Solar King Specs

SOLAR KING 1500 / 2000 / 3000 / 4000 / 6000

Full Specifications:
 

Features :

  1. Anti-Islanding detection methods: Frequency, voltage and utility impedance.
  2. Build-in MPPT (Maximum Power Point Tracking) function.
  3. High efficiency with wide range operation.
  4. Design to meet VDE0126-1-1 requirements.
  5. Easy assembly in production line.
  6. Easy replacement when servicing. The mean time of service is less than
    20 minutes.
  7. Firmware flash capability: The firmware inside the micro-controllers can be updated by optional communication interface.
  8. GFCI: Ground Fault Current Interruption, which is also known as RCD (Residual Current Device). To prevent electrical hazard of user, a current transformer monitoring the difference between L and N current is applied. When the current difference is larger than specified value stated in section ¡§General Data¡¨, inverter will cut its output to grid.
  9. Bundled software for user buying optional communication card.
