PE	Ground conductor / earthing
L1	Phase conductor
N	Neutral conductor

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

Min. cross-section of each conductor cable:
in accordance with the fuse rating on the AC side, but at least 2.5 mm²

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

IMPORTANT! When using ferrules for AC cables with a cross-section of 16 mm², the ferrules must be crimped with a right-angled cross-section.
The use of ferrules with insulating collars is only permitted up to a max. cable cross-section of 10 mm².

1. Connecting the inverter to the public grid (AC side)

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

Copper or aluminium: solid round conductor Copper: fine-stranded round conductor

1. Connecting the inverter to the public grid (AC side)

The AC-side terminals are suitable for connecting single-wire, round aluminium cables. Because of the formation of a non-conductive oxide layer due to the reaction of aluminium with air, the following points must be considered when connecting aluminium cables:

• the reduced rated currents for aluminium cables
• the connection conditions listed below

Always follow the cable manufacturer instructions when using aluminium cables.

When designing cable cross-sections, take local regulations into account.

Connection conditions:

IMPORTANT! Do not use brushes, files or emery paper, as the aluminium particles get trapped and can be transferred to other conductors.

IMPORTANT!Repeat the procedure if the cable has been disconnected and is to be re-connected.

1. Connecting the inverter to the public grid (AC side)

• Ensure that the grid neutral conductor is grounded. This may not be the case for IT grids (insulated grids with no grounding); 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 inverter feeding energy into the grid. The neutral conductor must therefore be the same size as the other live conductors.

1. Connecting the inverter to the public grid (AC side)

• 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.
  Otherwise, under certain circumstances it may no longer be possible to close the inverter.

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.

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.

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.

1. Connecting the inverter to the public grid (AC side)

NOTE! If solar modules are grounded by a built-in grounding protection device in the inverter, they will not be grounded if the DC main switch is in the OFF position.

• Observe national and international guidelines regarding the connection of aluminium cables
• Follow the instructions of the cable manufacturer.
• Check every year that the cables are securely attached in accordance with the specified torque.

NOTE! The solar modules connected to the inverter must comply with the IEC 61730 Class A standard.

1. Connecting solar module strings to the inverter

In the case of inverters with multiple MPP trackers, there are two independent DC inputs (MPP trackers) available. These can be connected to an unequal number of solar modules.
There are two terminals for DC+ available per MPP tracker. In total there are four terminals for DC-.

Connecting two to four strings in multiple MPP tracker mode:

Connecting two solar module fields to an inverter with multiple MPP trackers

Divide the strings between the two MPP tracker inputs (DC+1/DC+2). The DC- terminals can be used however you wish, as they are internally connected.
When starting for the first time, set MPP TRACKER 2 to "ON" (this can also be done later in the Basic menu).

Single MPP tracker mode on an inverter with multiple MPP trackers:

Connecting multiple interconnected solar module fields to an inverter with multiple MPP trackers using one lead

If the strings are connected using a string collection box and only one bus is used for connection to the inverter, the connection DC+1 (pin 2) and DC+2 (pin 1) must be jumpered.
The cable cross-section of the DC connection lead and the jumpering must be the same. Jumpering of the DC- terminal is not necessary, as these terminals are jumpered internally.

When starting for the first time, set MPP TRACKER 2 to "OFF" (this can also be done later in the Basic menu).

If the inverter with multiple MPP trackers is operated in single MPP tracker mode, the currents from the connected DC leads are divided evenly across both inputs.

Single MPP tracker mode with only one string on an inverter with multiple MPP trackers:

Connecting only one string to an inverter with multiple MPP trackers

If only one string is used for connection to the inverter, the connection DC+1 (pin 2) and DC+2 (pin 1) must be jumpered.
The cable cross-section of the DC connection lead and the jumpering must be the same. Jumpering of the DC- terminal is not necessary, as these terminals are jumpered internally.

When starting for the first time, set MPP TRACKER 2 to "OFF" (this can also be done later in the Basic menu).

If the inverter with multiple MPP trackers is operated in single MPP tracker mode, the currents from the connected DC leads are divided evenly across both inputs.

IMPORTANT! Operating the inverter with one option card and two broken-out option card slots is not permitted.
To cater for this eventuality, a suitable blanking cover (42,0405,2020) is available from Fronius as an option.

IMPORTANT! If data communication cables are wired into the inverter, observe the following points:

• 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 cables.
• The relevant blanking plugs must be inserted into the free openings on the sealing insert.

1Plug the USB flash drive into the data communication area of the inverter

2Open the Setup menu

3Select the "USB" menu item

4Select "Software Update"

5Update the software

If a USB flash drive is connected to the USB A socket it can function as a datalogger for an inverter.

The logging data stored on the USB flash drive can be viewed at any time in third-party programmes (e.g Microsoft® Excel) using the CSV file logged at the same time.

Older versions of Excel (before Excel 2007) are limited to a maximum of 65,536 rows.

If a USB flash drive is connected to the USB A socket it can function as a datalogger for an inverter.

The logging data stored on the USB flash drive can be viewed at any time in third-party programmes (e.g Microsoft® Excel) using the CSV file logged at the same time.

Older versions of Excel (before Excel 2007) are limited to a maximum of 65,536 rows.

1. USB Stick as a Data Logger and for Updating Inverter Software

If the USB flash drive 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 flash drive

(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)

Structure of the CSV file:

1. USB Stick as a Data Logger and for Updating Inverter Software

A USB flash drive 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 flash drive 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 flash drive should be deleted.

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

IMPORTANT! Using a full USB flash drive can lead to data loss or data being overwritten. When using USB flash drives, always ensure that there is sufficient storage capacity on the flash drive.

1. USB Stick as a Data Logger and for Updating Inverter Software

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.

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 Datamanager 2.0 Operating Instructions, section "Setting and displaying the menu items", "Viewing and adjusting parameters in the DATCOM menu item").
On the Fronius Eco or Fronius Symo 15.0-3 208, the buffer memory also functions with just a DC supply.

1. USB Stick as a Data Logger and for Updating Inverter Software

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, industry-grade USB flash drives 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 drive 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 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).

IMPORTANT! 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.

1. USB Stick as a Data Logger and for Updating 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.
