Wiring Recommended shielded twisted pair, 20 AWG, with 120Ω impedance (Belden 3106A or equivalent)

Up to 5 Power-One inverters

Single Phase Inverters ONLY

Residential Installation (example)

Secondary RS485 is default set to Aurora Protocol

• Depending on the type of computer used, the cable line adaptor can be RS485-RS232 or RS485 to USB.

Activate the termination resistor in the LAST inverter on the communication line by switching the dip-switch inside the inverter

Data Communications: Addressing the inverter

Etc.

Address each inverter differently

Under the “Settings” Menu

For Multiple inverters on same communications line:

Select “Address”

Maximum of 32

Should not be set to “AUTO”

What about these handy RJ45 jacks?

• It is possible to use both, ex. -

• CAT 5: Inverter-to-Inverter

• Hardwire: Inverter 1-to-D. L.

• Use Shielded CAT 5

• Minimize Distance

• Test all jacks & crimps

All are internally connected

Less Robust long-term

Aurora PVI-RS485-Modbus adapter translates from Aurora Protocol to Modbus RTU protocol

Converting P1 Protocol to MODBUS

Power-One Inverters utilize a proprietary Aurora Protocol over the RS485 link

Things to Consider before Site Visit:

Any Ethernet based Internet connection

– Cable, DSL, Satellite

Contact administrator if necessary

Needs standard 100-240VAC

Within 300 feet (Ethernet limit) of internet connection

Location of Data Logger

Aurora Vision account set up

Determine internet connection

Determine Network Security

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.yahoo.com.

Possible Issues on Connection and Commissioning Logger

Data Transfer: Check firewall protect, internet connectivity, contact site network administrator. Possibly need to set up Static IP address

Credentials: Call Power-One Tech Support

Server Login: Ensure network Connectivity

34

Setting a Static IP Address:

Most sites will not require this, usually

more secured locations.

Select TYPE: Static from drop-down menu

Obtain Static IP information from Site network administrator

Go to the “Networks” tab on the local interface

Enter required information and click “Update”

Commission Data Logger

Should automatically detect inverters and devices. “Refresh” your browser if not detected.

If inverters still are not detected, check the MODBUS address in the inverter menus, wiring, and termination

resistor switch positions inside the inverter.

Add Modbus RTU Devices

Select the “Slave ID”

(This is specific in the user manual)

To non-Power-One or devices such as weather stations and

Metering:

Select the device type from the drop down menu

Enter a description to identify the device

Logger Registration to Aurora Vision

IF Plant is already set-up on Aurora Vision website, then simply click on the

Logger Registration tab to directly go to

If Plant is not already set up, go to Aurora Vision website

and Create a new plant.

Aurora Vision

• Can be done through Power-One support as well • First user for each organization is the

“ADMINISTRATOR” – ADMINISTRATOR privileges allow the user to

create new plants, users, etc.

(This can be done before, during, or after the installation)

• Installer sets up logger & plant/site on Aurora Vision admin

Information needed:

• Location of site

• MAC address of logger
