Grid fault (W/A – E05)
No detection of the grid,
not able to synchronize
with the grid or fault within
the country-settings
- Verify if the AC circuit breaker is ON
and operational
- Measure that the grid voltage is
present at the AC terminals
- Check that the DC switch(es) is ON
and that the DC power is > 7W
- Check that the country settings have
been successfully set in Setup>Grid
Setup
- If country is set to Italy, has the Self-
Test failed. Run test again
GUI fault (W/A – E06)
Display is not responding -
T
urn off the AC side. Wait for 3
seconds and then turn on again. Wait
30 seconds for the GUI to turn on
- If still fault, contact your distributor
High voltage on input side (A
– E07)
DC voltage threshold of 600
V
DC
is exceeded
- Contact system installer
Low voltage on input side (A
– E08)
DC voltage is too low to
operate the inverter
- Fault is cleared automatically when
PV voltage exceeds 230 V
- If the inverter remains in this fault
during daylight, and the V
DC
is >230V,
contact your distributor
Low PV isolation resistance
(W – E09)
PV isolation resistance is
below permitted level
-
T
he grounding setup is configured
incorrect
- Check the jumper for the grounding
setup (Jumper Position for the System
Grounding Setup )
- If the jumper is correct positioned,
contact the supplier
Failure on DC side (W/A –
E10)
Inverter failure on the DC
side
- Failure on the DC side. Other W/A
will be displayed
- If the inverter is in Shutdown, turn off
the AC side and then the DC side.
Wait for 30 seconds, then turn on the
AC side and then the DC side
- If the fault persists, contact your
distributor
Failure on AC side (W/A –
E11)
Inverter failure on the AC
side
- Failure on the AC side. Other W/A
will be displayed
- If the inverter is in Shutdown, turn off
the AC side and then the DC side.
Wait for 30 seconds, then turn on the
AC side and then the DC side
- If the fault persists, contact your
distributor
High inverter temperature
(W/A – E12)
Maximum permissible
internal inverter
temperature is exceeded
- Check that the ambient temperature
is within the specification. Refer to 9.
Technical Data
- Check if the ventilation is sufficient,
the minimum distances are compliant
with those stated in this User Manual
and the inverter is shielded from
direct sunshine
- Clean ventilation area. Refer to User
Guide.
Low inverter temperature
(W/A – E13)
Low internal inverter
temperature
- Contact your distributor
