(continued)
The Fronius IG Plus has a basic function for providing minimum and
maximum values on a daily and total basis. These values are shown on
the display.
The display also provides the option of showing the following weather
data:
-
2 different temperature values (e.g. temperature at the solar modules,
outside temperature in the shade)
- Solar radiation
A wide range of data communication elements also enables a multitude of
logging and display options.
The Fronius IG Plus is designed for various system upgrades, e.g.:
-
Upgrades that enable Fronius IG Plus to communicate with external
system upgrades as well as other inverters
- Datalogger (for using a PC to record and manage data from your
photovoltaic system), includes Datalogger and modem interface
- Various large-format displays
- Living room display
- Actuators (e.g.: relays, alarms)
- Sensors (e.g. for temperature, irradiance, energy measurement, etc.)
- Interface cards
System upgrades are available as plug-in cards.
In the event that the heat cannot be dissipated even with the fan working
at maximum speed, a process known as power derating is initiated in
order to protect the Fronius IG Plus (e.g. in switch boxes that do not have
an appropriate heat dissipation system).
A power derating system briefly restricts the output from the Fronius IG
Plus in order to prevent the temperature from exceeding the permissible
value.
The Fronius IG Plus will continue to operate without any downtimes for as
long as possible.

The temperature-controlled and speed-controlled ball bearing fan of the
Fronius IG Plus provides:
-
optimal inverter cooling
- higher efficiency
- cooler components, thus improving service life
- lowest possible energy consumption and lowest possible noise level
