Device concept
The inverter has been developed exclusively for use in grid-connected photovoltaic sys-
tems; it is impossible to generate energy independently of the public grid.
The inverter automatically monitors the public grid. In the event of abnormal grid condi-
tions, the inverter ceases operating immediately and stops feeding power into the grid
(e.g. if the grid is switched off, if there is an interruption, etc.).
The grid is monitored by monitoring the voltage, frequency and islanding conditions.
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
obtained 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.
WARNING!
If not avoided, death or serious injury may result.
CAUTION!
If not avoided, minor injury and/or damage to property may result.

Data communication cover
The inverter transforms the direct current
generated by the solar modules into
alternating current. This alternating current
is fed into the public grid synchronously
with the grid voltage.
