), at least one solar module (5) connected via connector lines (19) and a control device (8). A signal unit (19) which can be connected to the connector lines (9, 10), for generating and transmitting an electrical signal and a device for measuring and analyzing the signal received from the at least one solar module (5) are provided such that conclusions can be drawn about the theft of a solar module (5) from the received signal. According to the invention, reliable recognition of theft of a solar module (5) can be achieved by designing the signal unit (19) for generating varying electrical signals.
