Technical Architecture
The IMAX HV-DC series employs a rack-mounted modular design based on 1P16S LiFePO₄ battery modules. Each module integrates battery cells, BMS, and thermal management into a compact 660×440×230 mm enclosure. The system scales from 5 to 10 modules, delivering nominal voltages from 256 Vdc to 512 Vdc with a consistent 200 Ah cell capacity.
Advanced bidirectional power conversion supports 100 A max charge/discharge current, while the natural cooling architecture ensures silent, maintenance-friendly operation. The modular topology enables parallel connection of multiple units for expanded capacity and redundancy.
Application Positioning
Engineered for commercial & industrial energy storage, microgrid stabilization, solar-plus-storage integration, and EV charging infrastructure. The high-voltage DC architecture minimizes conversion losses and reduces cable cross-section requirements, making it ideal for medium-to-large scale distributed energy systems.
As an original equipment manufacturer (OEM), IMAXPWR delivers tailored solutions that meet diverse grid codes and project-specific requirements across renewable energy, backup power, and peak-shaving applications.
