3. SELECTION OF INSTALLATION LOCATION
The installation location of the AURORA inverter must be chosen taking in account the followings:
•
Choose a location sheltered from direct sunlight or other sources of heat.
•
Choose a well ventilated place so as to allow good circulation of air around the unit; avoid places where
air cannot circulate freely around the unit.
•
Choose a place with sucient space around the unit to permit easy installation and removal of the
object from the mounting surfaces.
•
If more than one unit is installed, avoid placing one unit above the other so as to prevent overheating
of the unit installed above through the heat given o by the one below. Some examples of multiinverter installations are shown in the picture below.

ARRANGEMENTS OF UNITS MINIMUM CLEARANCES AROUND THE UNIT
4. WALL MOUNTING
The AURORA inverter should be mounted vertically, with a maximum inclination from the vertical of 5°. Any
larger inclination from the vertical could reduce the power conversion capability with a consequent reduction
in energy harvesting.
To correctly wall mount the inverter, follow the following procedure:
•
Drill Ø 10 mm holes to a depth of 75 mm in line with the support bracket’s xing holes (det. [A]).
•
Secure the inverter’s support bracket using the SX10 dowels and 6.3x70 screws provided. The inverter’s spring
hook (det. [B]) must be positioned at the top; the xing PEM M6 (det. [C]) must be positioned at the bottom.
•
Hook the inverter to the bracket spring (det. [B]) by the screw holes in the bracket on the back of the
inverter (det. [D]). Secure the lower part of the inverter to the PEM M6 on the bracket (det. [C]) using
the M6x10 screw, the D.18 washer and the slot in the inverter’s lower ange (det. [E]).
Note: In the PVI-8.0/10.0/12.5-TL-OUTD models the support bracket only permits the upper part of the inverter to be secured
through the procedure previously described; to secure the lower part of the inverter, in the absence of the PEM M6, you must
make additional holes in line with the slot in the inverter’s lower ange (det. [E]), and then use the SX10 dowels and 6.3x70
screws to secure the part to the wall.

5. ELECTRICAL CONNECTIONS AC, DC SIDE AND PE CONNECTION
Warning! The inverters to which this document relates to are WITHOUT ISOLATION TRANSFORMER
(transformer-less). This type involves the use of insulated photovoltaic panels (IEC61730 Class A Rating) and
the need to maintain the photovoltaic generator oating with respect to earth: no pole of the generator must
be connected to earth.
Warning! Aurora inverters should be earthed (PE) via the terminal with the protective earth label ,
using a cable with an appropriate cross-section of the conductor for the maximum ground fault current that
the generating system might experience. Any damage caused to an inverter which is not earthed via the
appropriate terminal is not covered by the warranty.
Warning! Unauthorized removal of necessary protections, improper installation or tampering with the unit
(for example, the creation of additional holes, changes not covered in the guide below), cause the risk of
serious personal injury and / or property and entails the immediate loss of warranty.
Warning! Aurora inverters cannot be powered by unlimited sources of current, e.g. batteries. Powering the
device with this type of energy source can cause irreparable damage to the unit, with consequent invalidity
of the warranty conditions.
Warning! Aurora inverters are supplied with an internal protection system able to detect any ground fault occurring
on the DC side of the equipment or inside the inverter. This protection system, designed to disconnect the inverter in
the event of an accidental indirect contact or a breach of the insulation, is not capable of protecting the inverter from
a dead short of one of the poles of the solar array when the equipment is connected to the AC grid (such an event could
damage the inverter and such damage is not covered by the warranty); further, this protection system is not capable of
protecting the AC line to which the inverter is connected, for which you are recommended to install an automatic circuit
breaker which will cut out in the event of a leakage on that line. The following table shows the characteristics of such a
device that would be required for the various inverter models. The ratings (nominal current) for the switches reported
in the table below are given as approximate values: the selection of the device to be used must be based on installation
choices, such as any possible deratings due to the operative temperature of the switch.

5.1. Selection of the AC grid connection cable
The AC grid connection cable must be selected based on the criteria below.
•
Cable type:
The choice of the type of cable for the connection to the AC grid depends on the type of inverter to be installed
(single-phase or three-phase) and on the protective earth (PE) wiring; this may be integrated in a single sheath
with the conduction line (phase or phases + neutral) or it can be on a separate wiring.
For the three-phase models the wiring choice also depends on the selected conguration type for the AC
grid connection (delta or star): in case of delta congurations (pure three-phase) the neutral conductor is not
required.
Inverter type / conguration Cable type
Single-phase inverter
Three-way cable (L+N+PE) or
Two-way cable (L+N) and PE cable
Three-phase inverter with delta
grid connection
Four-way cable (R+S+T+PE) or
Three-way cable (R+S+T) and PE cable
Three-phase inverter with star
grid connection
Five-way cable (R+S+T+N+PE) or
Four-way cable (R+S+T+N) and PE cable
•
Cross-section of the internal conductor:
The cross-section of the AC line conductor must be sized in order to prevent unwanted disconnections of
the inverter from the grid due to high impedance of the line that connects the inverter to the power supply
point; in fact, if the impedance is too high, it causes an increase in the AC voltage (seen by the inverter) that,
on reaching the limit set by the regulations of the country of installation, causes the inverter to switch o.
The following table reports the minimum and maximum cross-sections of the internal conductor of each
individual AC cable for each inverter model.

•
Insert the AC grid and PE connection cables into the inverter, passing them through the previously
mounted cable glands.
•
Strip back the AC grid and PE connection cables: 10 mm for PVI-3.0/3.6/4.2/8.0/10.0/12.5-TL-OUTD
models, 12-13 mm for PVI-5000/6000-TL-OUTD models.
•
Connect the protective earth (yellow-green) cable to the contact labelled with the symbol on the
terminal block (det. [H]).
•
Connect the neutral cable (normally blue) to the terminal labelled with the letter N.
Note: In the PVI-8.0/10.0/12.5-TL-OUTD models the connection of
neutral conductor (N) is optional and depends on the system
in which the inverter is installed. If the AC Grid to which the
inverter is connected includes single-phase devices or inverters
which could create an imbalance in the three-phase system, you
are recommended to use a star conguration (three-phase +N).
However, where the circuit only includes 3ph inverters you are
recommended to use a delta conguration (neutral not connected).
In this case, the “3ph MOD” switch must be set to the Δ symbol
(det. [I]).

5.3. DC side connections
•
Check the polarity of each couple of cables that must be connected to the inverter input: mark the
cable corresponding to the positive pole so as to be able to distinguish it from the one corresponding
to the negative pole. In the case of several strings, observe the correspondence between the negative
and positive of each string.
•
Check the open circuit voltage of each pair of cables which must be connected in input to the inverter:
the value must in no case exceed the maximum input voltage of the inverter.
Warning! Voltage values which exceed the permitted levels may irreparably damage the unit. Any
consequential damage to the inverter is not covered by the warranty.
Warning! The maximum allowed current for each input connector is 20 A; for models equipped with input
fuses (sux “-FS”) this limit is set by the fuse current rating. Higher values may cause damage to the internal
fuses or to the fuses equipped on the unit.
Warning! The exposure to sunlight of photovoltaic panels generates dangerous voltages to the ends of the
cables of the PV generator. Before connecting cables from the PV generator to the DC input of the inverter you
MUST disconnect any external DC line or make the dimming of solar panels.
•
Crimp the Multicontact/Weidmüller MC4/WM4 quick t connector counterparts to the string cables or
to the cables wired to the string disconnect switches (external), paying attention to the voltage polarity
and to the connector / terminal, following the procedure below:
MOUNTING PROCEDURE FOR MULTICONTACT QUICK FIT CONNECTORS
•
Strip back the cable to which the connector
will be applied (after verifying it complies
with the connector limitations).
•
Apply the terminal to the conductor using
the special tweezers.
•
Fit the cable with the terminal inside the
connector until it snaps, indicating that
the terminal is securely tted inside the
connector.
•
Firmly tighten the cable gland in order
to prevent humidity inltration in the
connector, which may lead to increased
ground leakage.
Warning! Tightening the cable gland
is of crucial importance. Humidity

6. CONFIGURATION OF INPUT CHANNEL OPERATING MODE
The two input channels can be congured in two modes: independent mode and parallel mode.
The selection of the conguration of the input channels depends on the photovoltaic generator features and
on the power and current limitations of the inverter, as well as design choices and installation needs. Refer to
the system design documentation for information on the selection of the conguration of the inverter input
channels.
Warning! For the two channels to be used in independent mode, it is a NECESSARY condition that the
photovoltaic generator connected to each input has a maximum current and power below the channel’s
current and power limit.
Warning! For the two channels to be used in parallel mode, it is RECOMMENDED that the photovoltaic
generator connected to the two inputs has strings with the same number of modules in series and that all the
modules have the same installation conditions (inclination / orientation).
Refer to the technical data table in Appendix E to nd out the current and power limits of each input channel
for the various inverter models.
Warning! If the string’s current or power is above the current or power limit of the input channel to which it is
connected, the two input channels MUST be congured in parallel. This condition also concerns the case where
the photovoltaic generator comprises only one string with power above the inverter’s single input channel
power limit.
Note:
The inverters are pre-set in the factory with INDEPENDENT input channels.
Warning! If the conditions shown above are not met, consult the photovoltaic system’s designer immediately.

7. SIGNALS TERMINAL BLOCKS
7.1. RS485 communication line connection
The RS485 communication port is the inverter’s communication port. AURORA uses a HALF-DUPLEX RS485
communication line made up of two transmission reception lines (+T/R and –T/R) and a reference communication
line (RTN): all three lines must be wired in a daisy-chain (“in-out”). It is advisable to use a twisted-pair screened
cable for the communication line: the screen must be earthed at only one point (typically near the monitoring
system) and continuity inside each element of the chain must be given to the screen. Refer to Appendix C.
The chain connection can be made without distinction by using the connector couples (one for in and one
for out – det. [Q]) or the terminal block (det. [R] or det. [S]). The connectors are identied by the printing
“RS485(A)” and “RS485(B)”: use of connector “A” as in and “B” as out is not compulsory (both connectors can be

The PVI-3.0/3.6/4.2/8.0/10.0/12.5-TL-OUTD models are equipped with a two-level terminal block allowing
one level to be used for line-in connection and the other for line-out connection. The terminal block is also
equipped with the LNK terminal for the PVI-3.0/3.6/4.2-TL-OUTD models and SCLD for the PVI-8.0/10.0/12.5TL-OUTD models allowing continuity to be given to the cable screen.
On the other hand the PVI-5000/6000-TL-OUTD models are equipped with a one-way terminal block (det. [R])
and therefore it is necessary to couple the line-in and line-out leads in the same clamp.
Note: Models PVI-3.0/3.6/4.2/5000/6000-TL-OUTD are equipped with a USB communication port, mounted on the right hand
side of the inverter. The USB communication port is a service port. This port exists for diagnostic use and the internal
controller’s rmware upgrade and is limited to service sta. Although drivers have been released (compatible with
Windows XP and Windows 7, for which no upgrades are envisaged) which permit this port to be also used for monitoring
(not recommended), the primary use remains strictly tied to debugging and updating the system. Power-One recommends
the use of the RS485 port for the continuous monitoring of system data.
With regard to the communication interface, the use of the dedicated Power-One PVI-RS485_RS232 or PVIUSB-RS485_232 type converter is strongly recommended in order to prevent compatibility problems that can
sometimes be encountered with the standard models on the market.

8. PRECOMMISSIONING CHECKS
Warning! Carrying out preliminary checks before commissioning the inverter is always recommended; this
way you avoid possible damage to the unit that could be caused by its faulty installation.
The main checks to be performed are summarised in the following chapters.
8.1. Electrical checks
•
PE connection check: check the inverter has an earth connection.
Warning! Aurora inverters should be earthed (PE) via the terminal with the protective earth label ,
using a cable with an appropriate cross-section of the conductor for the maximum ground fault current that
the generating system might experience. Any damage caused to an inverter which is not earthed via the
appropriate terminal is not covered by the warranty.
•
Check of the input voltage values: check that the inverter’s input voltage does not exceed the
permitted limits (ref. technical data table in Appendix E). Voltage values above the specications
can irreparably damage the unit. Any consequent failure of the inverter is to be considered
outside the warranty.
•
Check of the input voltage polarity: make sure the input voltage has the correct polarity. The polarity
inversion at the input may irreversibly damage the unit.
•
Checking of earth insulation of the photovoltaic generator: Using a correctly sized disconnect switch,
short the positive and negative poles of the photovoltaic generator, then measure the insulation
resistance (R
iso
) using a megohmmeter between the two short-circuited photovoltaic generator poles
and the protective earth (PE) terminal of the inverter.
Mega
Inverter
IG
+
_
Warning! If the measured insulation resistance (R
iso
) is lower than 1 MOhm, the inverter will not
connect to the grid as ground leakage is detected on the photovoltaic generator (refer to chapter 12
to address the problem).
•
Check of the grid voltage: check that the voltage of the grid to which the inverter will be connected
complies with the values shown in the technical data table in Appendix E.
Voltage values above the specications can irreparably damage the unit.

8.2. Mechanical checks
•
Make sure the cable glands are mounted properly. The cable glands must be adequately locked and
prevent any movement of the cable. Also make sure the cable glands are solidly xed to the inverter’s
chassis.
•
Make sure that the gasket on the front panel has been correctly mounted. The gasket must completely
cover the red line on the front of the inverter.
REFERENCE LINE CORRECT MOUNTING
INCORRECT MOUNTING
•
Fasten the inverter’s front panel by screwing the screws on the panel with the Torx T20 wrench
provided.
Warning! To ensure the inverter is waterproof, the front panel screws must be tightened to a torque wrench
setting of at least 1.5 Nm (13.2 in-lbs).

9. USER INTERFACE AND USE OF THE DISPLAY
Aurora inverters are equipped with an LCD display, four buttons for menu navigation and three LEDs
indicating the device status.
9.1. Status LEDs
Aurora inverters are equipped with three LEDs that indicate real-time device status and any faults or errors:
a green “POWER” LED, a yellow “ALARM” LED and a red “GFI” LED. All possible activation combinations of the
LEDs relative to the status of the device are listed below.
LED BEHAVIOUR

the night).
The input voltage and/or power are not sucient to switch on the
internal logic circuits of the inverter.
Green:
Yellow:
Red:
Inverter initialization (loading
of settings and wait for grid
check).
This is a transition state during verication of the operating conditions.
During this phase, the input power is sucient and the inverter checks
the conditions necessary for the connection to the grid (for example:
input voltage, insulation resistance R
iso
, etc.)
Green:

The machine is operating normally. During this phase, the inverter
automatically seeks and analyses the maximum power point (MPPT)
available from the photovoltaic generator.
Green:
Yellow:
Red:
Ground fault detected on DC
side.
The inverter signals the detection of a low insulation resistance (R
iso
)
level during the preliminary stage or of a ground leakage on the DC side
during operation in parallel with the grid. The inverter disconnects from
the grid, thus NOT supplying any power. The problem may be due to an
insulation fault in the PV modules or in the connections on the DC side.
Green:
Yellow:

not connected to the grid.
During the Autotest stage the tripping threshold for voltage and
frequency limits is measured.
Green:
Yellow:
Red:
Internal fan fault.
The inverter does not disconnect and stays operational, supplying
power to the grid: critical environmental conditions may however give
rise to over-temperature conditions with possible power limitations.
Green:
Yellow:
Red:
Grid disconnection
Indicates that the grid voltage for allowing the inverter to connect to
the grid is not present. The inverter shows the “Missing Grid” message
on the display.

10.2. Connection to the grid
•
After you have set the Nation value, the message “Inizializing...Please Wait” is displayed. Depending on the input
voltage value, the inverter will show various messages on the display and change the behaviour of the three LED:
INPUT VOLTAGE DISPLAY MESSAGE LED STATUS DESCRIPTION
Vin < Vstart Waiting sun
Green = FLASHING
Yellow = OFF
Red = OFF
The input voltage is not sucient to permit
connection to the grid.
Vin > Vstart Missing Grid
Green = FLASHING
Yellow = ON
Red = OFF
There is sucient input voltage to permit connection
to the grid: the inverter waits until there is grid
voltage to carry out the parallel.
Note: The inverter is powered ONLY by the voltage coming from the photovoltaic generator: presence of grid voltage alone IS NOT
SUFFICIENT to permit the inverter to start up.
Note: The inverter start-up voltage (Vstart) is the input voltage value though which the inverter connects to the grid. This value avoids
repeated connection and disconnection in periods of reduced radiation (typically in the morning). It is possible to modify the start-up
voltage within a set range via the display and the four keys (Ref. Par. 9.2 and the technical data table in Appendix E). You are
recommended to reduce the start-up voltage only when absolutely necessary, i.e. when the Congurator software indicates that the
parameter needs to be changed to avoid repeated connection and disconnection to the AC Grid which could impact the reliability of
the AC grid relays.
Note: The start-up voltage also sets the minimum voltage for the inverter to operate in MPPT. The inverter turns itself o because
of input undervoltage when the input voltage (for each channel) drops below 70% of the start-up voltage (for the channel).
•
With the inverter in “Missing Grid” status, close the AC switch downstream the inverter so as to apply the
grid voltage to the inverter: the inverter performs the grid voltage check, measures the photovoltaic
eld’s insulation resistance against earth and carries out other self-diagnosis checks. During the checks
before the parallel with the grid, the green LED keeps ashing, the others are o.
Note: During the grid voltage check and measurement of the insulation resistance, the values for the grid voltage and frequency
and the insulation resistance measured by the inverter are shown on the display. The inverter completes parallel with the
grid SOLELY if the grid parameters meet the ranges provided for by the regulations in force and if the insulation resistance is
greater than 1Mohm.
•
If the preliminary checks for parallel to the grid are successful, the inverter connects to the grid and
begins to export power to the grid. At this stage, the display shows the inverter’s parameters in cycles.
The green LED stays lit whereas the others are o.
•
Turning o the unit: follow the operations described for commissioning in reverse order. Opening
the switch downstream the inverter will light up the yellow LED and display message W003 and then
“Missing Grid”; opening the built-in disconnection switch or the external disconnection switches will
completely turn o the unit (LED o and display o).
Note: During the night, or more generally when the input voltage (DC) is insucient to turn on the internal auxiliary power
supply, the inverter will be completely o.

14.1. Replacing the input fuses
Warning! Using fuses with inappropriate specications may irreparably damage the unit. Any consequential
damage to the inverter is not covered by the warranty.
Warning! In case of damage of one or more input fuses, the inverter (not being able to monitor the status of
fuses) will continue to export energy to the grid without signaling any alarm.
The input fuses must be replaced when:
− One or more input fuses have been damaged.
− The fuses tted on the inverter are not appropriate for the employed photovoltaic system.
The following table shows the specications of the replacement fuse.
Mechanical dimensions 10x38mm
Nominal voltage 1000Vdc
Nominal current 20A max.
Standard IEC60269-6
If updating is required for compliance with the employed photovoltaic system, to determine the correct
rating (nominal current) of the input fuses two aspects have to be taken into account:
− The fuse nominal current (I
rated
) must NEVER exceed the “Maximum Series fuse rating” shown on
the photovoltaic panels.
I
rated <
Maximum Series Fuse Rating
− The fuse nominal current (I
rated
) must be determined based on the string current and on the sizing guidelines
provided by the manufacturer to avoid untimely tripping. As a general direction, based on the photovoltaic
modules’ short circuit current (Isc), it is possible to calculate the rating of the fuse with the following formula:
I
rated > (1.4 ≈ 1.5)*Isc
Fuses must thus be chosen among the standard commercially available ratings, selecting the value that is
closest to the obtained result.
To replace the input fuses on models equipped with such components (PVI-8.0/10.0/12.5-TL-OUTD-FS),
follow the procedure below:
•
Disconnect the AC line by opening the disconnect switch integrated in the inverter and any external
disconnect switches.
•
Disconnect the DC line by opening any external disconnect switches or obscure the photovoltaic
panels then disconnect the input quick t connectors.
•
Remove the inverter’s front panel by unscrewing the screws on the
panel with the Torx T20 wrench provided.

procedure:
PROCEDURE FOR THE REPLACEMENT OF INPUT FUSES MODELS EQUIPPED WITH FUSE HOLDER EXTRACTORS
•
Remove the fuse holder by pressing its handle.
•
Extract the fuse to be replaced from the fuse
