Inverter Basics

Don’t Push It.

Although your Whistler 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 800 model has a maximum continuous rat- ing of 800 watts. Although this model has the capacity to briefly provide up to 1600 watts of power (that is, excess cur- rent), it is designed to operate equipment and appliances with start up load requirements of 800 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 for up to 10 seconds.

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 start up load ratings comparable to your inverter wattage rating will not damage it.

INVERTER BASICS

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 suc- cession. If this procedure is unsuccessful, it is likely that the inverter does not have the required start up capacity to operate the equipment or appliance in question.

Note:

•Most heat generating appliances require start up loads in excess of 1000 watts and the inverter will not operate such appliances as coffee makers, irons, hair dryers or heaters.
