How Do Power Inverters Work?; Precautions - Schumacher Electric PI-750 Owner's Manual

 Do not place the inverter in direct sunlight. The ideal air
temperature for operation is between 50º and 80ºF.
 Keep the inverter well ventilated in order to properly dis-
perse heat generated while it is in use.
 While in use, make sure there are several inches of clear-
ance around the top and sides of the inverter.
 Do not use the inverter near inflammable materials.
 Do not place the inverter in areas such as battery com-
partments where fumes or gases may accumulate.

How Do Power Inverters Work?

There are two stages involved in transforming 12-volt DC
(or battery) power into 110V AC (household voltage):
STAGe 1: The PI-750 power inverter uses a DC to DC
transformer to increase the 12-volt DC input voltage from
the power source to 145-volts DC.
STAGe 2: The inverter then converts the 145-volts DC
into 110-volts AC (household voltage) using advanced
MOSFET transistors in a full bridge configuration. A "modi-
fied sine wave" waveform is generated by this conversion.
For Your Safety: Precautions to keep in mind before
and while using your power inverter:
 only connect the power inverter to a 12-volt battery.
 only connect the power inverter to a 12-volt battery with
the supplied 12-volt power cords. Make sure the cord
connections to the inverter are tight.
 Do not modify the power cord or plug in any way.
