Fault Type Cause
Automatic DC under-voltage
shutdown (immediate)
occurs if DC voltage is
below 16 Vdc (24 V) or
32 Vdc (48 V)
The fault clears and the
inverter restarts when
DC voltage reaches
23 Vdc (24 V) or 46 Vdc
(48 V).
Automatic DC under-voltage
shutdown occurs if DC
voltage is below 20 Vdc
(24 V) or 44 Vdc (48 V).
Automatic DC over-voltage
shutdown. Occurs if DC
voltage is above 32 Vdc
(24 V) or 70 Vdc (48 V).

Faults and Warnings
Solution
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
29 Vdc (24 V) or 58 Vdc (48 V) at
XW Inverter/Charger terminals.
Check all other charging source
outputs, battery cables. Ensure your
DC source is regulated below your
high battery cut out or increase your
Hi Batt Cut Out setting.
No action. Clear fault and resume
operating or configuring the unit. If
the fault persists, have the unit
serviced.
