The global transition toward Net-Zero Carbon emissions has positioned green energy batteries as the cornerstone of modern infrastructure. As a premier CE Certified Green Energy Battery Supplier, we recognize that the industry is no longer just about storage; it is about intelligent energy management and resilience. From the surge in EV adoption to the massive requirements of Industrial and Commercial (I&C) energy storage systems (ESS), the demand for high-cycle, safe, and efficient lithium iron phosphate (LiFePO4) technology is at an all-time high.
Currently, the market is shifting from lead-acid legacy systems to lithium-based solutions due to their superior energy density and lifespan. This "Lithium Revolution" is driven by two major factors: the lowering of levelized cost of storage (LCOS) and the stringent safety standards like CE, UL, and UN38.3 that ensure global trade compatibility. For enterprises, sourcing from a reliable supplier means securing the reliability of their power grid against price volatility and energy shortages.

Shenzhen is the global epicenter of battery innovation. By being located in this hub, Suntherra integrates the entire supply chain from raw lithium cell procurement to advanced BMS design, ensuring lower lead times and higher cost-efficiency for our global partners.
Our 12,000 sqm factory utilizes automated production lines that minimize human error. Every module undergoes rigorous OCV/IR testing, capacity grading, and aging tests before shipment, meeting the highest CE certification standards.
Unlike standard trading companies, our factory offers deep customization. From customized voltage configurations (12V to 800V) to specific BMS communication protocols (CAN, RS485, RS232), we tailor solutions to local application needs.
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.
Our main product range includes solar lithium batteries, deep cycle batteries, gel batteries, AGM batteries, off-grid energy storage systems, hybrid solar storage batteries, and high-capacity residential and commercial energy storage solutions. These products are widely used in solar power systems, home energy storage, industrial backup power, telecommunications, and outdoor renewable energy applications.
As an experienced OEM and ODM factory, Shenzhen Suntherra Battery Co., Ltd. provides customized solutions including battery capacity design, BMS (Battery Management System) integration, voltage configuration, structural optimization, branding, and packaging services. We work closely with global distributors, solar system integrators, wholesalers, and energy solution providers.
With high electricity prices in Germany and Italy, our stackable high-voltage systems (5kWh-30kWh) allow homeowners to maximize self-consumption from PV arrays, providing ROI within 5-7 years.
For commercial and industrial sectors, peak shaving is critical. Our 215kWh and 1MWh ESS cabinets provide demand charge management, helping factories reduce monthly utility bills significantly.
In regions with unstable grids, our 48V 100Ah/200Ah LiFePO4 batteries replace traditional lead-acid at base stations, offering 10x the cycle life and superior performance in high-temperature environments.
The next decade will see the integration of AI-driven Energy Management Systems (EMS) and the rise of Solid-State Batteries. We are already investing in "Second Life" battery technology and circular economy practices to ensure that green energy remains sustainable throughout its entire lifecycle. Smart grid interaction (V2G - Vehicle to Grid) is becoming a standard requirement for large-scale energy battery suppliers.
CE certification ensures that the battery complies with European safety, health, and environmental protection standards. It is a mandatory requirement for entering the EU market and a hallmark of quality for global buyers.
We use Grade A LiFePO4 cells and a proprietary BMS that balances cells during every charge/discharge cycle. This extends the lifespan to over 6000 cycles at 80% DOD (Depth of Discharge).
Yes, we provide full OEM/ODM services, including private labeling, customized casing colors, and specialized technical documentation tailored to your brand's market requirements.
GEL batteries are cost-effective for standby applications, while Lithium (LiFePO4) offers higher energy density, faster charging, and a much longer cycle life for daily solar cycling.
Absolutely. Our 500kW/1MWh systems are modular and can be connected in parallel to meet multi-megawatt requirements for grid-scale energy storage projects.
For standard models, lead time is 15-20 days. For customized industrial solutions, it typically ranges from 30-45 days depending on the complexity and volume.
