| 摘要 |
The invention relates to a photovoltaic plant having a plurality of inverters (1) connected to each other by way 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), and to such an inverter (1) and a USB mass storage device (11), as well as to a method for carrying out software updates. According to the invention, 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. |
