Fault
Cause of fault
Explanation/remedy
By
The inverter is
active but does
not feed into the
grid. Display:
“Waiting for
feed-in”
•
Array voltage
too low
•
Grid voltage
or PV array
voltage
unstable.
•
The PV array voltage or power is not suffi
cient for feed-in
(solar irradiance is too low).
•
The inverter checks the line parameters before the feed-in
process begins. The length of the switch-on time diff ers by
country according to applicable standards and regulations
and can take several minutes.
•
The starting voltage may have been set incorrectly.
Adjust starting voltage in the Parameter menu if required.
E
Noise emission
from the inverter.
Particular ambient
conditions.
When there are certain ambient conditions, the units may emit
audible noises.
•
Line interference or grid failure caused by particular loads
(motors, machines, etc.) which are either connected to the
same point on the grid or located in the vicinity of the
inverter.
•
In cases of volatile weather conditions (frequent switching
between sunny and cloudy conditions) or strong irradiance,
a light hum may be audible due to the increased power.
•
Under particular grid conditions, resonances may form
between the unit’s input fi lter and the grid, which may be
audible even when the inverter is switched off .
These noise emissions do not aff ect the operation of the
inverter. They do not lead to loss of effi
ciency, failure, damage
or to a shortening of the unit’s service life.
People with very sensitive hearing (particularly children) are
able to hear the high-frequency hum caused by the inverter’s
operating frequency of approximately 17 kHz.
No action.
