Shanghai, Sept. 11, 2025 – The global transition toward clean, reliable, and scalable energy solutions continues to accelerate, and Sermatec has stepped into the spotlight with the launch of its innovative 835kWh Modular Energy Storage System. This breakthrough product combines cutting-edge engineering, intelligent management, and unmatched scalability to address the growing needs of industrial, commercial, and utility-scale energy users.
As renewable energy adoption surges, the demand for robust storage solutions that can stabilize power supply, reduce costs, and ensure resilience is greater than ever. Sermatec’s latest system is not just an energy storage solution — it’s a future-ready platform engineered for flexibility, safety, and maximum efficiency.
A Perfect Balance: 835kWh “Sweet Spot” Capacity
At the heart of Sermatec’s new system lies a 1P104S large-pack architecture paired with an 835kWh capacity, a carefully chosen “sweet spot” that meets the precise demands of mid- to large-scale energy storage. While ultra-large systems above 5MWh often require custom downsizing and long commissioning cycles, Sermatec’s 835kWh design provides the optimal balance between flexibility and efficiency.
This capacity allows the system to be easily scaled up through parallel expansion, reaching as much as 6.68MWh. Whether for large industrial parks or utility-scale power grids, the system adapts seamlessly, avoiding unnecessary upfront investment while supporting long-term scalability.
Its compatibility with multiple voltage levels and MVS cabinets enables smooth integration into centralized inverter stations or string inverter-booster cabins, maximizing asset utilization across diverse applications.
Plug-and-Play Efficiency: Speeding Up Deployment
Traditional oversized containerized storage solutions often face challenges in transport, installation, and commissioning. Sermatec has solved this with an industry-leading modular transport design weighing under 8 tons per module.
This lightweight yet robust structure simplifies global transportation by land or sea, making deployment faster and more cost-efficient. On-site delivery is streamlined, and installation is accelerated thanks to standardized interfaces and quick-connect modules, which drastically cut commissioning time.
The result? Lower project costs, faster rollouts, and earlier value capture for businesses and utilities looking to scale renewable energy use.
Intelligent Management: Smarter, Safer, More Reliable
Beyond hardware, Sermatec integrates a suite of intelligent management features that ensure long-term efficiency, safety, and reliability.
Key highlights include:
- Predictive fault diagnostics to identify and resolve issues before they escalate.
- Remote wireless operation for flexible, real-time monitoring.
- OTA (Over-the-Air) upgrades that keep systems updated with the latest features.
- Cloud-edge-device triple-layer security architecture, protecting against cyber threats while ensuring data integrity.
This digital intelligence not only reduces maintenance costs but also enhances performance by enabling proactive, data-driven decision-making.
Thermal Management: Efficiency Meets Longevity
One of the most critical aspects of battery performance is temperature regulation. Sermatec’s dynamic liquid cooling thermal management system ensures that cell temperature differentials remain within ≤2.5°C.
This advanced system reduces auxiliary power consumption and extends cooling component lifespan by 20–30%. By maintaining optimal operating conditions, it safeguards both safety and efficiency.
Additionally, with SOX accuracy maintained within 3%, the system ensures reliable capacity performance and stable discharge across 2-, 3-, or 4-hour durations — supporting a wide range of business models, from frequency regulation to peak shaving.
Unlocking Multi-Scenario Value
- Sermatec’s storage system is designed not just for energy storage, but for value creation across multiple scenarios.
- With the optional Sermatec Energy Management System (EMS), operators can unlock applications such as:
- Energy time-shifting for better utilization of renewable energy.
- Frequency regulation to stabilize grid operations.
- Peak shaving to reduce costs during demand surges.
- Solar-storage hybrid integration, supporting both DC and AC coupling for maximum design flexibility.
The system’s intelligent O&M platform further enhances performance. It monitors health in real time, detects anomalies early, and provides expert support — either remotely or onsite. With regular preventive inspections, it ensures uninterrupted, long-lasting operation under even the most demanding conditions.
Designed to withstand temperatures from -30°C to 50°C, altitudes up to 4000m, and equipped with IP55 protection (plus optional C5 anti-corrosion coating), the system is built for global deployment in diverse and harsh environments.
Safety by Design: Multi-Dimensional Protection
When it comes to energy storage, safety is non-negotiable. Sermatec has embedded safety into every layer of its engineering with a multi-level protection framework.
Key safety features include:
- 3-level fuse protection to mitigate electrical faults.
- 4-level management control spanning operational and system safety.
- 5-level safety framework covering cell, structure, electrical, and fire protection.
The system’s triple-level fire protection design ensures rapid detection and suppression in case of emergencies. With insulation materials that provide over 2 hours of fire resistance, the risk of thermal propagation between cabinets is virtually eliminated.
Importantly, the system is certified to meet stringent international safety standards, including IEC62619, IEC63056, IEC62477, IEC61000, and UL9540A. These certifications confirm Sermatec’s commitment to delivering solutions that are globally trusted and compliant.
