FAULTS & ERRORS
Problem Possible Cause Solution
Low battery voltage Input battery voltage is
below 10.5V (12V), 21V (24V)
a) Recharge battery
b) Battery may be too small.
Refer to pg 16 for recommended
battery sizes
c) Check cable connections and that
cable sizes are sufficient (see pg 6)
Low battery Shutdown a) The input battery voltage
is below 10V (12V),
19.5V (24V)
b) There is a voltage drop
between the battery and
the inverter
a) Recharge battery immediately.
Failure to do so may cause
permanent battery damage
b) Check cable connections and
that cable sizes are sufficient
(see pg 6)
Over temperature
shutdown
Internal temperature is

Turn off inverter and allow to cool
Overload shutdown The inverter is overloaded:
a) there are too many
appliances running, or
b) the appliance is not
suitable for this inverter
Turn off inverter to reset.
Check the (combined) power usage
of the appliance/s is suitable for this
inverter
High battery shutdown Input battery voltage is
above 15.5V (12V) or
31.0V (24V)
a) Confirm input battery is correct.
b) Check that a battery charger
is not connected to the battery
Output short circuit Appliance may have an
electrical fault
Remove appliance and have it
