DISCONNECT SWITCHES
The inverter is equipped with both AC and DC disconnects (power OFF) to stop
power conversion within the inverter. Before accessing the interior of the cabinet,
these disconnects must be in the OFF position. Since these disconnects only stop
power conversion within the inverter, both the DC (photovoltaic array) and AC
(utility grid) circuits must be isolated in order to fully ensure the inverter is deenergized. Wait five minutes for the inverter to de-energize before working on the
inverter.

Product Overview
GENERAL DESCRIPTION
The Advanced Energy inverter is designed to act exclusively as a grid-tied inverter
for photovoltaic (PV) systems. The inverter converts direct current (DC) electricity
generated by the photovoltaic arrays into usable alternating current (AC) electricity.
This means the inverter must be tied to the utility grid and a photovoltaic system in
order to operate properly. Because the inverter is tied to a local utility source, if local
electrical load exceeds the power generated by the solar array, the grid automatically
supplies the additional electricity needed. Likewise, if the inverter produces more
power than is needed, it feeds the excess power back into the electrical grid.
Advanced Energy Inverter Models
This manual provides the information necessary to successfully install and operate
the applicable Advanced Energy inverter.
Within the AE product line some inverter models can be factory configured with
different three-phase outputs. For specific product characteristics, refer to the

omnibus mises à la terre fournies. Le panneau photovoltaïque est mis à la
terre au moyen du GFDI. La connexion des conducteurs positifs ou négatifs
du panneau photovoltaïque à la terre à tout autre point du système pourrait
déjouer le circuit de protection contre les défauts de terre.
CAUTION:
The inverter may be factory configured for either positive or negative ground.
It may NOT be field configured to a different grounding once it is shipped
from the factory. To identify if your inverter is configured for positive or
negative ground read the label next to the DC landing bus bar. Verify that the
grounding configuration matches your installation grounding plan. If you need
to reconfigure the ground, contact Advanced Energy for assistance. DO NOT
ground either DC lead at the time of installation. This will defeat the integral
GFDI circuit.
ATTENTION:
L’inverseur peut être configuré à l’usine pour une mise à la terre positive ou
négative. Il ne peut PAS être configuré sur le terrain à une mise à la terre
différente une fois qu’il a été expédié de l’usine. Pour savoir si votre

The PVP250kW/PVP260kW inverter cannot operate with this remote disable
open. If the remote disable feature is not used, the remote disable terminal
block jumpers must be left in place for the inverter to operate.
You are required to establish this external remote disable connection if an additional
power source exists at your installation site that could be damaged if the PV system
continues to run when the power source turns on. For example, if you have an on-site
generator that supplies power when an electrical outage occurs, you should make the
remote disable connection from the inverter to the on-site generator to ensure the PV
system shuts downs when the generator turns on.

• Initialize: The inverter enters this state after a power cycle. Variables and
devices are initialized and I/O ports set. When initialization is complete, the
inverter enters the sleep state.
• Disabled: The inverter enters this state when the front-panel switch is in the
OFF position or when a disable command is received over the Modbus
connection. If a fault condition occurs, the inverter switches to the fault state.
When the fault is cleared and the condition no longer exists, the inverter returns
to the disabled state. The inverter displays a message on the screen indicating
the inverter is disabled. When an enable command is received or the front-panel
switch is changed to the ON position, the inverter switches to the sleep state.
The inverter will also enter the disabled state when the remote disable input
feature is applied.
• Fault: The inverter enters this state when any fault condition occurs. The
inverter can enter this state from any other state except initialize. Unless the
fault is latching, the inverter clears the fault when the fault condition subsides.
The inverter displays the fault codes and messages indicating the current fault
conditions. If the fault is latching, the inverter switches to the latched fault state.
The inverter enters this state when a latching fault condition occurs. The
inverter displays fault codes and messages indicating the current fault
conditions. When the fault is cleared, the inverter switches to the sleep state.
Descriptions of the inverter faults are included in the Troubleshooting chapter.
570-1001792-05A
Operation
5‑3
Advanced Energy
• Sleep: In this state, the inverter is enabled but the DC voltage is below the
minimum operating window. When the PV input voltage rises above the
starting voltage, the inverter switches to the startup delay state.
• Startup Delay: In this state, the inverter delays a specified time and then enters
the DC precharge state. The delay depends on the conditions prior to the sleep
state and the time taken to reach this state from the previous shutdown. If a grid
interactive fault occurred on the previous shutdown, the inverter will remain in
this state for five minutes.
• DC Precharge: In this state, the inverter closes the DC precharge-contactor,
which limits inrush current into the DC bus capacitors. When the DC bus
voltage reaches the PV input voltage and is greater than the DC start voltage,
the inverter switches to the AC precharge state.
• AC Precharge: In this state, the inverter closes the main DC contactor and the
AC precharge-contactor, which limits inrush current into the transformer. Once
the transformer is magnetized, the main AC contactor is closed and the AC precharge contactor is opened. After a short delay the inverter switches to the idle
state.
• Idle: In this state, the inverter stops energy conversion and displays a message
indicating that the inverter is idle. The inverter switches to the power tracking
state when the DC voltage is above the DC start voltage. If a fault condition
occurs, the inverter switches to the fault state. If the DC voltage drops below the
minimum, the inverter switches to the sleep state.
• Power Track: In this state, the inverter operates in voltage control mode using
the maximum power point tracking (MPPT) function. If a fault occurs, the
inverter switches to the fault state.

DISPLAY SCREENS AND OPERATION
The digital display located on the front of the AE inverter includes both a scrolling
display screen and buttons for operating. The display provides the unit operator with
information about the current state of the inverter.
There are five sets of screens that may display depending on the state of the inverter.
The five sets are:
• Initialize: The initialize state is displayed on the screen when the inverter is first
turned on.
• Energy tracking: These are the normal power production states of idle, run, and
AC and DC precharge. Following the startup delay, the inverter goes to energy
tracking which starts with the DC and AC precharge and then goes to idle and
run.

GROUND FAULT INTERRUPT DEVICE
The inverter is equipped with a ground fault detector interrupter (GFDI). The purpose
of the GFDI is to detect a ground fault (unintended current flow from the solar panels
to earth ground) and in this event, disable the inverter.
The GFDI functions using a 5 A fuse to connect or bond the solar array negative (or
the solar array positive, if using a positively grounded panel array) to earth ground.
If the ground fault current exceeds 5 A between the grounded array terminal and the
earth ground, the fuse will open and disconnect the solar panels from their ground
reference, interrupting the ground fault. In this situation, the inverter will cease
operation and display a fault message.

To Respond to a Ground Fault
WARNING:
For the GFDI circuit to function as designed, the solar array safety ground
must not be connected to the PV array positive or negative leads. Bonding
the safety ground to the grounded leg of the array anywhere but through the
inverter will cause the GFDI circuit to be bypassed. This would defeat the
operation of the GFDI and potentially create an unsafe operating condition.
AVERTISSEMENT:
Pour que le circuit GFDI fonctionne normalement, la prise de terre de
sécurité du système PV ne doit pas être branché aux câbles positifs ou
négatifs des piles PV. Brancher la prise de terre de sécurité au pied des piles
ou à toute autre partie que l’onduleur causerait une mise hors circuit du
GFDI. Ceci ne empêcherait le fonctionnement normale du circuit GFDI et
créerait des conditions de fonctionnement potentiellement dangereuses.

NETWORKING AND PERFORMANCE
MONITORING
The inverter has an integrated data monitoring module located in the dedicated data
monitoring compartment. The data monitoring module enables access to the inverter
performance data using the following methods:
• Basic performance data can be accessed using a free web-based monitoring
service provided by AE.
• The data monitoring module can deliver data to a third party monitoring system
through a Modbus/TCP over an Ethernet network, or Modbus/RTU over an
RS-485 network.

Advanced Energy
The primary purpose of the communications interface PCB is to provide a means to
communicate with the inverter through either Modbus RTU or Modbus TCP/IP.
These connections can be used for third party monitoring or for web-based inverter
monitoring through AE's mypvpower.com (which uses a proprietary Ethernet
protocol).
The communications interface PCB provides the following:
• Remote disable capabilities, which allow the inverter to be disabled through
external methods such as an e-stop, generator interlock, or fire alarm panel
• Binary Modbus device addressing
• Additional Modbus slave port terminal block, which makes it easier to run an
RS-485 daisy-chain network
Inverters with the old Comm X PCB do not support the remote disable feature or
other features associated with the communications interface PCB. To determine
whether a specific inverter has the communications interface PCB, visually inspect
the communication board in the unit to see if the remote disable terminal block is
present, and the wire harness is connected to the inverter control wire harness
connectors located at the edge of the board.
DANGER:
Risk of electrical shock. High voltages are present in the inverter cabinet.
Both AC and DC disconnects must be in the OFF position when working on
the unit. Wait five minutes to discharge high voltage before opening the front
panels of the inverter.
DANGER:
Risque d’électrocution. L’intérieur de l’onduleur est soumis à des hautes
tensions. Les interrupteurs de courant alternatif et continu doivent être mis
HORS TENSION durant les travaux sur l’unité. Attendez cinq minutes afin de

If you have questions about the capabilities of a specific unit, contact AE Solar
Energy Technical Support.
Ethernet Network Connection
An Ethernet connection can be used to connect the unit to the internet, or to a local
Modbus/TCP network not connected to the internet. AE offers a free basic
monitoring service through the solarenergy.advanced-energy.com website. Internet
service must be set up at the installation site before the inverter can be accessed
online. The data monitoring module supports only hard-wired CAT5 solutions to the
inverter. The module does NOT support wireless configurations. To access the data
monitoring information, customers need to provide a broadband Ethernet connection
to the inverter, based on the following specifications:
6‑2
Data Monitoring and Controls
570-1001792-05A
Advanced Energy® PVP250kW and PVP260kW Inverters
• Provide a DHCP-enabled, or static IP based broadband internet connection that
is always ON. This can be cable internet, a DSL line, or equivalent.
• Provide a hard-wired, Ethernet connection between the communications
interface PCB in the inverter and the closest site LAN connection.
◦ If multiple inverters are commissioned to a single site, an Ethernet hub can be
located in an outdoor-rated enclosure to distribute the LAN to the inverters.
☞ Important
The data monitoring module does not support dial-up modem connectivity.
☞ Important
Some complex networks may require a system administrator to add the inverter
to the network, or to configure the unit to a static IP address.
All AE commercial inverters come standard with an Ethernet port that is intended to
be connected to the Internet or to a local area network for Modbus/TCP. The
commercial inverter operates as an Internet appliance. The inverter communicates
with the AE data center using https (port 443). Communications is one way – the
inverter only communicates externally to the AE data center. Typically the inverter
posts approximately 50 kB of data to the data center every 15 minutes. The inverter
may post data more frequently for a short period of time if there is an inverter fault.
Connecting the Ethernet Cable
PARTS OR TOOLS REQUIRED
You need the following parts and/or tools to make the Ethernet cable connection:
• Ethernet LAN cable (Category 5 or above)
• RJ45 modular connector plugs
• Appropriate conduit fitting
• Ethernet hub, switch or router to provide network connectivity
• Cable tester
TO MAKE THE INVERTER'S ETHERNET CONNECTION
Use the following steps to complete the connection of the Ethernet cable to the
inverter's communication interface PCB:
1. Route the Ethernet (CAT5) cable from the Internet-enabled router, at the gland
plate location on the upper right side of the inverter, using the proper conduit

Advanced Energy
Modbus/TCP is a CAT5 Ethernet network. Modbus/RTU uses a twisted pair shielded
conductor RS-485 network.
NETWORKING USING THE MODBUS OPTION
The following steps are required to set up a Modbus TCP network for your AE
inverter:
• Field installation : This step can be completed onsite by a PV installer or an
electrician that does not have working knowledge of a Modbus network
◦ Consult the facility IT administrator for network device installation support
and coordination
◦ Install the Modbus network communications cabling
• Modbus network configuration: This step can be done onsite or remotely and
should be completed by the Modbus network programmer
◦ Set the IP address assigned to the inverter and port 502 for Modbus TCP
◦ Configure the point maps for the slave devices
Modbus TCP Installation
Disconnect the power to the inverter before starting the installation.
TO INSTALL THE MODBUS TCP CABLE
DANGER:
Risk of electrical shock. High voltages are present in the inverter cabinet.
Both AC and DC disconnects must be in the OFF position when working on

NETWORKING USING THE MODBUS RS-485
OPTION
The following steps are required to set up a Modbus RS-485 network for the AE
inverter:
• Field installation : This step can be completed onsite by a PV installer or an
electrician that does not have working knowledge of a Modbus network
◦ Installing the Modbus network wiring
◦ Configuring end-of-line termination and network biasing
◦ Setting the Modbus address for each slave inverter
☞ Important
The contractor responsible for network programming will need to
provide the slave addresses prior to setting the Modbus address for each
slave inverter.
The final part of the RS-485 installation process is the Modbus network
configuration. These steps should be completed by the Modbus network programmer.
The last two steps are:
• Setting the device addresses so the Modbus master program will accept the
Modbus addresses assigned during the field installation
• Configuring point maps for slave devices
Network Layout
When multiple inverters or other Modbus slave devices are connected to a single
Modbus master device, the multiple devices need to be connected in one of the three
daisy chain layouts shown in the following figure.

When multiple devices are wired to the network, the network shield must be
terminated to earth ground at one point on the network, typically at the
beginning or the end. For device connections the shield must be rewired to
provide a continuous shield and isolated from ground.
Modbus Wiring for the Communications Interface PCB
The communications interface PCB includes two Modbus slave port terminal blocks.
The two Modbus slave port terminal blocks can be used in an in-and-out
configuration for daisy-chain networking. The two terminal blocks are electrically
bonded on the PCB. Therefore, it does not matter which one is used or the order in
which they are connected. The following illustration provides an example of how the
two terminal blocks can be used.

TO INSTALL THE MODBUS RS-485 CABLE
DANGER:
Risk of electrical shock. High voltages are present in the inverter cabinet.
Both AC and DC disconnects must be in the OFF position when working on
the unit. Wait five minutes to discharge high voltage before opening the front
panels of the inverter.
DANGER:
Risque d’électrocution. L’intérieur de l’onduleur est soumis à des hautes
tensions. Les interrupteurs de courant alternatif et continu doivent être mis
HORS TENSION durant les travaux sur l’unité. Attendez cinq minutes afin de
permettre la décharge du courant haute tension avant de démonter les
panneaux avant de l’onduleur.
1. Disconnect the power to the inverter before starting the installation.
2. Remove the data monitoring gland plate on the upper right side of the inverter.
The data monitoring gland plate is a flat piece of metal covering the side entry
port to the inverter’s data monitoring compartment.
3. Punch or drill a hole in the desired location to allow access for the cable.
4. Install a water-tight conduit hub connection.
5. Replace the gland plate.
6. Route a RS-485 cable from the master device on the Modbus network port in
the facility that has been approved by the network administrator through the
conduit hub.
7. Connect each Modbus cable to a slave port terminal block on the
communications interface PCB. Connect the plus (+) cables to plus (+)
connections and the minus (-) cables to minus (-) connections so they
correspond throughout the network.
The Modbus slave port terminal blocks can be unplugged for easy wiring
access.

8. Connect a ground reference line to the terminal labeled SHLD
The shield of a communications cable may be used for this reference as long as
the shield is connected to earth ground at one point only. AE recommends that
all AE inverters have connected grounds when possible.
☞ Important
Some Modbus devices do not have a shield or reference input. In these
cases the device most often uses the DC power supply (-) as the RS-485
reference. It may be necessary to place an RS-485 isolator on these
devices or power them from a common DC supply that has its DC (-)
referenced to earth ground at the same point where the network cable
shield is earthed.
Setting the Jumper Pins
By default, the termination pins have three jumpers in the disabled position when the
inverter is shipped. The location of the jumpers can determine the following settings
for an inverter:
• Terminate the network
• Determine the center inverter(s) on the network
• Turn on biasing

The performance of your Modbus network may require each end of the network to be
terminated using 120 Ω termination resistors. When the network is long, relative to
the RS-485 bit rate in use, bus terminations must be installed. The network length is
determined by the total backbone cable length and not necessarily the line-of-sight
between the two furthest apart devices.

TO TERMINATE THE INVERTER NETWORK
If bus termination is desired and the inverter is on the end of the Modbus network,
you need to set the termination.
1. Verify that the J7 jumper is in the lowe, NC position.
2. Move the jumper to the upper pair of J11 pins labeled Line.
3. Verify that the J10 jumper is in the lower NC position.

TO SET THE CENTER INVERTERS FOR THE NETWORK
Inverters in the center of the network need the termination jumpers set to the disabled
position.
1. Verify that the J7 jumper is in the lower NC position.
2. Verify that the J11 jumper is in the lower NC position.
3. Verify that the J10 jumper is in the lower NC position.

TO SET NETWORK BIASING
Biasing sets the voltage levels on the data lines of an inactive or idle network. At
least one device on the network must provide biasing. On shorter networks with
fewer installed devices, biasing may only be needed on the device furthest away from
the master. Longer networks that are terminated on both ends may require two
devices to have their biasing enabled.
To Set the Jumpers to Use the Inverter’s Built-in Biasing
1. Move the jumper to the upper pair of J7 pins labeled High.
2. Verify that the J11 jumper is in the lower NC position.
3. Move the jumper to the upper pair of J10 pins labeled Low.

TO TERMINATE THE NETWORK AND ENABLE BIASING
As an alternative, an end inverter on the network can require both termination and
biasing to be enabled. Set the following jumpers to configure the inverter for both
settings.
1. Move the jumper to the upper pair of J7 pins labeled High.
2. Move the jumper to the upper pair of J11 pins labeled Line
3. Move the jumper to the upper pair of J10 pins labeled Low.

Setting the Modbus Address
A Modbus network containing slave devices requires a unique address for each slave.
These unique addresses allow the master device to identify and communicate with
each slave. The Modbus network administrator must assign a unique Modbus address
to each AE inverter.

TO SET THE MODBUS ADDRESS
1. Remove the communications PCB from the card cage to access the address
switch.
2. Determine each slave address.
3. Set the address on each slave device.
The slave address for each inverter is set using a binary coded DIP switch.
☞ Important
0 is not an allowed address.
☞ Important
Some Modbus master devices do not allow addresses above the decimal
value of 126. AE recommends keeping the slave id number between 2
and 100.
Device Addressing Example
Each inverter must be set to a unique address specified by the site monitoring
contractor. The address is set using a binary code on the address DIP switch.
To set an inverter to an address of 25:
1. Find the desired address in the left hand column of the table below labeled
“Unit Address”.
2. Identify which switches, by switch number, must be set to the ON position.
For example, an address of 25 requires switch numbers 1, 8, and 16 to ON.
3. Once the switches are set in the ON position, the switch should look like the
figure below.

TROUBLESHOOTING LAN CONNECTIVITY
Most connectivity problems relate to wiring issues or corporate security settings
blocking the inverter from accessing the Internet.
Wiring problems are usually caused by the following:
• Result of a poor crimp
• Wire that exceeds 320 ft. as specified in the installation of the inverter
• Pinched wires somewhere between the inverter and the hub or router
Corporate network problems will require support from your corporate IT department
where the inverter is installed. The most common problem is the inverter has not
been provided with DHCP server access using port 443 or the static IP address has
not been set.

Troubleshooting Inverter Faults
If a fault has occurred the inverter will cease power production until the fault is
cleared. A fault may be a latching or non-latching fault.
• Non-latching: Automatically clears if the fault condition is resolved and the
inverter automatically restarts after completing its startup sequence.
• Latching: Requires manual intervention to restart the inverter.
If the inverter has faulted, the display screen will show the corresponding fault
information in a series of three or more screens. The display will then cycle back
through the three screens.
• First screen: Displays the fault category followed by the hexidecimal fault
code(s) value.
• Second screen: Displays a text description of the fault code(s).
• Third screen: Displays Solar Energy Technical Support contact information.
In the following example, a system fault, SYS returned a code, indicating too many
fault restarts occurred. The 0000 indicates no fault occurred in the other fault
groups.

AC UNDER VOLTAGE FAULT
To Identify an AC Under Voltage Fault
If the inverter displays an AC Under Voltage fault and all the voltages going
into the inverter are within the tolerances provided in the specifications, continue
with the following troubleshooting tips.
1. Check the main branch circuit breaker.
a. If the breaker is not tripped:
Check the small fuses located on the AC distribution PCB (there are nine in
three sets of three). If one or more of these fuses have opened, replace them
with like parts (600 VAC, 10 A or 20 A as required)
2. If any of the fuses are open, visually inspect the wiring. Look for the following:
a. Frayed wires or carbon marks indicating a short
b. Burned traces on the PCBs
If any of these conditions are present, DO NOT START THE INVERTER.
Contact AE Solar Energy Technical Support for replacement parts or service.
IDENTIFYING A GROUND FAULT
The inverter is equipped with a Ground Fault Detector Interrupter (GFDI). The
purpose of the GFDI is to detect a ground fault (unintended current flow from the
solar panels to earth ground) and in this event, disable the inverter.
WARNING:
For the GFDI circuit to function as designed, the solar array safety ground
must not be connected to the PV array positive or negative leads. Bonding
the safety ground to the grounded leg of the array anywhere but through the
inverter will cause the GFDI circuit to be bypassed. This would defeat the
operation of the GFDI and potentially create an unsafe operating condition.
570-1001792-05A
Troubleshooting and Solar Energy Technical Support
8‑5
Advanced Energy
AVERTISSEMENT:
Pour que le circuit GFDI fonctionne normalement, la prise de terre de
sécurité du système PV ne doit pas être branché aux câbles positifs ou
négatifs des piles PV. Brancher la prise de terre de sécurité au pied des piles
ou à toute autre partie que l’onduleur causerait une mise hors circuit du
GFDI. Ceci ne empêcherait le fonctionnement normale du circuit GFDI et
créerait des conditions de fonctionnement potentiellement dangereuses.
The GFDI functions using a 5 A fuse to connect or bond the solar array negative (or
the solar array positive, if using a positively grounded panel array) to earth ground
on the DC distribution PCB.If the ground fault current exceeds 5 A between the
grounded array terminal and the earth ground, the GFDI fuse will open and
disconnect the solar panels from their ground reference, interrupting the ground fault.
In this situation, the inverter will cease operation and show a ground fault message
on the inverter display.
To Identify the Cause of a Ground Fault
1. Turn the ON/OFF switch on the display to the OFF position.
2. Turn the AC disconnect to the power OFF position.
3. Turn the DC disconnect to the power OFF position.
4. Identify the cause of the ground fault by checking the following items:
a. A configuration error during commissioning.
b. Switching the grounded conductor in the DC disconnect.
▪ For a negatively grounded system, the positive leg should be broken in the
DC disconnect.
▪ For a positively grounded system, the negative leg should be broken in the
DC disconnect.
c. A pinched wire in the installation connecting some part of the array or DC
wiring to earth ground.
d. Mismatched array strings in a multiple inverter installation.
e. An open GFDI fuse.
TO RESOLVE A GROUND FAULT
DANGER:
This unit contains energy storage devices that take up to 5 minutes to
discharge. Verify the high energy capacitors are completely discharged
before working on this unit.

DANGER:
Verify that no shock hazard exists between both fuse terminals and earth
ground before removing the fuse. A 600 V rated fuse pulling device is
required.
DANGER:
Vérifier qu’il n’y a aucun risque d’électrocution entre les deux bornes de
fusible et la prise de terre avant de retirer le fusible. Un arrache-fusible d’une
capacité de 600 V est requis.
1. Open the DC side door and locate the DC distribution PCB.
2. Inspect the 5 A GFDI fuse for continuity using a multimeter.
3. Remove the GFDI fuse.
4. Check for continuity (ohms) across the GFDI fuse.
If the meter indicates no continuity then a ground fault likely exists.
◦ Check the DC voltage between the grounded terminal of the array and earth
ground. The voltage should be less than 30 volts with the GFDI fuse
removed. If the voltage is higher than 30 volts, a ground fault likely still
exists. Check the array wiring. For the best results, perform this test with the
DC disconnect in both the ON and OFF positions.
◦ Make sure the grounded leg of the solar array is not disconnected in the DC
disconnect.
5. Once the ground fault condition has been eliminated, verify the voltage
between earth ground and the grounded side of the PV array is less than 30
volts.
6. Ensure the DC disconnect is in the OFF position and install the new GFDI fuse.
7. Restart the inverter.
If the ground fault cannot be eliminated, contact AE Solar Energy Technical Support.
