< High leakage current >
The leakage current of the Sunny Boy and
the PV generator is too high.
This can be caused by a sudden fault in the
connection to ground, a fault current or a
malfunction.
The Sunny Boy immediately stops feeding
the mains system as soon as the limit has
been reached and then automatically
resumes normal operation when the fault is
no longer present.
•
Check the strings for ground faults,
as described in section 12.1
„Ground Fault Monitoring” (Page
67).
•
Have the PV generator installation
engineer fix the ground fault before
you can reconnect the string in
question.

< Leakage current too high >
•
Check the strings for ground faults,
as described in section 12.1
„Ground Fault Monitoring” (Page
67).
•
Have the PV generator installation
engineer fix the ground fault before
you can reconnect the string in
question.
38
< DC overcurrent >
Overcurrent occurs on the DC side of the
Sunny Boy and the Sunny Boy switches off.
If the event occurs frequently:
•
Check the design and connection
of the PV generator.
39
< Waiting for DC start conditions >
The input power or voltage of the PV
modules is not yet sufficient for feeding into
the grid.
•
Wait for greater radiation.
•
If this occurs again at medium
radiation, check the PV system
design or correct connection of the
PV generator.

Contact SMA Technical Service
Line (see section 14 „Contact”
(Page 72)).
65
< Overtemperature >
Sunny Boy deactivates due to excessive
temperature.
•
Ensure ventilation is sufficient.
•
Check heat dissipation as
described in 9.1 „Checking Heat
Dissipation” (Page 53).
