Device for measuring parameters relative to e.g. voltage of photovoltaic generator to monitor operation of generator, has variation unit varying load's control signal during maximum measurement time preferably less than ten milliseconds

摘要

The device (1) has a load (2) e.g. transistor, whose impedance varies according to a control signal i.e. continuously varying signal, where the load is connected to terminals of a photovoltaic generator (3). A characteristic determination unit determines a set of current measurements (5) and voltage measurements (6) at terminals of the load for a set of values of the impedance of the load during maximum measurement time. A variation unit varies the control signal of the load during the maximum measurement time preferably less than 10 milliseconds. An independent claim is also included for a method for measuring parameters relative to a photovoltaic generator.
