SINVERT PVS in power plants18
Communication via Industrial Ethernet and plant monitoring by means of SINVERT WebMonitor
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.
SINVERT PVS ComBox 200
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
