General
Fronius Solar Net
- Basics
Fronius Solar Net is the basis for unlimited, individual application of DATCOM compo-
nents. Fronius Solar Net is a data network which enables several Fronius inverters to ex-
change data with DATCOM components.
The Fronius Solar Net data network operates as a ring-shaped bus system. A single data
link between the individual components enables communication between one or more Fro-
nius inverters and the DATCOM components. This minimizes the cabling effort for the in-
dividual DATCOM components.
DATCOM / Plug-in
card principle
DATCOM components are available as plug-in cards (similar to the PC). Depending on the
country setup, Fronius inverters can be equipped with up to three plug-in cards within the
housing.
Plug-in cards communicate within the inverter via its internal network. External communi-
cation to Fronius Solar Net takes place via Fronius Com Cards.
DATCOM compo-
nents with exter-
nal housing
For increased flexibility, DATCOM components are also available in versions with an ex-
ternal housing (box).
DATCOM components with external housings are designed in accordance with degree of
protection IP 20. For this reason, they are suitable for interior applications only or must be
placed in an appropriately rated weather-proof housing.
If required, the base of an external housing can be clipped onto a commercially-available
DIN rail.
DATCOM components with external housings are equipped with an input „IN“ and output
„OUT“ for data communication within the network.
Maximumnumber
of DATCOM com-
ponents and in-
verters
The following maximum number of DATCOM components and inverters can be connected
to a total system (as of May 2008):
- 100 Fronius inverters (Fronius IG, Fronius IG Plus, Fronius IG Plus V, Fronius IG TL,
Fronius CL or Fronius Agilo - different models can be combined)
- 1 Datalogger pro or easy card / box or Datalogger Web or Fronius Personal Display DL
- 1 Fronius Power Control Card / Box
- 10 sensor cards / boxes
- 10 public display cards / boxes
- 1 interface card / box
- 200 string controls
However, the system is designed to be easily upgradeable as new DATCOM components
are developed.

Core of Fronius
Solar Net: the Da-
talogger
The core of Fronius Solar Net is the Datalogger. It coordinates data transmissions and en-
sures that even large volumes of data are distributed and stored quickly and securely. In
addition, the Datalogger also records data for the entire system over long periods of time.
The following devices have a Datalogging function:
-Fronius Datalogger pro
The Datalogger pro can record data from up to 100 inverters and 10 sensor cards/
boxes.
-Fronius Datalogger easy
The Datalogger easy can only record data from the inverter and sensor card / box us-
ing Address 1.
-Fronius Datalogger Web
The Datalogger Web can record data transmitted via the Internet from up to 100 in-
verters and 10 sensor cards/boxes.
-Fronius Personal Display DL Box
The Fronius Personal Display DL Box can record data from up to 100 inverters and
one sensor card/box.
The Fronius Datalogger easy / pro has
- two data interfaces for direct data transfer to the PC (RS232 and USB)
- one data interface for remote PC data queries via modem and telephone line (RS232)
The Fronius Datalogger Web has a 10/100 MBit Ethernet interface.
Fronius Com
Cards for con-
necting inverters
to Fronius Solar
Net
Fronius Com Cards provide the data link from a Fronius inverter to Fronius Solar Net and
to the DATCOM components connected to it. In addition, Fronius Com Cards also offer gal-
vanic isolation between the photovoltaic ystem and the inverters providing additional safe-
ty. Fronius Com Cards must be installed in each inverter connected to Fronius Solar Net.
Each Fronius Com Card is equipped with two RS 422 interfaces - an input and an output.
The input is labeled „IN“ and the output is labeled „OUT.“
IMPORTANT! In the rest of this manual, the Datalogger pro, Datalogger easy and Data-
logger Web are only referred to specifically if the information relates solely to that version.
The term "Datalogger" is used on its own for information that relates to Datalogger pro, Da-
talogger easy and Datalogger Web.
NOTE! Every Fronius inverter to be monitored using a datalogger requires a
COM Card, even if the system only contains one Fronius inverter. In this case, the
Fronius Com Card serves as a link between the internal network of the inverter
and the Fronius Solar Net interface of the datalogger.

Mains supply to DATCOM components
General Power is supplied to DATCOM components independently of the inverter. This ensures a
power supply when there is no power from the photovoltaic modules. Power is supplied to
DATCOM components via Fronius com cards or plug-in power packs. This is particularly
important when using a Fronius Sensor Card because this ensures that the datalogger will
be able to record all data even at night.
Power supply to
DATCOM compo-
nents via Fronius
Com Card
Fronius Com Cards are responsible for powering DATCOM components. The integrated
power supply of a Fronius Com Card is implemented via special contacts in the slot, which
continue to supply power even when there is no power from the photovoltaic modules.
Fronius Com Cards version 1.7 and higher are equipped with a switchedmode power sup-
ply and can be used with several supply voltages (208 V / 220 V / 230 V / 240 V / 277 V).
Up to version 1.4B:
Item number 4,070,769
(1) AC fuse
Version 1.7 and higher:
Item number 4,070,913
(1) Jumper
WARNING! An electric shock can be fatal. Danger of an electrical shock due to
insufficient dimensioning for US-specific grid voltages. Fronius Com Cards up to
version 1.4B (item number 4,070,769) cannot be used with the Fronius IG Plus
USA.

11
EN-US
One Fronius Com Card can supply three additional DATCOM components, or one addi-
tional DATCOM component if it is located in a Datalogger Web. Because the power is sup-
plied via the data cable, the DATCOM components in an external housing are also
supplied.
Checking the
power supply via
Fronius Com
Cards
Once cabling and installation of system components is complete, including the network
connection to all inverters, the green LED should light up on all Fronius Solar Net clients.
If this is not the case:
- Check cable connections
- Check that all inverters are connected to the network
If the green LED is not lit for individual system components:
- Plug another power pack into the corresponding DATCOM component
Power pack Each DATCOM component with external
housing and the Fronius Com Card is
equipped with a 12 V power pack connecti-
on socket.
If there is a Fronius Datalogger Web in Solar Net, the Fronius Com Card can only supply
one additional DATCOM component, e.g., inverter + Fronius Datalogger Web + Fronius
Sensor Box. One power pack can supply up to eight DATCOM components. No additional
supply cables are needed for this. The data communication cable is used to provide power
between components.
NOTE! When using more than 12 inverters in a system, the power supply can be
deactivated for individual Fronius Com Cards to decrease the power consumption
for the DATCOM.
IMPORTANT! Once the power has been turned on, the Fronius Com Card requires ap-
prox. 10 s until the green LED lights up.
NOTE! If a system only has one
inverter but more than 3 DATCOM
components, the Fronius Com
Card in the inverter may not pro-
vide sufficient power for all DAT-
COM components. This means
that the green LED would not light
up on all DATCOM components.
In this case, the additional power
pack should be plugged into one
of the DATCOM components with
no green LED.

12
IMPORTANT! The scope of delivery for the power pack includes a power adapter for the
following regions:
- Australia
-EU
-UK
- USA
NOTE! The power pack available from Fronius was designed specifically for
DATCOM components. Do not use any other power pack.

Defining system components in Fronius Solar Net
General Fronius Solar Net will recognize different DATCOM components automatically (datalogger,
sensor card, etc.). However, there is no automatic distinction between several identical
DATCOM components. For this reason, each system component must have an individual
number (address) to uniquely identify each system component in Fronius Solar Net (invert-
er or DATCOM component).
Fronius inverters give you the option to set the address directly on the display. However,
some versions of Fronius IG are not equipped with a display. In this case, the address can
be set via two keys.
DATCOM components are equipped with a special setting wheel for addresses. A small
screwdriver is required for this.
Setting the ad-
dress on the in-
verter
Please see the inverter operating instructions for setting the inverter address.
Setting the ad-
dress on DAT-
COM components
Proceed as follows for all DATCOM components (whether card or box):
Turn the setting wheel (1) to the desired address using a screwdriver
Example:
- Permitted:
Fronius IG „Adress 1“, Sensor Card „Adress 1“
- Not permitted:
Fronius IG 20 „Adress 1“, Fronius IG 30 „Adress 1“
1
(1)
IMPORTANT! You do not have to set the
address for the datalogger because there is
always only one datalogger per system.
NOTE! Two identical devices should never have the same address in a network.
