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.
Maximum number
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.
