PCS energy storage converter

The SDPCS energy storage converter provides an interface between the grid and the energy storage battery to realize the charging and discharging of the energy storage battery system. The energy storage converter can be applied in the grid-connected system to realize frequency modulation, peak regulation, active power reserve, reactive power support, energy transfer and new energy consumption. At the same time, it can also establish voltage source support for off-grid black start to provide backup power for the load. SDPCS energy storage converter adopts advanced digital control technology, which optimizes the control performance and improves the reliability of the system. It is suitable for different battery charge and discharge needs, and the structure is modular design, which is convenient for installation and maintenance.
