AC output connections
AC output overcurrent protection is not provided with the inverter; it is the responsibility of the end user to provide overcurrent protection for the AC output circuit.
To prevent electrocution hazards, all the connection operations must be carried out with the external AC disconnect switch downstream of the inverter (grid side) open
and locked out.
Size conductors per NEC Article 310; Use 90°C copper wire only; terminal
block accommodates wire size range of 14-4 AWG.
The AC grid wiring is connected through the
inverter switchbox.
•
Run an approved raceway between inverter
and external AC disconnect switch.
•
Make conduit entry through openings
B
or
E
shown in section
4
.
•
Connect AC wiring to switch box terminal
block
J
and the main AC ground cable to
switchbox terminal block
K
shown at left.
•
Table at right shows AC wiring connections
based on the AC grid type, (also found on a label
in the switchbox).
•
connect wiring to the numbered terminals
based on selected grid type.
The default 240V-SPLIT-PHASE connection requires the grid Neutral to be connected for proper operation. Before connecting the inverter to the grid, the grid type must
be selected if it differs from the default 240V-SPLIT-PHASE setting. See Section 10 for instructions to change the default. If several inverters are installed to a three-phase
AC GRID, always distribute the inverters between the phases in order to reduce power imbalance between the phases.
7.
Communication wiring
Wiring for the RS-485 communication system and hardwired control options are routed through the switchbox (section
4
) and into the main inverter chassis for termination. Alarm and
monitoring connections are shown as items
Q
and
R
.
Refer to the technical manual online for connections to ALARM (Q) and Rem (remote control).
The WIND terminals (±WT ) are not isolated and can have hazardous voltages pres-
ent. These terminals must not be utilized for any purpose in a PV installation (use
with wind models only).
To connect the communication wiring, it is necessary to open the inverter cover and access the
communication connections located on the main board.
•
T o remove the front cover of the inverter compartment, loosen the four captive screws
indicated using the Torx screwdriver provided.
•
When connection operations are complete, re-install the front covers and tighten the
cover screws with at least 1.5Nm (13.2 in-lbs) torque to ensure proper waterproof
sealing.
The RS-485 communication line connects the inverter to the monitoring devices and may be
“daisy-chained” (in-out) among multiple inverters. The RS-485 connecting cables can use both the
terminal connections
R
, as well as the RJ45 connectors
S
, to connect to the dedicated port.
If a daisy chain connection is required for AFD installed inverters (-A models) use standard
multiconductor RS-485 cable and connect the three RS-485 leads (-RTN, +T/R,-T/R)
USING ONLY THE MATING CONNECTORS.
Do not use RJ45 connectors with AFD installations.
RS-485 connectors
(R)
•
If terminal blocks are used, signals RTN, +T/R and –T/R have to be cabled.
•
Use a cable designed for use with RS-485 communications.
•
Locate mating connectors (provided in hardware bag) for the terminal block.
•
Connect the three (-RTN, +T/R, -T/R) to the mating connector corresponding points.
•
Attach mating connector to line up with correct signals on either upper or lower terminal
rows (two parallel terminals rows are on the terminal block and two mating connectors
are included).
RJ45 connectors
(S)
•
RJ45 connectors (1) and (2) available for the RS-485 communication are equivalent to
each other and can be used interchangeably for input or output of the line to create the
daisy chain connection of the inverters.
•
Do not use RJ45 connectors with AFD installations.
Daisy chain connection
•
Recommended length of total communication cable line for all inverters in
the system is 1,000 meters [1094 yards] or less.
•
Depending on type of computer used, cable line adaptor can be RS-485-
RS232 or RS-485-USB.
Termination switch
(S2)
•
On the last inverter in a daisy chain, or on a single inverter, activate
termination resistance by moving switch S2 down into the ON position.
•
All other inverters in daisy chain will have the switch up in the OFF
position.
Addressing each inverter
•
Default setting for RS-485 address is 2 and termination switch in OFF
position.
•
When multiple inverters are connected in a daisy chain, it is necessary to
assign a different RS-485 address to each unit.
See
section 10
for instruction on using the display to configure settings.

When multiple units have been connected in a daisy chain, the individual address will need to be assigned
prior to grid connection
using the display menu. The grid default type,
240V Split Phase, can also be changed
prior to grid connection
using the display menu.
With only the array connected, set the inverter’s DC disconnect switch to ON. GREEN POWER LED will flash and YELLOW ALARM LED will be steady. The LCD will read
“Missing Grid”
. Press ESC to open the menus. Use the DOWN key to scroll to
Settings
, and press ENTER.
The Settings menu requires an access password.
Upon selecting
SETTINGS
the password screen will display; the default password is
0000
.
Pressing ENTER four times loads four zeroes on the display and opens the submenu.
The LCD has two visible text lines and the UP and DOWN control keys are used to scroll through the menu items. An arrow on the left side of the display highlights the current selection.
Move the arrow UP or DOWN to the desired selection and press ENTER to access the associated submenu (section
8
). To return to the preceding menu, press the ESC key.

and
Set Vgrid
are described below for use in installation. Complete descriptions of the submenus can be found in the full manual on the website.
Address:
In the
SETTINGS
menu, scroll to
Address
and press ENTER to open the submenu. Address values are
assigned manually using any value in the range 2 to 64. Press the UP and DOWN keys to scroll through numbers
and ENTER to select. Auto address = 1 and can be used only once; default address is set at 2.
Set Vgrid:
In the SETTINGS menu, scroll DOWN to Set Vgrid and press ENTER to open the submenu. To
choose a grid connection different from the 240V Split-phase default, use the UP or DOWN key to move the
arrow to the desired selection and press ENTER. A second display screen will open; press ENTER to confirm
selection or ESC to cancel.
Upon completion turn the DC Disconnect switch OFF to save changes.
The procedure for START-UP is as follows:
•
Set the inverter’s DC disconnect switch to ON.
•
Set the external AC disconnect switch to the inverter to ON.
Once both disconnects are closed, the inverter starts the grid connection sequence.
While the system checks for grid connection (Missing Grid) to be established, the ALARM LED turns steady YELLOW
and the POWER LED flashes GREEN.
When waiting for sunlight (Waiting Sun) the POWER LED turns steady GREEN. As soon as conditions are met, the
inverter is connected to the grid.
For –A versions ONLY
, the display shows the AFD board self-test running and results upon connection. If the self-test
results are OK, the inverter will continue to Next connections.
If a potential problem on the AFD board is detected, the self-test will result in error.
Refer to section
12
below to clear the error and restart the self-test.
All versions
will display the following screens during connection:
Time (seconds) remaining to complete the output voltage and
frequency values check, and whether the values are within
range.
A final display screen confirms RISO measurement.
If all items described above test OK, the inverter is connected to the grid and displays the message,
“Inverter OK”
,
along with the date and time. If there is not sufficient sunlight to connect to the grid, the unit will repeat the connection procedure
until all the parameters controlling connection to the grid (voltage and frequency, confirmation of no ground fault) are within
range. During this procedure, the green LED flashes ON and OFF.
Clock malfunctioning, or other non-function related faults that do not interfere with operation, may also be shown instead of the date and time.

AFD (arc fault detection)
An autotest circuit is included in the module design of the DC ARC FAULT CIRCUIT INTERRUPTER (AFCI) solution. The AFCI performs a self-test when the system is started, (ie
every morning when sunlight is sufficient for connection). The inverter display area shows the results of the self-test:
•
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.
Press and hold the ESC key for three seconds to clear the error and start the restart self-test. If self-test results are OK, the inverter will re-connect
to the AC grid. If the DC arc fault is still present, the self test will result in error E053.
Refer to the technical manual online for possible solutions.
•
During normal operation the input current is continually measured and analyzed.
•
If a DC arc fault is detected, the inverter is disconnected from the AC grid and error E050 will be displayed.
Refer to the technical manual online for possible solutions.
The AF self-test can be manually started anytime using the following procedure:
1. Turn off the inverter (switching off both DC and AC switches) and,
2. Turn on both the DC and AC switches waiting for display communication of self-test result.

To adjust frequency and disconnect times to meet local utility requirements, modifications are made using the Aurora Manager-TL software. The software, with
instructions to download and install on a PC, can be found on the website
Prior to connecting to the grid, with the inverter’s DC disconnect switch set to ON
, a computer, with Aurora Manager-TL software installed, should
be connected to the inverter via an RS-485-USB adapter (not included). The USB driver files and instructions for installation can be found on the website.
PC-inverter connection cable required is standard USB 2.0 cable, terminals type A and B.
After frequency and disconnect time values have been adjusted, turn DC power OFF and ON to save new data. Changes to parameters must be
made to meet the requirements of the local utility. Entry of improper values could cause inverter to shut down.
