Sunenergy System


This junction box differs from other models with fewer terminals due to its components and manufacturing model. It has the following characteristics:
  • Box material: SABIC PPO (PX9406P) (f1) for outdoor engineering plastic, good weather fastness, flame class: UL94V-0.
  • Metallic material: (C1100) Pure copper, Cu+Ag CuAg: ≥ 99.90%, with excellent conductivity.
  • Seal Material: Dow Corning flame resistant silicone, features good weather fastness, anti-vibration, moisture resistance, anti-corrosion and thermostability.
  • Diode: Manufactured by Diotec from Germany for the photovoltaic module. Its electrical property is better than other similar products, especially with large current and high voltage
  • Tape Connection: Welding or clamping is reliable for tapes. The contact areas are larger and the contact resistance is smaller.
  • Diode connection: Diode contact areas with metals are larger, thermolysis is good.
