We provide fully tailored OEM/ODM solutions including battery capacity design, BMS integration, voltage configuration, structural optimization, branding, and packaging services. Our footprints span Europe, North America, Africa, and Southeast Asia, driving a cleaner, greener global energy transition.
Scalable industrial BESS containers, stackable home modules, and tubular Gel OpzV batteries built for heavy-duty deployment.
Understanding chemical compositions, BMS innovations, and macro trends driving utility and residential energy storage.
While traditional VRLA, AGM, and Tubular Gel (OpzV) batteries remain cost-effective stalwarts for telecom backup and rugged off-grid environments delivering up to 3000 cycles, Lithium Iron Phosphate (LiFePO4) represents the zenith of modern residential and commercial deployment. Offering 6000+ cycles, 98% round-trip efficiency, and thermal stability, LiFePO4 dominates future renewable roadmaps.
Advanced Battery Management Systems (BMS) integrate active balancing, Bluetooth diagnostics, IP65 waterproof ratings, and multi-module parallel support (up to 16 units for wall-mounted power walls or megawatt-scale BESS containers). This ensures absolute cell protection against over-voltage, short-circuits, and thermal runaway.
Sourcing from top-tier Chinese manufacturers requires rigorous international standard adherence (CE, UL, UN38.3, IEC62619, RoHS). Suntherra ensures complete export documentation, hazardous material shipping compliance, and localized technical support for distributors and EPC contractors across global markets.
Expert answers regarding customization, cycle life, warranty, and containerized energy storage integration.
Our LiFePO4 batteries deliver 4,000 to 6,000+ cycles at 80% Depth of Discharge (DoD), translating to an operational lifespan of 10-15 years. Our Tubular Gel (OpzV) and premium AGM/VRLA solar batteries offer 1,500 to 3,000 cycles depending on environmental conditions and maintenance.
Yes. As a direct factory with 12,000㎡ of production capacity, we provide comprehensive OEM/ODM services including custom casing colors, private logo silk-screening, custom BMS communication protocols (CAN/RS485 for major inverters like Deye, Growatt, Victron), and tailored voltage configurations.
Our products comply with strict international safety and quality standards, holding certifications including CE, UN38.3, MSDS, IEC62619, UL, and ISO9001 quality management system audits, ensuring smooth customs clearance worldwide.
We support flexible cooperation models. For standard catalog models, sample orders of 1-2 units are welcomed. For customized OEM/ODM projects (such as custom logo or specialized BMS), MOQs start from modest batch sizes tailored to support growing distributors and system integrators.
