TROUBLESHOOTING REFERENCE

SYMPTOM
ON/OFF switch is
switched on, LED does
not light, buzzer is off, no
AC output.
Buzzer sounded once
only when switch on,
power LED on, no AC
output.
Buzzer sounds 2 times
and red light flashes 2
times every 8 seconds
Buzzer sounds 3 times
and red light flashes 3
times every 8 seconds
Buzzer sounds 4 times
and red light flashes 4
times every 8 seconds
Buzzer sounds 5 times
and red light flashes 5
times every 8 seconds
Red light constantly
flashing when switched
on
POSSIBLE CAUSE
There is no DC power from
the input terminals
Polarity of the DC input has
been reverse connected
1. Loose AC output
connections.
2. Short circuit on AC output
load.
Voltage across the DC input
terminals dropped below
10.8±0.2Vdc (on 12V input
inverter), 21.6±0.4Vdc (on
24V input inverter).
Voltage across the DC input
terminals dropped below
critical range 10.2±0.2Vdc (on
12V input inverter),
20.4±0.4Vdc (on 24V input
inverter).
Input DC power is higher than
inverter's maximum limit
15.5±0.2Vdc (on 12V input
inverter),
31±0.4Vdc (on 24V input
version)
System overheating, inner
temperature has reached 75°C
The load is higher than the
inverter's rated continuous
power
SOLUTIONS
1. Check the continuity of the DC power input, ensure all
batteries are working or DC power supply is on.
2. Check that the battery inline fuse is intact. Replace if
blown.
3. Check that all connections in the power bank battery
array are tight.
Correct the polarity of the input connections, check and
replace any blown up fuses. If unit remain unresponsive,
permanent damage may have occurred, please contact
technical repair.
1. Ensure fully plugged in on AC output sockets.
2. Ensure connected load is not faulty.
Contact technician/retailer is problem unsolved.
1. Check battery level, if it is low please recharge before
continuing use.
2. On the battery cables used check the cross-section
area of the conductor is no thinner than recommended,
use thicker cables if required. Also avoid connecting
inverter to input power at a long distance as voltage
drops along the length of the cable.
3. Ensure input connections are tight.

2. On the battery cables used check the cross-section
area of the conductor is no thinner than recommended,

inverter to input power at a long distance as voltage
drops along the length of the cable.
3. Ensure input connections are tight.
1. Check and ensure the DC input voltage across the
input terminal is no more than 15/30Vdc.
2. Ensure that the maximum charging voltage of the
battery charger /alternator / solar charge controller is no
more than 15/30Vdc
3. Ensure that an un-regulated DC power supply and
charger are not used to charge the power bank while in
use.
1. Switch off for 15 min to cool down the unit before
switch back on. Check that the fan is working. If not, the
fan/fan control circuit may be defective, please contact
retailer.
2. If the fan works, ensure that the ventilation slots on
the front and back of the inverter are not obstructed
3. If the fan is working and ventilation ports are not
obstructed, check that enough air space is available for
ventilation and cooling. Also check that the air
temperature is less than 45ºC which is the maximum limit
for the inverter to work in.
4. Reduce the load to reduce the heat output.
5. If inverter is under full load, an external fan will help to
cool down the unit.
The appliance requires an inverter with a higher rated
power to start up
