voltage and DC voltage from solar modules.
- The connection area should only be opened by a licensed
electrician.
- The separate power stage set area should only be disconnected from the connection area after first being disconnected from the grid power.
- The separate power stage set area should only be opened
by Fronius-trained service personnel.
Never work with live wires! Prior to all connection work, make
sure that the AC and DC wires are not charged.
WARNING! Incorrect operation and work performed incorrectly
can cause serious injury & damage! Only qualified staff are
authorized to install your Fronius IG Plus and only within the
scope of the respective technical regulations. Do not start
operation or carry out maintenance work before you have read
the chapter ‘Safety Instructions’!
Protection of
persons and
equipment
The design and function of the Fronius IG Plus unit offers a maximum
level of safety, both during installation as well as in operation.
The Fronius IG Plus provides operator and equipment protection through:
a) galvanic isolation
b) monitoring the grid
Galvanic isolation
The Fronius IG Plus is equipped with a high frequency transformer that
ensures galvanic isolation between the DC side and the grid, thus ensuring the highest possible safety.
Monitoring the
grid
Whenever conditions in the electric grid are inconsistent with standard
conditions (for example grid switch-off, interruption, etc.), your Fronius IG
Plus unit will immediately stop operating and interrupt the supply of power
into the grid.
9
http://www.wholesalesolar.com/inverters.html
Monitoring the
grid
(continued)
Your Fronius IG Plus unit determines the grid’s status by:
- monitoring voltage
- monitoring frequency
- monitoring islanding conditions
Information
for Field adjustable trip
points
The Fronius IG Plus unit is provided with field adjustable trip points. For
further information please contact Fronius technical support E-Mail: pv-ussupport@fronius.com.
FCC Compliance
This device complies with Part 15 of the FCC Rules. Operation
is subject to the following conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including
interference that may cause undesired operation.
Ground Fault
Detector /
Interruptor
The Fronius IG Plus is equipped with a ground fault detection and interruption (GFDI) circuit as required by UL 1741 and the National Electrical
code.
Depending on the system configuration either the PV array’s negative or
positive conductor is connected to the grounding system in the inverter. If
a ground fault occurs in the DC wiring, the inverter disconnects from the
grid.
Standards and
Regulations
Your Fronius IG Plus unit complies with the requirements for the following
standards "Inverters, converters and controllers for use in independent
power systems":
- UL1741-2005
- IEEE 1547-2003
- IEEE 1547.1
- ANSI / IEEE C62.41
- C22.2 No. 107.1-01 (Sep. 2001)
The ground-fault detection and interruption is in compliance with NEC 690
building code requirements.

The Fronius IG Plus Unit in the PV System
General information
The solar inverter Fronius IG Plus is the highly complex link between solar
modules and the grid.
Fronius IG Plus
Main AC
Load
Center
PV array
Energymeter
Tasks
The main tasks of the Fronius IG Plus include:
- Converting DC into AC current
- Fully automatic operation management
- Display function and data communication
Converting DC
into AC current
The Fronius IG Plus unit transforms the direct current generated by the
solar modules into alternating current. This alternating current is fed into
your home system or into the public grid and synchronized with the voltage that is used there.
Important The Fronius IG Plus has been designed exclusively for use
in grid connected photovoltaic systems. It cannot generate electric power
independent from the grid.
Fully automatic operation
management
The Fronius IG Plus is fully automatic. Starting at sunrise, as soon as the
solar modules generate enough power, the automatic control unit starts
monitoring voltage and frequency. As soon as there is a sufficient level of
irradiance, your solar inverter starts feeding energy to the grid.
The control system of the Fronius IG Plus unit ensures that the maximum
possible power output is drawn from the solar modules at all times.
This function is called MPPT (Maximum Power Point Tracking).
11
http://www.wholesalesolar.com/inverters.html
Fully automatic operation
management
(continued)
As dusk starts and there is no longer sufficient energy available to feed
power into the grid, the Fronius IG Plus unit shuts down the grid connection completely and stops operating. All settings and data recorded are
saved.
Display function and data
communication
The display on the inverter is the interface between the inverter and the
operator. The design of the display is geared towards simple operation
and making system data available as long as the inverter operates.
The Fronius IG Plus is equipped with a basic logging function to monitor
minimum and maximum data on a daily and a cumulative basis. These
values are shown on the display.
There is also an option to allow the reading of the following weather data
on the display:
- two different temperature readings (for example, temperature at the
solar modules as well as the outside temperature)
- irradiance
A wide choice of data communication products allows for many possibilities of recording and viewing data.
System Upgrades
The Fronius IG Plus is designed for various system upgrades, e.g.:
- Upgrades that enable Fronius IG Plus to communicate with external
system upgrades as well as other inverters
- Datalogger and modem interface, Ethernet/Internet connection (for
using a PC to record and manage data from your photovoltaic system)
- Various large-format displays
- Living room display (Fronius Personal Display)
- Sensors (e.g. for temperature, irradiance, energy meter, wind speed)
- Interface cards
System upgrades are available as plug-in cards or external boxes.
Forced ventilation
The temperature controlled, variable speed fan with ball bearing support
of the Fronius IG Plus provides:
- optimal inverter cooling
- efficiency increases
- cooler components, thus improving service life
- least possible energy consumption and noise level
12
http://www.wholesalesolar.com/inverters.html
Power Derating
Should there be insufficient heat dissipation in spite of the fan operating at
maximum speed (for example inadequate heat transfer away from the
heat sinks) the power will be derated for protection of the Fronius IG Plus
unit.
Derating the power reduces the output of the Fronius IG Plus unit for a
short period sufficient to ensure that the temperature will not exceed the
admissible limit.
Your Fronius IG Plus unit will remain ready for operation as long as possible without any interruption.

Choosing the Location
Choosing the
location general
Please note the following criteria when choosing a location for the Fronius
IG Plus:
Only vertical installation
Max. ambient temperatures: -4 °F / +122 °F (-20 °C / +50 °C)
Keep a distance of 8 in. (20 cm) minimum between each inverter or
anything to the right or left of the inverters such as walls or DC and AC
disconnects.
For optimal airflow and cooling efficiency in hot climates Fronius recommend a distance of 10 - 12 in. (25 - 30 cm).
When installing more than one unit, keep a distance of 12 in. (30 cm)
between each Fronius IG Plus.
Keep a clearance of 3 ft. (66 cm) minimum below the unit, according to
NEC for code compliant disconnect location
The air flow direction within the inverter is from right to left (cold air intake
on right, hot air exit on left).
When installing the Fronius IG Plus unit in a switch panel cabinet (or
similar closed environment) it is necessary to make sure that the hot air
that develops will be discharged by forced ventilation.
The Fronius IG Plus is designed for installation both indoors and
outdoors.
Choosing a
Location for
Inside Installation
During certain operation phases the Fronius IG Plus unit may produce a
slight noise. For this reason it should not be installed in an occupied living
area.
Do not install the Fronius IG Plus in:
- areas with large amounts of dust
- areas with large amount of conducting dust particles (e.g. iron filings)
- areas with corrosive gases, acids or salts
- areas where there is an increased risk of accidents, e.g. from farm
animals (horses, cattle, sheep, pigs, etc.)
- Stables or adjoining areas
- Storage areas for hay, straw, chaff, animal feed, fertilizers, etc.
- Storage or processing areas for fruit, vegetables or winegrowing products
- Rooms used in the preparation of grain, green fodder or animal feeds
- Greenhouses
23
http://www.wholesalesolar.com/inverters.html
Choosing a
Location for
Outside Installation
NEMA 3R protection means that the Fronius IG Plus can be exposed to
moisture. However, we recommend that direct moisture and direct water
spray such as a sprinkler be avoided, if possible.
In order to protect the display, the Fronius IG Plus should not be exposed
to direct sunlight. Ideally, the Fronius IG Plus should be installed in a
protected location, e.g. near the solar modules or under a roof overhang.

Connecting Solar Module Strings to the Fronius
IG Plus (DC)
General Information About
Solar Modules
In order to select suitable solar modules and get the most efficient use out
of the Fronius IG Plus, please note the following points:
-
-
Safety
The open circuit voltage increases when temperature decreases
(assuming constant irradiance of 1000 W/m²). The inverter opencircuit voltage should never rise above 600 Volts.
Whenever the open-circuit voltage of the solar modules exceeds 600
Volts, the Fronius IG Plus unit may be damaged, and all warranty
rights will become null and void.
More exact data for sizing the solar array for the particular location
can be obtained using calculation tools such as the Fronius Configuration Tool (available on http://www.fronius-usa.com).
See NEC table 690.7 for the appropriate code-related voltage adjustment factor for crystalline silicon modules, or use the manufacturer’s
specified voltage coefficient.
WARNING! An electrical shock can be fatal. Danger from grid
voltage and DC voltage from solar modules.
- The connection area should only be opened by a licensed
electrician.
- The separate power stage set area should only be disconnected from the connection area after first being disconnected from the grid power.
- The separate power stage set area should only be opened
by Fronius-trained service personnel.
Never work with live wires! Prior to all connection work, make
sure that the AC and DC wires are not charged.
The DC main switch is only used to switch off power to the
power stage set. When the DC main switch is turned off, the
connection area is still energized.

WARNING! An electric shock can be fatal. Normally grounded
conductors may be ungrounded and energized when a ground
fault is indicated. The ground fault has to be repaired before
operation is resumed.
NOTE Do not connect the ground to the DC negative at any
point! This is already done within the Fronius IG Plus. If the DC
negative is connected to ground at the DC terminal block or prior,
this will circumvent the GFDI protection system, preventing your
Fronius IG Plus from properly detecting a fault current. Additionally, turning the DC disconnect to the off/open-circuit condition will
not disconnect the array from ground, as it only disconnects the
DC positive.

Criteria for the Proper Selection of String Fuses
DC disconnect
requirements
NEC 690.15-18 allows the use of fuse holders as a suitable means of
disconnecting PV arrays for servicing. Additional DC disconnects external
to the inverter may be required by the local authority having jurisdiction.
General
The use of string fuses in the inverter also adds fuse protection to the
solar modules.
A crucial factor for the fuse protection of solar modules is the maximum
short circuit current (ISC) of the respective solar module.
Criteria for the
Proper Selection of String
Fuses
The following criteria must be fulfilled for each solar module string when
using fuse protection:
- IN > 1.56 x ISC
- IN < 2.00 x ISC
- VN >/= 600 V DC
- Fuse dimensions: Diameter 10.3 x 35 - 38 mm
IN ....... Nominal current rating of fuse
ISC ..... short circuit current for standard test conditions (STC) according to
solar module data sheet
VN ..... Nominal voltage rating of fuse
NOTE The string fuse size must not be greater than the maximum fuse size rating of the PV module as provided on the PV
module manufacturers data sheet. If no maximum fuse size is
indicated, please contact the PV module manufacturer.
Effects of
using underrated fuses
In underrated fuses, the nominal current value is less than the short circuit
current of the solar module.
Effect:
The fuse may trip in intensive irradiance conditions.
42
http://www.wholesalesolar.com/inverters.html
Fuse Recommendations Application
Example
NOTE
Only select fuses suitable for a voltage of 600 V DC.
Example:
Maximum short circuit current (ISC) of the solar module = 5.75 A
According to the criteria for selecting the correct fuse, the fuse must have
a nominal current greater than 1.5 times the short circuit current:
5.75 A x 1.56 = 8.97 A
The fuse that should be selected according to the ‘Fuses’ table: KLK D 9

Connecting combined Solar Module Strings
using a DC String Input Combiner
General
When more solar module strings are combined to one solar module string
prior to the inverter, the solar module string current may exceed the permissable DC input terminal current rating of 20 A.
In this case the DC cables can be connected to the Fronius IG Plus using
a string input combiner as an option.
Additional

Components
The following additional components are required for connecting combined solar module strings using a DC string input combiner:
-
2 string input combiners

Solar Net and
Data Interface
Fronius developed Solar Net to make these add-on system components
flexible and capable of being used in a wide variety of different
applications. Solar Net is a data network which enables several Fronius
IG Plus units to be linked with the system upgrades.
Solar Net is a bus system. A single wire is all that is required for one or
more Fronius IG Plus units to communicate with all system upgrade
components.
The core of the Solar Net is the Datalogger. It coordinates data
transmission and ensures quick and safe distribution and storage of large
volumes of data.
The ‘Fronius Com Card’ is required to integrate the Fronius IG Plus into
the Solar Net.
Important Every Fronius IG Plus that is to be monitored using a Datalogger requires a ‘Fronius Com Card.’ In this case, the ‘Fronius Com Card’
serves as a link between the internal network of the Fronius IG Plus and
the Solar Net interface of the Datalogger.
Important Each inverter can only have one ‘Fronius Com Card.’ A network may only contain one Datalogger.
The first Fronius IG Plus with a ‘Fronius Com Card’ can be up to 3280 ft
(1000 m) away from the last Fronius IG Plus with a ‘fronius Com Card’.
Different system upgrades are detected automatically by Solar Net.
In order to distinguish between several identical system upgrades, each
one must be assigned a unique number.
68
http://www.wholesalesolar.com/inverters.html
Solar Net and
Data Interface
(continued)
In order to uniquely define each Fronius IG Plus in Solar Net,
each Fronius IG Plus must also be assigned an individual number.
You can assign individual numbers as per ‘The Setup Menu’ section in
this manual.
More detailed information on the individual system upgrades can be found
in the relevant operating instructions or on the Internet at
http://www.fronius-usa.com.

Energy supplied
energy supplied during monitored
period (kWh / MWh)
Due to the variety of different monitoring systems, there can be deviations
between the readings of other metering instruments as compared to the
readings from the Fronius IG Plus. For determining the energy supplied to
the grid, only the readings of the calibrated meter supplied by the electric
utility company are relevant.
Yield
money earned during monitored
period (set currency and price per
kWh in setup menu)
As was the case for the energy supplied, readings may differ from those
of other instruments.
CO2 reduction
CO2 emissions avoided during monitored period (lb / T); T = tons
The area for unit display switches between ‘lb’ and ‘CO2’.
The CO2 meter gives an indication of CO2 emissions (in lb/t) that would be
released during the generation of the same amount of electricity in a
combustion power plant.
This is set for 1.3 lb/kWh in the factory.

Status Diagnosis and Troubleshooting
Displaying
Status Codes
Your Fronius IG Plus unit is equipped with a self diagnostic system that
automatically identifies a large number of possible operation issues by
itself and displays them on the screen. This enables you to know immediately if there are any malfunctions in the Fronius IG Plus, the photovoltaic
system or any installation or operating errors.
Whenever the self diagnostic system has identified a particular issue, the
respective status code is shown on the screen.
Important Display of a status code for a short time may be the result of
the control procedures of your Fronius IG Plus unit. If it subsequently
continues to operate normally, there has not been a system error.
Normal operation status
codes
The open-circuit voltage of the
solar modules is too low.
As soon as the open-circuit voltage exceeds 290 V, the Fronius IG Plus
unit starts synchronizing with the grid (display shows ‘SYNCAC’).
The total power output of the solar
modules is insufficient.
After a short time the Fronius IG Plus resumes grid synchronization (display shows ‘SYNCAC’).
Total failure
If the display remains dark after sunrise:
-
Check the open-circuit voltage of the solar modules at the connections of the Fronius IG Plus:
Open-circuit voltage < 290 V ... error in the photovoltaic system
Open-circuit voltage > 290 V ... may indicate a basic fault in the Fronius IG Plus. In this case, notify a Fronius-trained service technician.

stage sets
A special status diagnostic is run if an error occurs in a Fronius IG Plus
with several power stage sets.
It is also possible to call up state messages even if there is no actual error
in existence. This form of status polling may be found in the section ‘The
Setup Menu’.
Display in normal operation
When there is an error in one of the
two power stage sets, the display
flashes between ‘STATE’ and the
corresponding status message
(e.g. ‘STATE 515’)

Warranty and Disposal
FRONIUS USA
limited 10Year Warranty
At Fronius, we have been designing and manufacturing high quality power
electronics equipment for over 60 years. And all our production facilities
are ISO 9001 certified.
You will probably not encounter any service-related issues with your Fronius IG Plus Solar Inverter. However, in the unlikely event that within Ten
(10) years from the original purchase you discover a problem caused by
defects in either workmanship or materials, we will see that it is either
repaired or replaced. Repair or replacement depends on Fronius’ evaluation of the issue and what we decide makes the most sense according to
the situation. The warranty is based on the inverter’s serial number, allowing the warranty to be transferred to another owner if the Fronius IG
Plus Solar Inverter remains installed in the original installation location.
Because the warranty is tied to the serial number, there is no paperwork
to transfer the warranty to a new owner.
The Fronius IG Plus Solar Inverters are designed to withstand normal
operating conditions and typical wear and tear when the Fronius IG Plus
Solar Inverter is used for its original intent, in compliance with the Fronius
IG Plus Installation and Operational Manual(s) supplied with the original
equipment. This warranty does not cover damages by improper installation or operation, misuse, abuse, manipulation, alterations or repair
attempts, accidents, fire, floods, acts of God, and incidental or consequential damage caused by defects with other components of the solar
system. This warranty does not extend beyond the original cost of the
Fronius IG Plus Solar Inverter.
