Symbol Cause
A setting during the initial start-up has failed
because it was not transferred correctly.
The power grid carries no voltage (inverter
stand-alone operation).
For safety reasons, the inverter must not
feed into the power grid.
The inverter switches off while the fault is
present (display is dark).
The residual current that flows from the plus
or minus input via the PV generators to earth
exceeds the permitted value.
Due to normative specifications, the inverter
automatically switches off while the fault is
present.
Despite the reduction in output, the max-
imum permissible temperature has been
exceeded.
The inverter does not feed into the power
grid until the permissible temperature range
has been reached.
