Dahua Solar Power Solutions PFM377-D4830

Dahua Special Stainless Steel Distribution Box + MPPT controller PFM377-D4830

Special distribution box of solar power supply system

Features:

  • The control system of the solar power supply system, used to control the charge and discharge of the small off-grid solar power system;
  • This product includes a MPPT solar charge and discharge controller, a lightning arrester, a DC circuit breaker and a distribution box, etc.
  • MPPT solar charge and discharge controller: max. MPPT tracking efficiency is up to 99%, can significantly improve the energy utilization of photovoltaic system, which is 15%~20% higher than that of traditional PWM; use advanced digital power supply technology, the efficiency of circuit energy conversion is up to 98%; support automatic identification of system voltage, current limiting charging mode, built-in over temperature protection mechanism, etc.
  • Lightning arrester: max. discharge current 20kA;
  • DC circuit breaker: high arc extinguishing ability, more safe and reliable than the AC circuit breaker;
  • Distribution box: IP54, 1.2mm thick SUS201 material, with the cooling function, when the temperature is higher than 45℃, the fan will open automatically.
