In the context of the global acceleration of energy structure transformation and the intelligent upgrade of power systems, energy storage systems, as the core supporting technology for “new energy + smart grids,” are rapidly becoming a major driving force in energy transformation, entering a fast track for high-quality growth. As a global one-stop zero-carbon energy solution provider and expert in multi-scenario new energy solutions, Q-SUN is closely aligned with the trends in energy transformation and has launched its next-generation smart energy storage system—QS-POWER.

This system, with its leading battery technology, excellent system integration capabilities, and high-quality full lifecycle services, has become a technical benchmark for the small distributed energy storage market, providing flexible, efficient, and safe energy solutions for residential, commercial, and microgrid applications.
One Cluster, One PCS: Building an Efficient Architecture
In terms of system architecture design, QS-POWER breaks away from traditional energy storage models by adopting a “one cluster, one PCS” architecture, replacing the traditional “one cabinet, one PCS” or “one machine, multiple clusters” solutions. This design provides each battery cluster with an independent PCS control unit, allowing precise monitoring and control of cluster-level voltage, current, and SOC. It completely avoids the circulating current issues and thermal runaway risks caused by battery performance inconsistencies in traditional architectures.
With this modular, decoupled architecture design, the QS-POWER system has inherent scalability and fault tolerance. During project construction and operation, it can be flexibly deployed as needed. If a single cluster fails, it only affects that cluster, without impacting other parts of the system, significantly improving system availability and reducing fault downtime and maintenance costs by more than 92%.
Safe and Reliable, Extending the System’s Lifecycle
QS-POWER adheres to the core design principles of high standards, high integration, and high reliability, and has passed international safety certifications such as UL1973, IEC62619, and UN38.3. The entire system adopts natural cooling and direct current out-of-cabinet designs, effectively addressing safety hazards such as short circuits and fires caused by exposed cables in traditional systems, while significantly improving the system’s environmental adaptability. The protection level is IP65, making it suitable for deployment in various indoor and large-scale industrial scenarios.
With a rated capacity of up to 2,967.5 kWh, the system is equipped with high-performance, high-safety LFP cells and supports parallel expansion of up to 8 units, easily meeting diverse large-scale commercial and industrial energy storage requirements. The cells offer a cycle life exceeding 6,000 cycles and a design lifespan of over 20 years, with a recommended DOD of 90%. This ensures long-term stable operation while optimizing the energy efficiency ratio across the entire lifecycle—delivering true “long service life, minimal replacements, and low maintenance.”
Ultra-Simple Deployment for Residential and Small Commercial Use
Extreme Integration and Lightweight Design
The entire unit weighs approximately 130kg, with a compact structure that does not require large machinery for transportation, lifting, or installation. A single person can complete the unboxing, installation, and commissioning within 2 hours. This accelerates the evolution toward a “plug-and-play, one-person installation, and portable” lightweight standard, making it particularly suitable for urban users and commercial scenarios with limited space.
Natural Cooling + Fan-Free Structure
Through precise heat dissipation pathways and low-power control logic, the system achieves natural cooling with an operating noise of less than 30dB, ensuring silent operation. This is ideal for deployment in indoor spaces, commercial streets, and campuses where environmental sensitivity is high.
Flexible Deployment and Modular Expansion
The system supports parallel deployment, capacity expansion, and “install and use as needed” expansion methods. Users can start with a small system and dynamically expand it as their energy demand grows, achieving an “optimal investment curve.”
Smart Collaboration for Visualized Energy Management
In terms of system intelligence, QS-POWER supports Bluetooth and Wi-Fi remote communication. Combined with the intelligent Battery Management System (BMS) and central control platform, it allows multi-dimensional data collection and real-time visualization of key parameters such as voltage, current, and temperature to ensure safe operation. Through a cloud-based architecture, users can remotely monitor the device status, access anomaly alerts, data logs, remote diagnostics, and firmware upgrades, significantly simplifying operation and maintenance processes.
Drawing on the EMS architecture of large-scale energy storage stations with GWh capacities, it integrates intelligent algorithms such as electricity price optimization, peak-valley arbitrage, load forecasting, and energy storage scheduling. This enables the system to autonomously manage energy and respond to local loads, maximizing energy utilization and minimizing electricity costs.
For residential energy storage applications, QS-POWER is engineered with a comprehensive focus on household power safety, cost-effectiveness, and intelligent energy management. The system utilizes high-safety 51.2V 320Ah Grade-A LFP cells and achieves a protection rating of IP21. It seamlessly integrates with PV systems, EV chargers, and home energy management systems, supporting smooth on-grid/off-grid switching to enable an all-in-one strategy of “self-consumption, surplus energy storage, and peak–valley load shifting.” Compared with conventional energy storage systems, QS-POWER delivers significant advantages in power response speed, scheduling algorithm precision, and long-term operational stability—capable of completing load transfer within milliseconds to ensure uninterrupted operation of critical appliances during unexpected outages. By continuously learning and optimizing based on household consumption patterns and dynamic electricity pricing curves, the system intelligently adjusts charge–discharge strategies, transforming storage from a “backup battery” into a true household economic asset. With simultaneous improvements in energy security, energy self-sufficiency, and energy cost optimization, QS-POWER establishes a residential energy ecosystem that is both highly reliable and exceptionally efficient.
QS-POWER is not just an energy storage device but a key solution for the future smart energy ecosystem. Its highly modular, integrated, and intelligent features make it widely applicable in various typical scenarios, including residential solar-storage systems, small commercial load adjustments, building microgrids, and solar-storage-charging integrated stations. Its quiet operation, lightweight design, and flexible expansion capabilities also make it an ideal choice for urban environments, space-limited
Under the guidance of global carbon peak and carbon neutrality goals, QS-POWER will continue to drive innovation through technology, leading the next generation of smart energy storage systems toward higher efficiency, stronger security, and broader application boundaries in the new era.
