The inverter transforms the direct current
generated by the solar modules into alter-
nating current. This alternating current is
fed into the public grid and synchronized
with the grid voltage that is used there.
The inverter has been designed exclusively for use in grid-connected photovoltaic sys-
tems. It cannot generate electric power independently of the grid.
The inverter provides maximum safety during installation and operation thanks to its design
and function.
The inverter automatically monitors the public power grid. Whenever conditions in the pow-
er grid are inconsistent with standard conditions (e.g., grid switch-off, interruption), your in-
verter will immediately stop operating and interrupt the supply of power into the grid.
Grid monitoring involves monitoring of voltage, frequency, and islanding conditions.
The inverter is fully automatic. As soon as there is enough energy from the solar modules
after the sun rises, the inverter starts grid monitoring. When there is sufficient sunlight, the
inverter starts grid power feed operation.
The inverter works so that the maximum possible output power is taken from the solar mod-
ules.
As soon as the available energy for the grid power feed becomes insufficient, the inverter
completely disconnects the power electronics from the grid and ceases operation. All set-
tings and recorded data are saved.
If the temperature of the inverter becomes too hot, the inverter reduces the current output
power automatically as a protective measure.
Excessive inverter temperatures may be caused by high ambient temperatures or insuffi-
cient heat dissipation (e.g., when installed in switch cabinets lacking appropriate heat dis-
sipation measures).
Intended Use
The solar inverter is designed exclusively to convert direct current from solar modules into
alternating current and feed this power into the public grid.
The following are deemed not to be in conformity with its intended purpose:
-
utilization for any other purpose, or in any other manner
-
alterations to the inverter that are not expressly recommended by Fronius
-
installation of components that are not expressly recommended or sold by Fronius.
The manufacturer is not responsible for any damage resulting from improper use.
All warranty claims are considered void in such cases.
