Product Description
Power Conversion Inverter System Diagram
Power Conversion Inverter System
The Power Conversion Inverter (PCI) serves as the central control unit in energy storage systems, managing the bidirectional conversion between alternating current (AC) and direct current (DC). This advanced component enables efficient energy flow regulation and storage management.
During charging cycles, the PCI converts surplus AC power from the grid or photovoltaic inverters into DC power for battery storage through rectification. During discharge, it transforms stored DC electricity back into usable AC power through inversion, supplying energy to the grid or connected loads.
The system supports both grid-tied and off-grid operations, allowing seamless transitions between main grid connectivity and independent microgrid functionality based on power demands and system configuration requirements.
Smart Energy Management Features
  • EMS Smart Energy Management System with multiple configurable operation modes
  • LCD smart touch screen display for intuitive control and monitoring
  • AC and DC dual backup options for reliable auxiliary power
  • Advanced unbalanced load management technology for system stability
  • RS-485 Modbus RTU protocol communication for device integration
  • Optional WiFi/LAN remote monitoring and control via dedicated app
  • Optional Static Transfer Switch (STS) support for grid-tie and off-grid applications
