Safety Precautions at the Machine Location
Ensure when installing machines with cooling-air vents that the cooling air can flow freely
through the air vents without obstruction. Only operate the machine with the degree of
protection specified on the rating plate.
Mains connection
High-performance devices (> 16 A) can affect the voltage quality on the mains
network because they can feed powerful current into the main supply.
This may affect a number of types of device in terms of:
- connection restrictions
- criteria with regard to maximum permissible mains impedance
*)
- criteria with regard to minimum short-circuit power requirement
*)
*)
at the interface with the public mains network
see Technical Data
In this case, the plant operator or the person using the device should check
whether or not the device is allowed to be connected, where appropriate
through discussion with the power supply company.
EMC device
classifications
Devices with emission class A:
- are only designed for use in an industrial setting
- can cause conducted and emitted interference in other areas.
Devices with emission class B:
- satisfy the emissions criteria for residential and industrial areas. This
also applies to residential areas in which power is supplied from the
public low-voltage grid.
EMC device classification as per the rating plate or technical specifications
EMC measures In certain cases, even though a device complies with the standard limit
values for emissions, it may affect the application area for which it was
designed (e.g. when there is sensitive equipment at the same location, or if
the site where the device is installed is close to either radio or television
receivers).
If this is the case, then the operator is obliged to take appropriate action to
rectify the situation.
Information on
noise emission
values
The inverter generates a maximum sound power level of <80 dB(A) (ref. 1pW)
when operating under full load in accordance with IEC 62109-1.
The device is cooled as quietly as possible with the aid of an electronic temperature control system, and depends on the amount of converted power, the
ambient temperature, the level of soiling of the device, etc.
It is not possible to provide a workplace-related emission value for this device
because the actual sound pressure level is heavily influenced by the installation situation, the power quality, the surrounding walls and the properties of the
room in general.

Only FRONIUS service staff are authorized to carry out repairs to the
FRONIUS IG unit.
Repair
The design and function of the FRONIUS IG unit offers a maximum
level of safety, both during installation as well as in operation. A complete galvanic isolation between the DC and AC sides is one such
safety feature.
The FRONIUS IG provides galvanic isolation and grid monitoring.
The passive and active measures for the protection of persons and
equipment help ensure safe installation and operation.
Galvanic
isolation
Whenever conditions in the electric grid are inconsistent with standard conditions (for example grid switch-off, interruption, etc.), your
FRONIUS IG unit will immediately stop operating and interrupt the
supply of power into the grid.
Your FRONIUS IG unit determines the grid’s status by:
- monitoring voltage
- monitoring frequency
- monitoring islanding conditions
This scheme prevents dangerous voltages at the AC lines and constitutes an essential contribution towards avoiding hazards for the
maintenance staff.
Monitoring
the grid
Before connecting the solar modules, you must check whether the
voltage parameters specified in the manufacturer’s data correspond
with the actual parameters.
When checking the voltage reading, please take into account that
solar modules supply a higher open circuit voltage when temperatures are low and sunlight level remains unchanged.
The data sheet of the solar module will tell you the temperature factors applicable for ascertaining the theoretical open-circuit voltage at
14 °F (-10 °C).
If the solar modules exceed an open-circuit voltage of 500 V, regardless of temperature the FRONIUS IG unit might be damaged and all
warranty rights will be voided.

Your FRONIUS IG unit complies with the requirements for "Inverters,
converters and controllers for use in independent power systems"
UL1741-2005 and IEEE 1547 standards. The ground-fault detection
and interruption is in compliance with NEC 690 building code requirements.
The respective conformity declarations can be found in the appendix
to these operating instructions.
Only appropriately licensed contractors are authorized to connect
your FRONIUS IG to the grid. Consult your local authorities for specific requirements.
Before connecting the FRONIUS IG to the grid, permission for the
connection must be granted by the utility company.

The energy from worldwide sunlight amounts to a total of about
1,540,000,000,000,000,000 kWh/year (1,540 Peta kWh/year). This is
15,000 times as much as the electricity consumption worldwide. We
congratulate you on your decision to actively use world’s biggest
energy resource. The word "photovoltaic" comes from the driving
force behind this technology, which is light. When light strikes photovoltaic cells, a voltage and current is created.
General information
How a photovoltaic system works

The FRONIUS IG is the latest generation of solar inverter. It is the
highly complex link between solar modules and the grid.
As such it is responsible for a number of high-level tasks. The following diagram gives a graphical overview as to where the FRONIUS
IG is placed in the PV system.

Operation manual
The FRONIUS IG 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. The FRONIUS IG has been designed
exclusively for use in grid connected photovoltaic systems. It cannot
generate electric power independent from the grid.
Converting
DC into AC
current
9
The FRONIUS IG has been designed for use with solar modules of a
wide range of input voltages. This allows the use of the greatest
variety of types of solar modules. Important notice: the parameters
indicated for maximum DC voltage (total voltage of the solar modules
connected) must at no time be exceeded!
By its design and operation, the FRONIUS IG offers maximum safety
during installation as well as in operation.
The FRONIUS IG is equipped with an HF-transformer (HF = high
frequency) that ensures galvanic isolation between the DC side and
the grid. In addition, the HF principle results in a drastic reduction of
the transformer’s size, which means that it requires less space and
has considerably less weight. The FRONIUS IG unit achieves a high
degree of efficiency due to its innovative circuit schemes.
Voltage transformation
and galvanic
isolation
The FRONIUS IG unit monitors the grid. This responsibility comprises all measures necessary for the protection of persons and machines in case of a power blackout or other grid loss.
The FRONIUS IG unit is programmed to stop operation immediately
and stop supplying power whenever conditions in the grid deviate
from standard conditions (for example, when power is switched off or
in case of any other kind of interruption).
The FRONIUS IG 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 insolation, your solar inverter starts feeding energy to
the grid. A few Watts of solar power output are sufficient to achieve
this.
The control system of the FRONIUS IG 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). It
operates with extremely high precision. As dusk starts and there is
no longer sufficient energy available to feed power into the grid, the
FRONIUS IG unit shuts down the grid connection completely and
stops operating. All settings and data recorded are saved.

The FRONIUS IG unit comes standard with a display that has been
designed to enable quick and easy access to the most important
data in your PV system.
The FRONIUS IG is equipped with a basic logging function to monitor minimum and maximum data on a daily and a cumulative basis.
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
In addition to the functions installed in the FRONIUS IG unit, a wide
choice of data communication products allows for many possibilities
of recording and visualizing data. The respective components required to upgrade the system are easy to install.
With each additional parameter, that is controlled directly by the
inverter, installation becomes easier and less costly because no
additional peripheral equipment will be required. Based on our experience and the use of the most innovative technologies, the FRONIUS IG unit is able to manage all system parameters simultaneously.
In addition, the FRONIUS IG unit complies with a wide range of
requirements established for the safety of people and other household appliances, as well for its own protection.
Some of these requirements are:
- ability to monitor the grid
- the quality of the electricity supplied
- immunity from outside disturbance and interference (for example,
from mobile telephones).
Your advantage
There are several ways the FRONIUS IG unit can identify a gridcutoff, by monitoring:
- voltage
- frequency
- islanding conditions

Product description
The FRONIUS IG Unit
The FRONIUS IG unit is designed for fully automatic operation. No
manual control is necessary for feeding the power it generates into
the grid.
The FRONIUS IG unit starts operating automatically as soon as the
power output of the solar modules is sufficient after sunrise.
During its operation the FRONIUS IG unit optimizes the voltage of
the solar modules for maximum power output.
- the optimal voltage for any particular solar module is called MPP
voltage (MPP = maximum power point)
- maintaining the exact MPP voltage guarantees an optimal level of
efficiency for your modules at any time (MPP-tracking).
As soon as dusk begins there is no longer sufficient energy available
to feed into the grid. The FRONIUS IG unit fully shuts off the grid
connection at this time.
- during the night the FRONIUS IG unit draws less than 150 mW
from the grid
- the data and parameters are saved
- it is also possible to shut the unit off manually
How it functions
After switching on automatically, the FRONIUS IG unit goes through
a self-test, followed by an extensive test of the grid. This test takes
five minutes. During the startup sequence the LED illumination is
yellow.
