Features

  • High reliability

    Frequency tracking, noise filtering and low distortion in inverter output because of double—conversion design

  • High adaptability

    A wide range of input frequency, which realizes stable operation of fuel generators High optimal performance of the battery An intelligent battery management technology, which guarantees a longer battery life and decreases the times of battery maintenance

    An advanced constant-voltage charge technology. which activates the battery to the most extent, saves the charge time and guarantees a longer battery life

  • Overall and reliable protection

    A power-on test function, which can avoid the faults because of hazards of the inverter

  • Efficient IGBT (Insulated Gate Bipolar Transistor) inversion technology Good high-speed switching feature,large-voltage and large-current operating characteristics, and voltage drive of IGBT (The fifth-generation IGBT has a lower saturation voltage drop and higher operation efficiency and reliability.)
