China MC4 Inline Blocking Diode Connector Manufacturer

  • Waterproof Level:IP68 Standard MC4 Diode Connector
  • When there are more solar cell modules connected in series to form a square cell array, an MC4 diode needs to be connected in reverse parallel at the positive and negative output terminals of each cell panel. The function of the diode at this time is to prevent a certain component in the square array or a certain part of the component from being shaded or malfunctioning to stop power generation. A forward bias will be formed at the two ends of the bypass diode of the component to make the diode conduct. The working current of the component string bypasses the faulty component and flows through the diode without affecting the power generation of other normal components. At the same time, it also protects the bypassed component from high forward bias or damage.
