Key attributes

Brand Rw Energy
Model NO. Isolated Three-Phase Energy Storage Converter
Rated voltage 400VAC
Rated frequency 50/60Hz
Series RWPCS
Description

The RWPCS Series Isolated Three-Phase Energy Storage Converter is a new-generation power conversion system designed for energy storage applications. With an isolated three-phase structure, it ensures enhanced safety, high efficiency, and stable operation in various industrial and commercial power systems.

This series of converters is capable of bidirectional energy flow, supporting both charging and discharging functions, while providing seamless switching between grid-connected and off-grid modes. The isolation design effectively improves system reliability, protects sensitive equipment, and meets stringent grid code requirements.

The RWPCS series is particularly suitable for:

  • Industrial and commercial energy storage systems
  • Microgrid and distributed energy applications
  • Renewable energy integration (solar, wind, etc.)
  • Backup power supply for critical loads

By optimizing power quality and enabling flexible energy management, the RWPCS converter helps achieve efficient utilization of renewable energy, peak shaving and valley filling, and improved system stability.

Key Features

  • Advanced energy storage coordination control
  • Fast fault detection technology
  • Complete isolation between grid and load
  • Harmonic compensation and reactive power support
  • High power factor, stable charging/discharging performance
  • Grid-connected/off-grid seamless switching (with optional zero-crossing control)
  • Flexible time-segmented charging/discharging function, configurable to site requirements
