ID problem with hardware
The inverter will automati-
cally attempt to connect
again and, if possible, re-
sume feeding energy into
the grid
Update inverter firm-
ware; *)

Possible hardware defect
431
Software problem
Inverter does not feed ener-
gy into the grid.
Carry out AC reset
(switch automatic circuit
breaker off and on); up-
date inverter firmware; *)
436
Function incompatibility (one or more PC
boards in the inverter are not compatible
with each other, e.g., after PC board re-
placement)
The inverter will automati-
cally attempt to connect
again and, if possible, re-
sume feeding energy into
the grid
Update inverter firm-
ware; *)
437
Power module problem
438
Function incompatibility (one or more PC
boards in the inverter are not compatible
with each other, e.g., after PC board re-
placement)
The inverter will automati-
cally attempt to connect
again and, if possible, re-
sume feeding energy into
the grid
Update inverter firm-
ware; *)
443
Intermediate circuit voltage too low or
unsymmetrical
Inverter does not feed ener-
gy into the grid.

-
Compatibility error (e.g., due to a PC
board replacement)
-
Invalid power module configuration
Inverter does not feed ener-
gy into the grid.
Update inverter firm-
ware; *)
447
Insulation fault
Inverter does not feed ener-
gy into the grid.

450
No guard found
451
Memory error detected
The inverter will automati-
cally attempt to connect
again and, if possible, re-
sume feeding energy into
the grid

452
Communication error between proces-
sors
453
Grid voltage and power module do not
match
454
Grid frequency and power module do not
match
456
Anti-islanding function has stopped run-
ning properly
457
Grid relay stuck or neutral conductor
ground voltage too high
Inverter does not feed ener-
gy into the grid.
Check grounding (volt-
age of neutral conductor
ground must be under
30 V); *)
