35 < Insulation resist. >
< Check generator >
The inverter has detected a ground fault in
the PV array. However, the inverter
continues feeding into the grid.
• Check the strings for ground faults as
described in section 11.1"Checking
the PV Array for Ground Faults"
(page72).
• The installer of the PV array 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 installation manual of the
SMA Plug-in Grounding.
• Check the strings for ground faults as
described in section 11.1"Checking
the PV Array for Ground Faults"
(page72).
38 < DC overcurrent >
< Check generator >
The inverter switches off due to an
overcurrent on the DC side.
If this event occurs frequently:
• Check the design and the wiring of
the PV array.
39 < Waiting for DC start conditions >
< Start cond. not met >
The feed‑in power or feed‑in voltage of the
PV modules is insufficient for feeding into
the power distribution grid.
• Wait for more sunlight.
• If this event recurs even when the
amount of sunlight is average, check
the design of your PV plant and make
sure the PV array is wired properly.
42
< Wrong earthing type; check earthing set >
The SMA Plug‑in Grounding polarity does
not correspond to the polarity set in the
inverter.
• Correct the grounding type as
described in the installation manual
for the SMA Plug‑in Grounding.
60 ‑ 64 < Self diagnosis >
< Interference device >
• Contact the SMA Service Line (see
section 15"Contact" (page94)).
65 < Self diagnosis >
< Overtemperature >
The inverter switches off due to too high
temperature
• Ensure sufficient ventilation.
• Check the heat dissipation as
described in section 9.2"Checking
the Heat Dissipation" (page61).
66 < Self diagnosis >
< Overload >
• Contact the SMA Service Line (see
section 15"Contact" (page94)).
67 < Comm. disturbed >
A fault has occurred in the internal
communication of the inverter. However,
the inverter continues feeding into the grid.
If this event occurs frequently:
• Contact the SMA Service Line (see
section 15"Contact" (page94)).
