TROUBLESHOOTING

Cause
Battery is defective
Blown fuse
Lose cable connections
AC products connected are rated
at more than 750W; overload
shutdown has occurred.
AC products are rated less than
750W, but high starting surge
has caused overload shutdown.
The voltage input is too low
(alarm is sounding).
Inverter is overheated due to
poor ventilation and has shut
down.
Low voltage battery
Water entered the unit
Low voltage shutdown or thermal
shutdown has occurred.
Standard "average-reading" AC
voltmeter used to measure output
voltage, resulting in an apparent
reading 5 to 15V too low.
Battery voltage is too low
AC product power consumption
is higher than rated.
Battery is old or properly
defective.
Battery is not being properly
charged.
Power dissipation in DC cables.

Solution
Replace battery
Check and replace fuse
Check the connection to the battery. Tighten
as required.
Reduce load, use a product with power rating
less than 750W.
Use a product with starting surge power
within the inverter's capability (≤1500W).
charge the battery
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.
Charge the battery
Disconnect the inverter and wipe immediately
with a dry cloth, or permanent damage can
occur with liquid ingress.
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.
Inverter's "modified sine wave" output
requires "true RMS" voltmeter for accurate
measurements.
Recharge battery
Use a larger battery to make up for increased
power requirement.
Replace battery
Some chargers are not able to fully recharge
a battery. Make sure you use a powerful
charger.
Use shorter/heavier DC cables
