Explanation/remedy
In case of a high level of solar radiation, the inverter exceeds its
rated current for a short period, depending on the PV genera-
tor.
Select the capacity of the device's backup fuse to be somewhat
higher than the maximum feed-in current (see the "Installa-
tion" section).
› Contact the grid operator if the grid failure continues to oc-
cur.
If the grid fuse trips immediately when the device goes into fe-
ed-in mode (after the start-up period is complete), the device's
hardware is probably damaged.
› Contact KACO Service to test the hardware.
The device continues to operate as normal without losses to
the yield, even when an erroneous daily peak value is displa-
yed. The value is reset overnight.
To reset the value immediately, switch the device off by dis-
connecting it from the grid and switching off the DC, then
switch it back on.
The measuring elements of the device have been selected to
ensure maximum yields. Due to these tolerances, the daily
yields shown may deviate from the values on the feed-in meter
by up to 15%.
› No action.
The PV generator voltage or power is not sufficient for feed-in
(solar radiation is too low). The inverter checks the grid para-
meters before the feed-in process begins. The length of time it
takes to switch back on again differs from country to country,
depending on applicable standards and regulations, and may
be several minutes. The starting voltage may have been set in-
correctly.
› Adjust starting voltage in the Parameter menu.
When there are certain ambient conditions, the devices may
emit audible noises. Grid interference or grid failure caused by
particular loads (motors, machines, etc.) which are either con-
nected to the same point on the grid or located in the vicinity
of the device. Under particular grid conditions, resonances may
form between the device's input filter and the grid; these may
be audible even when the device is switched off. These noise
emissions do not affect the operation of the device. They do
not lead to loss of performance, failure, damage or to a shorte-
ning of the device's service life. People with very sensitive hea-
ring (particularly children) are able to hear the high-frequency
hum caused by the device's operating frequency of approxima-
tely 17 kHz.
