Code Description Behaviour Remedy
143 Emergency power overload Emergency power mode is
interrupted. The inverter
attempts to start emer-
gency power mode three
times; if this is unsuccess-
ful status code 145 is dis-
played
Check emergency power
circuit; if this status code
keeps recurring, contact
your system fitter 144 Emergency power short-
circuit
145 Status code 143 or 144
has occurred more than
three times
Status codes –
Class 3 Class 3 includes status codes that may occur while feeding energy into the grid,
but generally do not cause the process to be interrupted for any length of time.
The inverter disconnects automatically from the grid, the grid is then monitored
as specified and the inverter attempts to resume feeding energy into the grid.
Code Description Behaviour Remedy
301 Overcurrent (AC) Short-term interruption
while feeding energy into
the grid.
The inverter repeats its
start-up routine.
*)
302
Overcurrent (DC) or battery not
detected
303 DC module overtemperature
(PV)
Short-term interruption
while feeding energy into
the grid.
The inverter repeats its
startup routine. Purge cooling air
openings and heat
sink; **)
304 AC module overtemperature
305 No power being fed in, despite
closed relays
Short-term interruption
while feeding energy into
the grid.
The inverter repeats its
startup routine.
**)
306
There is not enough PV power
available for feeding energy into
the grid and no power has been
requested from the battery.
Short-term interruption
while feeding energy into
the grid.
The inverter repeats its
startup routine.
Wait for sufficient
insolation; wait for
an energy manage-
ment command;
**)
307
DC low
DC input voltage too low for
feeding energy into the grid
Short-term interruption
while feeding energy into
the grid.
The inverter repeats its
startup routine.
Wait for sufficient
insolation;
**)
IMPORTANT! Due to the low level of insolation early in the morning and in the evening, the status
codes 306 (Power low) and 307 (DC low) are displayed routinely at these times of day. These status
codes do not indicate any kind of fault.
308
Intermediate circuit voltage too
high
Short-term interruption
while feeding energy into
the grid.
The inverter repeats its
startup routine.
**)
309 PV input voltage too high
