designed to shut down automatically in the event of a
power overload. Testing appliances and equipment with
s t a rt up load ratings comparable to your inverter wattage
rating will not damage it.
If a piece of equipment or an appliance will not operate, first
c o n f i rm that the inverter has been properly connected to
the 12 volt power source (See "Making The Connection"). If
all connections have been properly made, turn the invert e r
rocker switch ON (l), OFF (O) and ON (l) again in quick suc-
cession. If this pro c e d u re is unsuccessful, it is likely that the
i n v e rter does not have the re q u i red start up capacity or your
b a t t e ry supply isn’t large enough to operate the equipment
or appliance in question.
Selecting the Optimum Power Sourc e .
Operating the inverter for extended periods combined with
a high continuous load demand may result in excessive
power drain from the battery. There f o re, the re s e rve
capacity of the battery you select to power the inverter is an
i m p o rtant consideration.
The potential power drain can be estimated by calculating
the re s e rve power ("amp/hour") of the battery and the
amps re q u i red by the inverter to meet the continuous load
demand of the equipment or appliance being operated.

Don’t Push It.
Although your Whistler power inverter has the capacity to
p rovide power output (excess current) equal to appro x i-
mately two times its rated wattage capacity for a very brief
period, it is designed to operate equipment and appliances
with start up load wattage ratings no higher than its own
maximum continuous wattage rating.
For example, the 1500 model has a maximum continuous
rating of 1500 watts. Although this model has the capacity
to briefly provide up to 3000 watts of power (that is, excess
c u rrent), it is designed to operate equipment and appli-
ances with start up load re q u i rements of 1500 watts or less.
C o n s e q u e n t l y, if the start up load rating of your equipment
or appliance is the same or approximately the same as the
maximum continuous rating of the invert e r, the inverter will
attempt to start loads above the continuous rating.
Some refrigerators, freezers, pumps and other similar
equipment and appliances re q u i re very high start up loads
to operate. Before attempting to power up this type of
equipment or appliance, make especially certain that all
connections have been properly made and that the power
s o u rce is fully charg e d .
To determine whether your inverter will operate a part i c u l a r
piece of equipment or appliance, run a test. The inverter is
