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 the high-tech hub of Shenzhen, China, the company has matured into a premier OEM and ODM supplier. Our strategic focus lies in Lithium Iron Phosphate (LiFePO4) technology, deep cycle storage systems, and the next generation of smart energy management.
With a state-of-the-art production facility, Suntherra integrates advanced automated production lines with rigorous Quality Control (QC) protocols. Our engineering team, comprising R&D specialists and battery chemists, ensures that every unit—from residential 12V packs to industrial-grade BESS (Battery Energy Storage Systems)—meets international standards for safety, high performance, and ultra-long cycle life.
Navigating the evolution of Solar Battery Packs from Lead-Acid to Solid-State.
Lithium Iron Phosphate (LFP) remains our flagship chemistry due to its unparalleled thermal stability and 6000+ cycle life. We are now integrating 280Ah and 304Ah high-density cells to reduce the footprint of commercial systems.
The future of energy storage is intelligence. Our new Battery Management Systems utilize AI algorithms for predictive maintenance, State-of-Charge (SoC) precision, and active balancing to extend battery lifespan by 20%.
For extreme climates, Suntherra is pioneering liquid-cooling technology in containerized solutions and self-heating mats for residential batteries, ensuring performance from -20°C to 60°C.
We are investing in "Second Life" battery programs, designing modules that are 95% recyclable to meet upcoming EU and North American environmental mandates.
Our V2G (Vehicle-to-Grid) and Virtual Power Plant (VPP) compatible inverters allow batteries to not only store power but also stabilize the local grid during peak demand.
Our R&D department is actively testing Sodium-Ion (Na-ion) prototypes for cost-sensitive markets where extreme cold performance and lower cost-per-kWh are critical.
The "Made in China" label has evolved into "Intelligently Manufactured in China." At Suntherra, we leverage the most robust supply chain in the world to provide unparalleled value. Our factory utilizes MES (Manufacturing Execution Systems) to track every single cell's journey from incoming inspection to the final assembly of the Solar Battery Pack.
Global disruptions have proven that vertical integration is key. We maintain strategic partnerships with top-tier cell manufacturers (CATL, EVE, BYD) and produce our own BMS and enclosures in-house. This allows us to maintain strict QC and offer competitive pricing even during raw material fluctuations.
Stackable and wall-mounted batteries for homeowners looking to maximize self-consumption and eliminate reliance on rising utility rates.
High-capacity BESS for factories to reduce "Demand Charges" by discharging during peak utility pricing hours, significantly lowering the Levelized Cost of Energy (LCOE).
Reliable backup power for 5G base stations and off-grid remote sensing equipment where maintenance-free operation is mandatory.
Navigating international trade requires more than just a good product. Suntherra provides a comprehensive suite of services to ensure your procurement process is seamless and compliant with regional regulations.
Our products are engineered to meet and exceed global standards: CE, IEC 62619, UN38.3, MSDS, and UL1973. We provide all necessary documentation for hassle-free customs clearance and insurance eligibility.
From private labeling to bespoke BMS communication protocols (CANbus, RS485), we tailor our hardware to fit your brand's specific market ecosystem.
Through our network of dangerous goods (DG) freight forwarders, we offer sea, air, and rail shipping solutions, including DDP (Delivered Duty Paid) to many regions, minimizing risk for our partners.
We provide localized marketing materials, technical training videos, and 24/7 remote technical support to empower your local sales teams.
LiFePO4 (Lithium Iron Phosphate) offers significantly higher safety and a longer cycle life (up to 6000 cycles) compared to standard NCM Lithium-ion batteries. While slightly lower in energy density, LFP is the preferred choice for stationary solar storage due to its non-combustible nature.
We do not recommend mixing different capacities or brands as it can cause imbalances in the BMS, leading to reduced efficiency and potential safety risks. For expansion, always use the same model and version from Suntherra.
Our quality assurance includes cell capacity sorting, internal resistance testing, 100% EOL (End of Line) discharge/charge testing, and aging tests for 48-72 hours before shipping.
Yes, we provide DDP (Delivered Duty Paid) shipping services to the USA, EU, and parts of Southeast Asia, where we handle all customs, duties, and final delivery to your warehouse.
12V systems are ideal for RVs, marine, and small cabins. 48V systems are the industry standard for home and commercial solar storage because they reduce current flow, allowing for smaller wires and higher efficiency over long distances.
