The Fronius IG Plus Unit in the PV System
General The solar inverter is the highly complex link between the solar modules and the public grid.
Tasks The main tasks of the inverter include:
- Converting DC to AC current
- Fully automatic operational management
- Display function and data communication
Converting DC to
AC Current
The inverter transforms the direct current generated by the solar modules into alternating
current. This alternating current is fed into your home system or into the public grid and
synchronized with the voltage that is used there.
Fully Automatic
Operational Man-
agement
The inverter is fully automatic. Starting at sunrise, as soon as the solar modules generate
enough power, the automatic control unit starts monitoring voltage and frequency. After
five minutes, if there is a sufficient level of irradiance, your solar inverter starts feeding en-
ergy to the grid.
The inverter control system ensures that the maximum possible power output is drawn
from the solar modules at all times.
This function is called MPPT (Maximum Power Point Tracking).
As dusk starts and there is no longer sufficient energy available to feed power into the grid,
the inverter unit shuts down the grid connection completely and stops operating. All set-
tings and recorded data are saved.
Display function
and data commu-
nication
The display on the inverter is the interface between the inverter and the operator. The de-
sign of the display is geared towards simple operation and making system data available
as long as the inverter operates.
The inverter is equipped with a basic logging function to monitor minimum and maximum
data on a daily and a cumulative basis. These values are shown on the display.
A wide range of data communication products allows for many possibilities of recording
and viewing data.
System Upgrade The inverter is designed for various system upgrades, e.g.:
- Upgrades that enable the inverter to communicate with external system upgrades as
well as with other inverters
- Datalogger (when using a PC to record and manage data from your photovoltaic sys-
tem), includes Datalogger and a modem interface
IMPORTANT! The inverter has been designed exclusively for use in grid-connected pho-
tovoltaic systems. It cannot generate electric power independently of the grid.
