General
Device concept
The inverter has been designed exclusively for use in grid-connected photovoltaic
systems. It cannot generate electric power independently of the grid.
The inverter automatically monitors the public grid. Whenever conditions in the
electric grid are inconsistent with standard conditions (e.g., grid switch-off, inter-
ruption), your inverter will immediately stop operating and interrupt the supply of
power into the grid.
The grid is monitored by monitoring the voltage, monitoring the frequency and
monitoring islanding conditions.
The inverter is fully automatic. The inverter starts monitoring the grid as soon as
the solar modules are generating enough energy after sunrise. The inverter re-
sumes the grid power feed operation when there is sufficient direct sunlight.
The control system of the inverter ensures that the maximum possible power
output is drawn from the solar modules at all times.
As soon as there is no longer sufficient energy available for the grid power feed
operation, the inverter shuts down the power electronics connection to the grid
completely and stops operating. All settings and recorded data are saved.
When its temperature gets too high, the inverter automatically reduces the cur-
rent output power in order to protect itself.
Reasons for the temperature being too high include a high ambient temperature
or insufficient heat dissipation (e.g., inadequate heat dissipation when installed in
switch cabinets).

The inverter transforms the direct cur-
rent generated by the solar modules
into alternating current. This alternat-
ing current is fed into the public grid
and synchronized with the mains
voltage in use.
