engine is being turned over as battery voltage drops
substantially whilst the engine is being started.
In most cases the inverter can be left connected to the
battery when not in use as it draws very little current,
however if the vehicle is to remain unused for several days
disconnect the inverter from the battery.
In built protection.
Your inverter monitors the following potentially hazardous
conditions:
•
Low battery voltage:
This condition is not harmful to the
inverter but could damage the power source. An audible
signal will sound when input voltage drops to 10.5V. The
inverter automatically shuts down when input voltage drops
to 10.0V. When the power source input voltage is above
10.5V the inverter may be restarted.
•
Over voltage protection:
The inverter will automatically
shut down when the input voltage exceeds 15V DC
•
Short circuit protection:
The inverter will shut down.
Remove the short circuit and the inverter will reset.
•
Overload protection:
The inverter will automatically shut
down when the continuous draw exceeds 15V DC.
•
Overheating protection:
When the temperature sensor
inside the inverter reaches 65 degrees C, the unit will
automatically shut down. In this instance, allow at least 15
minutes before attempting to restart the inverter and always
disconnect appliances.
•
Low battery alarm:
The alarm will sound if the input voltage
drops below 10.5 V, this is an indication that the battery
needs to be recharged. Users should discontinue operation
of the appliance(s) at this point, as the inverter will shut
down shortly after the alarm sounds. The vehicle engine
should be started to recharge the battery. If the low battery
alarm sounds when the battery is fully charged follow the
steps for solving lack of output power in the troubleshooting
guide.
The alarm will sound if the inverter is overloaded,
overheated or if there is an excessive voltage drop
between the battery and inverter.
NOTE:
It is normal for the alarm to sound while the unit is being
connected to, or disconnected from the power source, this is
not indicative of a problem.
FUSE REPLACEMENT
If the external fuse blows (or breakers trip), then there is a
short circuit or overload in the DC wiring. Find and rectify the
problem before replacing the fuse (or resetting the breaker)
and reconnect the inverter.

interference
• DC input below 10 Volts
• Excessive appliance
load-thermal shutdown
• Recharge or replace
battery
• Reduce load-wait for
inverter to cool. Turn off,
then turn on.
• Inverter is cold
• Inverter fuses open
• Bad connection or wiring
• Low battery voltage
• Excessive start up load
• Purely inductive load
• Snow in picture, buzz in
speaker
• Keep inverter and
antenna distant from each
other. Use shielded
antenna cable. Connect
antenna to amplifier
• Make the load not purely
inductive. Operate an
incandescent lamp at
same time as motor
• If appliance does not
start, then appliance is
drawing excessive
wattage and will not work
with inverter
• Recharge battery.
Remove load from inverter
while recharging battery
• Tighten all DC
connections
• Disconnect load from
inverter. Operate inverter
without load for a few
minutes. Reconnect load.
• Open fuse caps in back
of inverter. Remove fuses
and replace with same
type and rating
