Amid the global transition to clean energy, the integration of distributed photovoltaics and energy storage has become a key solution for addressing the volatility of renewable energy and improving energy efficiency. Jiangsu Xinya Wisdom New Energy Co., Ltd.’s 1MW high-voltage containerized battery energy storage system (Bess Batteries for Solar System) offers a standardized design, high reliability, and flexible adaptability, providing an integrated solution for large-scale energy storage projects. The system’s technical details and service capabilities were recently fully disclosed on its official website.
Core Product: 1MW High-Voltage Containerized Energy Storage System, an “Energy Manager” Suitable for Multiple Scenarios
This energy storage system, designed with “efficiency, safety, and longevity” as its core objectives, utilizes a 40-foot standard container design and integrates a complete suite of equipment, including lithium-ion batteries (primarily lithium iron phosphate batteries), a PCS converter, thermal management, and fire and security systems. It can be directly connected to distributed photovoltaic systems, the power grid, and loads. Its primary applications are solar energy storage and absorption, grid peak shifting and valley shifting, and emergency backup power, covering large-scale energy demand scenarios such as industrial and commercial parks and new energy power plants.
Key performance parameters demonstrate outstanding durability and stability: a battery cycle life of 6,000 cycles (at 100% deep discharge), far exceeding the industry average; a charge/discharge current of 0.5C and a conversion efficiency of 98%, ensuring maximum energy utilization. Equipped with a proprietary battery management system (BMS) and balancing control system, the system not only monitors battery status in real time and provides fault warnings, but also maintains battery consistency through active balancing technology, extending overall system life. The system has obtained multiple international certifications, including CE, UN38.3, and MSDS, ensuring safety and compliance that meet global market requirements.
The system’s hardware design incorporates multiple protective features: a high-strength container structure withstands extreme conditions such as long-distance transportation turbulence and earthquakes; a proprietary fire extinguishing system and escape door/lock design provide dual fire safety features; and liquid cooling technology (optional air cooling) is used for thermal management, coupled with temperature compensation parameter control (the battery’s maximum operating temperature is limited to 45°C, with a temperature differential of 5°C) to ensure stable battery operation in diverse environments. The standardized modular design provides flexible scalability, allowing for the addition and removal of units based on project needs while reducing ongoing maintenance.
System Architecture: From “Component Integration” to “Intelligent Scheduling,” Full-Chain Energy Management
Unlike traditional single-unit energy storage devices, this product, centered around an “integrated microgrid system,” provides a comprehensive management system encompassing energy generation, storage, scheduling, and consumption. The core components of the system include six modules:
1. Lithium Iron Phosphate Battery System: Serving as the energy storage core, it utilizes 3.2V, 100AH prismatic cells and utilizes efficient connection technology to achieve low-impedance, highly consistent power transmission.
2. PCS Bidirectional Converter: Each unit has a power output of 500kW and supports parallel connection of multiple units, enabling flexible adaptation to various scenarios such as photovoltaic charging and grid interaction. It features programmable operating modes and remote control capabilities.
3. Environmental Control and Security System: Including HVAC, fire protection lighting, and lightning protection devices to ensure a stable operating environment for the equipment.
4. Intelligent Power Distribution Unit: Integrated AC/DC distribution cabinets enable flexible switching between the grid, loads, and energy storage systems.
5. The SCADA monitoring and EMS energy management system serves as the “brain center,” supporting real-time data collection (such as AC bus voltage, frequency, and charge and discharge power), historical data storage (retained for one month), fault alarms, and intelligent scheduling. For example, by setting SOC (State of Charge) lower limits for peak, valley, and flat periods (10% during peak, 40% during flat, and 90% during valley), it automatically implements off-peak charging and peak discharging, maximizing user economic benefits.
6. Communication Interface: Supports RS485 and Ethernet communication, enabling access to a remote monitoring platform for unmanned and remote operation and maintenance.
Actual operational data demonstrates that the system accurately suppresses power fluctuations when connected to the grid (as demonstrated in the PCC power fluctuation stabilization experiment). Furthermore, its “anti-backflow control” function prevents excess photovoltaic power from being fed back into the grid, complying with distributed energy management regulations.
Company Strength: 13 years of experience, providing comprehensive support from “manufacturing” to “service.”
As the powerhouse behind the system, Jiangsu Xinya Smart New Energy has demonstrated solid manufacturing and service capabilities. Founded 13 years ago, with registered capital of US$2 million, the company boasts a 50,000-square-meter production base, 345 sets of production equipment, and a staff of 456 (including 50 R&D personnel and 56 quality control personnel). This exemplifies an integrated “R&D + Production” manufacturer, rather than a trading operation, enabling direct control over product quality and delivery cycles.
In terms of supply chain and delivery capabilities, the company can produce 1,000 energy storage units per month. Small orders (1-10 units) have a delivery lead time of 90 days, with shorter lead times negotiable for larger orders. The company uses individual cartons (over 840*175*395mm, gross weight 7.28kg), and supports shipping from multiple ports, including Shenzhen, Guangzhou, Wuhan, Ningbo, and Qingdao, to meet the needs of global customers. The company also offers flexible customization services, including OEM/ODM support. Sample preparation takes only 3-5 days (7-15 days for custom samples), and mold costs are waived, enabling rapid response to individual customer needs.
Market Value: Supporting the “Dual Carbon” Goals and Unlocking New Application Scenarios for New Energy
Driven by the “Dual Carbon” goals, the distributed PV + energy storage model has become a crucial tool for reducing costs in the commercial and industrial sectors and for shifting peak loads and filling off-peak loads on the power grid. The launch of this 1MW energy storage system not only provides a standardized, plug-and-play solution for large-scale projects, but its long cycle life of 6,000 cycles and intelligent scheduling capabilities also significantly reduce overall lifecycle costs. For example, in industrial and commercial parks, by arbitrage between peak and off-peak electricity prices and combining it with self-use of PV power, the energy storage system investment is expected to recover in 3-5 years, while also reducing CO₂ emissions (data on this page indicates that the project can achieve an annual CO₂ reduction of up to 826.8 tons), achieving both economic and environmental benefits.
Furthermore, the system’s modular design and multi-scenario adaptability can be extended to emerging areas such as off-grid microgrids (e.g., power supply in remote areas) and integrated PV, storage, and charging stations, providing technical support for expanding the boundaries of new energy applications.
From technical specifications to service offerings, Jiangsu Xinya Smart New Energy’s 1MW high-voltage containerized energy storage system demonstrates both the strength of Chinese energy storage companies in hardware manufacturing and the soft power of software empowerment through intelligent management systems and customized services. Against the backdrop of the accelerating expansion of the global energy storage market, this type of product, offering high cost-effectiveness, long lifespan, and robust service, is expected to become a key link between clean energy and end users, injecting greater certainty into the energy transition.
