4 DEFINITIONS
4.1
QUASI SINE WAVE:
Quasi Sine Wave is also known as "modified sine wave" or "modified square wave." The inverter AC
output wave shape is rectangular with the amplitude being proportional to battery voltage. The inverter
varies the wave width as needed to maintain 120 volt true RMS output. A true RMS voltmeter is required to
accurately measure the quasi sine wave inverter AC output voltage. Most AC loads, including computers,
will operate with no problem on quasi sine wave. Inexpensive motors may have a more noticeable electrical
"hum." An average responding volt meter will display AC voltages ranging from 95 to 135 volts, inversely
proportional to battery voltage, and the AC voltage displayed will change as battery voltage changes.
4.2
LOAD DEMAND FEATURE AND LOAD DEMAND MODE:
The Load Demand Feature is an energy conserving feature. This mode allows the inverter to go to sleep
when the inverter is ON and the AC load has been less than 5 watts for approximately 5 seconds. The
‘Load Demand Mode’ is often also described as ‘stand-by mode’ or ‘sleep mode’. While in the ‘Load
Demand Mode’ the inverter does not produce 120 volts AC. When an AC load greater than five watts is
sensed, the inverter will turn fully ON.
Some electronic or variable speed loads may not turn ON while the inverter is in Load Demand Mode. The
load waits to see AC power and the inverter waits to see the load. For these loads, setting Selector Switch
