SAFETY OPERATION MAINTENANCESETUP

AC Appliance Compatibility

The Power Pack has two Outlets for AC appliances.

The total load from both outlets must not exceed the

AC Outlet power listed in the Specifications Chart.

Some appliances may have a high initial surge which may

make them incompatible with this unit. Calculate the total

wattage needed to start up the appliances, and the total

wattage needed to run the appliances before operation.

Figure D

To calculate the size of the load you plan to use

with the Power Pack, use the following formula:

Amps x Volts = Watts

For example, if you have two appliances whose

running amps total 1.5 amps, you will need 180 watts

of power (1.5 amps x 120V = 180 Watts) to run the

items continuously. This figure is within the capacity

of the unit per “Continuous”. (See Figure D.)

However, if the peak power for the items is 4 amps (4

amps x 120V = 480 Watts), then the appliances are not

suited to this unit. They will draw too much power for

the unit to start the items per “Peak”. (See Figure D.)

Always calculate the power needed to start up

the appliances and to run them before attempting

to use the Power Pack for AC appliances.

The following chart shows the estimated

power to run some common appliances.

Note: Use this chart as a guideline only.

The actual power usage may vary based on the model

or brand of the appliance. Check the actual wattage

of your appliances and calculate the amount of power

needed to start and run them. (See Figure E.)

Figure E

The wattage rating of AC appliances is the average

amount of power used by the unit. Items such as

computer monitors, televisions and appliances with

motors draw more power when they are first turned on

than the amount of power that they use continuously.

The Power Pack supports a startup surge of up to

600 W, but some appliances exceed this level and

will trigger the Inverter’s power overload shut off

feature, and cannot be used with this Inverter.
