start 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 confirm 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 inverter
rocker switch ON (l), OFF (O) and ON (l) again in quick
succession. If this procedure is unsuccessful, it is likely that
the inverter does not have the required start up capacity or
your battery supply isn’t large enough to operate the
equipment or appliance in question.
Selecting the Optimum Power Source.
Operating the inverter for extended periods combined with
a high continuous load demand may result in excessive
power drain from the battery. Therefore, the reserve capacity
of the battery you select to power the inverter is an
important consideration.
The potential power drain can be estimated by calculating
the reserve power ("amp/hour") of the battery and the
amps required by the inverter to meet the continuous load
demand of the equipment or appliance being operated.
INVERTER INFORMATION
Don’t Push It.
Although your Whistler power inverter has the capacity to
provide power output (excess current) equal to approximately
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 1200 model has a maximum continuous
rating of 1200 watts. Although this model has the capacity
to briefly provide up to 2400 watts of power (that is, excess
current), it is designed to operate equipment and appliances
with start up load requirements of 1200 watts or less.
Consequently, 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 inverter, the inverter will
attempt to start loads above the continuous rating.
Some refrigerators, freezers, pumps and other similar
equipment and appliances require 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
source is fully charged.
To determine whether your inverter will operate a particular
piece of equipment or appliance, run a test. The inverter
is designed to shut down automatically in the event of a
power overload. Testing appliances and equipment with
