Patent ID: 8645937

Claim:
A photovoltaic plant having a plurality of inverters ( 1 ) connected to each other by means of a network ( 12 ), wherein the inverters ( 1 ) comprise a control apparatus ( 7 ) having at least one microprocessor ( 8 ) and at least one storage, an interface for communicating with the remaining inverters ( 1 ), a DC/AC module ( 3 ) for converting a direct current supplied from an external energy source into an alternating current, and an input/output unit ( 9 ), wherein a USB interface ( 10 ) is arranged on at least one inverter ( 1 ) for connecting a USB mass storage device ( 11 ), in particular a USB stick, so as to carry out automatic updates in a software running in the microprocessor ( 8 ) and/or configuration block updates and/or so as to record logging data of the inverters ( 1 ), wherein the inverter ( 1 ) connected with the USB mass storage device ( 11 ) is designed for automatically assuming the function of a master in the network ( 12 ), so that the data available in the USB mass storage device ( 11 ) are adapted to be distributed also to all remaining inverters ( 1 ) in the network ( 12 ) and the software and configuration blocks thereof are adapted to be updated in the same manner.
