3.7 Error Display
Your Solar Inverter works fully automatically.
Should external or internal factors neverthe-
less lead to an error, an error number will be
flagged on the display. Below, you will find
a description of the error for each error
number. If three consecutive error numbers
are listed in the description, each of them
refers to an energy unit of the Solar Inverter.
E. g. for the description of errors 004 to 006,
this means:
· Error 004 refers to:
DC inlet 1 (left DC connection)
energy unit 1 (lower control circuit board)
grid phase L1
· Error 005 refers to:
DC inlet 2 (middle DC connection)
energy unit 2 (middle control circuit board)
grid phase L2
· Error 006 refers to:
DC inlet 3 (right DC connection)
energy unit 3 (upper control circuit board)
grid phase L3
Errors 001 to 003
· DC overvoltage
A maximum PV generator no-load voltage
of 850 V is admissible. All components of
the DC inlet have a sufficient safety factor. If
this limit is exceeded, the Solar Inverter will
stop the injection, and «error 001» will be
flagged, for example. That means an over-
voltage of the PV generator on inlet 1 or on
the lower energy unit.
Errors 004 to 006
· Frequency fault
The Solar Inverter continuously monitors
the applied grid frequency. Should it be
outside the range specified in E DIN VDE
0126-1-1, the Solar Inverter will stop the
injection, and «error 004» will be flagged,
for example. That means a grid frequency
error on grid phase L1 or on the lower
energy unit.
