"Fault" messages on the display/LED

Many fault signals indicate a fault in the grid. They are not operational faults of the inverter. The triggering levels are
defined in standards, e.g. VDE0126-1-1. The inverter shuts down if the values exceed or fall below the approved levels.
9.7.1 Display of status and fault messages
Display Fault LED (red)
FS (fault status)
OS (operating status)
Details regarding the fault or operating status can be found either on the display or in the data that was recorded
through the RS485 interface.
9.7.2 Status and fault signals
The following table lists the possible status and fault signals that the inverter shows on the LCD and the LEDs.
BS = operating status, FS = fault status;
B = Action of the operator
E = The indicated work may only be carried out by an authorised electrician.
K = The indicated work may only be carried out by a service employee of KACO new energy GmbH!

• Fault signal relay has switched.
ON
• Feed-in was ended due to a fault.
• The fault signal relay releases again.
OFF
• The inverter feeds back into the grid again after a
country-specific time period.
Explanation
Self-test: The grid parameters and gen-
erator voltage are being checked.
Insufficient generator voltage and
power,
status before the transition to night
shutdown
Checks the shutdown of the power
electronics as well as the grid relay
before feed-in mode.
In case of overheating, the inverter
switches off. Possible causes:
• Excessively high ambient tempera-
ture,
• Fan covered,
• Inverter defective.
Power limitation: If the generator power is too high, the inverter limits
itself to the maximum power (e.g. around noon if the generator capacity
is too large).
The activated grid and system protec-
tion has been tripped.
