Abstract
A fault detection system in a photovoltaic system 1, is able to identify a system state on the basis of a first and optionally a second measured data profile and is thus able to distinguish error states from the operating state of the system.
Claims27
A method for detecting an electrical fault in a photovoltaic system, comprising the steps of:
- measuring at least a first data profile of a first electrical parameter in the photovoltaic system, in particular in a string of the photovoltaic system;
- evaluating the first measured data profile;
- identifying a system state based on the first measured data profile;
- storing the system state in a state memory;
- retrieving the system state from the state memory;
- and
- issuing an enable signal to solar modules of the photovoltaic system in response to the retrieved system state.
