Monitoring System
A. Product Description
The PVI-AEC-EVO is a monitoring and checking system for photovoltaic systems made with Power-One Aurora
products.
The product allows to acquire parameters from the inverter and string-comb (in accordance with the design of the
central inverter monitoring system) through the RS485 line with the Power-One proprietary protocol.
The system is equipped with two equivalent RS485 ports and each of them allows a maximum of 62 string inverters
or 62 55kW conversion modules to be acquired.
The system is equipped with three analog inputs for the connection of sensors for the measurement of
environmental parameters:
The system also has six digital inputs for acquiring state signals (for example auxiliary contacts of power switches)
which are associated with state alarm conditions.
With respect to the user interface, the system is equipped with a 2x16 character display and four keys as well as an
integrated webserver with htm pages which are accessible through LAN connection.
The initial system configuration (check that the inverter parameters are acquired, analog inputs configuration, LAN
network parameters configuration) can be carried out completely through the display and keys; for displaying the
detailed parameters of the inverters and/or of the string-combs, as well as for the advanced configurations it is
necessary to access the pages of the integrated web server.
The PVI-AEC-EVO works together with a free web portal service: The system periodically transmits the data to the
portal management server and graphically shows the data on web pages which are accessible through an account
that can be requested from Power-One customer service.
The portal can also be used for sending alarm, report and FW update notification emails: The system FW can be
updated directly through the portal without the need for technical intervention on site.
The FW can also be updated locally without connecting to the portal.
