Abstract: The present disclosure concerns a state monitoring or diagnostics system, and also a method for monitoring the state of devices or for diagnosing devices, in particular for overvoltage protection devices, as well as a method for transmitting measured values. Each of the devices comprises a functional component to be monitored and a monitoring and transmitting apparatus, wherein the monitoring and transmitting apparatus consists solely of a resonator circuit made of passive electrical components with no microchip, in particular with no RFID transponder. The information to be interrogated resides in the resonant frequency of the resonator circuit.

Abstract: The invention concerns a PV system in which a multitude of PV modules are interconnected to PV generators. Each of the PV modules comprises a network interface for transmitting module-specific data to a control device and analyzing the same. The data network is designed as a self-organizing network, in particular as a self-organizing meshed radio network.
