circulation around the unit. Do not place items on or over the inverter during
operation. A fan is helpful if the inverter is operating at maximum power outputs for
extended periods of time. The unit will shut down if the internal temperature exceeds
operating temperatures. The unit will restart after it cools.
CAUTION - DO NOT USE THE INVERTER NEAR FLAMMABLE MATERIALS OR IN
ANY LOCATIONS THAT MAY ACCUMULATE FLAMMABLE FUMES OR GASES.
5. OPERATING TIPS
5.1 RATED VERSUS ACTUAL CURRENT DRAW OF EQUIPMENT
Most electrical tools, appliances and audio/video equipment have labels that indicate
the power consumption in amps or watts. Be sure that the power consumption of the
item you wish to operate is rated at 750 watts or less (If the power consumption is
rated in amps AC, simply multiply by the AC volts (120) to determine the wattage).
The inverter has overload protection, so it is safe to try to operate equipment rated at
750 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 Husky
Power Inverter to run. However, larger resistive loads, such as electric stoves or
heaters, usually require more wattage than the Husky Power Inverter can deliver on a
continuous basis. Inductive loads, such as TV’s and stereos, require more current to
operate than do resistive loads of the same wattage rating. Induction motors, as well
as some televisions, may require 2 to 6 times their wattage rating to start up.
The most demanding in this category are those that start under load, such as
compressors and pumps. Testing is the only definitive way to determine whether a
specific load can be started and how long it can run. The unit will simply shut down if
it is overloaded. To restart the unit after a shutdown due to overloading, remove the
overload.
CAUTION: This inverter will not operate high wattage appliances or equipment that
produce heat, such as hair dryers, microwave ovens, and toasters.
5.2 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,
Husky recommends that the operator start the vehicle every half hour to recharge the
battery system. This will guard against any unexpected shut-down of the equipment
and will ensure that there is always sufficient battery capacity to start the vehicle’s
engine. The inverter will sound it’s alarm when DC voltage drops to 10.5V.
The inverter may be used whether or not the vehicle’s engine is running. However, the
inverter may not operate while the engine is starting since the battery voltage can drop
substantially during cranking.
The inverter draws less than 0.3 ampere from the battery when it is not supplying
power to a load and switch is in ON position. In most instances, the inverter can be
left connected to the battery when not in use since it draws so little current. However,
if the vehicle is to remain unused for several days, disconnect the inverter from the
battery.
6. PROTECTIVE FEATURES OF THE INVERTER
Your Husky Power 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 alarm will sound when input voltage drops to 10.5 Volts. The
Husky Power Inverter automatically shuts down when input voltage drops to 10 volts.
