OEM & ODM Service Procedures
Have you ever wondered how to do OEM & ODM for solar storage system step by step? Below are the procedures explaining from initial consultation to designing, production, testing, and shipping to customer hands.
Initial Project Consultation
Our sales and technical consultants begin by understanding your business model, target market, and project objectives. No matter you are a distributor, installer, EPC contractor, or brand owner, we discuss your application scenarios, expected product positioning, and market requirements. This initial consultation establishes a clear cooperation framework and helps us recommend the most suitable lithium battery or solar energy storage solution.
Requirement Analysis
Our engineering team conducts a comprehensive analysis of your technical requirements, including battery capacity, voltage, inverter compatibility, operating environment, backup time, installation method, and certification requirements. We also evaluate local grid conditions, climate, and applicable regulations to ensure the proposed solution fully meets your project needs.
Technical Feasibility Evaluation
Based on the requirements, our R&D and production teams evaluate the technical feasibility of every single project. We assess battery cell selection, BMS architecture, communication protocols (CAN/RS485/RS232), production capacity, certification compliance, raw material availability, and delivery schedules. This step ensures the proposed solution is technically reliable, commercially practical, and cost-effective.
Customized Solution Proposal
After completing the feasibility assessment, we prepare a complete customized solution, including product specifications, system configuration, wiring diagrams, recommended inverter models, battery capacity calculations, estimated performance, project timeline, and preliminary pricing. This proposal serves as the foundation for further technical and commercial discussions.


Product Design & Engineering
Our experienced R&D engineers begin detailed product development based on the approved proposal. This includes battery pack structure, electrical architecture, BMS programming, thermal management, communication interface design, and system integration. Every design is optimized for safety, efficiency, scalability, and long-term reliability.
Industrial Design & OEM Branding
We provide complete OEM and ODM customization services, including cabinet appearance, color selection, silk-screen logo printing, product labels, user interface design, packaging artwork, instruction manuals, and marketing materials. Our goal is to help customers build a strong local brand identity while maintaining international manufacturing standards.
Quotation & Commercial Confirmation
Once the technical solution is finalized, we issue a detailed commercial quotation covering product pricing, tooling costs (if applicable), MOQ, payment terms, production lead time, warranty policy, and shipping arrangements. Both parties review the contract to ensure every technical and commercial detail is confirmed before production begins.
Sample Production
Our production team manufactures prototype samples according to the approved specifications. Each sample is assembled using production-grade materials and manufacturing processes to accurately represent the final product. This allows customers to verify both product quality and functional performance before mass production.
Prototype Testing & Performance Validation
Each prototype undergoes comprehensive testing, including charging and discharging performance, battery capacity verification, BMS communication, inverter compatibility, temperature rise, safety protection, aging tests, and functional inspections. Additional environmental and reliability tests can also be conducted based on customer requirements.
Customer Approval & Final Optimization
Customer evaluates the appearance, functionality, and overall performance of prototypes. Based on customer feedback, our engineering team performs final optimizations if necessary. Once all technical specifications and quality standards are approved, the product design is officially frozen for mass production.
Mass Production Planning
Before manufacturing begins, our production management team prepares raw materials, battery cells, electronic components, production schedules, quality control plans, and workforce allocation. We coordinate every production stage to ensure efficient manufacturing while maintaining consistent product quality and on-time delivery.
Mass Production & Process Control
Our automated production lines manufacture each product according to strict ISO quality management standards. Every assembly process, including battery matching, welding, BMS installation, functional testing, and system integration, is monitored through standardized operating procedures to ensure consistency and reliability.


Comprehensive Quality Inspection
Every battery system undergoes multiple quality inspections before shipment, including appearance inspection, battery capacity testing, voltage balancing, insulation testing, communication verification, aging tests, safety inspections, and final functional testing. Only products meeting our strict quality standards proceed to packaging. Before shipment, products are accompanied by international certifications (such as IEC 62619/62040), user manuals, and warranty documents.
Packaging & Export Preparation
Qualified products are professionally packaged using export-grade materials to protect them during international transportation. Our logistics team prepares all required export documents, including commercial invoices, packing lists, MSDS, UN38.3 reports, certificates of origin, shipping labels, and customs documentation for smooth global delivery. All of the solar products are evaluated to meet international certifications (such as CE, CB, IEC62619, IEC62040, IEC61000, or UN38.3, MSDS standards).
Global Logistics & Delivery
We arrange the most suitable transportation method based on customer requirements, including sea freight, air freight, railway, or multimodal logistics. Customers receive real-time shipment updates and tracking information throughout the transportation process. We work with reliable logistics partners to ensure safe, timely, and cost-effective international delivery.
After-Sales Service & Technical Support
Our commitment continues after delivery. We provide installation guidance, remote technical support, commissioning assistance, warranty service, spare parts supply, software upgrades, and ongoing engineering consultation. Our professional after-sales team responds promptly to technical inquiries and helps customers maximize the long-term performance and value of their lithium battery and solar energy storage systems.
