3504 Insulation monitoring device has
detected an insulation error. Since
the parameter IsoErrIgn is set to
On, this error is ignored.
W W ‒ • Check PV array for ground
faults.
3507 Ground fault has occurred on
ungrounded pole of PV array.
Q Q ‒
3510 The Sunny Central has found an
insulation error on the inverter
bridge.
Q Q ‒
3511 The Sunny Central has found an
insulation error.
W W ‒
3512 The Remote GFDI has detected a
permanent ground fault.
Q Q ‒
3515 A ground fault detected by Soft
Grounding has been ignored.
W W ‒
3601 Leakage current to ground is
present in the PV array, or the
threshold defined in parameter
RisoCtlWarn has been reached.
W W ‒ • Check grounding and
equipotential bonding.
• Check module wiring and
PV system design.
• Check the RisoCtlWarn
parameter.
3803 Current of PV array is too high. 1 min D x • Check DC input current.
• Check module wiring and
PV system design.
4000 String-failure detection has detected
a defective string. Error number
appears on display only.
W W • Read off the number of the
defective string in the
instantaneous value
SSMUWrnCode.
4003 Reverse currents detected in the
PV array, or DC terminal
reverse-poled.
30 s Q ‒ • Check PV modules for short
circuits.
• Check module wiring and
PV system design.
• Check DC terminals for correct
polarity.
• Check the functionality of the
entire string.
4004 String-current monitoring has
detected a defective string.
W W - • Check the functionality of the
entire string.
