Trouble Shooting
AC appliances do not work, and the green power indicator does not light.
CAUSES SOLUTION
Bad battery
Revers connection of
negative and positive
poles
Untight connection of cables
Check the battery, replace it if
necessary
co
rrect the connection to battery,
the inverter may be damaged.
Replace the fuse inside inverter
(outside warranty cover)
Check the cables and the
connection, screw tight the
wiring terminal

Overload shut off due to
overhigh peak power despite of
power of electric appliances
lower than the inverter′s r ated
power
CAUSES SOLUTION
Use appliances having
power below the inverter′s
rated power
Overload shut off due to rated
power of appliances exceeding
the inverter′s rated power
Since the peak power of the
electric appliances exceeds
the peak power of the
inverter, use an appliance
with a peak power consistant
with the inverter
Trouble Shooting
The electric appliances does not work,and the red FAULT indicator of the inverter lights.

Trouble Shooting
CAUSES SOLUTION
The battery is over discharged
(inverter gives an alarm)
Over temperature shut off due
to bad ventilation
Too large input current
Replace the battery or use
battery charger to charge your
battery
Switch off the inverter and let it
get cooled for 15 minutes. Clear
objectes around the fan and the
inverter. Place the inverter at a
cool place.Reduce load
according to requirements.
Restart
Check the working state of the
charging system. Make sure the
output voltage of the battery is
within the proper voltage
Trouble Shooting
The measured output courrent of the inverter is too low
CAUSES
Too low current of the inverter
SOLUTION
Measure“modified sine wave
”
with a“ real effective value
multimeter” to get the accurate
data
The range of reading of
common ammeter is too small
Charge the battery or
change battery
