single phase solar power inverter 3000w

The pure sine wave inverter is better than the rectified wave inverter and the square wave inverter, which can smoothly output regular and high safety sine wave. 

The wave type is the same as the power supply, which has no damage to the equipment and is more assured to use.

Fully Safety Protections: Isolated Input/Output Design and Soft start tech. Inverter red light will be on and makes alarm’s sound and cut off the electricity automatically when Over voltage, Low voltage, Overload, Over current, Short circuit and Over heat.

Working principle of sine wave inverter.

     Dc voltage is divided into two ways, one to the front stage IC power supply to produce a KHZ level of control signal all the way to the front stage power tube by the control signal to promote the power tube switch constantly make the high frequency transformer primary low voltage high frequency AC (AC at this time although the power is low,#pure sine wave power inverter          but the frequency is quite high, the purpose is to make the transformer after the stage to produce a high voltage, #220v solar inverter        The frequency of the front stage is proportional to the voltage of the output of the back stage, #inverter 6000w        Of course, also in the power tube can withstand the frequency range) through the high frequency transformer output high frequency alternating current and then through the quick recovery diode full bridge rectifier output a high frequency of several hundred V direct current to the power tube after the stage and then by the post-stage IC generated about 50HZ control signal to control the power tube work after the stage and then output 220V50HZ alternating current.
