1.4 Appliances and Run Time

The MS 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, however, such as

stoves, water heaters, etc., can quickly drain your batteries and are not recommended for this

application.

All electrical appliances are rated by the amount of power they consume. 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 Series inverter has a built-in safeguard that automatically

protects your batteries from over discharge.

Info: For optimum performance, a minimum battery bank of 200 AH is recommended

for moderate loads (<1000W) and greater than 400 AH for heavy loads (≥1000W).
