Introduction
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 dif
fi
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).
