power overload. Testing appliances and equipment with
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"or Ah) 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 Pro-1200W model has a maximum
continuous rating of 1200 watts. Although this model has
the capacity to briefly provide more than its continuous
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 slightly higher than 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 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
