• Overload protection: The inverter will automatically
shut down when the continuous power consumption
is over the rated Max power output.
• Overheating protection: When the temperature sen-
sor 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 10.5V,this is an indication that
the battery needs to be recharged. Users should dis-
continue 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 re-
charge 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, over-
heated 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.
TROUBLE SHOOTING
No AC output
• Inverter is too hot
• Disconnect load from inverter. Operate inverter with-
out load for a few minutes. Reconnect load.
Motorised power tool won’t start
• Excessive start up load
• If appliance does not start, then appliance is drawing
excessive wattage and will not work with inverter
Motorised power tool does not operate at correct
speed
• purely inductive load
• Make the load not purely inductive. Operate an in-
candescent lamp at same time as motor
Television/Radio interference
• Snow in picture, buzz in speaker
• Keep inverter and antenna distant from each other.
Use shielded antenna cable. Connect antenna to
ampli
fi
er
• Safe: do not position the inverter near any
fl
amma-
ble material or in a position that may accumulate
fl
ammable fumes or gases.
OPERATING TIPS
Rated versus actual current draw.
Most electrical equipment has labels that indicate the
power consumption in amps or watts. Ensure the power
consumption of the item you wish to operate is speci-
fi
ed at the rated watts or less. The inverter has over-
load protection so it is safe to try and operate equip-
ment rated at the speci
fi
ed watts or less. The inverter
will shut down if it is overloaded. The overload must be
removed before the inverter will restart; resistive loads
are the easiest for the inverter to run. However larger
resistive loads, such as, stoves and heaters usually
require more wattage than the inverter can deliver on
a continuous basis. Inductive loads such as, TV’s and
stereos require more current to operate than resistive
loads of the same wattage rating. Induction motors as
well as some televisions may require 2-6 times their
wattage rating to start up. The most demanding in this
category are those that start under load such as, com-
pressors and pumps. Testing is the only de
fi
nitive way
of determining if a speci
fi
c load can be started and how
long it will run. The inverter is
fi
tted with overload pro-
tection so will simply shut down if overloaded. To restart
the unit after overloading remove the overload and if
necessary turn the power switch off and then on.
Battery operating time.
With a typical vehicle battery, a minimum operating time
of 2 to 3 hours can be expected. In most instances, 5
to 10 hours of operating time is achievable however
it is recommended that the operator starts the vehicle
every 2 to 3 hours to recharge the battery system thus
guarding against unexpected equipment shut down
and ensuring that there is still suf
fi
cient power to start
the engine. The inverter’s built in alarm will sound if
the DC voltage drops below 10.5V. The inverter can
be used whether or not the vehicles engine is running
however the inverter will not operate whilst the engine
is being turned over as battery voltage drops substan-
tially 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 hazard-
ous 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 10,5 V. 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 automati-
cally shut down when the input voltage exceeds
15.5V DC
• Short circuit protection: The inverter will shut down.
Remove the short circuit and the inverter will reset.
