Explanation
!
The voltage of a grid phase is too high,
the grid cannot be fed into.
The phase experiencing failure is dis-
played.
The voltage of a grid phase is too low;
the grid cannot be fed into. The phase
experiencing failure is displayed.
The voltage of a grid phase is too high,
the grid cannot be fed into.
The phase experiencing failure is dis-
played.
The measured line-to-line voltage is
outside of the tolerance limits.
Grid frequency is too low.
This fault may be grid-related.
Grid frequency is too high.
This fault may be grid-related.
The grid voltage measurement accord-
ing to EN 50160 has exceeded the
maximum permitted limit value.
This fault may be grid-related.
Waiting time of the inverter after a
fault.
The temperature inside the unit was
too high. The inverter switches off to
prevent damage to the hardware.
A fault occurred during a self-test.
The inverter does not begin feeding
into the grid until the PV voltage falls
below a specifi ed value.
The external Power Control limit was
activated by the grid operator. The
inverter limits its power.
P(f)/frequency-dependent power
reduction: Frequency-dependent power
reduction will be activated when the
BDEW (German Association of Energy
and Water Industries) Medium Voltage
Directive goes into eff ect. Power reduc-
tion starts at a frequency of 50.2 Hz.
Output current limiting: The AC current
is limited once the specifi ed maximum
value has been reached.
