Operating a 12,000 square meter automated facility in Shenzhen, we leverage Industry 4.0 principles to ensure supply chain agility and precision engineering in every cell.
From LiFePO4 (LFP) dominance to the emergence of Sodium-Ion (Na-Ion) technologies, we provide the technical roadmap for the next decade of storage.
Fully certified with CE, UN38.3, and IEC standards. Our integrated BMS solutions offer multi-layer protection for extreme off-grid environments.
As the global energy landscape shifts toward decentralized power, the role of a Solar Off-Grid Battery Factory has evolved from a simple component manufacturer to a critical strategic partner. At Shenzhen Suntherra Battery Co., Ltd., we recognize that "Information Gain" in the SEO context is not just about keywords; it's about providing deep, actionable insights into the technology that drives energy transition.
In the current off-grid market, LiFePO4 (Lithium Iron Phosphate) remains the gold standard for cycle life and safety. However, Suntherra is leading the transition into Sodium-Ion (Na-ion) batteries. Our 48V 200ah Sodium Ion Rack Mounted Battery represents a breakthrough for regions with extreme temperature fluctuations. Na-ion batteries offer superior performance in cold climates and a lower cost-per-kWh as the technology scales, providing a resilient alternative to lithium-dependent supply chains.
Energy storage is no longer a "one-size-fits-all" market. Our production lines are optimized for diverse scales:
Shenzhen Suntherra Battery Co., Ltd. is a professional manufacturer specializing in solar energy storage batteries and integrated power solutions for global renewable energy markets. Established in 2014 and located in Shenzhen, China, the company has developed into a reliable OEM and ODM supplier focusing on lithium batteries, deep cycle storage systems, and advanced solar energy storage technologies.
Suntherra operates a modern production facility covering approximately 12,000 square meters and employs more than 180 skilled staff members, including battery engineers, R&D specialists, production technicians, quality control inspectors, and international sales professionals. With advanced automated production lines and strict quality assurance systems, the company ensures high performance, safety, and long cycle life for every battery product.
In an era of global supply chain volatility, Suntherra’s efficiency advantage stems from vertical integration. By controlling the BMS (Battery Management System) design and the mechanical structural optimization in-house, we reduce lead times and ensure compatibility with major inverter brands like Victron, Growatt, and Deye.
Our "Factory 4.0" approach includes:
Supporting distributors across Europe, North America, Africa, and Southeast Asia.
We provide localized technical manuals, compliance certifications for specific regions (like UL for North America or CE for Europe), and technical training for installation teams.
Expertise in Class 9 Hazardous Goods shipping. We handle the complexities of UN38.3 testing and MSDS documentation to ensure your battery shipments arrive without customs delays.
From custom voltage configurations (24V to 800V+) to bespoke BMS protocols for proprietary communication, our R&D team works as an extension of your own engineering department.
Our LiFePO4 systems typically offer over 6,000 cycles at 80% Depth of Discharge (DoD), which equates to approximately 10-15 years of daily use. Our Sodium-ion cells are targeting similar cycles with better performance at low temperatures.
Yes. Our batteries support communication via RS485, CAN, and Bluetooth. We are compatible with major brands including Victron, Deye, Growatt, Solark, and Goodwe.
Sodium-Ion is ideal for regions with temperatures below -20°C where Lithium batteries struggle. It is also more sustainable and less prone to the price volatility of Lithium carbonate.
All Suntherra products are manufactured under ISO9001 and hold CE, ROHS, UN38.3, and IEC62619 certifications, ensuring they meet the safety standards for global markets.
