3.3 Fault indications
Your solar inverter operates fully automati-
cally and maintenance-free. However,
should malfunctions occur due to external
or internal causes, these will be indicated
in the first line of the display. The available
measured values will be provided in the
second line.
Fault 3
· DC overvoltage
A maximum no-load voltage of 750 V is
permitted for the PV generator. All com-
ponents of the DC input are adequately
dimensioned with a safety factor. If the
threshold is exceeded, the solar inverter
stops the feed-in and a «DC overvoltage
error» is displayed.
Fault 4
· Frequency error
The solar inverter constantly monitors the
grid frequency. If this is outside the range
permitted by DIN V VDE V 0126-1-1,
the solar inverter will stop the feed and
«Fault 4» will be indicated.

Fault 5
· Overheating
Your solar inverter is designed for an
ambient temperature of up to +40°C.
When the maximum upper temperature
threshold is reached, the feed-in is stop-
ped. When the heat sink temperature has
decreased, the solar inverter starts up
again automatically.
Fault 6
· Grid undervoltage, 1-phase
Your solar inverter constantly monitors the
voltage level of the feed-in phase. If the
level falls below the minimum permissible
limit value, the solar inverter stops the
feed and only restarts when the voltage
value rises above the minimum permissible
limit value. If the voltage at L1 falls below
160 V, the solar inverter can no longer be
supplied.
