Established in 2014, Shenzhen Suntherra Battery Co., Ltd. has emerged as a titan in the Pearl River Delta’s renewable energy sector. With a 12,000 square meter state-of-the-art facility, we blend precision engineering with high-volume capacity to serve the global "High Performance" solar battery market.
Our team of 180+ professionals includes specialized battery chemists and electronic engineers focused on BMS (Battery Management System) optimization. We don't just assemble; we innovate to ensure safety, 6000+ cycle life, and thermal stability in extreme climates.
Adhering to strict international standards, our factory implements rigorous QC protocols from cell sorting to final capacity grading. Our products meet CE, UN38.3, and MSDS certifications, ensuring reliability for installers and distributors worldwide.
Why China remains the global hub for Solar Battery manufacturing and innovation.
As a leading solar battery factory, Suntherra leverages the world's most mature lithium-ion ecosystem. This proximity to raw material processors and component manufacturers allows us to offer:
Stay ahead of the curve with our vision for the next generation of energy storage.
Focusing on energy density increases and the transition to 300Ah+ large-capacity cells to reduce system complexity and cost per kWh.
Developing sodium-ion alternatives for low-temperature performance and cost-sensitive stationary storage applications, reducing lithium dependency.
R&D investment into semi-solid state electrolytes to eliminate fire risks and double the lifespan of industrial energy storage systems.
Integrating machine learning algorithms into the Battery Management System to predict cell failure and optimize discharge curves based on local grid patterns.
Moving from air cooling to liquid cooling for high-capacity C&I (Commercial & Industrial) containers to ensure 24/7 stability in tropical climates.
Sustainable initiatives to repurpose EV cells into stationary storage, maximizing the circular economy within the solar battery industry.
High Performance Solar Batteries engineered for diverse global environments.
Our "Power Wall" solutions allow homeowners in Europe and North America to maximize self-consumption from rooftop solar panels, providing 10kwh+ backup during grid outages.
Large-scale Ess Containers (up to 5MWh) help factories and offices reduce peak demand charges and participate in frequency regulation markets in developed economies.
In regions with unstable grids like Africa and SE Asia, our deep-cycle gel and Ni-CD batteries provide ultra-reliable 48V power for telecom base stations and micro-grids.
A high-performance battery is defined by three factors: Energy Density (capacity vs weight), Cycle Life (over 6000 cycles at 80% DOD), and Safety (LiFePO4 chemistry with advanced BMS thermal management).
Shenzhen is the global epicenter for lithium technology. Factories here, like Suntherra, have immediate access to the latest cell innovations, technical talent, and optimized shipping routes, ensuring a better price-to-performance ratio.
Yes. As a professional manufacturer, we offer full customization including battery capacity (kWh), voltage (12V-51.2V), casing design (wall-mounted, rack-mounted, or container), and branding/packaging.
We use Grade A cells only. Every battery pack undergoes automated laser welding and individual cell balancing. Our BMS protects against overcharge, over-discharge, short circuits, and overheating.
Standard lead times for bulk orders are 15-25 days, depending on the customization level. Our 12,000 sqm facility allows us to handle high-volume demands without compromising on QC.
