Description
200KW Bidirectional AC/DC Power Energy System
Model: BIM75040-200KW | Updated: 2026-05-28
🔋 Product Overview
A high-efficiency, high-reliability bidirectional AC/DC power energy system designed for energy storage and V2G applications. It supports bidirectional energy flow between the grid and battery, enabling both charging and discharging functions in a single unit. The system features high-frequency isolation, wide voltage range compatibility, and flexible parallel expansion for diverse use cases.
✨ Core Features & Advantages
Enhanced Safety & Reliability
High-frequency isolation design ensures safety between battery and grid/load. DSP+CPLD digital control with multi-level protection against overcurrent, overvoltage, and overtemperature. Dual DSP design and support for up to 12 parallel modules for stable performance and flexible expansion.
Higher Efficiency
Eliminates line frequency transformer for higher overall efficiency (up to 95% with SiC components, 94% with Si components). The DC/DC converter uses soft-switching resonant technology, achieving up to 98% efficiency.
Intelligent & User-Friendly
Seamless grid connection/disconnection with STS module. Supports wide battery voltage range (100V~750Vdc) for passenger vehicles and 50/60Hz adaptive grid frequency.
Lower Cost & Flexible Configuration
Combines charging and inversion in one unit to reduce costs. Standard 19-inch rack installation with hot-swappable modules for flexible system design.
