2 TRIO 20.0/27.6-TL-OUTD-US-480 | Programming for HECO compliance
1. Introduction
This instruction provides the method to reprogram the ABB TRIO-20.0/27.6-TL-OUTD-X-US-480 to the Hawaii Electric Company,
Inc. (HECO) ultra-fast trip transient over-voltage requirements (TrOV-2) and frequency voltage ride through (FVRT) mitigation
requirements as described in the document “Appendix IIA Full Ride Through Settings for O’ahu, Maui, Hawai’i” dated January,
2015. Details of these requirements are available on the HECO website at: http://www.hawaiianelectric.com/vcmcontent/
StaticFiles/pdf/TrOVandFVRT_Public_Feb2015.pdf.
Every operation performed on the TRIO-20.0/27.6-TL-OUTD-X-US-480 shown in this instruction must be
performed following existing regulations and safety instructions and carried out in compliance with the
instructions provided in the product manual located at http://www.abb.com/solarinverters/.
2. Parameter setting via inverter’s display
HECO requirement settings can be set via the TRIO’s LCD display using the service menu (accessible using the buttons on the
inverter’s LCD panel) as shown in Figure 1 below. Note: to obtain the second level password, call ABB solar inverter post-sales
technical support at 1-877-261-1374, 6 a.m. - 6 p.m. MST.
After entering the second level password, the list of inverter grid parameters can be accessed using the UP and DOWN buttons.
Once the parameter indicated in the center column (Inverter parameter) of Table 1 below is highlighted, press ENTER. Then, use
the UP/DOWN buttons to increase or decrease the parameter’s value. Select the new setting value shown in the right column.
Once all settings have been changed, press ENTER to confirm.

3. Parameter setting via software tool Aurora Manager Lite
Aurora Manager Lite is a free ABB software which communicates with the ABB TRIO inverter by reading the inverter data, settings
and sending commands. Contact ABB solar inverter post-sales technical support at 1-877-261-1374 to obtain the software and
any required password.
To use the Aurora Manager Lite software, it is necessary to connect a laptop PC to the inverter. The computer must communicate
through an RS485 line using an RS485-to-USB adapter. ABB recommends the ABB Aurora Adapter in order to avoid compatibility
issues; however, equivalent devices may be used. For details connecting the ABB Aurora Adapter to the inverter, refer to Appendix
A: How to connect the laptop PC to the inverter on page 6 of this instruction.
For the procedure to access the Aurora Manager Lite software, refer to Appendix B: How to launch Aurora Manager LITE on page
7 of this instruction.
When multiple TRIO inverters are daisy chained, it is possible to change the parameters on all inverters connected in the chain at
one time. Once the laptop PC is connected to the daisy chain, Aurora Manager Lite will scan for all inverters and list each by model
and serial number on the left side of the screen. Verify that each inverter in the daisy chain is identified in the list. Refresh the list if
necessary. All inverters in the daisy chain must be set to communicate through Aurora Protocol. If set to Modbus, each inverter will
need to be changed to Aurora Protocol or individually updated to HECO parameters.
Once the laptop PC is connected to the inverter, click on the Setup tab as shown in Figure 2 below.

Next, click on the AC side tab, then the Grid protection tab, as shown in Figure 3 below. Voltage and Frequency grid parameters
are all now accessible.
To set the HECO parameters outlined in Table 1 on page 2 of this instruction, the boxes in the New columns must be changed as
shown in Figure 4 below:

Rather than changing the settings for each individual TRIO inverter in a daisy chain configuration, select Apply setup changes to
ALL connected units at the top of the screen, as shown in Figure 5 below.
