Faults

11.6.1 Procedure
DANGER
Lethal voltages are still present in the connections and cables of the device even after the device
has been switched off and disconnected!
Severe injuries or death may occur if the cables and/or terminals/busbars in the device are touched.
1. If a fault occurs, notify an appropriately authorized and qualified electrician or KACO new energy GmbH
Service.
2. The operator can only carry out actions marked with a B.
11.6.2 Rectifying the cause
B = Operator's responsibility ; E = The indicated work may only be carried out by an authorised electrician. ; K = The in-
dicated work may only be carried out by a service employee of KACO new energy GmbH!

Explanation/remedy
› Check whether the DC and AC voltages are within the permit-
ted limits (see Technical Data)
› Notify KACO Service.
If the circuit-breakers are defective, the device will recognize
this during the self-test.
› Ensure that there is sufficient PV generator power.
› If the grid separation relay is defective, have it replaced by
KACO Service.
› Notify KACO Service.
Due to a grid fault (over/undervoltage, over/underfrequency),
the device stopped the feed-in process and disconnected from
the grid for safety reasons.
› Change the grid parameters within the permitted operating
limits (see the "Start-Up" section).
In case of a high level of solar radiation, the inverter exceeds its
rated current for a short period, depending on the PV gener-
ator.
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
feed-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 dis-
played. 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.
