204.8V-768V High-Voltage Rack-Mounted Battery

The 204.8V-768V High-Voltage Rack-Mounted Battery is a scalable, high-capacity LiFePO4 energy storage system built from 16.08KWh 51.2V 314Ah battery modules. This High-Voltage Battery is an ideal solution for large-scale commercial & industrial energy storage, utility-scale solar integration, and heavy-duty backup power applications.

Core Advantages:

1. Modular & Scalable Architecture
Built from 16.08KWh single modules connected in series, this Rack Mounted Battery system supports flexible voltage configurations from 204.8V to 768V. The 4S, 6S, 13S, and 15S options deliver 64.3KWh to 241.15KWh total energy, allowing B2B customers to right-size systems for large-scale projects and scale as energy demands grow.

2. High-Voltage Efficiency for Large Systems
As a High-Voltage Battery, the 768V configuration significantly reduces current levels for a given power output, enabling smaller cable cross-sections, lower transmission losses, and higher inverter efficiency compared to low-voltage alternatives. This makes the 768V Rack Mounted Battery particularly suitable for multi-megawatt commercial and utility installations.

3. Massive Energy Capacity
With system energy ranging from 64.3KWh to 241.15KWh per cluster and 314Ah capacity across all configurations, this Rack Mounted Battery series delivers industry-leading energy density. The 15S 768V configuration provides 241.15KWh of storage capacity, reducing the number of parallel strings required for large-scale projects.

4. Ultra-Long Cycle Life
Engineered with Grade A prismatic LiFePO4 cells, the 768V Rack Mounted Battery delivers ≥6,000 cycles at 90% DOD while maintaining 80% State of Health. Under standard operating conditions (25°C, 0.5C rate), this translates to over 10 years of reliable daily operation, significantly reducing total cost of ownership for commercial and industrial installations.

5. Intelligent Battery Management System (BMS)
The integrated BMS provides comprehensive protection and monitoring:

Overcharge / Over-discharge protection

Overcurrent and short circuit protection

Temperature monitoring and thermal management

Active cell balancing for extended cycle life

Real-time SOC and SOH monitoring

Bluetooth and Wi-Fi wireless connectivity for remote monitoring via mobile applications
