Fault Type Cause
Automatic Battery over- temperature
shutdown at 60 °C.
Automatic Capacitor over-
temperature shutdown at
105 °C.
Manual Controller fault
DC under-voltage
shutdown (immediate)
occurs if DC voltage is
below 32 V. The fault
clears and the inverter
restarts when DC voltage
reaches V+4 V.
DC under-voltage
shutdown occurs if DC
voltage is below voltage
level.
Escalating DC over-voltage
Auto Fault. shutdown. Occurs if DC
voltage goes over the
High Batt Cut Out
setting.
The fault can also occur
when batteries are
disconnected at the DC
breaker while the Conext
XW+ is operating.
Solution
Clear the fault and attempt
restart. Stop charging, check
battery voltage and
temperature. Check for
excessive ambient
temperature and adequate
ventilation in the battery
compartment.
Note: Shutdown temperature
is above 60 °C. Recovery
occurs at 50 °C where the XW
will be enabled again.
Clear the fault and attempt
restart. Ensure adequate
ventilation around the Conext
XW+. Reduce AC loads.
Service required.
Check for the correct battery
voltage at the inverter's DC
input terminals. Check for an
external DC load on the
batteries. Check condition of
batteries and recharge if
possible.
See F47.
Clear the fault and attempt
restart. Ensure battery
voltage is below 58 VDC at
Conext XW+ terminals.
Check all other charging
source outputs, battery
cables. Ensure that batteries
are connected, or that your
DC source is regulated below
your high battery cut out or
increase your Hi Batt Cut
Out setting.
