Problem: The AC load will not operate, error code shows on digital
display and alarm is sounding.
Error
Possible Cause
Solution
E01
Low voltage shutdown because
battery is discharged.
Recharge battery.
Shorten cables or use heavier
cables.
E02
Over-voltage shutdown because
of high input voltage.
Verify the charging system is
properly regulated and the battery
is 12 V nominal.
E03
The AC product(s) connected
are rated at more than the
inverter’s continuous power
rating; overload shutdown has
occurred.
Use a product with a power rating
within the inverter’s continuous
power rating (see Table 3).
E04
The inverter has overheated due
to poor ventilation.
Overheating shutdown has
occurred.
Turn inverter off and allow to cool
for 15 minutes. Clear blocked fan
or remove objects covering unit.
Move the inverter to a cooler
place. Reduce load if continuous
operation is required.
E05
The AC products connected
have a surge power that exceeds
the inverter’s surge capability or
the AC products connected are
short-circuited and shutdown
has occurred.
The products exceed the inverter’s
surge capability. Use a product
with a starting surge power within
the inverter’s capability.
Correct the short-circuit condition.
