Inverter Operation After Faults
Conext XW Pro operation changes when a fault occurs. How the operation changes
depends on the operating state of the unit when the fault occurred—inverting, charging,
grid or generator support, AC bypass, and so on—and on which fault has occurred.
Faults
State when Faults
Occur
Action After Faults
F1, F2: AC Output Inverting
Unit stops inverting and waits for
nominal AC output voltage level, or
a manual clear from user.
F17 to F22:
Relay Welded
Inverting
Unit stops inverting and waits for
user to clear fault.
F23 to F40:
Anti-Islanding
Grid Support (Peak Load
Shaving or Selling)
Unit moves to AC bypass and
waits for nominal grid conditions to
return for a minimum of five
minutes.
F41, F42: Aux power
supply voltage
Unit has qualified AC
input.
Unit shuts down and waits for
nominal AC output voltage level, or
a manual clear from user.
F44:
Battery Over Temp
F45:
Capacitor Over Temp
Any state.
If inverting, the unit shuts down
and waits for the temperature to
return to nominal value. If in any of
the AC-interactive states (charging,
peak load shaving, sell, gen
support), the unit goes into AC
bypass mode until the temperature
returns to the nominal value. If the
unit is not in AC bypass, it shuts
down until the temperature returns
to nominal value. After these faults
clear, the unit returns to its
previous operating state.
F47 to F49:
DC Under Voltage
and Over Voltage
Unit is inverting or has
qualified AC input and is
preparing to charge.
If inverting, the unit shuts down
and waits for nominal voltage. If
operating with a qualified AC
source, the unit charges if charging
is enabled, or remains in AC
bypass if charging is disabled.
F63 to F65:
AC Overload
Inverting or Grid Support
Unit stops inverting and waits to
qualify AC. Unit waits for user to
manually clear fault.
