A Manufacturing Partner Built for Global Brands
Headquartered in Taiyuan, China, Shanxi Yiwei New Energy coordinates production across three specialized regional bases — Sichuan for solar PV modules, Guangzhou for energy storage systems and battery PACK integration, and Inner Mongolia for portable power products. This multi-region model reduces single-point dependency and optimizes cost, quality, and lead times.
We serve global energy distributors, EPC contractors, system integrators, and brand owners with flexible engagement models — from fast-turnaround private labeling to full ODM product development with exclusive tooling and intellectual property.
Every product is backed by full lifecycle traceability: serial-number tracking, BMS data logging, and complete test records from incoming inspection through final shipment.
