  • Highly adaptive capacity for mains grid: The system supports wide input voltage range (85~300VAC), which increase the adaptive capacity for adverse mains grid 
  • High efficiency: Efficiency of high-efficiency rectifier can be up to 95.5%, system efficiency can be above 95% 
  • High reliability: The system has perfect lightning protection at both AC side and DC side and supports use with outdoor cabinet
  • Perfect battery management function: The management functions include BLVD, temperature compensation, auto voltage regulation, step-less current limiting, battery capacity calculation and on-line battery test, etc., which efficiently prolong battery life
  • Energy conservation and environment protection: The system supports auto dormancy function and high-efficiency and common rectifier mixing function
  • Multiple communication ports: The system provides multiple communication ports like RS232, Ethernet port, dry contacts, etc., which enables flexible networking and remote monitoring
