VoltPack
Liquid-Cooled Large Container Energy Storage System
Large Container Energy Storage System
The Voltpack BESS utilizes advanced LFP (Lithium Iron Phosphate) cell chemistry with a 12-patented low calorific value architecture. Featuring our innovative DC/AC cabinets and an automated active fire protection system, it guarantees superior safety verified by UL 9540A testing.
Its cylindrical cell design with full polar lugs improves efficiency by 3%, while our optimized nodes and state-of-the-art liquid-cooling thermal management system boost the overall Round-Trip Efficiency (RTE) to over 92%, surpassing the industry average. A welding-free design ensures a 10-20 year lifespan and significantly lowers O&M costs.
Easy & Rapid Installation
Each Voltpack unit comes factory-integrated and fully assembled, ready for immediate “plug-and-play” operation. By removing the middle aisle, capacity reaches 2.2 MWh in a standard 20-foot footprint, maximizing energy density while minimizing deployment time. The system requires minimal on-site maintenance and is backed by a robust warranty of up to 20 years.
Fully Integrated Modular Architecture
Voltpack offers superior power and reliability at a lower lifetime cost. Each battery module is equipped with dedicated inverters (PCS), enhancing system-level efficiency and isolating potential faults to ensure heightened safety. Thanks to seamless over-the-air (OTA) software updates, Voltpack continuously improves, delivering even greater commercial value over time.
Safe by Design: Cell-to-System Protection
Voltpack stands out as one of the safest utility-scale battery storage solutions available. It undergoes rigorous fire testing and is equipped with advanced multi-level safety systems—including combustible gas detection, active smoke extraction, and targeted fire suppression. Paired with 24/7 remote monitoring, you are guaranteed absolute peace of mind.
Intelligent EMS Integration
A high-performance energy storage OS engineered to support decarbonized electricity grids. Leverage our proprietary Energy Management System (EMS) for dynamic application stacking, real-time dispatch, and automated grid market bidding, ensuring maximum ROI for utility and C&I profiles.
Versatile Grid-Scale Applications
Renewable Integration
Store excess solar and wind generation. Dispatch firm, dispatchable clean energy precisely when demand peaks.
Peak Shaving
Reduce costly demand charges for C&I facilities by discharging stored energy during peak tariff periods.
Frequency Regulation
Provide sub-second power injection or absorption to stabilize grid frequency and voltage fluctuations.
Microgrids & Resilience
Ensure uninterruptible power supply for remote communities or mission-critical facilities during outages.
