Do not install the inverter:
- where it may be exposed to ammonia, corrosive gases, acids or
salts
(e.g., fertilizer storage areas, vent openings for livestock stables,
chemical plants, tanneries).
During certain operation phases the inverter may produce a slight noise.
For this reason it should not be installed in an occupied living area.
Do not install the inverter in:
- 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.
The inverter is designed to be dustproof in principle. However, in areas
of high dust accumulation, the cooling surfaces can become dusty, which
can impair the thermal performance. In this case, the dust must be removed regularly. We therefore recommend that installation is not carried
out in areas and environments with high dust accumulation.
Do not install the inverter in:
- greenhouses
- storage or processing areas for fruit, vegetables, or viniculture products
- areas used in the preparation of grain, green fodder, or animal

Notes on grid connection
Monitoring the
Grid
AC Connection
IMPORTANT! The resistance in the leads to the AC-side connection terminals must be as
low as possible for optimal functioning of grid monitoring.
NOTE! Fronius Primo 3.8–8.2 only:
To ensure a proper ground connection, all 3 grounding terminals GND must be
tightened with the specified torque during installation.
NOTE! Loop the AC cables when connecting them to the AC terminals:
Fronius Primo 3.8–8.2: min. 4 in. (102 mm)
Fronius Primo 10.0–15.0: in accordance with NEC
IMPORTANT! The ground conductor GND of the AC cable must be laid so that it is disconnected last.
Measure the ground conductor GND longer, for example, and loop.
If AC cables are laid over the shaft of the
DC main switch or across the DC main
switch connection block, the cables may be
damaged when the inverter is pivoted or the
inverter may not be able to be pivoted.
IMPORTANT! Do not lay AC cables over
the shaft of the DC main switch or across
the DC main switch connection block!
Example: Fronius Primo 3.8–8.2
Example: AC cables (Fronius Primo 3.8–8.2)

NOTE! A residual current circuit breaker for the AC connecting cable may be re-
quired depending on local regulations, the power supply company as well as other conditions. A type A residual current circuit breaker with a trip current of at least
100 mA is generally sufficient in this case. Nevertheless, false alarms can be triggered for the type A residual current circuit breaker in individual cases and depending on local conditions.
For this reason, Fronius recommends that you use a residual current circuit
breaker suitable for a frequency converter.
Depending on the installation, an additional external AC and/or DC disconnect may be required if the inverter is installed in a location not easily accessible to utility or fire personnel.
Contact your local authorities for additional information.

Notes on DC Connection
General Information about Solar
Modules
Inverter DC Connection
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).
- Note the temperature coefficients in the solar module data sheet.
- More exact data for sizing the solar modules can be obtained using calculation tools
such as the Fronius Configuration Tool (available at http://www.solarweb.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.
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.
The inverter is designed exclusively to be
connected and used with nongrounded solar modules.
The solar modules cannot be grounded at
either the positive or negative pole.
Multi MPP Tracker Inverter – Fronius Primo 3.0–
8.2
IMPORTANT! Check the polarity and voltage of the solar module strings.
If DC cables are laid over the shaft of the
DC main switch, or across the DC main
switch connection block, they could be damaged when the inverter swivels in, or the
inverter could be prevented from swiveling
in.
IMPORTANT! Do not lay the DC cable over
the DC main switch or across the DC main
switch connection block.
Multi MPP Tracker inverters have 2 independent DC inputs (MPP Tracker). These inputs
can be connected to a number of different modules.

USB Stick as a Data Logger and for Updating Inverter Software
USB stick as a
data logger
Data on the USB
stick
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.
If the USB stick is used as a datalogger, three files are automatically created:
- FRONIUS.sys system file:
This file saves information from the inverter that is irrelevant to the customer. The file
must not be deleted individually. Only delete all files together (sys, fld, csv).
- DALO.fld log file:
Log file for reading out data in Fronius Solar.access.
You can find additional information on the Fronius Solar.access Software in the "DATCOM Detail" operating instructions at http://www.fronius.com
- DATA.csv log file:

Data Quantity and
Memory Capacity
One USB stick with a memory capacity of 1 GB, for example, can record logging data at a
logging interval of 5 minutes for approx. 7 years.
CSV file
CSV files can store only 65535 rows (data records) (up to Microsoft® Excel version 2007,
afterwards there is no limit).
At a logging interval of 5 minutes, the 65535 rows are written within approx. 7 months (CSV
data size of approx. 8 MB).
To avoid a loss of data, the CSV file should be backed up to a PC within these 7 months
and deleted from the USB stick. If the logging interval is set longer, this time frame is extended accordingly.
FLD file
The FLD file should not be larger than 16 MB. At a logging interval of 5 minutes, this corresponds to a storage duration of approx. 6 years.
If the file exceeds this 16 MB limit, it should be backed up to a PC, and all data should be
deleted from the USB stick.
After you have backed up the data and removed it from the USB stick, the stick should be
immediately reinserted so that it can record logging data; no further steps are required.
NOTE! A full USB stick can lead to the loss of data or the overwriting of data.
When inserting the USB stick, make sure that it has a sufficient memory capacity.
Buffer Memory If the USB stick is removed (e.g. to back up data), the logging data are written to a buffer
memory in the inverter.
As soon as the USB stick is reinserted, the data are automatically transferred from the buffer memory to the USB stick.
The buffer memory can store a maximum of 6 logging points. Data are logged only during
inverter operation (power greater than 0 W). The logging interval is fixed at 30 minutes.
This leads to a timeframe of 3 hours for recording data to the buffer memory.
When the buffer memory is full, the oldest data in the buffer memory are written over with
the new data.
29
IMPORTANT! The buffer memory requires a constant power supply.
If there is an AC power outage during operation, all data in the buffer memory are lost. The
automatic night switch-off must be deactivated so that the data are not lost at night (set
"Night Mode" to ON – see chapter "Setting and Displaying Menu Items," section "Displaying and Setting Parameters in the 'DATCOM' Menu Item").
On the Fronius Eco, the buffer memory also functions with just a DC supply.
Suitable USB
Sticks
Due to the number of USB sticks on the market, we cannot guarantee that every USB stick
will be recognized by the inverter.
Fronius recommends using only certified, industrial USB sticks (look for the USB-IF logo).
The inverter supports USB sticks using the following file systems:
- FAT12
- FAT16
- FAT32
Fronius recommends that the USB stick only be used for recording logging data or for updating the inverter software. USB sticks should not contain any other data.
USB symbol on the inverter display, e.g., in the "NOW" display mode:
When the inverter recognizes a USB stick,
the USB symbol will appear at the top right
of the display.
When inserting the USB stick, make sure
that the USB symbol is displayed (it may
also be flashing).

AC Output Power
NOTE! Please be aware that in outdoor applications the USB stick may only function in a limited temperature range. Make sure, for example, that the USB stick
will also function at low temperatures for outdoor applications.
The USB stick can be used to help end customers update inverter software via the USB
menu item in the SETUP menu item: the update file is first saved on the USB stick and then
transferred to the inverter. The update file must be saved in the USB stick root directory.

Notes on Maintenance
Maintenance
Maintenance and repair work must only be carried out by authorised personnel.
Cleaning The inverter and the display can be cleaned with a damp cloth if necessary.
Do not use any cleaning agents, abrasive cleaners, or solvents to clean the inverter.
NOTE! For horizontal installation positions and when installing outside:
check once per year that all screws are secured tightly.
