What Shenzhen Sinexcel Electric does

Shenzhen Sinexcel Electric Co., Ltd. is a publicly listed (Shenzhen Stock Exchange ChiNext, ticker 300693) Chinese power electronics company founded in 2007 that designs, manufactures, and sells electrical equipment across four business lines: power quality (active power filters, static var generators, UPS, dynamic voltage regulators), EV charging and battery swapping (DC fast chargers, flexible shared supercharging stacks up to 2,500kW, SiC-based charging modules, battery-swap cabinets), energy storage microgrids (PCS/converter products from 30kW C&I to 5MW utility-scale), and battery formation and testing equipment. The company is vertically integrated in core power modules — including self-developed silicon carbide (SiC) semiconductors achieving 97%+ efficiency on EV charging modules and 99% on energy storage converters — and applies a modular, hot-swappable architecture pioneered since 2008 that supports N+1 redundancy and scales from kilowatt to multi-megawatt systems. Sinexcel sells primarily through enterprise field sales and strategic channel partnerships (including China National Petroleum, Shell/Shell BYD JV, DiDi Charging, and Dongfeng Liuzhou), with project-based quote pricing on multi-year contracts, and serves utilities, industrial operators, data centers, EV charging operators, fleet operators, and battery manufacturers across 60+ countries. Headquartered in Shenzhen with manufacturing in Huizhou, an R&D center in Xi'an, and an East China operations center in Suzhou, the company operates 30+ global offices, has deployed 17GW/50GWh+ cumulative capacity across 5,000+ projects, and was added to BloombergNEF's Tier 1 Global Power Inverter Manufacturer list in 2026.
