C-1 Appliance Power Consumption

The MS-PAE Series inverter/charger can power a wide range of household appliances including small

motors, hair dryers, clocks, and other electrical devices. As with any appliance using batteries for

power, there is a certain length of time that it can run—this is called “run time.” Actual run time

depends on several variables, including the size and the type of appliance, the type of batteries

installed in your application, as well as the battery’s capacity and age. Other factors such as the

battery’s state of charge and temperature can also affect the length of time your appliances can run.

Appliances such as TVs, VCRs, stereos, computers, coffee pots, incandescent lights, and toasters

can all be successfully powered by your inverter. Larger electrical appliances (such as stoves,

water heaters, etc.) can quickly drain your batteries and are not recommended.

All electrical appliances are rated by the amount of power they consume (see Table C-1). The

rating is printed on the product’s nameplate label, usually located on its chassis near the AC

power cord. Even though it is difﬁ cult to calculate exactly how long an inverter will run a particular

appliance, the best advice is trial and error. Your MS-PAE Series inverter has a built-in safeguard

that automatically protects your batteries from over-discharge.

to the battery sizing worksheet, only list 1/3 of the total wattage rating of the appliance.
