VSN800 Weather Station
This manual covers the details for installing the VSN800 Weather Station hardware to sense
environmental variables. Through the VSN800 Weather Station, the Aurora Vision Plant
Management Platform can collect and analyze environmental data for comparison to predicted
environmental data and actual inverter/solar panel output.
The RS485 port of the VSN800 Weather Station is attached via low-voltage wires to the
monitoring or management system and communicates information to the management system
using the Modbus protocol. The weather station is powered via 24VDC power, which is
typically available from the data collection hardware of the management system.
Once the hardware is installed, you will need to login to the management system website to
verify the Internet is connected properly and verify that the data in being received.
The VSN800 Weather Station is SunSpec compliant and uses a 2-wire half duplex serial port
for Modbus communication to a host. Contact ABB if you need to modify or program the unit or
change the Modbus address.
