Aurora Environmental Appliance
Installation Guide
Models VSN-ENVIRO-CMML
and VSN-ENVIRO-ENTRY
This installation document covers the details for installing the Aurora Environmental Appliances (AE-
Commercial and AE-Entry) hardware to sense environmental variables. Through the Environment
Appliance, the Management System (for example, Aurora Vision Prime Edition) collects and analyzes
environmental data for comparison to predicted environmental data and actual inverter/solar panel
output.
The RS485 port of the Aurora Environmental Appliance 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 Aurora Environmental is SunSpec compliant and uses a 2-wire half duplex serial port for Modbus
communication to a host. Contact Power-One if you need to modify or program the unit or change the
Modbus address.
