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 design and function of the inverter provide a maximum level of safety during
both installation and operation.
The inverter automatically monitors the public grid. Whenever conditions in the
electric grid are inconsistent with standard conditions (for example, grid switch-
off, interruption), the inverter will immediately stop operating and interrupt the
supply of power into the grid.
Grid monitoring is carried out using voltage monitoring, frequency monitoring
and monitoring islanding conditions.
The inverter is fully automatic. Starting at sunrise, as soon as the solar modules
generate enough energy, the inverter starts monitoring grid voltage and fre-
quency. As soon as there is a sufficient level of irradiance, the solar inverter
starts feeding energy into the grid.
The inverter ensures that the maximum possible power output is drawn from the
solar modules at all times.
As there is no longer sufficient energy available to feed power into the grid, the
inverter shuts down the grid connection completely and stops operating. All set-
tings and recorded data are saved.
If the inverter temperature exceeds a certain value, the inverter derates auto-
matically the actual output power for self protection.
The cause for a to high inverter temperature can be found in a high ambient tem-
perature or an inadequate heat transfer away (eg for installation in control cabin-
ets without proper heat dissipation).

Intended Use

The inverter is designed exclusively to convert direct current from solar modules
into alternating current and feed this power into the public grid.

The inverter transforms the direct cur-
rent generated by the solar modules
into alternating AC current. This al-
ternating current is fed into your home

system or into the public grid and syn-
chronized with the voltage that is used
there.
