1.4 Appliances and Run Time
The ME 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 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 (SOC) and temperature can also affect the length of time your appliances
can run.
Appliances such as TVs, VCRs, stereos, computers, and lights can all be successfully powered
by your inverter. Depending on your inverter capacity, electrical appliances that use larger loads
such as coffee pots and hair dryers can be used for short durations. However, loads that are
used for longer periods (stoves, water heaters, etc.) can quickly drain your batteries and are not
recommended for inverter applications.
All electrical appliances are rated by the amount of power they consume (See Table 1-1). 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 ME 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).
