6. FAQ, Frequently Asked Question
6.1. What is the difference of pure sine wave inverter and modified sine wave
inverter.
Modified sine wave inverter use less elaborate switching and filtering circuitry.
There would be electrical noises or interference which can prevent these
inverter from properly powering certain loads. The frequency and voltage to
their outputs may vary and contain some noise and distortion. It can run some
resistive load like light bulb ect. But it is not good for many appliances and
affects use life of the appliances.
Pure sine wave inverter produces the pure sine wave power which is as good
as the grid power. With today’s technological advancements,there are more
electronics which require true sine wave power to operate correctly. Pure sine
wave inverters are designed to emulate the power. Some appliances require
pure sine wave, including computers, digital clock, battery charger, light
dimmers, auto and visual equipment, variable speed motors, pump, air
conditioner, and precision machines, induction cooker, micro wave oven,
compressor, water pump, ect.Pure sine wave inverters have distinct advantage
over modified sine wave inverters in terms of performance, power
consumption.Choose pure sine wave inverter for the goodness and longevity
of your appliances.
