Envision unveils 12.5 MWh BESS, begins 790 Ah cell output

China’s Envision has launched a 12.5 MWh battery storage system and started production of a 790 Ah lithium iron phosphate (LFP) cell, as it advances an AI-driven storage strategy.

12.5MWh System – Fully Integrated with AI Energy Architecture

According to Envision, the newly launched 12.5MWh BESS integrates multiple core components:Battery cells/Power conversion systems (PCS)/ Battery management system (BMS)/ Energy management system (EMS)/ Supervisory control and data acquisition (SCADA)/Power trading tools.

All of these operate under what the company describes as an "AI energy systems" approach, which enables: Real-time optimization, Predictive maintenance, Automated participation in energy markets.

This sets a new benchmark for large-scale stationary storage, addressing the growing demand for grid stability and renewable energy integration.

Container Battery Designed for Solar Integration

Beyond utility-scale solutions, Envision also highlighted a new container battery for solar systems, specifically engineered for seamless integration with photovoltaic installations.

Key features:

Supports both DC-coupled and AC-coupled configurations

Enables reduced on-site installation time for solar project developers

Improves overall system reliability

The Lifepo4 container battery is fully compatible with the company's 1MWh energy storage system, making it an ideal choice for mid-sized solar-plus-storage projects.

790Ah LFP Cell – Now in Mass Production

At the core of the 12.5MWh system lies the 790Ah lithium iron phosphate (LFP) cell, which Envision confirms is now in mass production.

Energy density >440 Wh/L/ Cycle life >15,000 cycles/ Calendar life Up to 30 years/ Round-trip efficiency (cell level) 96%

With this high-performance cell now in mass production, Envision is positioned to address a wide spectrum of applications: Behind-the-meter commercial storage, Grid-scale renewable integration, Utility-scale energy storage projects

 The newly launched 12.5MWh system and 790Ah cell represent a significant step forward in LFP-based stationary storage, offering:

• Longer lifespan

• Higher efficiency

• Lower levelized cost of storage (LCOS)

These products are designed to meet the evolving needs of customers ranging from commercial and industrial (C&I) users to utility-scale project developers.
