The inverter operates fully automatically. As soon after sunrise as there is sufficient energy
available from the solar modules, the inverter starts monitoring the grid. When insolation
has reached a sufficient level, the inverter starts feeding energy into the grid.
The inverter operates in such a way that the maximum possible amount of power is ob-
tained from the solar modules.
As soon as the power available has fallen below the level at which energy can be fed into
the grid, the inverter disconnects the power electronics completely from the grid and stops
running. It retains all its settings and stored data.
If the inverter becomes too hot, it automatically reduces the current output power in order
to protect itself.
Reasons for the inverter becoming too hot include the ambient temperature being too high
or inadequate heat dissipation (e.g. if it is installed in a switch cabinet without suitable heat
dissipation).
Proper use/in-
tended purpose
The inverter is intended exclusively to convert direct current from solar modules into alter-
nating current and to feed this into the public grid.
Utilisation not in accordance with the intended purpose comprises:
- Any use above and beyond this purpose
- Making any modifications to the inverter that have not been expressly approved by
Fronius
- the installation of components that are not distributed or expressly approved by Froni-
us.
Fronius shall not be liable for any damage resulting from such action.
No warranty claims will be entertained.
Proper use also includes:
- Carefully reading and obeying all the instructions and all the safety and danger notices
in the Operating Instructions and Installation Instructions
- Performing all stipulated maintenance work
- Installation as specified in the Installation Instructions
When designing the photovoltaic system, ensure that all components are operated within
their permitted operating ranges at all times.
Observe all the measures recommended by the solar module manufacturer to ensure that
the solar module retains its properties in the long term.
Obey the regulations of the power supply company regarding connection methods and en-
ergy fed into the grid.
Warning notices
on the device
There are warning notices and safety symbols on and in the inverter. These warning notic-
es and safety symbols must not be removed or painted over. They warn against incorrect
operation, as this may result in serious injury and damage.
