The procedure for inverter commissioning:
1. conrm all wires are secure
2. conrm PV polarity
3. conrm all covers are installed and secured
4. close (turn ON) the external AC disconnect switch. For the moment, leave the AC disconnect on the inverter OFF.
5. close (turn ON) DC disconnect switch(es).
6. watch for the green “Power” LED to begin ashing a few seconds after the DC disconnect is closed
7. wait for the yellow “alarm” LED to light up and remain on, indicating there is no AC mains
8. close (turn ON) the inverter AC disconnect
9. watch for the yellow LED to turn off, while the green LED continues to ash while the inverter runs self-tests and grid checks. The time required varies from
~30 seconds to a few minutes, depending on the grid condition and standards
10. watch for the green LED to stop ashing remain ON if when self-tests and grid checks are complete and the inverter starts production.
Possible errors
a. Green LED continues to ash - the solar irradiation is not sufcient to power on the inverter
b. Yellow alarm light illuminates - requires debug using Aurora Manager software
c. red “GFI” LED lights - the inverter detected ground leakage current. Turn the inverter OFF, open the disconnect switches and locate the ground fault.

DCWB-2
DCWB-1
For -2 DC wiring box models only, the AFD performs a self-test when the system is started.
- If the self-test results are OK, the inverter will continue to AC grid connection.
- If a potential problem on the AFD board is detected, the self test will result in error E053.
Refer to the product manual (downloadable as described on the cover page) for troubleshooting suggestions.
During normal operation the input current is continually measured and analyzed.
- If a DC arc fault is detected during operation, the inverter is disconnects from AC grid and generates an E050 error code (readable through Aurora Manager software).
- Press and hold the AFD reset button on the left side of the DC wiring box for 3 seconds. This will clear the E050 error and restart the self test.
- If self-test results are OK, the inverter will reconnect to the AC grid; if the DC arc fault is still present, the self-test will result in error E053. Refer to the product manual
online for solutions. The AFD self-test can be manually started anytime using the following procedure:
1. Turn off the inverter (switching off both DC and AC switches),
2. Turn on both the DC and AC switches and wait for self-test result.
If the AFD trips frequently, it means arcs are occurring. Turn the inverter OFF and request service to do complete check of the system wiring, including all connections
and junction boxes, to locate the problem.
This inverter has been factory programmed to automatically disconnect from the utility distribution system in compliance with UL 1741 and IEEE 1547 specications. Default
voltage and frequency trip limit and trip time settings to comply with these standards are shown in table below. Aurora Manager software can be used to adjust Voltage and
Frequency Trip Limit and Trip Time Parameters according to Grid requirements of installation locale. Refer to product manual for instructions on how to use Aurora Manager
software.

Grid support functions
The inverter is equipped with advanced grid support functionality that is useful to support reactive loads and also assist in reliable operation of the utility grid in the
presence of a large number of distributed energy generation sources.
The grid support functions that are equipped on this inverter are described in the following sections.
Aurora Manager software can be used to adjust grid parameters. Refer to product manual for instructions on how to use Aurora Manager software.
An RS485-USB
adapter (not included) is required to modify settings using the Aurora Manager software. The USB driver les and instructions for installation can be found online
at www.abb.com/solarinverters.
This QIG provides an overview of the available grid support functions. For complete details, refer to the technical manual at www.abb.com/solarinverters.
1.Voltage ride-through
This inverter provides parameters to respond to undervoltage and overvoltage events. The inverter is designed to operate normally within the specied operating range.
If voltage excursions occur, the inverter is designed to continue operating normally or cease to export power for a specied delay. Beyond this programmed delay, the
inverter disconnects from the grid in the event of an abnormal voltage condition. The parameters that control voltage ride-through can be accessed from Aurora Manager
software
2.Frequency ride-through
This inverter provides parameters to respond to underfrequency and overfrequency events. If frequency excursions occur, the inverter is designed to continue operating
normally for a specied delay. Beyond this programmed delay, the inverter disconnects from the grid in the event of an abnormal voltage condition.
3.Reactive power modes
This inverter is designed to export active as well as reactive power into the utility grid. The inverter provides several modes of operation for reactive power control and
are described below:
- Disable: This is the default setting. Under this setting, the inverter exports a power factor of 1.0.
- Fixed power factor control (Fixed cos-phi): In this mode, the operator can set the output power factor to a xed value. When enabled, Set percentage will appear on the
display, allowing the setting of the value of Cos-Phi as a percentage from 0.1 to 100.
- Power factor as function of output power (Std cosphi 0.9): In this mode, the inverter reduces the output power as a function of the output power at a given operating
point. The default curve can be modied using the Aurora Manager LITE software program, which can be downloaded from ABB‘s download center web page at http://
www.abb.com/abblibrary/DownloadCenter/.
- Dynamic Volt/VAR control (Std Q(U)): Under this mode, the level of reactive power exported by the inverter is a function of the operating grid voltage, also known as a
Volt/VAR curve. The default Volt/VAR curve can be modied using the Aurora Manager LITE software program.
4.Power reduction
This inverter offers two modes for active power reduction.
- Power limitation: When enabled from the Settings menu, this mode limits the active power that the inverter can export to the grid. The setting is specied as a
percentage of the rated power of the inverter, from 0% to 100% in steps of 1%.
- Frequency/Watt function (Set F Derating): In this mode, the inverter limits the active power as a function of the grid frequency. The default frequency/watt can be
modied using the Aurora Manager software.
5.Ramp controls
The inverter is designed to control the rate at which output power is increased, either at startup, or after a temporary low power condition on the PV array (such as fast
shading). The following ramp controls are provided on this inverter.
- Normal ramp: The normal ramp denes the maximum rate at which the inverter can increase the output power under normal operation. The normal ramp control limits
the dramatic uctuations in the output power in order to prevent instabilities on the utility grid.
- Slow ramp: The soft-start ramp denes the maximum rate at which the inverter can increase the output power when the inverter is rst starting up. This startup may
occur on a daily basis or when the inverter restarts after an abnormal grid event has ended.
