High Efficiency
■ Advanced three-level technology, max. inverter efficiency 99.03%
■ DC 1500V, reducing system cost
■ With bidirectional converter and BMS to charge or discharge batteries
Power Grid Adaptability
■ Advanced islanding detection technology
■ Low voltage ride-through capacity, reactive power compensation and other functions
■ Off-Grid independent operation
System Characteristics
■ High power density, reducing system land cost
■ Wide DC working voltage range
■ Supporting multi-unit parallel connection function,
expandable to MW power level
■ Stand-alone systems do not require an EMS system and can independently manage the peak-to-peak valley operation
