1 FOREWORD
This document contains a technical description of AURORA photovoltaic inverter so

as to provide the installer and user all the necessary information about installation,
operation and use of AURORA.
1.1 PHOTOVOLTAIC ENERGY
Industrialized countries (greater energy consumers) have been experimenting energy-
saving methods and reduced pollutant levels for many years thanks to the energy-
conversion process. This may be possible through a shrewd and rational consumption
of well-known resources, and also by looking for new forms of clean and not
exhaustible energy.
Regenerating sources of energy are fundamental to solve this problem. Under these
circumstances, solar energy exploitation to generate electrical (photovoltaic) energy is
becoming more and more important worldwide.
Photovoltaic energy, in any case, is of great advantage to the environment because the
radiated energy we receive from the sun is transformed directly into electrical energy
without any combustion process and without producing any pollution.
(PVI-5000/6000-OUTD-US Rev: 1.1)
2 SYSTEM DESCRIPTION
The AURORA inverter is capable of feeding a power grid using the power generated
by photovoltaic panels.
Photovoltaic panels transform the sun-radiated energy into electrical energy in the
form of direct (DC) current (through a photovoltaic field, also known as PV
generator). In order to utilize this energy and feed it back to the distribution grid, this
energy shall be turned into alternating (AC) current. Aurora does this conversion, also
known as DC to AC inversion, in a very efficient way, without using rotating parts but
just static power electronic devices.
When used in parallel with the grid, the alternate current generated by the inverter is
directly fed to the domestic distribution circuit, which is in its turn also connected to
the public power distribution grid.
The solar energy system can thus feed all the connected users, such as lighting
devices, household appliances, etc.
When the photovoltaic system is not generating sufficient energy, the power required
to ensure proper operation of connected users is taken from the public power grid.
While if the produced energy is too much, it is directly fed to the grid, thus becoming
available to other users.
According to national and local standards and regulations the produced energy can be
sold to the grid or credited to the user against future consumption, thus granting a great
saving of money.
2.1 Key elements of a photovoltaic system: “STRINGS” and “ARRAYS”
The so-called STRINGS technology has been developed in order to reduce the
installation costs of a photovoltaic system as much as possible. These costs are mainly
related to the wiring operations on inverter DC side and the consequent distribution on
the AC side.
A photovoltaic panel is composed of many photovoltaic cells assembled on the same
mount. A STRING is composed of a certain number of panels electrically connected in
series. An ARRAY is composed by one or more strings connected in parallel.
Larger photovoltaic systems may be implemented by using several arrays connected to
one or more AURORA inverters.
(PVI-5000/6000-OUTD-US Rev: 1.1)
The greater the number of panels in each string, the lower the cost and the less
complex the wiring connections of the system.

_ + PV Array
Fig.2 - Array Composition
WARNING: String voltage shall not exceed 600 Vdc for any reason, so as
to avoid damage to the equipment.
NOTE: A minimum input voltage of 200 Vdc is required for Aurora to start
the grid connection sequence. Once connected, Aurora will transfer the
maximum power available for any input DC voltage value in a 90V to
580Vdc range to the grid.
(PVI-5000/6000-OUTD-US Rev: 1.1)
The total current of an array must also be within the capability limits of the inverter.
For AURORA, the limit is set at 18 Adc maximum for each input. The AURORA
model rated 6000W/5000W is capable of handling 2 separate arrays. The maximum
current limit for each input is 18Adc.
If the output of photovoltaic system exceeds the capacity of a single inverter,
additional AURORA inverters can be added to the system; each inverter will be
connected to an adequate section of the photovoltaic filed on the DC side and to the
grid on the AC side.
Each Aurora inverter will work independent of the others and will push to the grid the
maximum power available from its own section of the photovoltaic panels.
There are several factors and considerations to be taken into account when designing a
photovoltaic systems, such as the type of panels, available room, location, long-term
target output, etc. The system configurator available on Power-One's web site at
www.power-one.com may help in sizing a photovoltaic system.

(PVI-5000/6000-OUTD-US Rev: 1.1)
2.2 Data Transmission and Check

When more than one inverter is used, remote monitoring can be implemented through
a sophisticated communication system based on an RS-485 serial interface, with a
USB port to facilitate access during installation. An optional Aurora Easy-Control
system is also available for remote monitoring via the Internet, analogue modem or
GSM digital modem.
2.3 AURORA Technical Description
Figure 4 shows a block diagram of AURORA. The main elements are the input DC-
DC converters (termed “boosters”) and the output inverter. Both the DC-DC
converters and the output inverter operate at high switching frequency to enable a
compact design and relatively low weight.
This is a transformer-less version of AURORA, i.e. without galvanic insulation
between input and output, which further increases conversion efficiency. On the other
hand, AURORA is equipped with the necessary protective devices to ensure safe
operation in compliance with applicable regulations without an insulation transformer,
as discussed in more detail in the relevant section.
Fig.4 - Aurora block diagram

(PVI-5000/6000-OUTD-US Rev: 1.1)
The block diagram shows an AURORA PVI-5000/6000-OUTD with two independent

input DC-DC converters; each converter is dedicated to a separate array with
independent Maximum Power Point Tracking (MPPT) control. This means that the
two arrays can be installed in different positions and orientations. Each array is
controlled by an MPPT control circuit.
Thanks to its high efficiency and generously sized heat sink, the AURORA inverter
provides maximum power operation in a broad range of ambient temperatures.
The inverter is controlled by two independent DSPs (Digital Signal Processors) and
one central microprocessor.
This way, grid connection is controlled by two independent computers in full
compliance with electrical power supply and safety regulations.
Aurora operative system communicates with the related parts to proceed to data
processing.
This process ensures optimal performance levels of the whole units, as well as a high
efficiency under all solar radiation and load conditions, always in full compliance with
the applicable directives, standards and regulations.
(PVI-5000/6000-OUTD-US Rev: 1.1)
2.4 Protective Devices
2.4.1 Anti-Islanding
When the local power distribution grid fails due to a fault or when the equipment is
shut down for maintenance operations, Aurora shall be physically disconnected under
safety conditions, so as to protect the people working on the grid, in full compliance
with the applicable prevailing national standards and regulations. To avoid any
possible islanding operation, Aurora is provided with an automatic disconnection
protective system called Anti-Islanding.
The AURORA PVI-5000/6000-OUTD-US model is equipped with a state-of-the-art
anti-islanding protection system certified to the following standards and regulations:
¾ CSA-C22.2 N.107.1-01 UL Std N.1741
2.4.2 Panel Ground Fault
This version of AURORA has been designed for use with panels with a floating
connection (positive and negative terminals not connected to ground). A sophisticated
ground protection circuit continually monitors the ground connection; when it detects
a ground fault, this circuit shuts down AURORA and turns on a red LED on the front
panel to indicate a ground fault condition. The AURORA inverter is equipped with a
terminal for the system grounding conductor; see section 3.6 (step 3) for more details.
NOTE: For more details of AURORA shutdown or possible causes of
malfunction, please refer to sections 5.3 and 5.4.
2.4.3 Further Protective Devices

Aurora is equipped with additional protections to guarantee safe operation under any
circumstances. The protections include:
¾ constant monitoring of grid voltage to ensure that voltage and frequency remain
within the specified operational limits (in accordance with UL 1741 standard);
¾ automatic power limitation control based on internal temperature monitoring to
avoid overheating (heat sink temperature ≤70°C [158°F]).
Many control devices are fitted to Aurora, making its structure redundant, but at
the same time ensuring a perfect and fully safe operation.
(PVI-5000/6000-OUTD-US Rev: 1.1)
3 INSTALLATION

this manual.
Inside AURARE there is a lithium battery type CR2032. When this battery is end of
life a message will be shown in the display informing that the battery need to be
replaced.
(PVI-5000/6000-OUTD-US Rev: 1.1)
The battery is visible after removing the AURORA frontal panel
To insert the new battery in the battery holder the component need to be slide in with a
30° angle as shown on fig 16. once pushed this way it will automatically found the
correct position inside the holder.
Fig.16 - Lithium battery replacement
WARNING: the replacement of this component shall be performed only by

trained personal.
Once the battery is replaced put back the front panel in the inverter and perform the
START UP procedure.
(PVI-5000/6000-OUTD-US Rev: 1.1)
4 START-UP
WARNING: Do not place any items on AURORA during operation.
WARNING: Do not touch the heat sink when the inverter is operating, as
some parts may be hot and cause burns.
The start-up procedure is as follows:
1) Set the external DC disconnect (for the photovoltaic panels) to ON
2) Set the external AC disconnect (for the grid) to ON.

There is no specific order for closing the two disconnects.
3) Once both disconnects are closed, the inverter starts the grid connection
sequence, unless the grid voltage and frequency parameters are found to be
outside the operating range as per UL 1741 standard. The check routine is
indicated by the green LED labelled POWER over the display flashing.
The check routine may take 30 seconds up to several minutes, depending on grid
condition. Three screens are shown on the display during the check routing:
• “Measuring Riso…”, connection in progress with progress indication.
• Grid voltage value and status compared to specified values
(within/outside range).
• Grid frequency value and status compared to specified values
(within/outside range).
4) When the connection sequence is completed, AURORA starts operating; proper
operation is indicated by a warning sound and the green LED staying on. This
means that sun radiation is sufficient to feed the grid.
5) If the grid check routine gave a negative result, the unit will repeat the procedure
until all grid voltage and frequency parameters and grid configuration are found to
be in the specified range. During this process, the green LED will keep flashing.
(PVI-5000/6000-OUTD-US Rev: 1.1)
5 MONITORING AND DATA TRANSMISSION
5.1 User’s Interface Mode

WARNING: The RS-485 cable must provide at least 600V protection.
Normally, the AURORA inverter operates automatically and needs no

particular supervision. When solar radiation is not enough to generate power for the
grid (for instance, at night), AURORA disconnects automatically and goes into stand-
by mode.
The operating cycle is resumed automatically the moment solar radiation becomes
strong enough. This is indicated by the LEDs.
Aurora inverter can provide operational data in the following ways:
¾ LED indicators
¾ Operational data on the LCD display
¾ Data transmission on a dedicated serial RS-485 line. Data can be collected by a
PC or a data logger equipped with an RS-485 port. If an RS-485 line is used, it
may be convenient to use the AURORA RS-485/RS232 Serial Interface
Converter model number PVI-RS232485. An optional AURORA Easy Control
data logger is also available.
¾ Data transmission via USB cable. This type of connection is typically used when
monitoring a single inverter and for maintenance purposes. To connect the USB
cable, remove the waterproof plug at the bottom end of the inverter right wall
(Fig.17).

(PVI-5000/6000-OUTD-US Rev: 1.1)
Fig. 18 - Data Transmission Options

(PVI-5000/6000-OUTD-US Rev: 1.1)
5.2 Available Data

AURORA provides two types of data that can be collected using the suitable interface
software.
5.2.1 Real-time operational data
Real-time operational data can be transmitted on demand through the communication
lines and are not stored by the inverter. The free AURORA Communicator software
available on the installation CD may be used to transmit data to a PC (please check for
the latest updated version at www.power-one.com).
The following data is available:
¾ Grid voltage
¾ Grid current
¾ Grid frequency
¾ Power transferred to the grid
¾ Voltage of photovoltaic array 1
¾ Current of photovoltaic array 1
¾ Voltage of photovoltaic array 2
¾ Current of photovoltaic array 2
¾ Heat sink temperature)
¾ Serial Number Part Number
¾ Manufacturing week
¾ Firmware revision code
¾ Daily energy
¾ Leakage current of the system
¾ Total energy
¾ Partial energy
¾ Mean grid voltage
¾ Insulation resistance
¾ Leakage current to ground
¾ Date, time
(PVI-5000/6000-OUTD-US Rev: 1.1)
5.2.2 Internally logged data

Aurora stores internally the following data:
¾ Lifetime counter of grid connection time

¾ Lifetime counter of energy transferred to the grid
¾ Energy transferred to the grid every 10 seconds for the last 8640 periods of 10
seconds (which on average cover more than 2 days logged data)
¾ Partial counter of grid connection time (counter start time can be reset using the
AURORA Communicator software)
¾ Partial counter of energy (uses the same start time of the partial time counter)
¾ Last 100 fault conditions with error code and time stamp
¾ Last 100 changes to grid connection parameters with parameter code and new
value.
The first two types of data are displayed on the LCD and through the RS-485
interface, while all other data can be displayed only through RS-485 interface
(PVI-5000/6000-OUTD-US Rev: 1.1)
5.3 LED indicators

There are three LEDs at the side of the display: the first LED from the left (POWER)
indicates proper operation of the inverter, the LED in the middle (FAULT) indicates a
fault condition, whereas the LED on the right (GFI) indicates a ground fault.
1. The green “Power” LED indicates that AURORA is operating correctly.

This LED flashes upon start-up, during the grid check routine. If a correct grid
voltage is detected and solar radiation is strong enough to start up the unit, the LED
stays on steady. If not so, the LED keeps flashing until solar radiation becomes
strong enough to start up the inverter. In this condition, the display will read “
Waiting for sun….”
2. The yellow “FAULT” LED indicates that AURORA has detected a fault condition.
A fault description appears on the display.
3. The red “GFI” (ground fault) LED indicates that AURORA is detecting a ground
fault in the photovoltaic system (DC side). When this kind of fault is detected,
AURORA immediately disconnects from the grid and the corresponding fault
indication appears on the display. AURORA remains in this condition until the
operator presses the ESC key to re-start the grid connection sequence. If AURORA
does not reconnect to the grid, call service to have the system troubleshooted.

NOTE: Inverter status is indicated by the corresponding LED turning

steady on or flashing and by a display message that provides a description
of current operation or fault condition (see next sections).
G 1) Nighttime mode
Y AURORA disconnected during night time; this occurs when input power
R is too low to feed the inverter.
G 2) AURORA initialization and grid check

Y Initialization in progress: input power sufficient to feed the inverter;
R AURORA is verifying start-up conditions (for instance: input voltage
value, insulation resistance value, etc.) and grid check routine is
launched.
G 3) AURORA is feeding the grid
Y After completing a set of electronics and safety auto-test routines, the
R inverter starts the grid connection process.
As mentioned above, during this stage AURORA automatically tracks
and analyzes the maximum power point (MPPT) of the photovoltaic
field.
G 4) Ground insulation fault
Y AURORA indicates that insulation resistance was found to be too low.
R This may be due to an insulation fault in the connection between the
photovoltaic field inputs and the ground.
WARNING: Shock hazard! Do not attempt to correct this fault
yourself. The instructions below have to be followed very carefully. In
case you are not experienced or skilled enough to work safely on the
machine, contact a specialized technician.
What to do after an insulation defect has been found
When the red LED turns on, try to reset the fault indication by pressing
the multi-function ESC key at the side of the display. If AURORA
reconnects to the grid, the fault was due to a transient event (such as
condensation and moisture getting into the panels). If this trouble
occurs frequently, have the system inspected by a specialized
technician.
If AURORA does not reconnect to the grid, open both the DC and AC
disconnect switches to place AURORA into a safe condition and
contact an authorized service center to have the system repaired.
(PVI-5000/6000-OUTD-US Rev: 1.1)
G 5) Malfunction/Fault indication
Y Every time Aurora check system detects an operative malfunction or
R fault of the monitored system, the yellow LED comes on and a message
showing the type of problem found appears on the LCD.
G 6) RS-485 address setup indication
Y During installation, the yellow LED will keep flashing until the address
R is acknowledged. For further information about address entering, refer to
section 6.3.
G 7) Grid disconnection
Y If a grid failure event occurs while the system is regularly operating, the
R yellow LED turns on steady.
5.4 Messages and Error Codes

The system status is identified through message or error signals appearing on the LCD.
The tables below summarize the two types of signals that can be displayed.
MESSAGES identify current AURORA status; so they do not relate to faults and
nothing has to be done; messages disappears as soon as the system is back to normal
operating conditions. See W strings in the table below.
ALARMS identify a possible fault of the equipment or of the connected parts. Alarm
signals will disappear as soon as the causes are removed, except for ground insulation
faults in the photovoltaic panels, which have to be corrected by qualified personnel.
Usually, when an error signal appears, an action is needed. This action will be
managed as much as possible by Aurora or, in case this is not possible, Aurora will
supply all the necessary helping information to the person who will have to carry out
the maintenance operations to fix the fault on the equipment or system. See E strings
in the table below.

6 DATA CHECK AND COMMUNICATION
6.1 Connection through RS-485 serial port or RJ12 connectors
6.1.1 RS-485 serial port

RS-485 serial port uses a three-wire cable: two wires are for signals and the third one
is for ground connection. Cable is routed through the holes located at Inverter bottom
which are blanked with waterproof plugs (see Fig.23).
Supplied cable gland must be installed in the suitable hole.
1st PLUG
2nd PLUG
Fig.23 - Holes for cables necessary for RS-485 port connection or wiring for RJ12
connectors connection.
For easier installation, the inverter features two holes so that input and output cables
can be separated in case more units are connected in a daisy chain as described below.
After passing through cable gland, cables are connected inside of the unit to RS-485
terminal blocks that can be reached by removing the front door. Refer to par. 3.7 for
details on front cover correct removal and reassembly procedure.
¾ Signal wires must be connected to +T/R and –T/R terminals

¾ Ground wire must be connected to RTN terminal

6.1.2 RJ12 connectors

As an alternative to RS485 serial connection, be it as single units or as a daisy chain,
inverter connection can be performed by means of RJ12 connectors (see fig. 24).
Wiring is again routed through the holes located at Inverter bottom which are blanked
with waterproof plugs (see Fig.23). Input wiring passes through one hole and is to be
assembled to one of the RJ12 connectors; ti does not matter whether it is no. 1 or no. 2
since signals are the same considering that they are connected in parallel.
Output wiring goes out from the other RJ12 connector through the other hole and
reaches the next unit.

6.1.3 Daisy chain
RS-485 terminal block or RJ12 connectors can be used to connect a single AURORA
inverter or many AURORA inverters connected in a daisy chain. Maximum number of
inverters that can be connected in daisy chain is 248. Recommended maximum length of this
chain is 1200 metres.
In case many inverters are connected in a daisy chain, it is necessary to assign an address to
each unit. Refer to paragraph 5.5.6.1 for instructions on how to set addresses.
Moreover, the last inverter of the chain must have line termination contact active (S2 switch -
120Ω TERM set to ON). See fig. 24.
Any AURORA device is supplied with default address two (2) and with the S1 dip switch in
the OFF position.
In order to ensure optimum communication on RS485 line, Power-One recommends to
connect PVI-RS232485 adapter in-between the first unit of the daisy chain and the computer.
See fig. 25 for further details.
To this purpose other equivalent devices available on the market can also be used but Power-
One does not assure correct connection operation since equipment has never been tested with
these equivalent devices.
Please note that these commercial devices could require an external termination impedance,
which is not necessary for Aurora PVI-232485.
The following diagram shows you how to connect many multiple units in daisy chain
configuration.
(PVI-5000/6000-OUTD-US Rev: 1.1)
Fig. 25 - Daisy chain multiple connection
NOTE: When using RS-485 link there can be up to 248 inverters connected on
the same link. Choose any address between 2 and 248
NOTE: When using RS-485 link, in case one or more inverters are added
later to the system, please remember to switch back to the OFF position the
dip-switch of the former last inverter of the system.
(PVI-5000/6000-OUTD-US Rev: 1.1)
6.2 Serial connection with USB port

Serial connection through USB port allows connection of a single inverter to a
personal computer equipped with a USB 2.0 interface and dedicated software supplied
by Power-One. PC-inverter connection cable is a standard USB 2.0 cable, 5 metre
long, with terminals of the A and B type. Just remove the waterproof plug located on
Aurora side to make the connection (see fig. 26).

7 TROUBLESHOOTING
Aurora inverters comply with standards set for grid-tied operation, safety and
electromagnetic compatibility.
Before being delivered, the product has been successfully subjected to several tests to
check: operation, protective devices, performance and durability.
All these tests, together with the system ensuring Power-One quality, guarantee
Aurora optimal operation.
In case of any possible malfunction of the inverter, solve problems as follows:
9 Work under safe conditions, as stated in chapter 3.5 and following, check that
connections between Aurora, photovoltaic field and power distribution grid have
been made correctly.
9 Carefully observe which LED is blinking and read the signal appearing on the
display; then, following the instructions given in chapters 5.3, 5.4 and 5.5, try to
identify the type of fault found.
If the malfunction cannot be removed by following these instructions, contact the

service center or the installer (see following page).
(PVI-5000/6000-OUTD-US Rev: 1.1)
Before contacting the service center, keep the following information handy:

8 TECHNICAL FEATURES
8.1 Input Values
WARNING: the Photovoltaic field and system wiring must be configured in

such a way that the PV input voltage is less than the maximum upper limit
independently from the type, the number and the operating conditions of the
chosen photovoltaic panels.
As panel voltage also depends on working temperature, the number of panels
per string shall be chosen according to the min. ambient temperature
expected in that special area (see table A).
WARNING: Inverter is provided with a linear output power derating

depending on the input voltage, starting from 530 Vdc (100% output power)
to 580 Vdc (0% output power)
WARNING: The open circuit voltage of the photovoltaic panels is affected

by the ambient temperature (the open circuit voltage increases as the
temperature decreases) you have to make sure that the minimum temperature
estimated for the installation doesn’t cause the panels to exceed the
maximum upper limit of 600Vdc. As an example, the following table shows
for typical panels of 36, 48 and 72 cells the maximum voltage of each panel
as a function of the temperature (assuming a nominal open circuit voltage of
0.6Vdc per cell at 25°C and a temperature coefficient of -0.0023V/°C). The
table shows, therefore, the maximum number of panels that can be connected
in series as a function of the minimum temperature at which the system will
operate. Consult the panel manufacturer for the correct temperature
coefficient of Voc, before calculating the maximum voltage of the
photovoltaic array.

8.5 Power Derating

In order to ensure inverter operation under safe conditions both from the temperature
and electrical point of view, the unit automatically decreases power input in the
distribution grid.
Power derating can occur in two cases:
Power reduction due to environmental conditions

Power reduction and temperature at which it occurs depend on many operating
parameters other than ambient temperature, such as input voltage, grid voltage and
power available from the photovoltaic panels. AURORA can thus decrease power
output during certain periods of the day according to these parameters.
In any case, AURORA ensures top power up to 40°C ambient temperature, as far as it
is not directly exposed to the sun.
Power reduction due to input voltage

The graph shows automatic power output derating when input or output voltage is too
high or too low.
