Vertically-integrated BESS manufacturer & lithium battery manufacturer — from 5kWh / 10kWh / 15kWh / 20kWh home energy storage & 48V LiFePO4 battery walls to 1MWh / 5MWh container BESS. Engineered, manufactured and serviced by SMS in China since 1996.
We've spent three decades building the technical depth, manufacturing scale, and after-sales network that distinguishes a serious supplier from a re-brander.
Owned cell selection, BMS hardware, PCS firmware, and container assembly. Two overseas factories (Italy & Brazil) plus China HQ — total annual capacity 5 GWh across BESS lines.
Cell-level fusing, three-stage thermal runaway protection, IP55 enclosures, perfluorohexanone fire suppression and aerosol systems. UL9540A tested at module & rack level.
Overseas warehouses in USA, Germany, Poland and Iraq (partner depot). Local engineers in 12 service hubs. 24/7 remote diagnostics via cloud EMS — average MTTR < 8 hours.
Four complete product lines built on a common LFP cell platform — sourced from tier-1 suppliers, verified through 10,000+ deep cycles.
Whether you're stabilizing a microgrid in remote Africa, peak-shaving a German factory, or backing up a residential solar array — we have a tested, certified product configuration.
From utility-scale grid backbones to private off-grid villas — our installed base spans 150+ countries. Here are a few we can talk about publicly.
