dealer. If the problem continues after troubleshooting, call your local dealer for assistance.
#53068 Failure
#53068 Possible Cause
#53068 Corrective Action
No power, no
indicator.
Battery is defective.
Replace battery.
Blown fuse.
Check and replace fuse.
Lose cable connections.
Check the connection to the
battery. Tighten as required.
The red LED
indicator illuminates.
AC products connected are
rated at more than 300W;
overload shut-down has
occurred.
Reduce load and use a product
with power rating less than 300W.
AC products are rated less than
300W but high starting surge
has caused overload shut-
down.
Use a product with a starting surge
power within the inverter’s
capability (<600W).
The voltage input is too low
(alarm is sounding).
Charge the battery.
Inverter is overheated due to
poor ventilation and has shut
down.
Unplug inverter from DC socket
and allow to be cooled for 15
minutes. Remove objects covering
unit. Move the inverter to a cooler
place. Reduce load if continuous
operation is required. Restart.
Inverter runs small
loads but not large
ones.
Low voltage battery.
Charge the battery.
Water entered.
Water entered the unit.
Disconnect the inverter and wipe
immediately with a dry cloth or
permanent damage can occur with
liquid ingress.
Alarm is sounding.
Low voltage shutdown or
thermal shut-down has
occurred.
Shorten cables or use heavier
cables. Recharge battery. Allow
unit to cool. Improve air circulation
around unit. Locate unit to a cooler
environment. Reduce load if
continuous operation is required.
Measured inverter
output is too low
Standard “average-reading” AC
voltmeter used to measure
output voltage, resulting in an
apparent reading 5 to 15V too
low.
Inverter’s modified sine wave
output requires “true RMS”
voltmeter for accurate
measurements.
Battery voltage is too low.
Recharge battery.
Battery run time is
less than expected.
AC product power consumption
is higher than rated.
Use a larger battery to make up for
increased power requirement.
