Product Portfolio

The company’s product portfolio is characterized by high integration, compact footprint, and multi-scenario adaptability, with core offerings spanning both liquid-cooled and air-cooled energy storage series.

✤ 261 kWh Liquid-Cooled Energy Storage Cabinet

After six generations of iteration, this model occupies only 1.2 m², making it one of the smallest liquid-cooled energy storage cabinets in its class. Compared with conventional liquid-cooled systems, it reduces installation space by 30–40%, making it ideal for space-constrained industrial parks while supporting flexible capacity expansion.

✤ 522 kWh Liquid-Cooled Energy Storage Cabinet

Launched in 2025, this highly integrated solution incorporates an AI-powered cloud management platform. It can be flexibly combined with the 261 kWh liquid-cooled cabinets to further increase system capacity and improve operation and maintenance efficiency, making it suitable for large-capacity energy storage applications.

✤ 104 kWh Liquid-Cooled PV-Storage-Charging Integrated System

Available in 60 kW / 104 kWh (using 0.5C lithium iron phosphate cells) with dual DC charging guns, and 120 kW / 104 kWh (using 1C fast-charging lithium iron phosphate cells).
The system can be directly connected to photovoltaic panels and operates without grid power, eliminating the need for transformers and extensive cabling. It enables rapid deployment and flexible configuration, making it well-suited for regions with insufficient or unstable power supply.

✤ 215 kWh Air-Cooled Energy Storage Cabinet

With a footprint of 1.9 m², this cabinet is designed for small to medium-scale commercial and industrial applications where installation space is relatively sufficient. It meets basic requirements for peak shaving, valley filling, and emergency backup power.

✤ 104 kWh Liquid-Cooled PV-Storage-Diesel Integrated System

Designed for various small and medium-scale commercial and industrial scenarios, this system supports connections to photovoltaic systems and diesel generators, fulfilling the needs of microgrids and PV + energy storage hybrid systems.All products utilize Tier-1, Grade-A lithium iron phosphate (LFP) battery cells with a cycle life exceeding 8,000 cycles, and are equipped with fire-resistant isolation layers, three-level power-off protection mechanisms, and fully automatic FK-5-1-12 (heptafluoropropane-based) fire suppression systems, ensuring high safety and reliability.

Service Models

The company offers two service models — Direct Purchase and Energy Management — covering the full lifecycle of energy storage systems.

• ▪️ Direct Purchase Model: Customers directly purchase the energy storage equipment. The company provides customized pre-sales solution design, standardized delivery, a 5-year warranty, 24/7 emergency response, and AI cloud platform monitoring services, along with regular battery health inspections to ensure long-term system reliability.
• ▪️ Energy Management Model: With zero upfront investment, customers reduce energy costs by sharing energy storage revenues. The company assumes full responsibility for equipment investment, installation, and ongoing operation & maintenance, making this model especially suitable for small and medium-sized enterprises with limited capital resources.
