Preparing Inverters for Connection to Aurora Universal
Inverters must be connected to each other in a daisy chain before being connected to Aurora
Universal. The RS-485 serial port uses a three-wire cable, two wires are for signals and a third one
for ground connection. RJ12 ports and appropriate cabling can serve as the connection between
inverters. (I assume it would be OK to use the RJ12 connectors between inverters and use RS485 to
Auurora Universal?)
1. Install the Power-One Aurora inverter(s) as per the inverter documentation for the
inverter model you are working with. Adhere to all cautions and safety instructions in
the Power-One Aurora Inverter manual and the proper tools to remove the access
panel.
2. Verify the first (or only) inverter address. Make sure the first (or only) inverter
address is set to 2 (the default). For detailed information on configuring addresses,
refer to the section on "address selection" in the inverter installation manual. If you
have only one inverter, stop and proceed to the next section.
3. If more than one inverter is used, configure each additional inverter address,
incrementing by 1. For example, in the case of three inverters, the first address
would be 2, and the next two inverter addresses would be 3 and 4. For detailed
information on configuring addresses, refer to the section on "address selection" in
the inverter installation manual.
CAUTION!
FST uses the inverter address to track data for each inverter and to establish the Web site view.
Once the inverter is connected to the FST monitoring equipment and is reporting data to the
FST server, the address may not be changed without incurring additional expense to the
customer.
If the address must be changed at a later time or an inverter is replaced, FST Technical Support
must be contacted before the change is made.
If for some reason the inverters cannot be configured as specified, FST Technical Support must
be contacted before service is started.
