For an unlimited individual use of system upgradings, Fronius has de-
veloped the LocalNet. LocalNet is a data network which allows linking
more than one FRONIUS IG units with the system upgrade elements.
LocalNet is a bus system. One single cable is sufficient to allow communi-
cation between one or several FRONIUS IG units with all system upgrade
elements. This reduces the cable requirement to a minimum.
Upgrading the
system
For increased flexibility, all upgradings are also available in a version with
external housing
Additional information
The FRONIUS IG unit is prepared for a whole series of system upgrades,
such as:
- for communicating between FRONIUS IG and outside system extensi-
ons, for example with other FRONIUS IG units
- Data logger (for recording and managing data from your photovoltaic
system by PC) including datalogger and modem connection
- Various large displays (FRONIUS IG Public Display)
- Actuators / Relays / Alarm (FRONIUS IG Signal Card)
- Sensors (Thermo sensors / Irradiance / Metering)
The system upgrades are offered in slot-in boards, similar to those on
your personal computer.
