This manual is for use by qualified personnel only
0012 AC Voltage Low S
This fault indicates that the utility
grid voltage is below or fell below
the setting of Min AC Volt%: of
nominal Vac for greater than 6
cycles. Xantrex inverter units with
the low voltage ride-through option
are able to continue to supply
current through the fault for 1600
ms as long as the voltage does not
drop below 5% of nominal Vac.
This fault is auto-clearing. Once
the utility grid voltage has
recovered within the acceptable
operating range, the Xantrex
inverter qualifies the value and
automatically clears this fault and
resumes normal operation after a 5
minute delay period.
• Utility grid voltage
fell below the
allowable limit
• P1001 on control unit
is loose or
disconnected
0013 AC Voltage High S
This fault indicates that the utility
grid voltage is above or rose above
the setting of Max AC Volt%: of
nominal Vac for greater than
6 cycles. This fault is auto-clearing.
Once the utility grid voltage has
recovered within the acceptable
operating range, the
Xantrex
inverter
qualifies the value and
automatically clears this fault and
resumes normal operation after 5
minute delay period.
• Utility grid voltage
rose above the
allowable limit
0015 Grid
Disconnection
S
This fault indicates that the Xantrex
inverter has detected a sudden AC
voltage increase of greater than
40% of the nominal peak-to-peak
value. This normally is the result of
a sudden disconnection from the
Utility grid while the Xantrex
inverter was processing power.
• -Q1 was opened
while the Xantrex
inverter was
processing power or
an upstream
disconnect was
opened
0016 DC Disconnect
Switch
S
This fault indicates that upon
entering the Power Tracking State,
the Xantrex inverter has detected
that the DC disconnect switch is in
the wrong state.
• -Q11 is inoperable
• -K31 is inoperable
