Energy Storage Manufacturing Backed by Engineering and Production Capabilities
Choosing an energy storage supplier requires more than comparing battery specifications and prices. Global buyers need full transparency into how products are developed, manufactured, tested, and supported throughout their operational lifecycle.
Xinrex Energy Technology develops and manufactures advanced energy storage batteries and integrated energy solutions for residential, commercial, and industrial (C&I) applications. Founded in 2017, the company combines in-house R&D, robust engineering resources, and scalable manufacturing capabilities to meet diverse global energy storage requirements.
Our engineering and R&D operations are based in Dongguan, Guangdong, while our commercial energy storage and sodium-ion battery production base is located in Zhuhai. This strategic manufacturing layout supports continuous product innovation and efficient high-volume delivery across different global application scenarios.
Engineering and Manufacturing Capabilities
To provide reliable supply chain security, Xinrex maintains dedicated operational infrastructure:
Team & Facilities:
A team of nearly 200 employees, including over 50 R&D and technical professionals. Our Dongguan R&D center covers approximately 8,000 square meters, and the Zhuhai production base spans 10,000 square meters.
Production Capacity:
An annual energy storage production capacity of 4 GWh and a hybrid inverter production capacity of 36,000 units.
Product Scope:
Supporting residential battery systems (e.g., low-voltage 48V wall-mounted and rack-mounted modules), all-in-one integrated storage units, and large-scale C&I high-voltage container and cabinet energy storage systems.
Note:
Actual production capacity, available production slots, and tailored delivery schedules should be confirmed against selected product lines and active order requirements.
Advanced Battery Manufacturing and Process Control
Manufacturing consistency depends on strict quality control throughout cell assembly and system integration. Xinrex utilizes state-of-the-art automated equipment to ensure production stability:
Cell Sorting & Polarity Detection Systems: Ensuring tight voltage and capacity matching.
Module Stacking & Pole Cleaning Equipment: Guaranteeing mechanical precision and low contact resistance.
Laser Welding Equipment: Providing secure, high-integrity electrical connections.
Total Pressure & Internal Resistance Testing Equipment: Screening out performance anomalies early in the assembly phase.
Battery Aging Equipment: Conducting rigorous thermal and electrical cycling to ensure long-term field reliability.
Buyers are welcome to request specific process control plans, inspection checkpoints, and acceptance criteria applicable to their chosen model.
Rigorous Quality Inspection and Compliance Verification
For B2B procurement, quality assurance must be backed by documented inspection procedures and international compliance standards rather than general claims. Xinrex aligns its production with globally recognized standards (supporting requirements for UL, IEC, CE, and ISO quality management systems).
Depending on the product and agreed technical specification, buyers can review the following verification records:
• Incoming cell and component inspection records (IQC)
• Cell matching and electrical measurement data
• Assembly and welding process inspection logs
• Battery pack electrical and functional test results
• Battery aging and thermal stress test reports
• BMS communication and protection-function verification logs
• Final inspection reports and unique model traceability records
• Applicable third-party product test reports and international compliance documentation
Research, Development and Product Customization
Xinrex's R&D capabilities span energy storage hardware, inverter technology, advanced Battery Management Systems (BMS), Energy Management Systems (EMS), cloud-based monitoring platforms, and microgrid applications.
For project developers and distributors with specialized requirements, our engineering team collaborates on:
• Battery capacity and system voltage optimization
• Flexible mechanical installation configurations
• Customized communication protocols (CAN, RS485, Modbus, etc.)
• Hybrid/PCS inverter compatibility
• Integration with existing solar or diesel generator systems
Customization feasibility depends on the selected platform, target market regulations, and project volume. A comprehensive technical review is conducted prior to finalizing specifications and lead times.
Quality Documentation and Traceability for Procurement
Before approving a supplier, engineering and compliance teams require transparent documentation. Xinrex provides complete technical dossiers covering product specifications, testing methods, raw material traceability, and safety compliance.
During the technical evaluation stage, we assist procurement teams with required documentation reviews. Factory audits or third-party pre-shipment inspections (e.g., SGS, TUV) can also be arranged upon agreement.
