35 < Insulation resist. >
< Check generator >
The inverter has detected a ground fault in
the PV generator. However, the inverter
continues feeding into the grid.
• Check the strings for ground faults, as
described in section 11.1”Checking
the PV Generator for a Ground
Fault” (page74).
• The installer of the PV generator must
remedy the ground faults before you
re-connect the affected string.
< Ground fuse fault >
< Check ground fuse >
The inverter has detected a ground voltage
in the grounding path.
• Check the ground fuse as described
in the in installation guide of the
SMAplug-in Grounding. Check the
strings for ground faults, as described
in section 11.1”Checking the PV
Generator for a Ground Fault”
(page74).
38 < DC overcurrent >
< Check generator >
An overcurrent condition occurs on the
DCside of the inverter and the inverter
switches off.
If this event occurs often:
• Check the layout and the wiring of
the PV generator.
39 < Wait for DC start conditions >
< Start cond. not met >
The input power or the voltage of the
PVmodules is not sufficient for feeding into
the grid.
• Wait for higher irradiation.
• If this event recurs at medium
irradiation, check the PV system
design and correct the connection of
the PV generator.
42 < Wrong earthing type; check earthing
set>
The polarity of the grounding set does not
correspond to the polarity set at the
inverter.
• Check polarity of grounding set.
• Remove grounding set.
• Turn grounding set 180° and
reconnect with correct polarity.
60 - 64 < Self diagnosis >
< Interference device >
• Contact the SMAServiceline (see
section 15”Contact” (page93)).
65 < Self diagnosis >
< Overtemperature >
The inverter switches off due to too high
temperature
• Ensure sufficient ventilation.
• Check heat dissipation, as described
in section 9.1”Checking Heat
Dissipation” (page63).
66 < Self diagnosis >
< Overload >
• Contact the SMAServiceline (see
section 15”Contact” (page93)).
