Sol-SF-xK Series 8K-20K


Off-grid solar power system is an independent renewable power supply system widely applied in places without effective power such as remote mountain areas,pasturing areas, sea islands, communication base stations, fled operation area sand street lights, etc. The of-grid system consists of solar modules, solar controllers,battery bank, f-grid inverter, AC load etc

Feature

  • With Transformer.
  • Pure sine wave outout , suitable for all sorts of electrical appliances With IGBT Module.
  • Mains supply priority model , saving mode and battery priority mode are all settable , thus making it easy to meet different application needs of users.
  • WIFI monitor for optional.
  • LCD touch screen for visualzation of operation.
  • Overall protection functions ( battery overcharge protection , battery under voltage protection , overload protection, short circuit protection and over).
