Messages on the display and the "Fault" LED

Many fault signals indicate a fault in the grid. They are not operational faults of the inverter. The triggering levels are
defi ned in standards, e.g. VDE0126-1-1. The inverter shuts down if the values exceed or fall below the approved levels.
9.5.1 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.
9.5.2 Status and fault signals
The following table lists the possible status and fault signals that the inverter shows on the LCD and the LEDs. For
the status, consult the data that is logged via the RS485 interface.
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.

Explanation/remedy
If the "priwatt" function is not activated, the potential-free
contact functions as a fault signal relay and therefore indicates
errors. However, if additional devices that are provided for the
"priwatt" function are connected to the inverter via the con-
tact, they can still start up when the inverter experiences an
error, because the contact is connected at that point in time. If
you deactivate the "priwatt" function, we recommend that you
disconnect devices from the inverter that were connected for
this function.

Self-test: The grid parameters and gen-
erator voltage are being checked.
Generator voltage and power are too
low; situation before transition into
night shutdown
Checks the shutdown of the power
electronics as well as the grid relay
before feed-in mode.
Fault signal relay has switched.
Feed-in was ended due to a fault.
The fault signal relay releases again.
The inverter feeds back into the grid again after a
country-specifi c time period.
