Electrical safety rules for electricians
•
Comply with all relevant electrical safety regulations of the installation country or
region.
•
Notice that the inverter is connected to two high voltage power sources:
- the solar arrays at the DC connectors
- the public electrical grid at the AC connector
•
Never perform solar array or inverter installation or cabling work while the inverter
is connected to the electrical grid or to the solar arrays.
•
Never work on control cabling while the inverter or external control circuits are
connected to power sources. Dangerous voltages (115 or 230 V) can exist on
external control circuits connected to the relay output terminals even when the
inverter is isolated from the solar arrays and electrical grid.
•
Never perform insulation resistance tests or voltage withstand tests on the
inverter.
•
Never open the secondary cover of the inverter. Dangerous voltages may be
present inside.
•
Isolate the inverter from all power sources before working on it.
14 Safety
Isolating the inverter from external power sources
Isolating the inverter from external power sources
1
Turn off the main disconnector and circuit breaker(s) at the AC distribution board.
2
Turn the DC switch on the front of the inverter to the OFF position. The DC switch does
not completely isolate the DC input connectors from the solar array.
3
If applicable, turn off disconnecting switches and circuit breakers between the inverter
and solar array(s).
4
Disconnect the DC cables from the inverter to ensure complete isolation from the solar
array(s).
5
Disconnect the AC cable from the inverter to ensure complete isolation from the electrical
grid.
Note: Although the inverter’s automatic disconnection switches isolate the inverter
electronics and solar array(s) from the electrical grid, they do not completely isolate the
inverter from the electrical grid. High AC voltage can still be present inside the inverter
and at the AC cable terminations.
6
Disconnect any external power sources connected to the control connectors (for
example, to the relay output).
7
Use a multimeter (impedance >1 MΩ) to check that there is no voltage between ground
and the inverter input and output terminals.
Notes:
WARNING! Do not use excessive force to remove or replace the front or
bottom covers. The DC switch must be turned OFF before the covers can be
removed. Covers must be replaced before the DC switch can be turned ON.
•
The DC connection terminals (DC+ and DC-) carry dangerous voltages (up to
900 V). Even in dim conditions, the solar array supplies voltage to the inverter.
•
Do not disconnect DC connectors while they are under load. Protect disconnected
DC connectors from the ingress of water and dirt by using DC connector sealing
caps.
•
The DC power switch on the front panel only turns the inverter on and off. It does
not completely isolate the inverter from the solar arrays or the electrical grid.
•
Dangerous voltages can be present at the terminals of the AC and DC cables
when they are not connected to the inverter. Handle disconnected cables
carefully.
 Grounding safety (PE)
WARNING! Ignoring the following instructions can cause injury or death,
increased electromagnetic interference and equipment malfunction.
Safety 15
Grounding safety rules for electricians
•
Comply with all relevant electrical safety regulations of the installation country or
region.
•
Always connect protective earth (PE) to the inverter and associated equipment to
ensure personal safety and electromagnetic compatibility.
•
Ensure that grounding connections are sized to meet safety regulations.
•
Chaining is not allowed. In multi-inverter installations, connect each inverter to the
protective earth (PE) of the distribution board separately.
•
Never ground the DC+ or DC- live conductors.
Notes:
•
PVS300 is a transformerless inverter; the DC side and AC grid are not
galvanically separated. Therefore the inverter must not be used with solar
modules which require DC+ or DC- conductor grounding.
•
The inverter has two protective earth terminals which are:
- a screw terminal connection inside the AC connector
- a PE screw for a cable lug connection to the right side of the AC connector.
•
As the touch current of the inverter may be higher than 3.5 mA AC or 10 mA DC in
case of failure of the protective earthing conductor, a fixed protective earth
connection is required. See Selecting the power cables on page 37.
 General safety
WARNING! Ignoring the following instructions can cause injury or death, or
damage to the equipment.
•
The inverter is not field repairable. Never attempt to repair a malfunctioning unit;
contact your supplier, local ABB representative or Authorized Service Center for a
replacement.
•
Protect the inverter so that dust from drilling cannot enter it during installation.
Electrically conductive dust inside the unit may cause damage or malfunction.
•
The inverter is heavy and should be lifted by two persons wearing appropriate
personal protective equipment.
•
Choose an installation location where audible noise from the inverter(s) is least
likely to disturb people.
•
Do not obstruct the inverter cooling air inlets and outlets. The mounting plate is
designed to maintain a small gap between the inverter body and the wall.
Safe start-up and operation
These warnings are intended for everyone involved in planning the operation, start up
or operation of the inverter.

Operation basics and
hardware description
What this chapter contains
This chapter briefly describes the construction, operation and control principle of the
PVS300 string inverter.
Overview
The PVS300 transformerless string inverter converts direct current (DC) generated
by the solar arrays to single phase alternating current (AC). The AC is then fed to
either the public electricity grid or to a load circuit which is connected to the public
electricity grid.
PVS300 is suitable for small and medium-size photovoltaic (PV) systems.
PVS300 is designed for installation in air-cooled outdoor rated enclosures. Installation
is performed with the help of a mounting plate. The DC and AC cable connections at
the inverter are made with quick connectors.
Two variable speed fans operate on a demand basis. A stirring fan prevents the
formation of heat pockets around the control board. A cooling fan provides air flow to
the heat sink and power electronics circuit boards. The fresh air intake for the cooling
fan is located in the cabling section of the inverter. A narrow gap between the inverter
and the mounting plate works as an air vent.
PVS300 provides comprehensive functions for system protection, system supervision
and external communication.
After the inverter has been installed and commissioned, it operates automatically
according to the following principle:
24 Operation basics and hardware description
1. As the sun rises, the inverter wakes up when there is enough daylight for the solar
modules to generate DC voltage in excess of the minimum inverter operating limit.
2. After waking up, the inverter verifies the status of the power line and then
switches to the normal operating mode.
3. During operation, the inverter feeds current to the power line, and monitors both
the solar arrays (DC) and power line (AC).
4. As the sun sets, the inverter enters sleep mode when there is insufficient daylight
to generate DC voltage in excess of the minimum inverter operating limit. The
inverter uses the AC power supply to keep the control unit working when the DC
voltage is too low (night time).

Features
 Operation and protection features
Feature
Description/Operation
Automatic operation
The inverter wakes up and goes to sleep automatically depending
on the solar radiation conditions. It connects and disconnects to
the electrical grid automatically according to country
requirements. The inverter studies the system operations; it
generates messages and production data information to the user.
DC string fuses,
monitored
String fuses provide protection for solar modules and string
cabling against earth faults originating from solar side installation
errors or faulty components.
DC surge protection
device, monitored
A surge protection device (SPD) protects the inverter from
induced voltage spikes, for example caused by thunderstorms
close to the installation location. The inverter monitors SPD
cartridges and informs the user when the cartridge must be
replaced.
DC switch
The manually-operated DC power switch which can disconnect
the inverter from solar modules under full load conditions. When
turned on, the DC switch interlocks the inverter’s bottom cover
and front cover so that they cannot be removed.
DC reverse polarity,
monitored
The inverter has a short circuit diode between the DC terminals to
protect the internal electronics from reverse voltages. In case of
reversed –dc and +dc connection the full short circuit current will
flow through the diode, setting the DC voltage to zero. The
inverter informs the user about reversed DC connection.
DC ground fault
monitoring
In accordance with VDE0126-1-1; the inverter monitors the
impedance between ground and DC terminals before grid
connection can be established.
MPPT
Maximum power point tracking. Inverter software function that
automatically operates the solar generator, array, string or module
at its maximum power point. PVS300-TL inverters have one
MPPT.
Residual current detection In accordance with VDE0126-1-1; the inverter has a DC and AC
sensitive residual current monitoring unit (RCMU) which
measures and sums the currents of L and N conductors. If
residual currents (DC or AC) are detected, the inverter
disconnects from the grid.
AC Grid monitoring with
anti-islanding
In accordance with VDE0126-1-1; the inverter monitors the
voltage and frequency of the electrical grid and can detect if the
grid is operating with tolerances. The inverter also stops power
conversion and disconnects from grid when missing electrical grid
is detected (anti-islanding).
AC Over current trip,
monitored
The inverter hardware has an over current trip function. The
inverter informs the user if over current trip is performed.
30 Operation basics and hardware description
Feature
Description/Operation
AC Short circuit protection In case of external AC side short circuit, the inverter trips to
protect its electronics.
Over temperature
protection
If the inverter detects potentially harmful internal temperatures, it
shall temporarily limit output power by changing the DC operating
point. If the internal temperature rises towards dangerous limits,
power conversion and grid connection is interrupted.
 User interface and communication features
Feature
Description/Operation
Control unit
The inverter has a detachable control unit which can be installed
remotely, either with a wired connection or a wireless link. The
control unit has a graphical display and straightforward keypad
with dedicated help key. The software functions are intuitive
including comprehensive system monitoring, setup assistance
and help menus for the user. The control unit can be operated 24
hours per day.
Inverter to inverter
communication link (I2I
link)
A (hard wired) serial communication link between three PVS300
inverters, each feeding into separate phases. The I2I link enables
inverters to share monitored information and is the basis for the 3phase monitoring function.
Three phase configuration With help of I2I link, three PVS300 inverters can be connected to
and monitoring
three separate phases to form a photovoltaic (PV) system which
has three phase AC grid connection and monitoring. In this
configuration the power output difference between phases can be
limited to a specific kVA value.
Status LEDs
The inverter has green and red LEDs which show the operational
status in addition to information provided by display. The control
unit has one green/red LED. If the control unit is remotely installed
the LEDs mounted on the inverter control board are visible for the
user.
Relay output
The inverter has an electrically isolated relay output. The inverter
software includes pre-programmed functions from which the user
can select the most suitable for the system. The relay output can
indicate the inverter’s grid connection or fault status, or it can be
used to control building load circuits based on the inverter’s
current output level. The output signal can be externally
monitored or it can command external equipment.
Embedded fieldbus
interface
A (hard wired) serial communication link supporting Modbus RTU
protocol. The EFB interface is used to establish communication
between the inverter and an external monitoring or control system
(for example, ABB remote monitoring adapter SREA-50).

What this chapter contains
This chapter instructs in planning the mechanical and electrical installation.
Selecting the location for the inverter
WARNING! Do not install the inverter in a location where:
•
corrosive, explosive or flammable materials are used or stored
•
there is a risk of mechanical impacts
•
there is a lot of dust, or any conductive dust
•
there is a risk of flooding or snow or sand piling
•
inverter will be near to a heat source. Exposure to external heat will reduce the
power output capacity and shorten the component lifetime.
•
The product is designed for indoor and outdoor installations which meet the
safety, ambient conditions and free space requirements. The installation site must
meet the specification in section Environmental data and requirements on page
115.
The supporting structure
and fastenings must be
strong enough to support
the weight of the inverter
unit(s) and must be made
of non-flammable material.
See section Mechanical
data on page 116.
The installation room or
cabinet must have
adequate ventilation,
airflow and cooling for all
equipment inside. See
Mechanical data on page
116. See Required
clearances for cooling on
page 123.
36 Planning the installation
The installation location
must be accessible in
emergencies and for
maintenance.
The installation location
must be out of reach of
children, pets and pests.
During operation, the
inverter can produce a
slight noise or vibration
which could disturb
people. Consider this
when selecting the
installation location and
materials.
When choosing the
installation place, ensure
that all labels on the
inverter are visible at all
times.
Do not install the inverter
in direct sunlight. Power
derating will occur if the
internal temperature of the
inverter gets too high.
Mount the inverter upright
on a vertical surface.
Protect from ice and snow.
Prevent exposure to dust
and harmful gases such
as ammonia.
Planning the installation 37
Selecting the power cables
 General rules
Dimension the DC input power and AC output power cables according to the local
regulations and the following rules:
•
Select cables rated for at least 70 °C maximum permissible temperature of
conductor in continuous use.
•
Select a DC cable rated for at least 1000 V DC and which is approved for solar
applications.
•
Use only double insulated cables at both DC and AC side.
•
Select an AC cable rated for at least 500 V AC.
•
The AC cable must have L, N and PE conductors.
•
Dimension the AC cables to carry the inverter load current with maximum voltage
drop of 1% between inverter and AC distribution board. See the following table.
•
The minimum PE conductor cross-sectional area is 10 mm2 for a copper (Cu)
conductor. If a cable with smaller PE conductor will be used, connect an additional
PE conductor of minimum cross-sectional area 6 mm2 with a cable lug to the
second PE terminal of the inverter.
•
When shielded cables are used, connect the cable shields to protective earth
(PE) in order to meet safety regulations.
The table below shows the maximum cable length depending on the size of the
phase conductor and the nominal output power.

Selecting the control cables
 General rules
It is recommended to use halogen free, shielded control and data cables.
A double-shielded cable is the best alternative for low-voltage digital signals but a
single-shielded twisted pair cable is also usable.
Double-shielded twisted pair cable
Single-shielded twisted pair cable
 Signals in separate cables
Never mix 24 V DC and 115/230 V AC signals in the same cable.
 Signals allowed to be run in the same cable
Relay-controlled signals can share the same cables as digital signals, provided that
their voltage does not exceed 48 V. It is recommended to run relay controlled signals
as twisted pairs.
Fieldbus and I2I link signals can share the same cable, provided that the Data +/signal conductors run in the same twisted pair and both interfaces have separate
functional ground conductors.
 Recommended relay cable type
Cable type with a braided metallic screen (for example, Lapp Kabel ÖLFLEX or
equivalent) has been tested and approved by ABB.
 Recommended cable type for Modbus over EIA/RS-485
Shielded twisted pair cable (STP), impedance 100...150 ohm with 120 ohm
termination resistors (for example, Lapp Kabel UNITRONIC® LiHCH (TP) or
equivalent) is recommended.
According to the RS-485 standard, 1200 m is the maximum cabling distance for data
transfer velocities under 100 kBits/s when termination resistors are used.
40 Planning the installation
 Recommended cable type for remote control unit and I2I interfaces
over EIA/RS-485
Shielded twisted pair (STP) cable (for example Lapp Kabel UNITRONIC® LiHCH (TP)
or equivalent) is recommended. These interfaces do not require termination resistors.
The cabling distance is related to the data transfer velocity. The default baud rate for
the remote control unit and I2I link is 19.2 kBit/s.
The approximate cable distance without termination, using twisted pair cable,
24 AWG or conductor diameter of 0.5 mm (0.2 mm2) is shown in the following table.

 Daisy-chaining of EIA/RS-485 transmission line
Daisy-chain networking topology is reliable and recommended in cases where
several PVS300 inverters are connected to Modbus or I2I over an EIA/RS485
transmission line.
When wiring a daisy-chain network to PVS300 terminals it is recommended to use
suitable crimped end-sleeves (diameter max. 2 mm) to join wires together for reliable
terminal connection.

42 Planning the installation
Checking solar array and inverter compatibility
Check that:
•
Solar modules and DC cables used in the system are Protection Class II certified
(double insulated).
•
Solar modules used in the system do not require grounding of DC+ or DCterminals.
•
Solar modules used in the system are all of the same type and that they all have
IEC 61730 Class A rating.
•
Solar strings to be connected to the inverter all have an equal configuration.
•
Solar string and array maximum short circuit currents and open circuit voltages
match the rated values of the inverter under local ambient conditions.
•
Solar array operating voltage range lies between the limits of the maximum power
point tracking (MPPT) voltage range.
•
The inverter’s standard 12A string fuse rating is adequate and compatible with the
solar array design and installation materials. Change the string fuses to a lower or
higher current rating if necessary to provide adequate system protection and
functionality. See section Warning messages on page 107.
 Process for selecting the string fuse nominal current rating IFN
•
Define the nominal short circuit current ISC rating from the data sheet of the
relevant solar module.
•
Define the maximum allowed series fuse rating or reverse current rating IR from
the data sheet of the relevant solar module.
•
Define the conductor current carrying capacity IC of the used string cable type
under the planned installation conditions. See section Selecting the power cables
on page 37.
•
Correct fuse current rating under planned installation conditions:
IFN > 1.56 × ISC
IFN ≤ IR or if IR not specified in module data sheet IFN < 2 × ISC
IFN ≤ IC
Implementing short-circuit and thermal overload protection
 Protecting the inverter and AC output cable from short-circuits
The inverter has an integrated automatic AC overcurrent trip function which limits
inverter damage if there is, for example, an AC side short-circuit or other overcurrent
event. Install an external circuit breaker at the distribution board to protect the AC
cable according to local regulations, appropriate AC line voltage and the rated current
of the inverter.
Planning the installation 43
 Protecting the solar array and DC input cables from short-circuits
The inverter DC string fuses and short-circuit diode protect the inverter DC circuit, the
DC input cables and solar modules from short-circuit situations provided that the DC
cables and solar array are dimensioned according to inverter nominal DC voltage,
current and string fuse ratings.
 Protecting the inverter and AC output cable from thermal overload
The inverter protects itself against thermal overload provided that the cable is
dimensioned according to the nominal current of the inverter. A circuit breaker should
be installed on the AC distribution board side to protect AC cabling and electrical grid
interface devices.
 The use of external RCD
The inverter has an integrated DC and AC sensitive RCMU to detect residual fault
and leakage currents. The inverter monitors residual currents during grid feeding. The
inverter will automatically disconnect from the grid if residual current is ≥300 mA or a
quick rise of ≥30 mA is detected.
During normal operation the inverters in a PV installation can generate capacitive
leakage currents typically <20 mA. Exact values cannot be given because the total
leakage current depends on the operating conditions and on the type of PV module
used in the system.
If an external RCD is required by local regulations, the use of an RCD type which has
a nominal rating of 100 mA per inverter connected to it is recommended.
Common grid type configurations
This section describes the common grid type configurations and highlights special
attention which is required when using them.
The grid is illustrated as voltage vectors representing the magnitude and phase
information for mains voltage from phases to other phases, neutral and earth. The
voltages (RMS) that are seen by the inverter between the L (Line) and N (Neutral) or
between the L and L terminals are shown in the following connection diagrams.
 Neutral grounded TN and TT type grids
In neutral grounded TN and TT type grids, the voltage seen by any PVS300 inverter
is the line-to-neutral voltage. The allowed line-to-neutral RMS voltages are 208, 220,
230 and 240 V. The following connection diagrams show three PVS300 solar
inverters connected to TN-S, TN-C, TN-C-S and TT grids.
Note: PVS300 must not be connected to line-to-line voltages in neutral grounded TN
or TT grids because this would damage the inverter and be dangerous.

 Corner grounded TN and TT type grids
Connection diagrams for three PVS300 solar inverters to corner grounded TN and TT
grids are shown in the following figures. In a corner grounded TN or TT type grid, the
voltage seen by a given PVS300 inverter is the line-to-line or line-to-earth voltage.
The allowed line-to-line RMS voltages are 208, 220, 230 and 240 V.
Note: In corner grounded TN or TT type grids, the PVS300 inverter may generate an
increased amount of leakage current to earth, potentially causing nuisance trips of
any external residual current device (RCD). The amount of leakage current depends
on the construction of PV installation, type of PV panels used and also weather
conditions. Therefore, an exact value for leakage current cannot be given or
calculated.
The inverter has an integrated DC and AC sensitive residual current monitoring unit
(RCMU) which can detect residual (fault, leakage) currents. During grid feeding
operation the inverter monitors residual currents. The inverter disconnects
46 Planning the installation
automatically from the grid if a residual current >300 mA or quick rise >30 mA is
detected.

Routing the cables
 General rules
Ideally, the input, output and control cables should be installed on separate trays.
If control cables must cross over power cables, arrange them at an angle as near to
90 degrees as possible. Try to ensure that control cables and power cables (AC and
DC) are kept at least 20 cm (8 inches) apart. Do not run any cables behind the
inverter.
Metal cable trays must be electrically bonded to each other and to the grounding
electrodes. Aluminium tray systems can be used to improve local equalizing of
potential.

when the DC input voltage is below a
threshold value and there is no control
unit activity during the threshold time
period. The power meter shows “-- kW”
when the inverter is going to sleep.
Stand-by
From sleep mode, the inverter switches
to stand-by mode if the DC voltage rises
above the threshold value or if there is
control unit activity (wake up call by the
user).
In stand-by mode, the inverter performs
continuous monitoring and the testing
required for safe grid connection.
The power meter shows “-- kW” when the
inverter is on stand-by.
Note: During stand-by operation the
inverter can draw power from the solar
array or the electrical grid.
Normal operation
The inverter has established a grid
connection. The solar array is producing
adequate electrical power which is being
fed to the grid. The rays of the sun

Operation 91
 Start up assistant
The Start up assistant appears automatically when the inverter is first installed. This
menu guides the user through the settings for language, date, time and installation
country.
Note: The installation country is permanent once the setting has been confirmed. If
you need to change the installation country, contact your ABB partner for advice.
If necessary, these parameters, except for installation country, can be adjusted later.
See Start-up on page 77 for the setting procedure.
 Output view menu
This menu shows the status and history of power produced by the system. In most
screens the user can toggle back and forth between numeric and graphical histogram
views to suit the user’s preference.
This is the “home” screen, from which the Menu is accessed. It is also normally the
view that appears when the inverter is powered on and it detects user interaction. The
Sun Display appears automatically when the control panel is not touched for a while
(default 3 minutes).
In multi-unit systems, it is possible to choose whether to show the combined output of
all units.
The histograms show one column per hour, day, month or year. The current column is
always shown in a different shade to the others.
Use the left and right arrow keys to choose between different time periods.
In the Output: Today view, the number in the upper right corner of the graphical
content area shows the cumulative value of energy produced during the day so far.
The number in the upper left shows the current output power in kW. If the inverter is
disconnected from the grid then “-- kW” is shown. If the inverter is connected to the
grid but is not feeding power, “0 kW” is shown.
The format (12 hour or 24 hour) of the time points below the graph initially depends
on the geographical location of the unit. The format is user selectable from the Date
and time menu.
In the Output: This week, Output: This month, Output: This year, and Output: 24
years views, the number in the upper right corner of the graphical content area
shows the cumulative value of energy that has been produced during the week,
month, year and 24 years respectively.
The Total page shows cumulative values since the unit was installed. The Energy
output and Operation time headers and values are always shown. The CO2 reduction
header and value are shown only if a reduction factor has been set with Menu -> CO2
reduction.
92 Operation
The Technical information page shows values that are only of interest to technically
oriented users.
The Sun display shows the current state of the unit and the output power in
graphical format. See The operating modes of the PVS300 string inverter on page 85
for examples. Use the up arrow to access the sun display.
When the unit is in power feeding mode, a full sun and ten rays are shown. The rays
are filled and empty in proportion to the current output power. For example, if half of
the rays are filled, the unit is operating at 50% output power.
 Menu
Menu is the main menu from which the user can change parameters and access
event logs. The different features are accessed through a hierarchical navigation
structure of submenus.
Used for displaying a list of settings or selections which can be scrolled.
Date & time submenu
Used to set the time and date as well as to choose the display format.
The user must select Daylight saving OFF/ON from the Date & time menu.
Language submenu
The Language menu shows the available and selectable control unit language
versions.
Note: The current version of the inverter firmware has English language support only.
CO2 reduction submenu
Use this menu to set the carbon dioxide (CO2) reduction factor.
The reduction factor is used to calculate how many tonnes of carbon dioxide
emissions would have been produced if conventional electrical energy sources were
used instead of solar power. The default value is 0.7 t/MWh. If the value is set to zero
then the CO2 reduction header is not shown in the Output view.
Traditional electrical energy sources produce carbon dioxide emissions. The level of
carbon dioxide emissions varies depending on the local electricity production mix.
Check the carbon dioxide emission data from your local electrical utility or carbon
monitoring institutes. Solar energy offsets production from traditional energy sources
and thereby reduces carbon dioxide emissions.
Screen submenu
Used to set the screen brightness, contrast and screensaver delay
Operation 93
By default, the display backlight is ON when the inverter is in operating mode. When
the inverter is in sleep mode, the control unit and display switch OFF completely. The
control unit wakes up and the backlight illuminates if the keypad is activated.
If the keypad is not used for a preset time when the inverter is in operating mode, the
Sun display shall appear automatically.
The user can set the reduced backlight function ON/OFF to dim the backlight when
the keypad is not used for a preset time period. The reduced backlight function is
mainly designed to be used when the Control unit is remotely mounted, for example
on a bookshelf in a residential house.
Events submenu
This is subdivided into two menus, one for faults and the other for events. In both
cases the view shows the date and nature of the fault or event. Push the Help (?)
button to see any available additional information about the event.
Events remain in the event log even after the faults have been solved. The inverter
automatically removes the oldest items from the event log when there is insufficient
memory to store new events.
Communication submenu
Contains the parameters that are needed to set up communication to other systems.
The purpose of the menu is to show a subset of the parameter groups which are used
to set up communications. Panel communication parameters shall be accessible in
this submenu. Other parameter groups are not accessible through this submenu.
If there are any assistants for communications settings, they shall be accessible
through the communications menu.
System info submenu
The System information submenu allows you to see the control panel version
information.
Self test submenu
The self test assistant is used to perform an automatic protection test of the inverter in
four stages (overfrequency, underfrequency, overvoltage and undervoltage). The
inverter temporarily disconnects from the grid during the test.
To perform the test the system should be completed and ready to start operation, and
the photovoltaic array should be exposed to adequate solar radiation. The duration of
the test varies, partly due to country-dependent regulatory delays for reconnection.
The test may take a few minutes to complete. It is not possible to exit the test once it
has started. The final screen of the assistant shows whether or not the inverter
passed the tests.
94 Operation
Note: The local regulations in Italy require that the self test is performed successfully
during commissioning. If the self test is unsuccessful in Italy, the inverter shall not
connect to the grid. For more guidance on the self test function, please see Further
information on page 129.
 Special screens
Special screens appear in situations where it is not applicable to show the device
status. These screens are characterized by the lack of a status bar and softkey bar.
The Special screens include:
•
The boot screen which appears when the control unit is connecting to the inverter.
•
The splash screen which appears while the user interface is loading.
•
The connection failure screen which indicates that the control unit and inverter are
not communicating properly.
 Messages

Maintenance
What this chapter contains
This chapter explains the routine maintenance actions for the inverter.
General about maintenance
The inverter is a high-quality product which is designed to require very little
maintenance and downtime. In the event of a problem or malfunction in the system,
the built-in monitoring diagnostics are designed to highlight the nature of the problem
or required maintenance action. With optional accessories, remote monitoring can be
implemented by using the embedded fieldbus interface and the SREA-50 Remote
monitoring adapter.
Only a limited number of parts can be replaced. Replacement fans can be delivered
quickly through your installation company or local ABB service. In the event of severe
damage, the whole inverter will usually need to be replaced. In case of severe
inverter damage or an unidentified fault, please contact your installation company or
local ABB service.
Self-diagnostics
The inverter self-diagnostic functions are active by default. They are designed to
warn the user of maintenance triggers, faults, etc. For example, they tell you when to
change the fans, fuses and surge protection varistors.
In the unlikely event that the self-diagnostic feature fails, the whole inverter will need
to be replaced.
96 Maintenance
Requirements for maintenance personnel
The maintenance person is typically the building or photovoltaic (PV) system
caretaker. For residential systems, the maintenance person is often the building
owner. During commissioning, the commissioning electrician must teach the
maintenance person the maintenance procedures and explain the easiest way to
order spare parts.
Maintenance procedures and intervals
The table below lists the routine maintenance intervals recommended by ABB.
The maintenance intervals are suggested for a typical inverter, in a typical location for
a typical operating duration. Maintenance intervals should be reduced if, for example,
the inverter is located in a relatively harsh environment (non-standard installations or
installations continuously operating under extreme environmental conditions).
Interval
Maintenance
action
Instruction
Weekly
Check event log Use the control panel to check the event logs from the
Events Menu. The menu shows the most recent events as
faults or other events. Note that a single fault can
potentially give rise to several events.
Events are stored in the memory until the event memory is
full. When the event memory is full the inverter
automatically removes the oldest events from the event
memory.
Monthly
Check
operation of the
cooling and
stirring fans
Check the Events menu for possible fan faults. The
inverter activates a maintenance reminder when both fans
(cooling and stirring) should be replaced.
Note that the cooling fan only operates when the inverter
detects that cooling is required.
Change the fan(s) when the inverter displays a fan fault or
a replacement reminder.
Monthly
Check the
environment
Make sure that the inverter is still in its intended operating
environment. Check that the installation environment is still
clean, dry, free of obstacles near to the inverter and that
the ambient temperature has not risen since installation.
Monthly
Cleaning
Clean the inverter installation space and mounting area
regularly to remove dust and dirt. This helps to prevent
clogging of the cooling fan and heat sink of the inverter.
Monthly
(Yearly if the
inverter is
indoors with
restricted
access)
Check
connections
Check that cables are properly routed to the inverter.
Cables should be tidy, secure and in good condition.
Check that connectors are properly connected and that
they are in a safe, unbroken condition. Check that possible
screw and spring terminal connections are tight.

Derating
The inverter monitors its internal temperature and derates the power output
accordingly to protect the inverter, protection devices and cabling. Derating is fully
automatic. While derating is active, if the inverter’s temperature still rises or the
operational currents are still too high, the inverter disconnects from the electrical grid
to protect itself. When the internal temperature falls, the inverter automatically
resumes power feeding.
The nominal output power can be achieved in ambient temperatures of up to 50 °C
(122 °F). In the ambient temperature range of 50…60 °C (122…140 °F), the output
power is derated.
