Advantages of Pure Sine Wave inverters over modified sine wave inverters:
a) Output voltage wave form is pure sine wave with very low harmonic distortion and clean power
like utility-supplied electricity.
b) Inductive loads like microwave ovens and motors run faster, quieter and cooler.
c) Reduces audible and electrical noise in fans, fluorescent lights, audio amplifiers, TV,
Game consoles, Fax, and answering machines.
d) Prevents crashes in computers, weird print out, and glitches and noise in monitors.
e) Reliably powers the following devices that will normally not work with modified sine wave
Laser printers, photocopiers, magneto-optical hard drives
Certain laptop computers (you should check with your manufacturer)
Some fluorescent lights with electronic ballasts
Power tools employing "solid state" power or variable speed control
Some battery chargers for cordless tools
Some new furnaces and pellet stoves with microprocessor control
Digital clocks with radios
Sewing machines with speed/microprocessor control
X-10 home automation system
Medical equipment such as oxygen concentrators
The benefits of using a pure sine wave inverter:
All equipment currently on the market is designed for use with sine waves.
Some appliances, particularly microwaves and variable speed motors, will not produce full output
if they do not use sine wave power.
Other devices, particularly medical equipment may not function at all unless you use a pure sine
A true sine wave produces a much higher equivalent wattage compared to a modified sine wave
power inverter. It is somehow believed that the more you will be using this type of inverter, the
greater the variety of electrical devices and appliances you will be powering.
