0017 Phase Error S The calculated frequency is
negative indicating the phase
rotation of the grid is incorrect.
The correct rotation is L1, L2, L3
Phase Rotation of the
incoming grid
connections is wrong.
0018 AC Contactor
Circuit Fault
S Xantrex GT500 E GI and Xantrex
GT630 E GI only: An Auxiliary
contact is used to determine the
state of -K1. This fault indicates
the Xantrex GT500 E GI and
Xantrex GT630 E GI has
detected the contactor is not in
the correct state.
-K1 or -K33 is
inoperable
0019 PV Over-I Positive H This fault indicates that the
Xantrex inverter has detected a
DC current in the Positive
connection to the Unit greater
than the maximum allowed of
1300 amps
• -T13 is inoperable
• P3 on control unit is
loose or
disconnected
• PV system wiring
short
0020 PV Over-I Negative H This fault indicates that the
Xantrex inverter has detected a
DC current in the negative
connection to the Unit greater
than the maximum allowed of
1300 amps.
• -T14 is inoperable
• P3 on control unit is
loose or
disconnected
• PV system wiring
short
0021 PV Over-Voltage S This fault indicates that the
Xantrex inverter has detected a
DC input voltage of greater than
the maximum allowed value of
1100 Vdc.
• PV system mis-
wiring
• Lightning strike on
PV system wiring
0023 Bus Voltage High H This fault indicates that the
Xantrex inverter has detected
that the DC bus voltage has
exceeded the maximum allowed
value of 1020 Vdc.
• PV system mis-
wiring
• Lightning strike on
PV system wiring
