ACE HV ESS Modular High-Voltage Stackable LFP Battery System (5.12kWh - 30.72kWh)6

Product Description:
Power Your Energy Independence with ACE HV ESS
Lithiumvalley’s ACE HV ESS revolutionizes residential and commercial energy storage with its high-voltage, modular LiFePO4 battery system. Engineered for flexibility and performance, this stackable solution enables effortless customization to match your exact energy needs—from compact 15.36kWh setups to robust 30.72kWh configurations.

Core Technology
Each 5.12kWh module delivers 51.2V/100Ah of reliable power using premium cobalt-free Lithium Iron Phosphate (LFP) cells. The high-voltage architecture (153.6V–307.2V) minimizes energy loss while supporting 100A continuous charge/discharge currents. With natural convection cooling and IP-rated protection, the system operates flawlessly in indoor environments (-20°C to 60°C discharge range).

Seamless Integration
The stackable design allows vertical expansion (3–6 layers) and parallel clustering (up to 4 clusters). Wireless communication and standardized dimensions (610×225 mm footprint) enable rapid installation. Real-time monitoring via SOC/voltage displays and RS485/CAN connectivity ensures compatibility with major solar inverters for on/off-grid applications.

Enduring Performance
Backed by 6,000 cycles at 80% depth of discharge (DoD) and certifications including UL1973, IEC62619, and CE, the ACE HV ESS guarantees decade-long reliability. Weighing just 48.5kg per battery module, its lightweight yet durable construction simplifies handling without compromising safety.
