The invention relates to a photovoltaic system (PVA) for feeding into an electrical network (SN), which several solar inverters (M1-M4), the output side feed into the electrical network, and a plurality of photovoltaic generators (SM1-SM4), each at an input side a solar inverter are connected. A communication bus (BUS) connects the solar inverters in terms of data technology, whereby a central control and monitoring device (MAS) is provided, which is likewise connected to the communication bus for controlling and monitoring the solar inverters and has a grid monitoring device (ENS) which predetermines the solar inverters in case of non-compliance Grid monitoring criteria at least temporarily shuts off. The big advantage is that a central control and monitoring device takes over the exclusive network monitoring. As a result, a mutual influence of the otherwise modular solar inverter with its own network monitoring device is avoided. Unnecessary shutdowns of individual solar inverters are avoided.
