INVERTER BASICS
Getting Started
Power equipment and appliances which operate with motors
or tubes require an initial surge of power to get them up and
running. This power surge is referred to as the "starting load"
or "peak load." (By comparison, electrical devices such as
standard light bulbs do not require a large starting load).
Once the equipment or appliance has been powered up, it
settles down to a slower pace and requires far less electrical
power to operate. This lower power requirement is referred
to as the "continuous load."
In order to ensure that the capacity of your WHISTLER
inverter is sufficient to meet the required start up load, you
must first determine the power consumption of the
equipment or appliance you plan to operate.
Power consumption is rated either in wattage or amperes,
and information regarding the required "watts" or "amps"
generally is stamped or printed on most appliances and
equipment. If this information is not indicated on the
appliance or equipment, check the owner’s manual. Contact
the appliance or equipment manufacturer to determine
if the device you are using (TV’s, battery charger,
computer, medical equipment, etc.) is compatible with a
modified sine wave.
If the power consumption is rated in amps, multiply the
number of amps by 110 (AC voltage) to determine the
comparable wattage rating. Induction motors, as well as
some televisions, may require 2 to 6 times their wattage
rating for startup.
For further information on the fundamental operating
principles of WHISTLER inverters and related technical
data, see "Technical Operating Principles."

IMPORTANT INFORMATION
Important Information About Your New WHISTLER
Inverter.
This manual will provide you with directions for the safe
and efficient operation of your WHISTLER inverter. Read
the manual carefully before using your new WHISTLER
inverter and keep the manual on file for future reference.
Notes:
Your WHISTLER inverter is designed to operate from a 12
volt power source only. Never attempt to connect your
Whistler inverter to any other power source, including any
AC power source.
• The length of the supplied cables is matched for the
current needed by the inverter. Making this cable longer
will make the inverter less efficient and may cause the
cables to heat up.
• Do not attempt to lengthen the supplied power cables.
• 110 volts can be lethal. Improper use of your WHISTLER
inverter may result in property damage, personal injury or
loss of life.
• Do not connect the inverter’s output to any other power
source.
• Not recommended for use with medical equipment.
Check with the appliance manufacturer for compatibility
with modified sine wave inverters. Some appliances may
not work well, not at all or be damaged. For more
information on compatibility issues, please visit our inverter
FAQ page.
