Q3 ENERGIE Installation and operating instructions QX³ series
Version 1.0, Stand 27.04.2015
Meaning
The inverter is limiting the feed-
in power because the inverter
temperature is too high
Shutdown due to
overtemperature
At least one temperature sensor
has detected overtemperature
Shutdown due to asynchrony
Shutdown due too low
frequency
Shutdown due too high
frequency
Shutdown due too low grid
voltage
Shutdown due too high grid
voltage
Shutdown due to high 10min
Shutdown due to large steady
component in output current
Self-test was not successful
Non-permissible high leakage
current
Impermissibly low earth
resistance
Irreparable internal fault,
inverter no longer operative
The DC input current of the PV
is higher than the maximum
permissible string input current.
Can be a normal operating
status if a high generator
output power has been selected
compared to the inverter
power.
The DC input voltage of the PV
Remedial measure
Clean fan openings, check
installation site
Clean fan openings, check
installation site
Check grid for frequency
fault/PLL fluctuations; check
grid quality
Check grid connection and
grid quality; if necessary
contact grid operator
Check grid connection and
grid quality; if necessary
contact grid operator
Check downstream
switching elements for
triggering. Check grid
connection and grid quality
and contact grid operator if
necessary.
Check connection and grid
quality.
Overvoltage could have
occurred due to local grid
conditions. Contact the grid
operator if this event occurs
repeatedly
Check connection and grid
quality.
Overvoltage could have
occurred due to local grid
conditions. Contact the grid
operator if this event occurs
repeatedly
If this fault message is
persistent, please contact
the Service Department
If this fault message is
persistent, please contact
the Service Department
Check PV side and other
installations for
earth connection.
Rectify the earth fault before
reconnecting.
Immediately disconnect the
DC switch on the underside
of the inverter housing from
the inverter (DC
disconnecter switch in
position off).
Check PV installation for
earth fault. Rectify the earth
fault before reconnecting.
If this fault message is
persistent, please contact
the Service
If applicable check the
dimensioning string
of the
generator and
interconnection of the PV
modules.
Immediately disconnect the
