Inverter Basics

Don’t Push It.

Although your WHISTLER inverter has the capacity to pro- vide 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 maxi- mum continuous wattage rating.

For example, the 400 watt model has a maximum continu- ous rating of 400 watts. Although this model has the capac- ity to briefly provide higher watts of power (that is, excess current), it is designed to operate equipment and appli- ances with start up load requirements of 400 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.

The inverter is designed to shut down automatically in the event of a power overload. Testing appliances and equip- ment with start up load ratings comparable to your inverter wattage rating will not damage it. However, make sure the appliance you are testing is compatible with modified sine wave inverters. See page 4 for more information.

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 this inverter will not operate such appliances as coffee makers, irons, hair dryers or heaters.
