This manual is for use by qualified personnel only
XX30 Matrix Over-
Current
H
This fault indicates that the Xantrex
inverter has detected that the AC
current on one or more phases of
the inverter output has exceeded
the maximum allowed value of
2000A
pk
.
The first two digits of the fault code
indicate the particular phase
where the over-current occurred
as follow:
• 0130 - Matrix over-current in
phase A
• 0230 - Matrix over-current in
phase B
• 0430 - Matrix over-current in
phase C
If more than one phase faults
simultaneously, the two first digits
are added in hexadecimal form to
indicate an over-current condition
in more than one phase, thus the
error code contains the summation
of the faulted phases.
• P3 on control unit is
loose or
disconnected
• AC system wiring
short
0033 Ground Over-
Current
S
This fault indicates that the Xantrex
inverter has detected that the
ground fault current has exceeded
the setting of Max Gnd Flt I:.
• P3 on control unit is
loose or
disconnected
• Fault between
ground and live
parts of the AC or
DC system
XX34 Unused Matrix
Over-I
H
This fault indicates that the inverter
has detected a control unit board
failure.
This indicates a
problem on the control
unit board.
0035 Fault Class 35 S
The Bender relay has detected the
impedance between ground and
the PV array has dropped below
the setting of the Bender relay.
Alternatively the enclosure
temperature is too low and
humidity is too high.
• Damaged insulation
between the array and
ground, or inadvertent
grounding of the array
or excessive moisture
on the array.
• Cabinet temperature
or cabinet humidity is
outside allowable
range.
