1SYSTEM OVERVIEW
The Aurora Logger is a lightweight solution for remote data acquisition, which enables PV system
owners to benefit from advanced energy reports. The Aurora Logger collects and analyzes energy
generation data from all connected Power-One inverters and optional weather station for
commercial loggers. System performance and energy information are logged into a database on
the Information Server, where it can be retrieved and used for analysis via any standard web-
browser.
The Installer logs on to the website to register the Aurora Logger and ensures that the logger is
correctly passing information to the servers. The Installer provides a URL to the end user for access
to Aurora Easy View.
Aurora Logger in conjunction with the Aurora Vision solution brings the following benefits:
•Safeguard Your Investment and Maximize Your Return
•Improved Solar Energy System Efficiency
•Lower Life Cycle Costs
•Real-time and Historic Data Presented Using Web-based Devices
•Alarm Functions and Device Communication Failure

2INSTALLATION
Qualified personnel with appropriate training and experience must perform Aurora Logger
installation. Follow standard safety precautions during all procedures. Appropriate personal
protection equipment (PPE), such as safety gloves and safety glasses is recommended.
WARNING!
During normal operation of the Aurora Logger, dangerous voltages flow through many parts of
the system, including: terminals, all I/O Modules (Inputs and Outputs) and their circuits. All
Primary and Secondary circuits can, at times, produce lethal voltages and currents. Avoid contact
with any current-carrying surfaces.
2.1 PREPARATION
Make sure you have the following tools and materials prior to starting installation.
Tools
•Standard Electrician’s Toolkit
•Personal Protective Equipment (Gloves, Goggles, Clothing)
Materials and Test Equipment
•Twisted-Pair RS-485 Wire (Belden#3106A or eq.).
DO NOT USE CAT5/6 CABLE FOR THE RS-485 DATA WIRE.
•Ethernet Cable to make Network Connection
•Laptop Computer with Internet Browser
•Second Ethernet Cable for Logger configuration
•Mounting Screws and/or Brackets
It is also useful to know if you need to perform Asset Registration or final End-to-End Data Checks
after physical installation is complete. If so, you will need a User ID/password to log in to Aurora
Vision, and additionally you will need Administrator privileges to access the Aurora ADMIN tool.
See the Commissioning section for details.
2.2 AURORA LOGGER INSTALLATION
1. Check packaging for all components:

Aurora Logger

Power Supply Adapter

8
2. Determine the indoor location of the Aurora Logger. For reliable operation, it is required
that the data logger be located within 100m (330 ft.) of an Ethernet connection and
within 1200m (4000 ft.) of the inverter(s).
3. Mount the Aurora Logger. The Aurora Logger comes with flanges with pre-drilled holes
for easy mounting. All Aurora Logger versions require a weather protected site. The
included power supply requires an ambient temperature between 0oC and 40oC but the
logger can operate between -40oC and 85oC.
4. Connect shielded twisted-pair wire to the RS-485 terminals on the inverter(s).If there are
multiple Power-One inverters, wire the inverters in a daisy chain configuration. Use a RS-
485 data wire with one twisted pair, one ground conductor, and a shield with drain wire
(Belden#3106A or equivalent).
DO NOT USE CAT5/6 CABLE FOR THE RS-485 DATA WIRE.
5. Connect other end of shielded twisted-pair wire to Secondary RS-485 terminals on the
Aurora Logger. Use the table below and the figure on page 10 to make the proper
connections.

7. Connect other end of shielded twisted-pair wire to the Primary RS-485 terminals on the
Aurora Logger. Use the table below and the figure on the next page to make the proper
connections. See Section 4 for more information on wiring the optional weather station
to the Aurora Logger.
RS-485 Screw Terminal
8. For systems with multiple Power-One inverters, the RS-485 network must be terminated
at the final inverter by a switch near the RS-485 terminal block. The farthest inverter in
the daisy chain must be terminated by setting the inverter termination switch to ON. For
all other inverters in the daisy chain, turn OFF the termination switch. Below are pictures
of RS-485 terminals in various Power-One inverters, as well as locations of the
termination switch.1If you need more information, consult your inverter’s manual for
locating the RS485 terminals and the termination resistor switch.
1In some environments you may experience poor RS-485 signal strength due to noise. If signal strength is a problem,
double-check that the last inverter in the chain is terminated and other inverters are not terminated. If problems
persist,itmay prove helpful to attach a 120 Ohm 0.5 Watt resistor across screwterminals 1 and 2 on the Aurora
Logger.

9. The Power Adapter comes packaged with your Aurora Logger with the DC output wires
pre-stripped and tinned for connecting to the Screw Terminal of the Aurora Logger.
Attach the conductor with white label, which is a positive +12 VDC cable, to Port 6 of the
Aurora Logger Screw Terminal. Attach the other solid black ground conductor to Port 5 of
the Aurora Logger Screw Terminal. See the figure below.
10. Connect the supplied power cord to the Aurora Logger and a standard power outlet. The
power supply is a universal power supply so it can be used worldwide and will come with
a plug adapter that is specific for your region.
11. Check the Aurora Logger power. There is a pair of light emitting diodes (LEDs) on the side
of the logger, opposite the RS-485/DC power terminal block. The LEDs flash red during
system boot and then one turns solid green when power is supplied and the system is
ready.

2.3 POWER ONE INVERTER ADDRESS CONFIGURATION
Power-One inverters use a proprietary RS-485 communication interface, and therefore must be
daisy-chained to the Secondary RS-485 terminal connectors. For system with multiple inverters,
each inverter must be manually assigned a different RS-485 address. Refer to the inverter
manual(s) for instructions on how to set inverter addresses and exact inverter connection
points. Write down the serial number and RS-485 address for each inverter so you can
determine which inverter is which on the monitoring system.

12
3COMMISSIONING
The following are the major steps required to make sure the system is operational and data is being
passed to Aurora Vision servers:
1. Connect the Aurora Logger (data logger) to your Ethernet network.
2. Run the Aurora Logger Setup Tool to verify that your Aurora Logger is configured properly.
The Setup Tool is the built-in web server of the logger.
3. Verify that you have a working Internet Connection to the Aurora Logger.
4. Perform Asset Registration using the Aurora ADMIN tool over the Internet.
5. Verify end-to-end data transfer using the Aurora Vision web portal.
Commissioning is not complete until you have performed the final two steps above over the
Internet. However, these two steps do not necessarily need to be performed as part of the
hardware installation.
3.1 CONNECT TO THE INTERNET
Connect the Aurora Logger to the Internet through the local area network or directly. This is done
by using a standard Ethernet cable (CAT-5/5e/6/6a) and connecting it to the Ethernet RJ-45 port
marked Eth0 on the front of the Aurora Logger. The Aurora Logger can connect through any switch
or router in your network.
Verify that the Aurora Logger has an Ethernet connection. The Eth0 LED can be used for detecting
network link and network traffic:
•Eth0 LED = GREEN = Link
•Eth0 LED = GREEN BLINK = Traffic
•Eth0 LED= OFF = No network link
If no activity is seen on the LEDs, double-check all connections.2
Power-One recommends a wired Ethernet Internet connection because it is more reliable and
requires less setup. If it is necessary to connect to a wireless network, a wireless network bridge
with an Ethernet port is required. Purchase and configure the wireless network bridge that is
compatible with the host wireless network. Ensure that the wireless connection is operational with
a laptop before connecting it to the Eth0 port of the data logger.
Power-One does not provide Internet service or the cables required to connect the Aurora Logger
to the Internet.
2The Aurora Logger is bydefault set to DHCP and will try to acquire its IP-address from the DHCP s erver on your l ocal network
(LAN). The Aurora Lo gger i s designed for use o n a n Ethernet network a nd must b e assigned a n IP a ddress (DHCP or s tatic) to ma ke it
a ccessible. I f it is required to set a static IP for the Aurora Logger, your connection willnot work until this address is set. If required,
refer to the section below on setting a Static IP address. Normallyno ports should need to be opened in the network firewall. The
Aurora Loggerwill useport 443 outbound to transmitthe data and port 53outbound to resolvedomainnames.

13
3.2 RUN THE SETUP TOOL
The installer must use a laptop with an Ethernet cable to communicate directly to the Aurora
Logger and run the setup tool. The setup tool has many options and capabilities, but here we will
only describe those necessary to get your system up and running.
1. Configure the laptop’s Ethernet port to obtain a Dynamic IP address automatically through
DHCP; typically, laptops are already configured this way.
2. Connect the Ethernet cable between the secondary Ethernet port marked Eth1 on the
Aurora Logger and the laptop computer.
3. Open up an Internet browser window on the computer and type in the following URL in the
address bar.
http://172.17.17.1
4. The following Home page will appear:
Select the tabs across the top to perform configuration operations and select one of the ports in
the Devices list to set up devices.
Verify all the icons for the Aurora Logger in the status area to the right are green. It may take some
time for all the icons to turn green.
The MAC address (Logger ID) for the Data Logger is displayed at the top of the page. Be sure to
write down the MAC address of the Data Logger. The MAC address will be needed later for Asset
Registration.

14
3.3 CONFIGURE FOR INVERTER DEVICES
The Devices list on the Home page will show all the different devices connected through all the
ports on the Data Logger. It is essential that the devices you set up here match how devices are
physically connected to your Aurora Logger.
By default, only the two RS-485 ports are set up. The primary RS-485 port is set to Modbus RTU
and the secondary RS-485 is set to Power-One Aurora Protocol. The default supports hardware
connections where all Power-One inverters are attached as an RS-485 daisy chain and connected to
the Secondary RS-485 port. Optional weather stations used with the Aurora Logger Commercial are
connected to the Primary RS-485 port. See Section 4 if you are adding a weather station. See
Section 5 if you are using an Aurora Logger Max.
For the Secondary RS-485 connection, once Power-One inverters are properly addressed and wired
in the RS-485 daisy chain, inverters will automatically be discovered and displayed.
3.3.1 SET A STATIC IP ADDRESS
Setting a Static IP is only necessary if required by your network. In almost all cases you can skip this
section.
1. Obtain Static IP address information for the site.
2. Select the Network tab. Set the Type (Network Connection Type) field to Static. The page
will allow you to type in the following information:
•IP address
•Subnet Mask
•Gateway
•DNS (separate primary and secondary DNS servers with a single space)
3. Press Update at the bottom of the page.
The Aurora Logger will need to be restarted before the network changes take affect. In the Home
tab use the Reboot Logger button to reboot the logger.
3.4 VERIFY INTERNET CONNECTIVITY
1. Verify that the Ethernet cable is connected between Eth0 and your network.

15
2. The Aurora Logger acts as a router. From your laptop connected to Eth1, verify your
internet connectivity by opening up an Internet browser window and connecting to an
Internet address, such as www.auroravision.net.
3. Remaining steps for commissioning are performed via the Internet to check end-to-end
communications. Proceed with one of the following steps:
a. If you are not responsible for these remaining steps, be sure to pass on the MAC address
(Logger ID) information to the responsible party. Remove the cable from Eth1.
Installation is complete.
b. If asset registration is already complete, proceed to the section on End-to-End Data
Check.
c. If asset registration is not complete, proceed to the next section on Asset Registration.
3.5 ASSET REGISTRATION
Asset registration is performed via the Aurora ADMIN Web tool. Asset registration assigns the MAC
address of your logger to a specific plant in Aurora Vision. Asset Registration can be performed
before or after the on-site installation is complete. When you register the Aurora Logger, all the
assets (inverters) reporting data to the Aurora Logger are also registered. The plant must be
created as an asset using Aurora ADMIN before the Aurora Logger can be assigned and registered.
From the Setup Tool, follow the link to the Asset Registration page of Aurora ADMIN. If you are not
running the Setup Tool, go to https://admin.auroravision.net/customeradmin. Select
Services > Asset Registration and type in the MAC address of the Aurora Logger. The Asset
Registration page allows you to select the plant that the data will be associated with. Note that use
of the Aurora ADMIN tool requires a User ID and password with Administrator privileges.
Select the Services > Asset Registration page in Aurora ADMIN to register the logger. Go to
https://partner.auroravision.net/display/en/Asset+Registration on the partner portal for
help in using the Aurora ADMIN tool for asset registration.
3.6 END-TO-END DATA CHECK
The last check is to make sure that data is actually being reported and is visible in the Aurora Vision
portal. Wait 15 minutes and log on to www.auroravision.net using a web browser on an Internet
connected device. Within Aurora Vision, go to Assets > Summary page for the plant and open the
Device Status panel. Verify that the energy readings agree with the inverter and that all of the
monitored devices are communicating, as indicated by the Last Reported time.
3.7 AURORA EASY VIEW ACCESS FOR END USER
The installer must supply the user with the Easy View URL so they can access Aurora Easy View and
monitor their system. To find the URL for a specific user site within Aurora Vision, follow these
steps:
1. Log on Aurora Vision at www.auroravision.net and go to Assets > Details.
2. Select the asset from the asset list in the screen area to the left.

16
3. Once the correct asset is displayed, select Share from the Actionsmenu.

17
4. A page displays to configure the Easy View display options. Scroll down to the Published
View section. The URL to provide to the customer is in the Share URL field.

18
4ADDING A WE AT HER STAT I O N
Weather stations are wired to the Primary RS-485 port on the Aurora Logger Commercial and MAX
versions. Weather stations are not supported for the Residential model.
1. Connect shielded twisted-pair wire to the RS-485 terminals on the weather/environmental
station. Use a RS-485 data wire with one twisted pair, one ground conductor, and a shield
with drain wire (Belden#3106A or equivalent).
DO NOT USE CAT5/6 CABLE FOR THE RS-485 DATA WIRE.
2. Connect other end of shielded twisted-pair wire to the Primary RS-485 terminals on the
Aurora Logger. Use the table below and the figure on the next page to make the proper
connections.

3. The weather station can tap the power terminals on the Aurora Logger for its power source.
Using the Aurora Logger as the power source is optional; any appropriate DC power source
that meets the specifications of the weather station may be used. To use the Aurora Logger
as the power source for the weather station, connect shielded twisted-pair wire to the
power terminals on the weather/environmental station. For distances less than 400 feet
between the Aurora Logger and the Aurora Environmental weather station use #22 AWG
stranded copper wire. For longer distances use a heavier gauge wire. Consult the Weather
Station’s datasheet for the minimum required voltage and maximum allowed wire gauge. If
unable to meet these specs because of voltage drop then a separate power supply closer to

The port configuration for the Primary RS-485 port on the Aurora Logger Commercial must remain
set to Modbus RTU (default value). Configuration of the Primary RS-485 port only needs to be
completed when using an optional weather station.
Configure the Primary RS-485 port using the following procedure. Bring up the Setup Tool in the
same manner as for configuring inverters (connect Aurora Logger directly to a laptop and go to
http://172.17.17.1).
To add the Power-One Environmental weather station go to the Home tab and push the FIND
button for the Primary RS-485 port. The logger will discover and add the weather station. For the
VSN-ENVIRO-ENTRY and VSN-ENVIRO-CMML weather station models the default Modbus address
is 60.
