The company focuses on the comprehensive development, precision production, and system integration of lithium-ion battery technology designed to support renewable energy utilization, peak shaving, emergency backup power supply, and smart energy management projects worldwide.
With an unwavering commitment to innovation, structural safety, and thermal management excellence, PowerSTN provides a diverse portfolio of energy storage products. Our engineering scope spans stackable residential energy storage systems, modular C&I battery enclosures, high-capacity solar energy storage batteries, off-grid power stations, hybrid energy storage platforms, and megawatt-scale containerized battery energy storage systems (BESS). These solutions are engineered to help utility providers, EPC contractors, and corporate enterprises improve energy efficiency, enhance grid stability, and maximize the financial return on renewable energy investments.
The company operates modern manufacturing facilities equipped with automated cell-sorting lines, laser welding robotics, fully automated BMS testing stations, and rigorous environmental simulation chambers. From raw battery cell selection (utilizing top-tier prismatic LiFePO4 cells) and module pack assembly to complex multi-tier system integration and full-load thermal testing, every stage of production is meticulously controlled under ISO9001, ISO14001, and ISO45001 quality management systems to guarantee operational reliability, fire safety, and long-term performance.
PowerSTN actively serves enterprise customers across multiple core sectors, including solar-plus-storage installers, telecommunications infrastructure, hyperscale data centers, utility operators, industrial manufacturing facilities, and municipal energy projects. Our dedicated R&D engineering team collaborates closely with international clients to deliver fully customized OEM and ODM energy storage solutions tailored to unique thermal environments, grid codes, and operational parameters.
Beyond baseline contract manufacturing, Shenzhen PowerSTN Energy Co., Ltd. delivers complete end-to-end OEM and ODM support for global brands, distributors, power system integrators, and independent power producers (IPPs). By combining deep electrochemical expertise, agile production scalable up to gigawatt capacity, and customer-centric technical support, PowerSTN serves as a trusted strategic partner for organizations seeking scalable, certified, and bankable energy storage technologies in the rapidly evolving global energy transition market.
We source exclusively Grade-A prismatic Lithium Iron Phosphate (LiFePO4) cells featuring high energy density, thermal stability up to 500°C, and operational lifespans exceeding 6,000 to 10,000 deep charge-discharge cycles.
Proprietary Battery Management Systems with real-time SOC/SOH algorithm estimation, active balancing, multi-point temperature sensing, and remote telemetry via CAN, RS485, and Ethernet protocols.
Integrated air-cooling HVAC and liquid-cooling cooling plate options designed to maintain cell temperature delta under 3°C, extending pack life and preventing localized thermal hotspots.
Analyzing macroeconomic drivers, supply chain dynamics, and technical specifications governing international energy storage procurement.
The global shift toward decentralized energy generation has elevated Battery Energy Storage Systems (BESS) from auxiliary power units to core infrastructure assets. Multi-national corporations, industrial park operators, and utility providers face dual pressures: navigating volatile spot-market electricity prices while fulfilling stringent corporate net-zero carbon mandates. Industrial and Commercial (C&I) facilities are increasingly procuring high-capacity energy storage solutions to facilitate Peak Shaving, Load Shifting, and Demand Charge Reduction.
By absorbing excess renewable power during off-peak windows or low-cost generation periods and discharging during peak demand hours, commercial enterprises can reduce annual utility charges by 20% to 45%. Furthermore, in regions prone to grid instability, microgrid-integrated lithium storage systems safeguard continuous manufacturing lines against costly voltage sags and blackouts.
Procurement directors and system integrators mandate absolute technical clarity before entering OEM/ODM supply agreements. Key engineering criteria evaluated during factory audits include:
From initial CAD modeling and firmware customization to full-scale automated assembly and international certification support.
Engineered structural enclosures tailored to specific NEMA 3R/4X or IP55/IP66 ratings. Options include custom sheet metal stamping, anti-corrosion marine-grade coatings (C4/C5 durability), stackable footprints, and containerized 20ft/40ft ISO designs.
Firmware tailored to support Modbus RTU, Modbus TCP, CANbus 2.0B, and SunSpec standards. Custom cloud telemetry, Remote Web UI, integration with third-party hybrid inverters (e.g., Deye, Victron, SMA, Growatt, Sol-Ark), and proprietary SOC algorithms.
Modular architectures engineered from low-voltage (48V/51.2V residential modules) up to high-voltage (up to 1500V DC containerized systems) with customizable capacity configurations (from 5kWh home systems to 5MWh energy blocks).
Our collaborative production model ensures complete transparency, strict IP protection, and expedited time-to-market for enterprise clients:
Detailed load profile assessment, cell cycling simulation, electrical schematic layout, and initial thermal simulation (CFD analysis).
Rapid fabrication of functional engineering samples, BMS firmware tuning, vibration resistance testing, and thermal runaway testing.
Submission of prototypes to accredited laboratories (TÜV, Intertek, SGS) for UL1973, UL9540, UL9540A, IEC62619, and UN38.3 certification.
