Method and apparatus for the functional and disassembly detection of solar modules

The method involves providing a time randomly varying test signal. A test signal is fed into an electric circuit of a photovoltaic system (2). A reply signal is received from the electric circuit of the photovoltaic system in reaction to the test signal. A characteristic cross correlation function o...

Zusammenfassung:	The method involves providing a time randomly varying test signal. A test signal is fed into an electric circuit of a photovoltaic system (2). A reply signal is received from the electric circuit of the photovoltaic system in reaction to the test signal. A characteristic cross correlation function of the reply signal with the test signal is determined. The deviations of the characteristic cross correlation function are noted. An alarm signal is produced as indication for a disassembly experiment, if the deviations exceed a predetermined threshold. Independent claims are included for the following: (1) apparatus for function and disassembly detection for photovoltaic systems; and (2) inverter.
