About Envision Energy
Envision Energy (Envision Group, Shanghai) is a wind-turbine OEM that also builds battery energy storage systems; LFP cells are produced by its majority-owned subsidiary Envision AESC (300+ Ah, 500+ Ah, 700+ Ah and, since April 2026, 790 Ah ESS cells). The company reports 400+ storage projects, >50 GWh of systems and >100 GWh of ESS cells delivered, and a BNEF Tier 1 listing. The current utility-scale portfolio comprises the Gen 7 5.03 MWh 20-ft liquid-cooled DC container on 315 Ah cells (with TwinSkid/SingleSkid MV AC skids of 3.3-6.9 MVA), the EN 5 Pro 2.5 MW / 5 MWh all-in-one string-PCS block, the EN 8 Pro 8 MWh DC container on 700 Ah-plus cells and the Gen 8 Scalable Platform (10-ft modular units, 750+ Ah, 6/8/10/12 MWh configurations, 10 MVA AC skid), announced October 2025 and contracted for German 4-hour projects in 2026. An EN 12.5 MWh AI storage system with 790 Ah cells was announced in April 2026. The older ENS-L modular liquid-cooled cabinet series (280/305 Ah, 4.47-9.75 MWh) appears in the 2024 brochure. Envision also sells C&I storage cabinets in China (>1,000 units delivered) but publishes no specifications for them. Only the 5.03 MWh container has a public datasheet (hosted on the India regional site); the global site is a JS application without spec sheets. Not disclosed: system-level round-trip efficiency, cycle-test conditions, warranty terms, weights and voltages of the Gen 8 and EN 5 Pro / EN 8 Pro units, and any usable-energy figures.
