INPPCS energy storage converter

   Peak load shifting, smooth voltage fluctuation, elimination of sudden change, improving the quality of power grid ■ Improve the utilization of new energy and economic efficiency ■ Use of backup and emergency power supply ■ Microgrid application


 Product Principle

  The INPPCS converter can realize the AC and DC conversion between the power grid and the battery, and complete the two-way energy flow between them. It is the main executive mechanism and core component of the energy storage system. Through the advanced control strategy, the converter realizes the charging and discharging management of the battery system, the charging and discharging power control of the battery energy storage system, the operating mode and mode switching functions of the grid connection/off grid; At the same time, it has perfect protection functions, such as islanding protection, DC overvoltage protection and low voltage ride through and meets the requirements of grid connection and off grid.    

 Typical application

  1. Energy storage + Power grid Peak load shifting, frequency adjustment, backup power supply     2. Microgrid Power supply for electricity free area, island, and other areas      
Energy storage + Renewable energy Energy storage + Renewable energy + Oil engine
  3. Mixed application energy storage + Power grid + Renewable energy
