Vilion

What Vilion does

Vilion (深圳市未蓝新能源科技有限公司) is a Shenzhen-based, privately held manufacturer of lithium iron phosphate (LFP) battery energy storage systems (BESS) focused on commercial and industrial (C&I) customers. The company was founded in 2019 by former BYD R&D personnel including General Manager Shawn Song, who previously led a 200-person BYD team responsible for BESS products that held the #1 European/US grid-storage market share from 2013 to 2019. The core team brings ~16 years of electrochemical storage experience dating to 2007-2008.

Vilion's product portfolio is anchored on the Ener series — outdoor all-in-one cabinets (EnerArk and EnerArk-M at 60-120 kW / 125-241 kWh, EnerGeo at 30-60 kW / 38-76 kWh), the EnerCube containerized system (1000 kW / 1204 kWh, in 0.5C and 1C variants), and the EnerBC battery cabinet — all built around its proprietary AiP (Active in Parallel) cluster-balancing technology and a 2S+C stack of BMS, EMS, and a ViViewer cloud platform. The company holds over 30 patents and an extensive certification stack (IEC62477, CE, UN3536, VDE-2510, CEI021/016, ISO 9001/14001/27001, China Classification Society).

Vilion operates on a hardware-led, project-based revenue model selling integrated BESS to C&I customers for peak-valley arbitrage, demand-charge management, backup power, capacity expansion, and renewable integration. Revenue is supplemented by ViStarter EMS and ViViewer software (recurring/remote-monitoring economics) and by EPC and licensing arrangements with a South African exclusive channel partner covering Africa and the Middle East. The company sells directly in China and major international projects, holds wholly-owned subsidiaries in the Netherlands (2024) and the UK (2025), and leverages dealer networks for Chinese distribution. Cumulative scope includes over 100 projects across 23+ countries with >2 GWh of team-delivered capacity, including MW-scale deployments in Japan, Sweden, the UK, Australia, and China, and has received strategic investment from Japan's Itochu Corporation and a Top 50 Chinese venture capital institution.
