3401 < DC overvoltage >
< Disconnect generator >
The DC input voltage connected to the
inverter is too high. • Immediately disconnect the
inverter from the PV array, as
described in Section 8
"Disconnecting the Inverter from
Voltage Sources" (page 58). The
inverter may otherwise be
destroyed.
• Check the DC voltage of the strings for
adherence to the maximum input
voltage of the inverter before
reconnecting the inverter to the PV
array.
3501 < Insulation resist. >
< Check generator >
The inverter has detected an earth fault in
the PV array. • Check the strings for earth faults as
described in Section 11.1 "Checking
the PV Array for Earth Faults"
(page 75).
• The installer of the PV array must
remedy the earth faults before you
re-connect the affected string.
3601 < High discharge curr. >
< Check generator >
The leakage current from the inverter and
the PV array is too high.
This can be caused by a sudden earth
fault, a residual current or a device
malfunction.
The inverter interrupts feed-in operation
immediately after exceeding a limiting
value and then automatically re-connects
to the electricity grid. • Check the strings for earth faults as
described in Section 11.1 "Checking
the PV Array for Earth Faults"
(page 75).
• The installer of the PV array must
remedy the earth faults before you
re-connect the affected string.
3701 < Resid.curr.too.high >
< Check generator >
The inverter has detected a residual
current through brief earthing of the
PV array. • Check the strings for earth faults as
described in Section 11.1 "Checking
the PV Array for Earth Faults"
(page 75).
• The installer of the PV array must
remedy the earth faults before you
re-connect the affected string.
