Power Conversion System BCS500K-A Kehua

The BCS500K-A bidirectional converter from Kehua is designed for use with industrial energy storage systems and large systems.

BCS-A series energy-storage converter is researched and developed by Kehua Company, and it is used in the link of energy-storage. The basic feature is bidirection (rectification, inversion), and it equips a series of special performance and can be used in grid-connected and off-grid. It can regulate and control the electricity resource effectively and balance the difference of used electricity in different seasons and day and night, and also, it guarantees the safety of grid. It is the important premise of renewable energy sources and the effective means for achieving the interaction management of grid. The energy-storage converter is the necessary link for achieving smart grid. The energy-storage system is made up of energy-storage batteries, energy-storage converter and distribution system, boost transformer and load.

Product Features:

High Efficiency

• Integrated output isolation transformer
• With bidirectional converter to charge or discharge batteries
• Optional modes for charging, including constant current charging, equalized charging and floating charging

Power Grid Adaptability

• Meeting the smart grid design specification and allowing power grid dispatching
• Advanced islanding detection technology
