10.5V+/-0.2V
INVERTER DOES NOT SHUT DOWN
WHEN REMOTE CONTROL

MOTORIZED POWER TOOL
DOES NOT OPERATE AT
CORRECT SPEED
POSSIBLE CAUSE(S)
Shutdown due to high DC input voltage
DC input voltage has risen to High
DC Input Voltage Shutdown
Threshold of 15.2V +/- 0.3V
Buzzer alarm due to intermittent high
AC loads or even at low AC loads
1. DC input wire size is not adequate
for higher capacity loads or there
is loose connection between the
battery and the inverter leading to
DC input voltage falling below the
Low DC Input Voltage Alarm
Threshold of 10.5V +/- 0.2V
2.The battery has developed sulfation
due to undercharging. In this condition,
the internal resistance of the battery
rises above normal and hence causes
abnormal voltage drop on its terminals
at higher discharge current consumed
by higher capacity load
3.The battery is almost discharged
The ON / OFF switch on the
inverter is in ON condition
Excessive start-up current from the
load is activating the Soft Start Circuit
and is reducing the output voltage and
consequently the current to a level
where the starting torque required by
the motor is not sufficient to turn the
motor. (Starting torque in a motor is
proportional to Voltage and the Current)
Purely inductive load with higher
reactive power and lower Power
factor is activating the soft start
circuitry and reducing the output
voltage resulting in reduced speed

SUGGESTED REMEDIES
1. Switch off the AC load and the
inverter.
2. Disconnect the DC input to the
inverter
3. Check the output voltages of the
battery and charging source and
ensure these are below the High
DC Input Voltage Shutdown
Threshold of 15.2V +/- 0.3V
4. Check that a 24V battery is not
being used instead of 12V battery
5. The unit will reset automatically
once the voltage drops to
14.6V +/- 0.2V
6. CAUTION! Voltage input of > 16 V will
permanently damage the inverter
1. Use thicker wires between the
battery and the inverter and tighten
all DC input circuit connections
2. Check internal resistance of the
battery and remove sulfation by
equalizing the battery or replace
the battery
3. Recharge the battery
When using the remote Control ,ensure
that the ON / OFF switch on the inverter
is in OFF position
If appliance does not start, then the
appliance is drawing excessive
power and will not work with the
inverter
Make the load not purely inductive.
operate an incandescent lamp at the
same time as the motor. This will
reduce the reactive power and raise
the Power factor so that the Soft
Start Circuit is not activated
