Integration of SINVERT PVS inverters into a photovoltaic plant without solar PV plant control with communication via an Ethernet network and monitoring by means of SINVERT WebMonitor

In the configuration example shown in the diagram without solar PV plant control and with plant monitoring by means of SINVERT WebMonitor, the required industrial PC is provided in the SINVERT PVS ComBox 200, which must be used in one of the inverter stations instead of a ComBox 100.

SINVERT PVS ComBox 200

The SINVERT PVS ComBox 200 has the same scope of functions as the ComBox 100, but also provides the capability of transfer- ring data from the SINVERT PVS inverters and from additional network-capable components to the SINVERT WebMonitor web application for monitoring photovoltaic plants.

The ComBox 200 contains the following main components:

–4 x RJ45 ports

–2 x fiber-optic ports, for cable lengths up to 5 km

Weather station

The SINVERT PVS WeatherStation 200 acquires data about the weather at the photovoltaic plant site. This weather data is recorded by sensors connected to the station. The following sensors are included in the scope of supply of the WeatherStation 200:

–Insolation

–Module temperature

–Ambient temperature

Additional sensors such as wind speed or rain sensors can be connected.

Using the acquired data, it is possible to perform and transmit extremely precise weather recordings. The target yield of the photovoltaic plant can then be calculated from the recorded weather data. By comparing the actual and target yield, it is possible to make a quick assessment of the plant's operating performance and detect any irregularities very promptly.

The SINVERT PVS WeatherStation 200 offers the following connection options:

–6 analog inputs for the sensors

–PROFINET communications interface
