What Appliances run from a Modifi ed Sine Inverter
Today’s inverters come in two basic output waveforms: modi
fi
ed sine (which
is actually a modi
fi
ed square wave) and pure sine wave. Modi
fi
ed sine wave
inverters approximate a pure sine waveform.
The output of a modi
fi
ed sine wave inverter will run most electronic and
household items—including but not limited to TV, VCR, satellite dish receiver,
computers, and printers. Some devices such as rechargeable power supplies
for phones, drills, and other like devices may not run or be damaged by
modi
fi
ed sine wave inverters.

Appliances and Run Time
The MM Series inverter can power a wide range of household appliances
including small motors, 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.
Depending on your inverter capacity, larger electrical appliances such as coffee
pots and hair dryers can be used for short durations. However, loads that are
used for longer periods such as stoves or water heaters can quickly drain your
batteries and are not recommended for inverter applications. 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 MM Series inverter has a built-in safeguard that automatically protects
your batteries from being over-discharged.

Standard Features and Benefi ts
The MM Series inverter
converts 12 volts direct current (VDC) power from
your battery to 120 volts alternating current (VAC) power.
On models with the
multi-stage battery charger feature, the incoming AC power is optimized using
Power Factor Correction (PFC) technology to keep the inverter’s battery bank
fully charged. This inverter’s die-cast aluminum baseplate ensures maximum
durability and a cooler, more ef
fi
cient operation. The inverter is equipped with
the following features:
•
600 or 1200 watts continuous (depending on model) at 25°C (77°F)
•
Numerous protection features to ensure safe operation
•
AC transfer switch circuitry; allowing incoming AC power to continue to
pass through to power loads even if the inverter is off
•
Dead battery charging (MM1212 & MM1212-G models) for batteries that
are extremely low
•
Automatic 4-stage battery charger with power factor correction and
temperature compensation—for optimum battery charging (models with
battery charger and using the Battery Temperature Sensor)
•
True RMS output voltage regulation to ensure the inverter will deliver
the correct amount of power—within the DC input voltage range and the
continuous output power level
•
Quick connection accessory and remote ports—easily accepts several
optional remote controls and the Battery Temperature Sensor
