The advanced surge capacity of the PI-400 power
inverter gives it the means to start most electrical appli-
ances including: Color televisions, TV/VCR combinations,
microwaves, refrigeration units, small air conditioners.
In addition, the PI-400 power inverter consumes less
battery power, therefore runs for a longer time because
it is a state-of-the-art inverter. It runs cooler and is highly
efcient.
Before Using PI-400
When you turn on an appliance or a tool that runs on a
motor, the appliance basically goes through two stages:
1. Start up - requiring an initial surge of power (commonly
known as the "starting load" or "peakload").
2. Continuous operation - power consumption drops
(commonly known as the "continuous load").
Before using your power inverter, you need to calculate
these loads, i.e.:
1. Starting load (at start up).
2. Continuous load (on continuous operation).
The formula for power consumption (measured in either
WATTS (wattage) or AMPS (amperes) is: AMPS x
110 (AC voltage) = WATTS. The wattage (WATTS) or
amperes (AMPS) can normally be found stamped or
printed on most appliances and equipment, or in the
user's manual. Otherwise, contact the manufacturer to
nd out whether the device you are using is compatible
with a modied sine wave.
