Abstract

The present invention relates to a method for monitoring photovoltaic modules (1, 2), which are used in an arrangement comprising several photovoltaic modules, which are connected in particular in series by means of electrical conducting means (3), wherein a separate microcontroller (5) is associated with the respective photovoltaic module (1, 2), an in particular continual determination of at least one status parameter of the respective photovoltaic module (1, 2) is performed by the microcontroller (5), the data concerning the status parameter are transmitted to an evaluating unit (10), the data intended to be transmitted to the evaluating unit (10) are designed in the form of data blocks (7, 8), the electrical conducting means (3) present for connecting the individual photovoltaic modules (1) are used to transmit the data blocks (7, 8), and the data blocks (7, 8) are transmitted independently of each other so that the probability of data blocks (7, 8) colliding with each other is greater than 0.

Description

technical field [0001] The invention relates to a method for monitoring individual photovoltaic modules in a device comprising a plurality of photovoltaic modules, a photovoltaic module and a device for generating electric current. Background technique [0002] One such method has been disclosed in DE10136147B4. The method includes, as an integral part of each solar module, a module converter (Modulkonverter) with several mutually separated sensors for measuring specific properties of the solar module, such as DC voltage, DC current, temperature or vibrations (Erschütterung). The measured values ​​are fed as an analog signal to a microprocessor, which converts the analog signal into a digital signal and feeds the actual value to a power conditioner connected to the busbar. This known method has the disadvantage that it is complex and expensive for the required installation. Contents of the invention [0003] The technical problem to be solved by the present invention is...
