Fault Cause of fault Explanation/remedy By
The line fuse
trips. The line fuse
capacity is too
low.
In cases of high irradiance, the inverter exceeds its rated cur-
rent for a short period, depending on the PV generator.
 Select the capacity of the inverter’s pre-fuse to be some-
what higher than the maximum feed-in current (see the
“Installation” section).
E
 Contact the grid operator if the grid failure constantly
occurs.
E
Damage to the
inverter’s hard-
ware.
If the line fuse trips immediately when the inverter goes into
feed-in mode (after the start-up period is complete), the invert-
er’s hardware is probably damaged.
 Contact KACO Service to test the hardware. E
The inverter dis-
plays an impos-
sible daily peak
value. Faults in the grid. The inverter continues to operate as normal without losses to
the yield, even when an erroneous daily peak value is dis-
played. The value is reset overnight.
 To reset the value immediately, switch the inverter off by
disconnecting it from the grid and switching off the DC,
then switch it back on.
E
Daily yields do
not correspond to
the yields on the
feed-in meter. Tolerances of
the measuring
elements in the
inverter.
The measuring elements of the inverter have been selected
to ensure maximum yields. Due to tolerances, the daily yields
shown may deviate from the values on the feed-in meter by
up to 15%.
 No action. -
The inverter is
active but does
not feed into
the grid. Display:
“Waiting for
feed-in” • Generator volt-
age too low
• Grid voltage or
PV generator
voltage unsta-
ble.
• The PV generator 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.
