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, but the frequency is quite high, #low frequency 2kw 12v solar inverter        the purpose is to make the transformer after the stage to produce a high voltage, #5 kw inverter solar          The frequency of the front stage is proportional to the voltage of the output of the back stage, Of course, #off grid inverter        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.

CPU management, intelligent control, modular composition, more convenient after-sales maintenance;

LED+LCD display, can visually display all the running parameters of the machine.

Operate and use in strict accordance with the requirements of the operation and maintenance manual of the photovoltaic inverter.

When the inverter is working in battery mode, if one or more phases fail, the inverter will have no output and cannot be loaded.
