Error Cause Remedy/Explanation
The inverter terminates
grid feeding shortly after
starting-up although
there is enough
insolation.
Defective grid isolation
relay in the inverter.
Although there is enough insolation, the inverter delivers power
for a few seconds only and switches off again. During this short
time a grid feeding value between 0 – 5 W is displayed. If
insufficient generator power can be ruled out in this case the
grid isolation relay is presumably defective and prevents the
inverter from being activated.
Grid fuse triggers Insufficient grid fuse rating
Inverter hardware is
damaged
At times of high insolation the inverter may exceed its rated
current for a short time, depending on the type of solar
generator. Therefore, the grid fuse should have a higher rating
than the max. grid feeding current.
The grid fuse acts immediately if the inverter changes over to
grid feeding (i.e. on termination of the start-up period). In this
case, the inverter hardware is damaged and the device has to
be returned to KACO for repair.
Inverter causes noise Special environmental
conditions
Under special environmental conditions the devices may cause
audible noise. This may be due to the following causes:
- Grid effects and/or grid disturbances caused by special
consumers (motors, machines, etc.), which are connected to
the same grid point or which may be installed in the vicinity of
the inverter.
- Dynamic weather conditions (frequent changes between sun
and clouds) may cause a slight um due to high energy
- Certain grid conditions may result in grid resonance between
the input filter of the device and the grid, which may continue
to be audible even after the inverter is switched off.
- People with very sensitive ears (children, in particular) may
perceive high-frequency hum of the inverter, caused by the
operating frequency of 18 kHz.
- This noise does not affect the operation of the inverter or
inverter performance and will not result in failure, damage or
shorter useful life of the devices.
If any defect found should not be able to be remedied
by means of the measures described above please
contact your solar installation provider or our Service
Department.
Please have the following information ready to enable
our Service Department to respond quickly and
properly:
Inverter Data:
- Serial number of the device
- Inverter type
- Short description of error
- Is the fault or error reproducible? If so, please provide
a short description.
- Does the fault or error occur sporadically?
- Describe the insolation conditions prevailing when the
error occurred.
- Hour of the day
Solar generator data:
- Module type, manufacturer (please send data sheet,
if available).
- Number of modules connected in series
- Number of strings
- Generator power
7 Recycling and disposal
Both the inverter and associated transport packaging
mainly consist of recyclable raw materials.
Device
Defective inverters and accessories do not belong in
your household garbage. Please ensure that the old
device and any accessories are disposed of according
to the applicable regulations.
Packaging
Please ensure that the transport packaging is disposed
of properly.
