Against the backdrop of a global energy transition and the explosive growth in demand for photovoltaic (PV) storage, lithium battery technology is entering a golden age of development. In sectors such as distributed energy, residential storage, and small-to-medium commercial and industrial (C&I) storage, products characterized by high safety, compatibility, and scalability are becoming the market standard.
Navigating these trends, ONESUN has leveraged its forward-looking technical layout and innovation to launch the ECO Series energy storage batteries, establishing itself as a benchmark brand in the industry.
Product Innovation: Redefining Modular Storage
The ONESUN ECO Series covers mainstream specifications, including 24V 200Ah and 51.2V 300Ah/314Ah. Utilizing high-performance Lithium Iron Phosphate (LiFePO4) cells and an in-house developed intelligent Battery Management System (BMS), the series features a wall-mounted, low-voltage, expandable design.
Pioneering Concept: ONESUN was among the first companies in China to define and implement the "modular low-voltage storage battery" model, optimizing space utilization and installation flexibility for home and light commercial use.
High Performance: The system supports a 1C continuous charge/discharge rate, allowing for rapid energy storage and release.
Universal Compatibility: It is engineered to integrate seamlessly with the vast majority of mainstream single-phase inverter brands, significantly reducing system integration difficulty and commissioning costs.
Safety and Longevity: The Triple-Layer Shield
Safety is the cornerstone of the ECO Series, built upon an industry-leading "Triple Safety Protection System."
Early Warning: Real-time monitoring of voltage, current, and temperature.
Protection: Immediate intervention during standard fluctuations.
Deep Protection: Fail-safe mechanisms for critical stability.
To extend service life, ONESUN introduced "Active + Passive" Dual Balancing Technology. By dynamically adjusting the state of individual cells during operation, the system minimizes capacity inconsistency and delays aging, ensuring long-term stability and a higher Return on Investment (ROI).
Scalability and Business Flexibility
The ECO Series supports multi-unit paralleling, following a "pay-as-you-grow" philosophy. This allows users to increase capacity as their energy needs evolve, minimizing initial capital expenditure.
Beyond manufacturing, ONESUN operates as a global leader in integrated PV storage solutions. They offer a versatile range of partnership models for B2B clients:
Integrated Services: From battery cells and PACKs to complete systems.
Flexible Cooperation: Supporting OEM, ODM, and SKD/CKD (Semi/Completely Knocked Down) modes.
Agile Factory Model: In response to the "localized manufacturing" trend, ONESUN helps partners establish local assembly plants quickly through standardized products and modular production schemes, lowering market entry barriers.
