Choice of location

Proper use The solar inverter is intended exclusively to convert direct current from solar modules into

alternating current and to feed this into the public grid.
Utilisation not in accordance with the intended purpose comprises:

- utilisation for any other purpose or in any other manner

- making any modifications to the inverter that have not been expressly approved by
Fronius

- the installation of parts that are not distributed or expressly approved by Fronius.

Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.

Proper use includes:

- carefully reading and obeying all the instructions and all the safety and danger notices
in the operating instructions

- performing all stipulated inspection and maintenance work

- installation as specified in the operating instructions

When designing the photovoltaic system, ensure that all of its components are operated
within their permitted operating ranges at all times.

Observe all the measures recommended by the solar module manufacturer to ensure the
lasting maintenance of the properties of the solar module.

Obey the regulations of the energy supply company regarding feeding energy into the grid.

General com­ments regarding
choice of location

The following criteria should be taken into account when choosing a location for the invert­er:

Install only on a solid surface

Max. ambient temperatures:

-25 °C / +50 °C

Relative humidity:
0 - 100 %

The airflow within the inverter is
from the left to the top (cold air
taken in from the left, hot air dis­sipated out of the top).

If the inverter is installed in a switch cabinet or a similar sealed area, then forced-air ven­tilation must be provided to ensure adequate heat dissipation.

If the inverter is to be installed on the outer wall of a cattle shed, maintain a minimum all­round clearance of 2 m between the inverter and all ventilation and other openings in the
building.
The installation location must not be exposed to ammonia, corrosive vapours, salts or ac­ids.

Installation notes

Selecting wall
plugs and screws

Recommended
screws

To install the inverter, the manufacturer recommends the use of steel or aluminium screws
with a diameter of 6 - 8 mm.

Mounting the wall
bracket

Mounting the in­verter on a mast

Example of a mast fixing kit

When mounting the inverter on a mast or a
vertical carrier, Fronius recommends the
use of a standard mast fixing kit.

This kit enables the inverter to be mounted
on round or rectangular masts with various
cross-sections.

IMPORTANT! Different fixings may be required to fit the wall bracket depending on the
type of underlying surface. Fixings are therefore not included in the scope of supply of the
inverter. The installer is responsible for selecting the right type of fixing.

NOTE! When mounting the wall bracket, ensure that the wall bracket is not
warped or deformed.

The AC cables can be connected to the AC
terminals without ferrules.

In the case of an AC cable with a cross-section of 16 mm², ferrules can either not be used
or only used to a limited extent depending on the type of ferrule and crimping.

Type of AC cable The following types of AC cable can be connected to the AC terminals of the inverter:

IMPORTANT! The resistance in the leads to the AC-side connection terminals must be as

low as possible for optimal functioning of grid monitoring.

Connecting alu­minum cables

The AC-side terminals are designed for connecting single-wire, round, aluminum cables.
The following points must be taken into account when connecting aluminum cables due to
the non-conducting oxide layer of aluminum:

- Reduced rated currents for aluminum cables

- The connection requirements listed below

Connection Requirements:

Carefully clean off the oxide layer of the stripped end of the cable, e.g., using a knife.

IMPORTANTDo not use brushes, files or sandpaper. Aluminum particles may get stuck
and can transfer to other cables.

After removing the oxide layer of the cable end, rub in a neutral grease, e.g., acid- and
alkali-free Vaseline.

Then immediately connect it to the terminal.

Repeat the steps above whenever the cable is disconnected and then reconnected.

Grid connection
of inverter or
dummy device

IMPORTANT! The PE ground conductor of the AC cable must be laid in such a way that it

is the last to be disconnected in the event that the strain-relief device should fail.
This can be ensured, for example, by making it somewhat longer and by laying it in a loop.

NOTE! Take into account local specifications when configuring cable cross sec­tions.

3

NOTE! To ensure a proper ground connection, all three PE grounding terminals
must be tightened to the specified torque when the inverter is installed.

NOTE! Form loops with the AC cables when connecting them to the AC termi­nals.
When securing the AC cables using a metric screw joint, ensure that the loops do
not protrude beyond the connection area. Under certain circumstances it may oth­erwise no longer be possible to close the inverter.

NOTE!

- Ensure that the grid neutral conductor is grounded. In the case of IT networks
(insulated networks with no grounding) this may not be the case; it will then
not be possible to use the inverter.

- In order to use the inverter, the neutral conductor must be connected.
A neutral conductor that is too small may adversely affect the grid power
feed operation of the inverter. The neutral conductor must therefore be the
same size as the other live conductors.

11

EN

If AC cables are laid over the shaft of the DC main switch or across the connection block
of the DC main switch, they may be damaged when the inverter is swung in, or they may
even prevent the inverter from being swung in.

IMPORTANT! Do not lay AC cables over the shaft of the DC main switch or across the con­nection block of the DC main switch!

E.g.: AC cable

If overlength AC or DC cables are to be laid
in loops in the connection area, attach the
cables with cable ties to the eyelets provi­ded on the top and bottom of the connecti­on block.

NOTE! Local regulations, the energy supply company or other factors may re­quire a residual current protective device (RCD) in the mains line. For this situa­tion, a type A residual current protective device is generally adequate. In
particular cases, and depending on local factors, however, the type A residual
current protective device may trip at the wrong time.
For this reason, Fronius recommends that an RCD suitable for frequency convert­ers be used.

Notes regarding DC connection

General informa­tion about solar
modules

In order to select suitable solar modules and get the most efficient use out of the inverter,
please note the following points:

- The open circuit voltage of the solar modules increases as the temperature decreases
(assuming constant irradiance). Open circuit voltage may not exceed the following val­ues:
Fronius Galvo 1.5-1 ... 420 V
Fronius Galvo 2.0-1 ... 420 V
Fronius Galvo 2.5-1 ... 550 V
Fronius Galvo 3.0-1 ... 550 V
Fronius Galvo 3.1-1 ... 550 V

If the open circuit voltage exceeds the above mentioned values, the inverter may be
damaged, and all warranty rights will become null and void.

- Note the temperature coefficients in the solar module data sheet

- More exact data for sizing the solar array for the particular location can be obtained
using calculations tools such as the Fronius Solar.configurator (available at http://
www.fronius.com).

DC terminals

Max. cross-section of each DC cable:
16 mm²

Min. cross-section of each DC cable:

2.5 mm²

The DC cables can be connected to the DC
terminals without ferrules.

In the case of a DC cable with a cross-section of 16 mm², ferrules can either not be used
or only used to a limited extent depending on the type of ferrule and crimping.

NOTE! Before connecting solar modules, make sure that the voltage specified by
the manufacturer corresponds to the actual measured voltage.
Note the safety instructions and specifications of the solar module manufacturer
regarding solar module grounding.

Connecting alu­minum cables

The DC-side terminals are designed for connecting single-wire, round aluminum cables.
The following points must be taken into account when connecting aluminum cables due to
the non-conducting oxide layer of aluminum:

- Reduced rated currents for aluminum cables

- The connection requirements listed below

Connection Requirements:

Carefully clean off the oxide layer of the stripped end of the cable, e.g., using a knife.

IMPORTANT Do not use brushes, files or sandpaper. Aluminum particles may get stuck
and can transfer to other cables.

After removing the oxide layer of the cable end, rub in a neutral grease, e.g., acid- and
alkali-free Vaseline.

Then immediately connect it to the terminal.

Repeat the steps above whenever the cable is disconnected and then reconnected.

Notes regarding
dummy devices

A dummy device is not suitable for connecting operationally to a photovoltaic system, and
must only ever be used for demonstration purposes. Dummy devices are indicated as such
on their rating plate.

IMPORTANT! Never connect DC cables to the DC connection sockets on a dummy de­vice.

The connection of de-energised cables or sections of cable for demonstration purposes is
permissible.

Inverter DC con­nection

IMPORTANT! Check the polarity and voltage of the solar module strings: the permitted

voltage is:

- Max. 420 V
for Fronius Galvo 1.5-1
for Fronius Galvo 2.0-1

- Max. 550 V
for Fronius Galvo 2.5-1
for Fronius Galvo 3.0-1
for Fronius Galvo 3.1-1

The difference between the individual solar module strings must not exceed 10 V.

NOTE! Take into account local specifications when configuring cable cross sec­tions.

If DC cables are laid over the shaft of the
DC main switch or across the connection
block of the DC main switch, they may be
damaged when the inverter is swung in, or
they may even prevent the inverter from
being swung in.

IMPORTANT! Do not lay DC cables over
the shaft of the DC main switch or across
the connection block of the DC main switch!

Notes regarding the solar module ground in the in­verter

General remarks

Some manufacturers of solar modules sti­pulate that the modules must be grounded.

Fuse holder for solar module ground on the negative
pole

Inside the inverter is a means for grounding
solar modules to the negative pole via a fu­se.
The fuse holder for grounding the solar mo­dules is located on the rear of the inverter.

The inverter can also be operated with solar
modules that need to be grounded to the
positive pole.

IMPORTANT! The fuse in the inverter is not
used for grounding the solar modules to the
positive pole; this has to take place outside
the inverter.

For solar module grounding at the negative pole Fronius recommends following fuse:
nominal current 1A / 600 V, fuse size 10 x 38 mm

IMPORTANT! Fuses for solar module grounding are not included with the inverter. If a so­lar module grounding is required by the solar module manufacturer, a suitable fuse has to
be ordered separately.

Configuring the
inverter for
grounded solar
modules

The inverter's insulation monitoring must be deactivated when the solar modules are
grounded. In the Basic menu, the inverter must therefore be configured so that when the
grounding fuse trips, an error message is displayed or the inverter is switched off (accord­ing to the country setup).
The access code 22742 must be entered to access the Basic menu.

18

Notes regarding the laying of data communication
cables

Laying data com­munication ca­bles

IMPORTANT! Operating the inverter with

an option card and two broken-out option
card divisions is not permitted.
To cater for this eventuality, a relevant
blanking cover (42,0405,2020) is available
from Fronius as an option.

IMPORTANT! Note the following if data communication cables are being introduced into
the inverter:

- depending on the number and cross-section of the data communication cables that
are being introduced, take the relevant blanking plugs out of the sealing insert and in­sert the data communication cable.

- insert without fail the relevant blanking plugs into the free openings on the sealing in­sert.

19

EN

Notes regarding attaching the inverter to the wall
bracket

Attaching the in­verter to the wall
bracket

The side sections of the housing lid are designed to function as holding and carrying han­dles.

The fastening screws in the data communication area of the inverter are used for securing
the inverter to the wall bracket. Correctly tightened fastening screws are a prerequisite if
proper contact is to be established between inverter and wall bracket.

NOTE! For safety reasons, the inverter is fitted with a latch that prevents the in­verter from being swung into the wall bracket unless the DC main switch is
switched off.

- Never attach the inverter to the wall bracket or swing it in unless the DC main
switch is switched off,

- Never use force to attach the inverter or swing it in.

CAUTION! If the fastening screws are not tightened correctly, then the inverter is
at risk of being damaged.
Fastening screws that are not correctly tightened can result in arcs occurring
when the inverter is in operation, which in turn can cause fires. Always use the
specified torque when tightening the fastening screws.

USB Stick as a Data Logger and for Updating Invert­er Software

USB stick as a
data logger

A USB stick connected to the USB A socket can act as a data logger for an inverter.

Logging data saved to the USB stick can at any time

- be imported into the Fronius Solar.access software via the included FLD file,

- be viewed directly in third-party applications (e.g., Microsoft® Excel) via the included
CSV file.

Older Excel versions (up to Excel 2007) have a row limit of 65536.

Data on the USB
stick

If the USB stick is being used as a data logger, three files will be created automatically:

- FRONIUS.sys system file:
This file stores information from the inverter that is irrelevant to the customer. The file
must not be deleted separately. Only delete all of the files (sys, fld, csv) at one time.

- DALO.fld log file:
A log file for reading the data in the Fronius Solar.access software.

Further details on the Fronius Solar.access software can be found in the "DATCOM
Details" operating instructions at http://www.fronius.com

- DATA.csv log file:
A log file for reading the data in a spreadsheet program (e.g.: Microsoft® Excel)

Data structure on the USB stick

(1) USB root directory
(2) Fronius inverters (Fronius Galvo,

Fronius Symo, Fronius Primo or
Fronius Eco)

(3) Inverter number - can be set in the

Setup menu under DATCOM

If there are several inverters with the same
inverter number, the three files will be sa­ved in the same folder. A digit is added to
the file name as a suffix (e.g.: DALO_02.fld)

(9) Additional information

Data volume and
storage capacity

A USB stick with a storage capacity of 1 GB can record logging data for roughly seven
years at a logging interval of five minutes.

CSV file
CSV files can only store 65,535 lines (data records) (up to Microsoft® Excel 2007; there is
no restriction from this version onwards).
At a five-minute logging interval, the 65,535 lines will be written within approximately seven
months (CSV data size of approx. 8 MB).
In order to avoid data loss, the CSV file should be backed up to a PC and deleted from the
USB stick within this seven-month period. If the logging interval is set to a longer period,
this time frame will be increased accordingly.

FLD file
The FLD file should not be larger than 16 MB. This will provide enough storage capacity
for approximately six years at a logging interval of five minutes.
If the file exceeds the 16 MB limit, it should be backed up to a PC and all of the data on the
USB stick should be deleted.

After backing up and removing the data, the USB stick can be reconnected immediately to
resume recording the logging data without any further steps being required.

Buffer memory If the USB stick is unplugged (e.g. for data backup purposes), the logging data is written to

a buffer memory in the inverter.
As soon as the USB stick is plugged in again, the data is copied automatically from the buff­er memory to the stick.

The buffer memory can store a maximum of six logging points. Data is only logged while
the inverter is running (output greater than 0 W). The logging interval is permanently set at
30 minutes. Data can be recorded on the buffer memory for a three-hour time period as a
result.

(8) (9)

NOTE! Using a full USB stick can lead to data loss or data being overwritten.
When using USB sticks, always ensure that there is sufficient storage capacity on
the stick.

23

EN

When the buffer memory is full, the oldest data in the memory will be overwritten by the
next batch of data.

IMPORTANT! The buffer memory requires a permanent power supply.
If there is a power failure while the inverter is in operation, all the data in the buffer memory
will be lost. To avoid losing data during the night, the automatic night switch-off facility must
be deactivated (switch the 'Night Mode' setup parameter to ON - see the section 'Setting
and displaying the menu items', 'Viewing and adjusting parameters in the DATCOM menu
item').

Suitable USB
flash drives

Due to the variety of USB flash drives available on the market, it cannot be guaranteed that
every USB flash drive will be detected by the inverter.

Fronius recommends that only certified USB flash drives suitable for building sites are used
(look out for the USB-IF logo).

The inverter supports USB flash drives with the following file systems:

- FAT12

- FAT16

- FAT32

Fronius recommends that the USB flash drives employed should only be used for record­ing logging data or updating the inverter software. The USB flash drives should not contain
any other data.

USB stick for up­dating the invert­er software

With the help of the USB stick, end customers can also update the inverter software via the
USB item on the SETUP menu: the update file is first saved to the USB stick, from where
it is then transferred to the inverter. The update file must be saved in the root directory on
the USB stick.

USB symbol on the inverter display, e.g. in display mode 'NOW':

If the inverter detects a USB flash drive,
the USB symbol will appear in the top right
corner of the display.

When inserting a USB flash drive, check
whether the USB symbol is displayed (it
may also flash).

NOTE! Please note for outdoor applications that conventional USB flash drives
are often only guaranteed to work within a restricted temperature range. For out­door applications ensure that the USB flash drive also functions, for example, at
low temperatures.

Serial Number Sticker for Customer Use

Serial number
sticker for cus­tomer use

The serial number of the inverter is located
on the rating plate on the bottom of the in­verter.
Depending on the installation position of the
inverter, the serial number can be difficult to
access or read, e.g. if the inverter has been
installed in a dark or shaded area.

Two serial number stickers are enclosed
with the inverter's installation instructions:

* 57 x 20 mm
** 67 x 20 mm

These can be affixed by the customer in a
visible location of his choosing, e.g. on the
front of the inverter or on the operating ins­tructions.
